DETAILED DESCRIPTION

This application is directed, at least in part, to a device having improved motion sensing, audio capturing, video capturing, and illumination capabilities. In some instances, the device includes a camera assembly, one or more light assemblies, and a mount. The camera assembly may include a camera oriented to capture images and/or video within an environment of the device, and/or passive infrared (PIR) sensor(s) arranged to detect motion within the environment of the device. Additionally, the camera assembly may include microphones for capturing audio, as well as a speaker for outputting sound. The light assemblies may include lighting elements configured to illuminate at least a portion of the environment. For example, in response to detecting motion within the environment, the light assemblies may be configured to illuminate and output light. The camera assembly and/or the light assemblies may be rotationally and/or pivotably coupled to the mount for changing an orientation of the camera, the PIR sensor(s), and/or an illumination area, respectively. The mount, for example, may be mounted on a surface (e.g., wall) for disposing the device on the surface. The arrangement of the camera, the PIR sensors, and the lighting elements may permit the device to more accurately sense motion, record images and/or video, and/or illuminate the environment, respectively.

The camera assembly, as indicated above, includes the camera configured to capture image and/or video data within the environment. Additionally, the PIR sensor(s) may be used to detect motion within the environment. In some instances, the camera and the PIR sensor(s) are oriented towards a front of the camera assembly. In some instances, the PIR sensor(s) may be in a vertically stacked relationship compared to one another. For example, a first PIR sensor may reside vertically above a second PIR sensor. In some instances, the PIR sensor(s) are vertically aligned on the device. In some instances, the camera may be vertically aligned with the PIR sensor(s).

The camera assembly may include a camera housing, a front cover, and/or a sensor lens. In some instances, the front cover may couple to the camera housing, and the sensor lens may couple to the front cover. The camera and/or the PIR sensor(s) may be disposed within the camera housing. The sensor lens, or a portion thereof, may include a Fresnel lens for directing incoming light rays to the first PIR sensor and the second PIR sensor, respectively. In some instances, the Fresnel lens is made up of a plurality of individual lens elements having respective focal lengths, centers, concentric grooves, and so forth for manipulating (e.g. increasing) a FoV of the PIR sensor(s). For example, the individual lens elements of the Fresnel lens array may include surfaces at different angles corresponding to different focal lengths and centers that direct light rays (e.g., radiation) onto the PIR sensor(s) from different locations throughout the environment.

In some instances, the front cover defines a window having an upper portion and a lower portion. A divider of the front cover may be disposed between the upper portion and the lower portion, so as to separate the upper portion and the lower portion. The sensor lens may couple to the front cover and be transmissive to light rays for sensing via the PIR sensor(s). For example, the first PIR sensor may receive first light rays via the upper portion of the window, while the second PIR sensor may receive second light rays via the lower portion of the window. The divider disposed between the upper portion and the lower portion may prevent light rays directed towards the first PIR sensor interfering (e.g., cancelling out) with light rays directed towards the second PIR sensor. In some instances, the divider may also include scalloped-shaped features to reduce a glare or reflection of the incoming light rays.

In some instances, the camera includes a substantially similar FoV as the PIR sensor(s). For example, the PIR sensor(s) may be configured to detect motion within a FoV, and the camera may have a FoV that is the same as, or substantially overlaps with, that of the PIR sensor(s). That is, the first PIR sensor and the second PIR sensor may have a collective FoV, and the camera may have a FoV that aligns with the collective FoV of the first PIR sensor and the second PIR sensor. In doing so, as the first PIR sensor and/or the second PIR sensor sense motion, the camera is able to capture image data and/or video data associated with the motion. In some instances, the camera is configured to capture image data and/or video data in response to motion be detected.

The PIR sensors are configured to output a signal or sensor data, and the device may use a characteristic determined using the signal or sensor data to determine whether the PIR sensor detected an object. For example, the characteristic may include a voltage represented by the signal or sensor data, an amplitude of a wave generated or determined using the signal or sensor data, an angle of the wave generated using the signal or sensor data, and/or the like. The device may then use characteristics determined using the signal or sensor data from multiple PIR sensors to determine a distance to the object.

While the PIR sensors may sometimes be described as having a collective FoV, the PIR sensors may individually have separate FoVs. For example, the first PIR sensor may have a first FoV that extends a first distance from the device. The second PIR sensor may have a second FOV that extends a second distance, closer to the device, than the first FoV, and/or a third FoV that extends a third distance, closer to the device, than the second FoV. As such, the first PIR sensor may be responsible for detecting motion within the first FoV, while the second PIR sensor may be responsible for detecting motion within the second FoV and the third FoV. In some instances, the FoVs of the PIR sensors may be non-overlapping.

By including different FoVs for the PIR sensors, the device is able to detect objects when the objects are located close to the device (e.g., within 1 meter) and when the objects are located farther from the device (e.g., twenty meters). For example, when an object is located at a first, distant location from the device, the first PIR sensor is able to detect the object while the second PIR sensor may not. As such, the device may determine that the object is within a certain distance from the device based on the object being detected within the first FoV. Likewise, when the object is located at a second, proximate location from the device, the second PIR sensor is able to detect the object while the first PIR sensor may not. Here, the device may determine that the object is a certain distance from the device.

Additionally, in some instances, the PIR sensors may be individually configured depending upon a desired FoV of the device. For example, if a user of the device desires short-range detection, the user may deactivate or disable the first PIR sensor. Here, only the second PIR sensor may be used to detect motion within the second FoV and/or the third FoV. Comparatively, if the user desires long-range detection, the user may deactivate or disable the second PIR sensor. Here, only the first PIR sensor may be used to detect motion within the first FoV. However, the user may also enable both the first PIR sensor and the second PIR sensor for short and long range detection.

In some instances, the FoVs of the PIR sensors may be defined in terms of tiers. The first FoV may be associated with a first tier, while the second FoV and the third FoV may be associated with a second tier located below the first tier. For example, the first tier may be associated with long-range detection, while the second tier may be associated with short-range detection. In some instances, the different tiers may help the device to detect motion over a wide range (e.g., close to the device and spaced apart from the device), and/or allow the device to more accurately detection motion at certain distances from the device. Further, separating the FoVs into tiers allows the device to monitor short-range and long-range motion.

A PIR sensor may include, for example, two pyroelectric sensing elements. Each pyroelectric sensing element may comprise a pyroelectric crystal that generates an electrical charge in response to a change in temperature. Radiation (e.g. infrared light) received at a surface of a pyroelectric sensing element causes a change in temperature, which, in turn, generates an electrical charge. Stated alternatively, an absorbing layer of a pyroelectric sensing element transforms radiation flux change into a change in temperature and a pyroelectric component performs a thermal to electrical conversion. One or more low-noise and low leakage current field-effect transistors (e.g. a JFET) or operational amplifiers are used to convert charge into a signal voltage.

In some instances, the two pyroelectric sensing elements may be electrically coupled together with opposite polarization to produce an output. In this way, an equal change in temperature at both of the pyroelectric sensing elements will cancel out in the output signal, thus filtering out temperature changes in the environment. However, a change in temperature at only one of the pyroelectric sensing elements will result in an output signal that is positive or negative (depending on which pyroelectric sensing element experienced the change in temperature).

In some instances, the PIR sensor may include two slots, each providing an optical path to one of the pyroelectric sensing elements. As discussed herein, a Fresnel lens array is configured to direct light received at the Fresnel lens array towards one or both of the pyroelectric sensing elements.

The PIR sensors may be analog, with an analog signal output, or may be digital, with digital data output generated utilizing an analog-to-digital converter (ADC).

A device may include the PIR sensors to detect objects. Each PIR sensor may output a signal or sensor data, where the device uses a characteristic determined using the signal or sensor data to determine whether the PIR sensor detected an object. The characteristic may include a voltage represented by the signal or sensor data, an amplitude of a wave generated or determined using the signal or sensor data, an angle of the wave generated using the signal or sensor data, and/or the like.

In accordance with one or more preferred implementations, a PIR sensor includes an integrated circuit (IC) component that receives voltage inputs from one or more lines coupled to a first PIR sensing element and a second PIR sensing element. In accordance with one or more preferred implementations, the IC component receives an input from each sensing element, while in accordance with one or more preferred implementations, the IC component receives a summed voltage.

In accordance with one or more preferred implementations, the IC component determines whether a summed voltage or an absolute value of a summed voltage exceeds a first threshold, and, if so, sends a logic signal (e.g. a Boolean value or an interrupt) to a controller (e.g. a microcontroller unit or MCU) of an electronic device.

In accordance with one or more preferred implementations, the IC component determines whether a difference between a current summed voltage and a previous summed voltage (e.g. at an immediate preceding time t−1) (or an absolute value of a difference between a current summed voltage and a previous summed voltage) exceeds a first threshold, and, if so, sends a logic signal (e.g. a Boolean value or an interrupt) to a controller (e.g. a microcontroller unit or MCU) of an electronic device.

In accordance with one or more preferred implementations, based on a received logic signal, the controller begins periodically polling or requesting PIR data (e.g. a most recent data value at the time of polling) from the IC component. For example, the controller may poll the IC component at a rate of 64 Hz.

In accordance with one or more preferred implementations, an electronic device is configured to allow a user to set a configuration setting enabling all PIR sensors or independently enabling or disabling a single PIR sensor, e.g. disabling a first PIR sensor while leaving a second PIR sensor enabled, or vice versa.

Fresnel lenses are commonly used in optics as a way to focus light, e.g. infrared light. An exemplary Fresnel lens has a smooth exterior surface and an interior surface having surface features (e.g. a curved surface) that causes refraction of light rays that pass through that feature. These surface features may be curved surfaces having a curvature designed to direct light to a focal point. Features or lens portions designed to direct light to a focal point may be characterized as lens facets. The curved nature of these facets may cause the thickness of a lens at a perimeter or side of one facet to be mismatched from the thickness of the lens at a perimeter or side of an adjoining facet. These mismatched “heights” may be connected together by a surface that can be characterized as a translation edge.

In accordance with one or more preferred implementations, facets and translation edges of a Fresnel lens may resemble, form, or represent grooves in a surface of the Fresnel lens. In some instances, these grooves may take the form of concentric arcs. These concentric arcs may be defined relative to a centerpoint that corresponds to a focal point for the lens.

In accordance with one or more preferred implementations, a Fresnel lens may comprise a plurality of lens sections that each have their own focal point. A lens section may include curved surfaces shaped and dimensioned to direct light onto the respective focal point of the lens section. A lens section may comprise facets and translation edges that resemble, form, or represent grooves in the shape or pattern of concentric arcs defined relative to a centerpoint that corresponds to a focal point for the lens section.

In accordance with one or more preferred implementations, a Fresnel lens comprising a plurality of lens sections is arranged in front of first and second PIR sensors, with a first plurality of the lens sections (e.g. a top row of lens sections) being shaped, dimensioned, and positioned to direct light onto the first PIR sensor, a second plurality of the lens sections (e.g. a middle row of lens sections) being shaped, dimensioned, and positioned to direct light onto the second PIR sensor, and a third plurality of the lens sections (e.g. a bottom row of lens sections) being shaped, dimensioned, and positioned to direct light onto the second PIR sensor.

For example,FIG.30illustrates an example Fresnel lens array3000comprising a plurality of Fresnel lens sections3002each having a respective centerpoint3004indicated with a plus (+). Each Fresnel lens section3002includes a corresponding focal point displaced out of the page (which can be characterized as being displaced along a z-axis, given an x-axis corresponding to a width of the page and a y-axis corresponding to a height of the page).

In some instances, the Fresnel lens array3000may include individual lens elements that are assembled together to form the Fresnel lens array3000. That is, in some instances, lens elements or lens sections may be individually formed, and thereafter, may be assembled together to form a Fresnel lens or lens array. These individual lens elements or sections, as noted above, may include respective concentric grooves

In some instances, a Fresnel lens or Fresnel lens array may include multiple focal lengths. Stated alternatively, lens sections or elements may include different focal lengths. However, the lens sections or lens elements that make up a Fresnel lens or Fresnel lens array may have a common focal point for sensing via PIR sensor(s). As such, the PIR sensor(s) may be located at the focal point.

In some instances, a Fresnel lens or lens array is configured to direct light rays to two PIR sensors. A Fresnel lens array may be symmetrical about a central axis/plane, such that a first half includes the same (or similar) lens elements (and translation edges) as a second half. Although described as directing light rays to two PIR sensors, a device (or other system) employing a Fresnel lens or lens array may include more than or less than two PIR sensors.

As introduced above, lens elements or sections may couple to one another in order to form the Fresnel lens array3000. In some instances, the lens elements may be adhered to one another, bonded to one another, sonically welded to one another, and so forth. However, although described as being separate lens elements that are individually formed from separate pieces of material, in some instances, a Fresnel lens or lens array may be made up of a single piece of material, and the lens elements or sections with the different concentric grooves may be formed within the single piece of material. In this instance, the individual lens elements or sections may not be coupled together to form the Fresnel lens or lens array, but the Fresnel lens or lens array may include a unitary structure with facets and translation edges defining concentric grooves being formed therein.

In some instances, individual lens elements or sections may include different or similar shapes and/or sizes compared to one another. For example, certain lens elements or sections may be square-shaped, while other lens elements may be rectangular-shaped, or have curved edges, etc.

In accordance with one or more preferred implementations, a mold for a Fresnel lens or lens array is manufactured by using a diamond lathe, and the mold is used to injection mold a lens or lens array. In some instances, a lens is formed from HDPE, silicon, germanium, zinc-sulfide, or zinc-selenide.

Each of the FoVs of the PIR sensors may be characterized as including detectable zones. The detectable zones collectively define the FoVs. In accordance with one or more preferred implementations, the detectable zones may be characterized as being polarized (e.g., positive and negative detectable zones). For example, the first FoV may include a plurality of first detectable zones, the second FoV may include a plurality of second detectable zones, and/or the third FoV may include a plurality of the third detectable zones. As objects enter the detectable zones, the PIR sensors generate voltage values (positive or negative) indicative of motion being sensed within the detectable zone.

More specifically, the PIR sensors may have two slots, where each slot provides access to a pyroelectric element that is sensitive to IR. When the PIR sensors are idle, both slots detect the same amount of IR (e.g., the amount of IR radiated from walls, outdoors, etc.). However, when an object, such as a person, comes within the first FoV or the second FoV, IR of the person is intercepted by the first PIR sensor or the second PIR sensor. That is, as the person enters a detectable zone of the first FoV, the second FoV, or the third FoV, in response, a positive differential exists. Comparatively, when the person leaves the detectable zone of the first FoV, the second FoV, or the third FoV, the reverse happens, whereby the first PIR sensor or the second PIR sensor generates a negative differential change. These positive and negative signals are therefore used to indicate whether the person is entering or leaving the first FoV, the second FoV, or the third FoV.

In some instances, the device may determine values associated with the signals or data generated by the PIR sensor(s). For example, a first signal represented by first sensor data may include a first waveform and a second signal represented by second sensor data may include a second waveform. The device may analyze the first waveform to determine a first value (e.g., amplitude, angle, etc.) and/or may also analyze the second waveform to determine a second value (e.g., amplitude, angle, etc.). The difference in the infrared levels between first value and the second value may then be measured in order to detect the presence of the object.

By way of further illustration, as a person passes across the first FoV in a left to right direction, in front of the device, and comes within a first detectable zone of the plurality of first detectable zones, IR light will be directed to a first pyroelectric sensing element of the first PIR sensor, causing the first PIR sensor to output a signal or data based thereon. This signal may output by the first PIR sensor may be positive to indicate entry of the person into a detectable zone (or the FoV). A second detectable zone of the plurality of first detectable zones, however, does not receive the IR light, and accordingly, motion is detected. That is, because a difference exists between the first detectable zone and the second detectable zone, motion is sensed. Thereafter, during continued movement of the person, the person leaves the first detectable zone of the plurality of first detectable zones comes within the second, adjacent, detectable zone of the plurality of first detectable zones. Here, IR light will be directed to the second pyroelectric sensing element of the first PIR sensor, causing the first PIR sensor to output a signal or data based thereon. This signal may be negative to indicate an exit from the first detectable zone of the plurality of first detectable zones and an entrance into the second detectable zone of the plurality of first detectable zones. In other words, the signal may be sum of a first negative signal generated by the first pyroelectric sensing element of the first PIR sensor (e.g., indicative of the person leaving the first detectable zone) and a second negative signal generated by the second pyroelectric sensing element of the first PIR sensor (e.g., indicative of the person entering the second detectable zone).

However, in approach detection, for example, as the person nears the device, the output signals and/or data may cancel out. For example, positive and negative detectable zones may generate signals that cancel each other out. In such instances, the device may fail to detect motion of the object. In an effort to overcome these shortcomings, the detectable zones of the first FoV may be offset from the detectable zones of second FoV and/or the third FoV. (It will be appreciated that each of these detectable zones may itself be characterized as a field of view, e.g. a field of view provided by a first lens section for a first pyroelectric crystal received within a first slot of a PIR sensor). For example, the detectable zones of the first FoV may be azimuthally or horizontally offset (e.g., shifted) from the detectable zones of the second FoV and the third FoV. In some instances, the detectable zones of the second FoV and the third FoV are horizontally aligned. More generally, zones of the tier of the first FOV may be azimuthally offset from zones of the tier of the second FoV and the third FoV. Offsetting the detectable zones of the first FoV causes the detectable zones of the first FoV to not overlap with the detectable zones of the second FoV and/or the third FoV, thereby permitting the device to sense motion in the first FoV (e.g., without signals cancelling out).

In some instances, the first FoV, the second FoV, and/or the third FoV are created using the Fresnel lens. That is, as noted above, the Fresnel lens may direct light to the first PIR sensor and/or the second PIR sensor. The Fresnel lens may define features that are utilized to direct light from the various FoV onto one of the PIR sensors. The Fresnel lens may be shaped, positioned, oriented, and configured to direct light from a particular FoV onto a particular one of the PIR sensors.

While described with respect to PIR sensors, in other examples, the any other type of motion detector may be utilized. For example, the camera assembly may include one or more active IR sensor(s) oriented towards the front of the camera assembly. In some instances, the active IR sensor(s) may include two IR sensor(s) disposed beneath the front cover that are configured to emit IR light through a portion of the front cover. As such, the IR sensor(s) may emit signals (e.g., IR light) through at least a portion of the front cover and may receive the signals to detect IR radiation. As such, at least a portion of the front cover is transmissive to signals emitted from, and received by, the IR sensor(s).

The camera assembly may also include microphone(s) for capturing audio within the environment, speaker(s) for outputting sounding within the environment, ambient light sensor(s) for detecting lighting conditions within the environment, lighting elements configured to output light indicative of operations being performed by the device, button(s) that at least partially control an operation of the device (e.g., volume, sync, reset, turn on/off, etc.), and so forth. In some instances, the microphone(s) may be oriented towards the front of the camera assembly, and/or the speaker may be oriented to emit sound outward from a side of the camera assembly. The speaker may include any suitable speaker, such as a tweeter, mid-range, or subwoofer. In some instances, the lighting elements may illuminate to different colors of light, different patterns of light, and so forth depending on the operational state of the device. Additionally, the camera assembly may include computing components, such as network interfaces, for communicatively coupling the device to one or more additional devices, as well as other computing components that enable operation of the device.

The light assemblies may include various light emitting diodes (LEDs) for illuminating an environment. In some instances, the light assemblies include a first light assembly and a second light assembly. Flood LEDs (e.g., visible light) may be disposed within the light assemblies. In some instances, the light assemblies include a light housing in which the LEDs reside. The light housings may be coupled to the mount via arms, respectively. The light assemblies may be rotatably coupled to the arms, respectively, while the arms may be rotationally coupled to the mount. As such, an illumination FoV of the light assemblies may be independently adjustable via an engagement between the light housings with the arms, and the arms with the mount. Wires, or other cables, may route through the arms, between the mount and the light housings, respectively, for communicatively coupling the light assemblies to the camera assembly. Additionally, the light assemblies may be communicatively coupled to PCBs within the mount (e.g., for receiving power).

In some instances, the light assemblies couple to the arms via a ratchet mechanism having teeth and a coupler. The teeth may be disposed on the arm, while the coupler may couple to the light housing. The coupler engages with the teeth. For example, the light housings may define a receptacle into which at least a portion of the arm is disposed, and within the light housing, the coupler may engage with the teeth. In some instances, the coupler includes a notch that engages with the teeth. The engagement between the notch and the teeth allows the light housing to be rotated for reorienting the light assemblies. During such occurrences, the notch may traverse over or along the teeth. As the notch traverses over the teeth, haptic feedback may be provided to the user.

In some instances, the mount may couple to the device to dispose the device on a vertical surface (e.g., wall). In some instances, the mount may couple to the camera housing. In some instances, the mount couples to a junction box, and receives power (or other cables) via the junction box. In some instances, the camera housing couples to the mount via a ball and socket joint. Such coupling allows the camera housing to pivot, rotate, and so forth for changing a FoV of the camera, the PIR sensor(s), and so forth. In some instances, the wires that provide power to the device may be routed at least partially through the ball and socket joint.

The device may also include heat dissipating elements to disperse heat generated by components of the device. By way of example and not limitation, the camera(s), LEDs, power supply, network interfaces, and so forth generate heat during use. Without effectively dispersing or dissipating this heat, the internal components, such as the camera, may be adversely effected and become uncappable of performing its intended function. To efficiently dissipate heat generated by the components, heat dissipating elements may be included within the camera housing and/or the light housings to transmit heat away from generating sources.

The camera assembly102on the light assemblies104may be communicatively coupled to one another (e.g., via wires). The lighting elements of the light assemblies104may be disposed beneath windows130, such as a first window130(1) of the first light assembly104(1) and a second window130(2) of the second light assembly104(2), respectively.

As shown, and in some instances, the light assemblies104may be located vertically above the camera assembly102.

The mount106may couple the device100to, or dispose the device100along, a surface (e.g., wall). For example, the mount106may be mounted to the surface such that the device100may hang from the surface. In some instances, the mount106may couple to a junction box, for example, to receive power and to route the power to components of the device100. In some instances, the mount106may include an internal connection that couples the power to wires of the device100. The mount106may also include computing components (e.g., capacitors, PCBs, etc.) for supplying power to the camera assembly102and the light assemblies104.

Additionally, the camera assembly102and the light assemblies104may be pivotably coupled to the mount106. Each of the camera assembly102and the light assemblies104may be independently oriented (or otherwise repositioned). For example, to adjust an illumination area, the first light assembly104(1) and/or the second light assembly104(2) may pivot, rotate, and so forth. Additionally, the camera assembly102may rotate to adjust FoV of the camera110and/or motion sensor(s). In some instances, the camera assembly102and the light assemblies104are rotatable about multiple axes. Details of the coupling between the camera assembly102and the light assemblies104are discussed herein, however, such couplings may represent ball and socket joints, swivel joints, knuckle joints, universal joints, revolute joints, and so forth. Moreover, the coupling between the camera assembly102and the light assemblies104may be secured to lock the camera assembly102and the light assemblies104in place to maintain their respective orientation.

FIG.2illustrates a rear perspective view of the device100, according to examples of the present disclosure. The camera assembly102and the light assemblies104are shown coupled to, or extending from, the mount106. In some instances, the first light housing132(1) includes first heat dissipating elements200(1) (e.g., fins) and/or the second light housing132(2) includes second heat dissipating elements200(2) (e.g., fins) for dispersing heat generated by the lighting elements within the first light housing132(1) and the second light housing132(2), respectively.

The mount106may define a passageway204through which wires may route for providing power to the camera assembly102and the light assemblies104. However, other wires, cables, and the like may route through the passageway204(e.g., Ethernet). Additionally, in some instances, the device100may be battery powered. The mount106may include other holes206disposed through the mount106and which may be used to secure the mount106to the surface. For example, fasteners may be disposed through the holes206.

FIG.3illustrates a front view of the device100, according to examples of the present disclosure. In some instances, given that the device100may be configured to mount to a surface, the camera assembly102may be generally oriented downwards towards a ground surface to permit the device100to sense motion within the environment. However, the camera assembly102may be pivotable about one or more axes (e.g., X-axis, Y-axis, and/or Z-axis) to adjust a FoV of the sensor(s), whether the camera110, the motion sensor(s), and so forth. The camera assembly102further includes the housing126, the front cover124coupled to the housing126, and the sensor lens128coupled to the housing126and/or the front cover124.

The light assemblies104reside vertically above the camera assembly102. In some instances, the camera assembly102may be located centrally (e.g., in the X-direction) between the first light assembly104(1) and the second light assembly104(2). The light assemblies104may also be pivotable about one or more axes (e.g., X-axis, Y-axis, and/or Z-axis) to adjust a FoV of the lighting elements within the light assemblies104, respectively.

In some instances, the camera assembly102and/or the light assemblies104may be substantially square shaped (e.g., in the X-Y plane). However, other shapes are envisioned, and the camera assembly102and/or the light assemblies104may be coupled or otherwise mounted to the mount106differently than shown.

FIG.4illustrates a rear view of the device100, according to examples of the present disclosure. The mount106is configured to couple the device100to a surface, and wires are configured to extend through the passageway204for providing power, signals, or other data to the device100.

The camera assembly102includes orifices400disposed along the bottom118of the housing126. A speaker may reside beneath the orifices400(e.g., in the Y-direction) and may be oriented to emit sound towards the orifices400. When the speaker outputs sound, the orifices400may output sound downward and outward from the device100. Although the orifices400are shown being a certain size, shape, and number, the orifices400may be represented differently than shown. Additionally, the orifices400may be located on additional or alternative locations of the housing126(e.g., the first side120). A rear cover402is further shown coupled to the back114of the housing126. In some instances, the rear cover402may be omitted, and instead, the back114of the housing126may be enclosed.

FIG.5illustrates a top view of the device100, according to examples of the present disclosure. In some instances, the device100includes a bracket500that couples the first light housing132(1) and the second light housing132(2) to the mount106. For example, a first arm502(1) may couple to the first light housing132(1) and the bracket500, while a second arm502(2) may couple to the second light housing132(2) and the bracket500. In some instances, the first arm502(1) and the second arm502(2) are rotationally coupled to the bracket500(e.g., rotatable about the X-axis) for adjusting an orientation of the first light housing132(1) and the second light housing132(2). Additionally, the first light housing132(1) and the second light housing132(2) may be rotationally coupled to the first arm502(1) and the second arm502(2) (e.g., about the Y-axis).

In some instances, the rotational coupling between the first arm502(1) and the second arm502(2) with the bracket500may vertically adjust the first light housing132(1) and the second light housing132(2), respectively, up and down. In some instances, the rotational coupling between the first light housing132(1) and the first arm502(1), as well as the second light housing132(2) and the second arm502(2), respectively, may horizontally adjust the first light housing132(1) and the second light housing132(2) side to side. In some instances, the bracket500may additionally or alternatively be rotationally coupled to the mount106.

A line A-A is further shown extending through the second light housing132(2), which is used to illustrate a cross-sectional view of the second light housing132(2) inFIG.8.

FIG.6illustrates a bottom view of the device100, according to examples of the present disclosure. In some instances, the camera assembly102couples to the mount106via a ball and socket joint600. In some instances, the ball and socket joint600includes a ball602extending from the housing126(or the rear cover402) that is received within a socket604disposed on the mount106. The socket604may be configured to tighten and loosen around the ball602to permit the housing126to be reoriented. The housing126is further shown including the orifices400for outputting sound from the speaker.

FIGS.7A and7Billustrate side views of the device100, according to examples of the present disclosure.FIG.7Aillustrates a view of the first side120of the device100, whileFIG.7Billustrates a view of the second side122of the device100.

The first light housing132(1) couples to the bracket500via the first arm502(1) (as shown inFIG.7A), and the second light housing132(2) couples to the bracket500via the second arm502(2) (as shown inFIG.7B). The bracket500is received by, or coupled to, the mount106. Additionally, the camera assembly102couples to the mount106via the ball and socket joint600. In some instances, the ball602of the camera assembly102extends from the rear cover402, and the socket604extends from the mount106. The socket604is accordingly sized and shaped to receive the ball602.

In some instances, the first light assembly104(1), the second light assembly104(2), and the camera assembly102each have a degree of movement without contacting one another. For example, the first light assembly104(1) may be rotated downward, from the position shown inFIG.7A, without making contact with the camera assembly102(whether the camera assembly102is rotated upwards or not from the position of the camera assembly102shown inFIG.7A).

A line B-B is further shown inFIG.7A, which is used to illustrates a cross-sectional view of the device inFIG.17.

FIG.8illustrates a cross-sectional view of the second light assembly104(2), taken along line A-A ofFIG.5, according to examples of the present disclosure. Although the discussion ofFIG.8relates to the second light assembly104(2), it is to be understood that the first light assembly104(1) may include similar components, and function similar to the second light assembly104(2).

The second light assembly104(2) includes the second light housing132(2) and the second window130(2). Lighting elements are disposed within the second light housing132(2), beneath the second window130(2), and are configured to emit light through the second window130(2). The second arm502(2) couples to the bracket500for adjusting an orientation of the second arm502(2). Additionally, the second arm502(2) couples to the second light housing132(2) (or more generally, the second light assembly132(2)). As will be discussed herein, the second light assembly104(2) and the second arm502(2) may be adjoined via a ratchet mechanism800. The ratchet mechanism800may include teeth802disposed on the second arm502(2), and which engage with a coupler804disposed in the second light housing132(2). For example, the teeth802(or other serrations) may be engaged by the coupler804. The second light housing132(2) may rotate (e.g., about the Y-axis), and during which, the coupler804may drive along the teeth802. The engagement between the coupler804and the teeth802may secure the second light housing132(2) in place, however, upon application of a sufficient amount of force, the coupler804may engage with different teeth802during reorientation of the second light housing132(2). A fastener806may secure the coupler804to the second light housing132(2).

FIG.9illustrates an interior view of the second light assembly104(2), according to examples of the present disclosure. Although the discussion ofFIG.9relates to the second light assembly104(2), it is to be understood that the first light assembly104(1) may include similar components, and function similar to the second light assembly104(2).

InFIG.9, the second window130(2) is shown removed from the second light housing132(2). Lighting elements900are disposed beneath the second window130(2), within a cavity902of the second light housing132(2). In some instances, the lighting elements900are disposed on an LED PCB904. The second light assembly104(2) may include any number of the lighting elements900, which in some instances, may be arranged in a grid-like fashion. However, the lighting elements900may be arranged differently than shown, and/or more than or less than the number of the lighting elements900as shown may be included. In some instances, the lighting elements900may represent LEDs, OLEDs, and so forth. The second light assembly104(2) may also include a reflector906that directs light emitted from the lighting elements900out the second window130(2).

FIG.10illustrates an interior view of the second light assembly104(2), according to examples of the present disclosure. Although the discussion ofFIG.10relates to the second light assembly104(2), it is to be understood that the first light assembly104(1) may include similar components, and function similar to the second light assembly104(2).

InFIG.10, the second window130(2), the lighting elements900, and the reflector906are shown removed from the second light housing132(2). Removing the lighting elements900and the reflector906exposes the coupler804that engages with the teeth802disposed on an end of the second arm502(2). The coupler804couples to the second light housing132(2) via the fastener806. The coupler804includes a notch1000(e.g., tooth) that engages with the teeth802. As the second light housing132(2) is rotated, the notch1000may be driven over and along the teeth802. In some instances, within the cavity902, the coupler804may reside beside the second heat dissipating elements200(2).

FIG.11illustrates an interior view of the second light assembly104(2), according to examples of the present disclosure. Although the discussion ofFIG.11relates to the second light assembly104(2), it is to be understood that the first light assembly104(1) may include similar components, and function similar to the second light assembly104(2).

InFIG.11, the second window130(2), the lighting elements900, the reflector906, and the coupler804are shown removed from the second light housing132(2). Removing the coupler804exposes the teeth802of the ratchet mechanism800that engage with the coupler804, and more specifically, the notch1000of the coupler804. For example, the teeth802may annularly extend around a perimeter of an end of the second arm502(2). The end of the second arm502(2) may be coupled with, or disposed within, a receptacle1100defined by the second light housing132(2). In doing so, as the second light housing132(2) rotates (e.g., about the Y-axis), the notch1000may be driven along the teeth802. Although the teeth802are shown extending completely around the perimeter of the end of the second arm502(2), in some instances, the teeth802may extend around a portion of the perimeter. The second light housing132further defines a slot1102for receiving the fastener806.

FIG.12illustrates an interior view of the second light assembly104(2), according to examples of the present disclosure. Although the discussion ofFIG.12relates to the second light assembly104(2), it is to be understood that the first light assembly104(1) may include similar components, and function similar to the second light assembly104(2).

InFIG.12, the second window130(2), the lighting elements900, the reflector906, and the ratchet mechanism800(e.g., the coupler804and the teeth802) are shown removed from the second light housing132(2). Removing the ratchet mechanism800exposes the receptacle1100of the second light housing132(2). When coupled to the second light housing132(2), a portion of the second arm502(2) may be at least partially disposed with the receptacle1100.

FIGS.13A and13Billustrate the coupler804, according to examples of the present disclosure. In some instances,FIG.13Aillustrates a perspective view of the coupler804, andFIG.13Aillustrates a front view of the coupler804.

In some instances, the coupler804includes a body1300having a front1302and a back1304spaced apart from the front1302(e.g., in the Z-direction). The body1300may also include a top1306and a bottom1308spaced apart from the top1306(e.g., in the Y-direction). The body1300defines a channel1310through which the fastener806is disposed for coupling the coupler804to the second light housing132(2). As shown, the channel1310may extend through the body1300proximate to the top1306. The body1300also includes a first wing1312(1) and a second wing1312(2) that define a slot1314for receiving an end of the second arm502(2) having the teeth802. As shown, the first wing1312(1) and the second wing1312(2) may represent prongs, arms, or branches that extend from the body1300. The first wing1312(1) and the second wing1312(2) may engage along sides (e.g., sidewalls) of the second arm502(2) to retrain the second arm502(2) within the receptacle1100and the engage the notch1000of the coupler804with the teeth802. For example, a sidewall1316(or surface) of the slot1314may engage with an exterior surface of the second arm502(2). As shown, the slot1314may be half-circular shaped to correspond to a profile of the second arm502(2).

The body1300includes a crosspiece1318having the notch1000. The crosspiece1318may be capable of deflecting (e.g., in the Y-direction) as the notch1000traverse along the teeth802. For example, the body1300may include a first cavity1320disposed vertically above the crosspiece1318, and a second cavity1322disposed vertically below the crosspiece1318. The first cavity1320and the second cavity1322permit the crosspiece1318to deflect as the notch1000traverses along the teeth802. For example, when traversing along the teeth802(e.g., at a peak between adjacent teeth of the teeth802), the crosspiece1318may deflect in an upward manner, into the first cavity1320, and then may transition back once the notch1000resides between adjacent teeth802(e.g., a valley between the teeth802). As the notch1000traverses over the teeth802a user of the device100may be provided with tactile feedback. In some instances, the notch1000is aligned with the channel1310. The notch1000and the channel1310may also be centrally located between sides of the coupler804.

FIGS.14A and14Billustrate perspective views of the second arm502(2), according to examples of the present disclosure. Although the discussion ofFIGS.14A and14Brelates to the second arm502(2), it is to be understood that the first arm502(1) may include similar components, and function similar to the second arm502(2).

In some instances, the second arm502(2) includes a first end1400that couples to the bracket500and a second end1402that couples to the second light housing132(2). In some instances, the second arm502(2) may include a first segment1404and a second segment1406coupled to the first segment1404, vice versa. In some instances, the first segment1404forms a first side or first half of the second arm502(2), while the second segment1406may form a second side or second half of the second arm502(2). The first segment1404and the second segment1406may couple together via snap-fit connections, pressure fit connections, and/or fastener(s).

The first segment1404may include a post1408into which a fastener that is used to secure the first arm502(1) and the second arm502(2) to the bracket500is disposed. For example, the fastener may be threaded into the an opening of the post1408. As shown, the post1408may be disposed proximate to the first end1400of the second arm502(2). Additionally, the first segment1404may include a collar1410that engages with and/or resides within a channel of the bracket500. The collar1410may be annularly disposed around the post1408.

The second segment1406may include the teeth802that engage with the notch1000of the coupler804. Collectively, the coupler804and the teeth802may represent the ratchet mechanism800that couples the second light assembly104(2) to the second arm502(2) and the mount106. In some instances, the second end1402of the second arm502(2) includes a post, pillar, or column1412that extends from, or represents a portion of, the second arm502(2). In some instances, the column1412is substantially cylindrically shaped for residing within the receptacle1100of the second light housing132(2). The teeth802are disposed on an end, or are form within the end, of the column1412. Additionally, the column1412may define a groove1414. The groove1414may be sized to receive the first wing1312(1) and the second wing1312(2) of the coupler804. For example, the sidewall1316of the slot1314may engage with the column1412, within the groove1414. In some instances, the engagement between the first wing1312(1) and the second wing1312(2) with the groove1414may prevent the second light assembly104(2) separating (e.g., being pulled apart) from the second arm502(2).

The second arm502(2) defines a cavity1416through which wires or other cables are routed into the second light housing132(2). As shown, the teeth802are radially disposed around the cavity1416. The wires or other cables may be routed into the second arm502(2) at the first end1400, and through an interior of second arm502(2) formed by the first segment1404and the second segment1406. Therein, the wires or other cables may exit the cavity1416at the second end1402, and into the second light housing132(2). In turn, the wires or other cables may be coupled to the LED PCB904. Such coupling, for example, may provide power to the lighting elements900, as well as signals that control an operation of the light elements900(e.g., turn on in response to motion being detected).

FIG.15illustrates an engagement between the coupler804and the teeth802of the ratchet mechanism800, according to examples of the present disclosure. Although the discussion ofFIG.15relates to the second arm502(2), it is to be understood that the first arm502(1) may include similar components, and function similar to the second arm502(2).

As introduced above inFIGS.14A and14B, the teeth802are disposed on the second arm502(2) and engage with the coupler804coupled to the second light housing132(2). InFIG.15, the second light housing132(2) is shown removed to illustrate the engagement between the teeth802and the coupler804. As shown, the notch1000of the coupler804engages with the teeth802. Moreover, the first wing1312(1) (obscured inFIG.15) and the second wing1312(2) engage with the groove1414to secure the second light housing132(2) to the second arm502(2). During rotation of the second light housing132(2) (e.g., about the Y-axis), for example, to change an orientation of the second light assembly104(2), the notch1000of the coupler804may traverse in between adjacent teeth of the teeth802. The cavity1416is provided for routing cables or other wires up and into the second light housing132(2). As shown, the teeth802may be disposed around the cavity1416.

FIG.16illustrates a perspective view of the bracket500, according to examples of the present disclosure. The bracket500is configured to receive the first arm502(1) and the second arm502(2). For example, the bracket500may include a first end1600that couples to the mount106, and an opposite second end1602that receives the first arm502(1) and the second arm502(2). More specifically, the second end1602may include a channel1604that extends through a thickness of the bracket500(e.g., in the X-direction). The collar1410of the second arm502(2), as well as a collar of the first arm502(1) (similar to the collar1410of the second arm502(2)), may be insertable into the channel1604. The first arm502(1) and the second arm502(2) may be rotatable within the channel1604. As will be explained herein, a fastener may be disposed through the first arm502(1) and the second arm502(2) for coupling the first arm502(1) and the second arm502(2) to the bracket500. In some instances, the first end1600of the bracket500may be fastened to the mount106, or the bracket500may be threaded into the mount106. In some instances, the first end1600of the bracket500may be rotatable within the mount106to adjust an orientation of the bracket500, and consequently, the light assemblies104. In some instances, threads1606are disposed proximate to the first end1600and are threaded into a receptacle of the mount106. The threads1606permit the bracket500to rotate within the receptacle of the mount106while still being coupled thereto.

Additionally, in some instances, wires or other cables may route through the bracket500. For example, the mount106may include one or more PCBs that supply power to the light assemblies104. The one or more PCBs may also communicatively couple the camera assembly102to the light assemblies104, respectively, such as controlling the lighting elements900in response to motion being detected. In some instances, the wires or other cables may route through a body of the bracket500, between the first end1600and the second end1602. In such instances, the wires or other cables may be routed through the channel1604and into the first arm502(1) and the second arm502(2), respectively.

FIG.17illustrates a cross-sectional view of the device100, taken along line B-B ofFIG.7A, showing an engagement between the first arm502(1), the second arm502(2), and the bracket500, according to examples of the present disclosure. The first arm502(1) and the second arm502(2) engage within the channel1604of the bracket500. For example, the collar1410of the first arm502(1) and the second arm502(2) reside within the channel1604of the bracket500.

Further, a fastener1700may be used to secure the first arm502(1) and the second arm502(2) to the bracket500. For example, the fastener1700may be disposed through the post1408of the second arm502(2), and engaged with a threaded receptacle1702. Tightening the fastener1700may create a friction fit between the first arm502(1), the second arm502(2), and the bracket500. In some instances, the fastener1700is insertable into the first arm502(1) via a passageway1704. Once the fastener1700is tightened, a plug1706may be disposed within the passageway1704to enclose and seal the passageway1704. In some instances, the fastener1700may be loosened to adjust an orientation of the first arm502(1) and/or the second arm502(2) (e.g., rotate about the X-axis), and may be tightened to secure the first arm502(1) and/or the second arm502(2) in place.

A first passageway1708(1) is formed to route wires or other cables from the mount106, through the bracket500, and into the first arm502(1). Likewise, a second passageway1708(2) is formed to route wires or other cables from the mount106, through the bracket500, and into the second arm502(2). The first arm502(1) and the second arm502(2) may include respective cavities through which the wires or other cables are respective routed into the first light assembly104(1) and the second light assembly104(2).

In some instances, various seals (e.g., O-rings, gaskets, etc.) may be disposed between the bracket500, the first arm502(1), and the second arm502(2). The seals may prevent the ingress of debris, liquid, and so forth into the bracket500, the first arm502(1), and the second arm502(2).

FIG.18illustrates the second arm502(2), showing the plug1706engaged within the passageway1704, according to examples of the present disclosure. Removing the plug1706exposes the fastener1700and allows the fastener1700to be loosened and tightening for adjusting an orientation of the first arm502(1) and/or the second arm502(2), and consequently, the first light assembly104(1) and/or the second light assembly104(2), respectively.

FIG.19illustrates a front view of the camera assembly102of the device100, according to examples of the present disclosure. As introduced above, the camera assembly102includes the front cover124and the housing126, as well as the top116, the bottom118, the first side120, the second side122, the front112, and the back114.

The front cover124may include a first channel1900, a second channel1902, and a third channel1904. The first channel1900may direct sound to a microphone disposed within the camera assembly102. For example, the first channel1900may represent a microphone port that channels sound to a microphone disposed within the camera assembly102. The second channel1902and/or the third channel1904may output light associated with an operational state of the device100(e.g., recording audio, outputting sound, recording image/video data, detecting motion, etc.). Lighting elements of the camera assembly102, for example, may be configured to emit light out of the second channel1902and the third channel1904, respectively. In some instances, a first lighting element disposed beneath the second channel1902may output light associated with one or more first operations being performed by the device100(e.g., recording audio, recording video, etc.), while a second lighting element disposed beneath the third channel1904may output light associated with one or more second operations being performed by the device100(e.g., detected motion).

The camera assembly102may also include a camera lens1906coupled to or disposed within the front cover124. The camera110of the device100is disposed behind (e.g., Z-direction) the camera lens1906for imaging an environment of the device100. The camera assembly102also includes the button108, which may be used to at least partially control an operation of the device. In some instances, the camera lens1906is located centrally between the first side120and the second side122, and/or may be located more proximate to the top116than the bottom118. In some instances, the first channel1900is located more proximate to the top116than the bottom118, and may be located more proximate to the first side120than the second side122. Additionally, the button108may be located centrally between the first side120and the second side122. In some instances, the second channel1902is located to a first side of the camera110(or the camera lens1906) and may be located more proximate to the first side120and/or the top116, while the third channel1904is located to a second side of the camera110(or the camera lens1906) and may be located more proximate to the second side122and/or the top116.

In some instances, the front cover124and/or the sensor lens128are transmissive to signals and/or light rays. For example, in some instances, IR sensor(s) may reside beneath the front cover124and are oriented to emit IR signals in front of the device100for detecting motion. In such instances, the IR sensor(s) may output IR light through the front cover124, and receive IR light reflected off object(s) in the environment. Additionally, PIR sensor(s) may reside beneath the sensor lens128and are configured to receive IR (e.g., radiation) emitted from sources (e.g., people, animals, etc.). In some instances, the front cover124and the sensor lens128are manufactured from different materials, or the same materials. Example materials include, for example, from high-density polyethylene (HDPE), silicon, germanium, zinc-sulfide, or zinc-selenide, and so forth.

FIG.20illustrates example computing components residing within the camera assembly102, according to examples of the present disclosure. InFIG.20, the front cover124and the sensor lens128are shown removed from the housing126.

In some instances, the camera assembly102includes a first PCB2000and a second PCB2002. The first PCB2000may be disposed in front of (e.g., more proximate to the front112) the second PCB2002. Among other components, the first PCB2000may include a first IR sensor2004(1) (e.g., IR LED), a second IR sensor2004(2) (e.g., IR LED), an ambient light sensor2006, a first light guide2008, and a second light guide2010. The first IR sensor2004(1) and the second IR sensor2004(2) are configured to emit IR light through the front cover124and into the environment. The ambient light sensor2006receives light through the front cover124. The ambient light sensor2006is configured to generate data indicative of a brightness of the environment (e.g., for switching between nighttime and daytime modes).

The first light guide2008may output light from a lighting element disposed beneath (e.g., in the Z-direction) the first light guide2008. The first light guide2008is configured to direct light out the second channel1902. Similarly, the second light guide2010may output light from a lighting element disposed beneath (e.g., in the Z-direction) the second light guide2010. The second light guide2010is configured to direct light out the third channel1904. In some instances, the first light guide2008and/or the second light guide2010may output light indicative of an operational status and/or setup of the device100and/or the camera assembly102. For example, the first light guide2008may output light indicative of an operational status of the device100, which the second light guide2010may output light during a setup of the device100(e.g., syncing, connecting, etc.).

The camera110may be mounted to the second PCB2002and at least partially disposed through an opening in the second PCB2002. For example, the camera110may be mounted to the second PCB2002, and a body of the camera110may be disposed through an opening of the first PCB2000. Here, the camera110may include a first end coupled to the second PCB2002and second end disposed in front of the first PCB2000(e.g., spaced apart in the Z-direction). A portion of a body of the camera110, between the first end and the second end, is disposed through the first PCB2000. Accordingly, the first PCB2000includes a passageway through which the body of the camera110is disposed.

Additionally, the second PCB2002may include a first PIR sensor2012(1) and a second PIR sensor2012(2). The first PIR sensor2012(1) and the second PIR sensor2012(2) are shown being in a vertically stacked relationship on the second PCB2002. For example, the first PIR sensor2012(1) may be located more proximate to the top116of the housing126than the second PIR sensor2012(2). The first PIR sensor2012(1) and the second PIR sensor2012(2) are arranged to receive light rays through the sensor lens128.

In some instances, the first PIR sensor2012(1) and the second PIR sensor2012(2) may include, for example, two pyroelectric sensing elements and each pyroelectric sensing element may have a pyroelectric crystal. The pyroelectric sensing elements may generate an electrical charge in response to heat. Radiation (e.g., IR light) received at a surface of a pyroelectric sensing element generates heat, which in turn, generates an electrical charge sensed by the first PIR sensor2012(1) and the second PIR sensor2012(2), respectively. Stated alternatively, an absorbing layer of a pyroelectric sensing element transforms radiation flux change into a change in temperature and a pyroelectric component performs a thermal to electrical conversion. One or more low-noise and low leakage current field-effect transistors (e.g. JFET) or operational amplifiers are used to convert charge into a signal voltage.

In some instances, the two pyroelectric sensing elements of the first PIR sensor2012(1) and the second PIR sensor2012(2) may be electrically coupled together with opposite polarization to produce an output. In this way, an equal change in temperature at both of the pyroelectric sensing elements will cancel out in the output signal, thus filtering out temperature changes in the environment. However, a change in temperature at only one of the pyroelectric sensing elements of the first PIR sensor2012(1) and the second PIR sensor2012(2) will result in an output signal that is positive or negative (depending on which pyroelectric sensing element experienced the change in temperature).

In some instances, the first PIR sensor2012(1) and the second PIR sensor2012(2) may include two slots, each providing an optical path to one of the pyroelectric sensing elements. A Fresnel lens formed by or within a portion of the sensor lens128is configured to direct light onto the pyroelectric sensing elements. In some instances, such as in the case that the device100includes two PIR sensors, the Fresnel lens array is configured to direct light received at a first portion of the sensor lens128(e.g., upper half) onto the pyroelectric sensing elements of the first PIR sensor2012(1) and to direct light received at a second portion of the sensor lens128(e.g., lower half) onto the pyroelectric sensing elements of the second PIR sensor2012(2). The first PIR sensor2012(1) and the second PIR sensor2012(2) may be analog, with an analog signal output, or may be digital, with digital data output generated utilizing an analog-to-digital converter (ADC).

In some instances, the device100may include the first PIR sensor2012(1) and the second PIR sensor2012(2) to detect objects. For example, the first PIR sensor2012(1) and the second PIR sensor2012(2) may output a signal or sensor data, where the device100uses a characteristic determined using the signal or sensor data to determine whether the first PIR sensor2012(1) and/or the second PIR sensor2012(2) detected an object. The characteristic may include a voltage represented by the signal or sensor data, an amplitude of a wave generated or determined using the signal or sensor data, an angle of the wave generated using the signal or sensor data, and/or the like.

In some instances, an interior surface of the sensor lens128includes the Fresnel lens that directs light to the first PIR sensor2012(1) and the second PIR sensor2012(2), respectively. The Fresnel lens may be made up of a plurality of individual lens elements having concentric grooves, such as the facets and translation edges, that form an Fresnel lens array. For example, the concentric grooves may be etched, milled, cut, molded, or otherwise formed within a rearward surface oriented towards the first PIR sensor2012(1) and the second PIR sensor2012(2). The Fresnel lens may increase a FoV of the first PIR sensor2012(1) and the second PIR sensor2012(2) for detecting motion within the environment. An example Fresnel lens array is described in, for example, U.S. patent application Ser. No. 17/990,200, filed Nov. 18, 2022, entitled “Fresnel Lens with Variable-Angle Translation Edges.” This patent application, as well as any publications thereof or patents issuing therefrom, are herein incorporated by reference.

The camera assembly102may further include a microphone assembly2014. The microphone assembly2014may be mounted to the front cover124, and communicatively coupled to the first PCB2000and/or the second PCB2002. A portion of the microphone assembly2014is aligned with the first channel1900such that sound may be directed to a microphone of the microphone assembly2014. Various shielding or isolating foams may be disposed around the microphone assembly2014, the front cover124, the sensor lens128, and so forth for acoustically sealing the microphone, and/or to prevent the ingress of liquid or other debris into the camera assembly102.

In some instances, the camera110includes a substantially similar FoV as the PIR sensor(s)2012. For example, the PIR sensor(s)2012detect motion within a FoV, and the camera110may have a FoV that is the same as, or substantially overlaps with the PIR sensor(s)2012. That is, the first PIR sensor2012(1) and the second PIR sensor2012(2) may have a collective FoV, and the camera110has a FoV that aligns with the collective FoV of the first PIR sensor2012(1) and the second PIR sensor2012(2). In doing so, as the first PIR sensor2012(1) and/or the second PIR sensor2012(2) sense motion, the camera110is able to capture image data and/or video data associated with the motion. Additionally, a FoV of the light assemblies104may overlap with the FoV of the camera110such that the light assemblies illuminate the image data and/or video data captured by the camera110.

A line C-C is further shown extending through the camera assembly102, which is used to illustrate a cross-sectional view of the sensor subassembly inFIG.21.

FIG.21illustrates a cross-sectional view of the camera assembly102, taken along line C-C ofFIG.20, according to examples of the present disclosure.

The camera assembly102includes the first PCB2000, the second PCB2002, the camera110, the button108, the first PIR sensor2012(1), and the second PIR sensor2012(2). The camera110, the button108, the first PIR sensor2012(1), and the second PIR sensor2012(2) may be mounted or coupled to the second PCB2002. As shown, the camera110may be coupled to the second PCB2002, but may extend through an opening of the first PCB2000. The button108is further shown being at least partially disposed through the housing126. While a single button is shown, the device100may include additional buttons. In some instances, the button108may correspond to a power button, a wireless connectivity button, a mute button, volume buttons, a reset button, sync buttons, or any other type of button or control. The button108may also be located on sides of the housing126other than the top116. In some instances, the button108may be mechanical (e.g., having physically movable components) and/or electronic (e.g., capacitive sensors, optical sensors, touch screen, or the like). In some instances, the button108may be located closer to the front112than the back114(e.g., spaced apart in the Z-direction).

The camera assembly102further includes a speaker2100oriented to emit sound through the orifices400of the housing126. As shown, the speaker2100is oriented towards the bottom118of the camera assembly102. The speaker2100may be disposed within a speaker housing2102that provides a back volume to the speaker2100. The speaker2100may represent a tweeter speaker, a mid-range speaker, or a subwoofer speaker.

A connection2104of the camera assembly102may receive wires or other cables that are routed into the housing126. The connection2104may couple to the ball602of the ball and socket joint600.

FIGS.22A-22Cillustrate various components of the camera assembly102, according to examples of the present disclosure.FIG.22Aillustrates a perspective view of the first side120of the camera assembly102,FIG.22Billustrates a perspective view of the second side122of the camera assembly102, andFIG.23illustrates a planar view of the second side122of the camera assembly102.

The first IR sensor2004(1), the second IR sensor2004(2), the first light guide2008, and the second light guide2010may be disposed on the first PCB2000. Additionally, the ambient light sensor2006may be disposed on the first PCB2000. The camera110, the first PIR sensor2012(1), and the second PIR sensor2012(2) may be disposed on the second PCB2002. In some instances, the first PCB2000and the second PCB2002communicatively couple to one another via a pin and socket connector2200. For example, the first PCB2000may include a pin connector that are received within sockets of the second PCB2002.

The first IR sensor2004(1), the second IR sensor2004(2), the ambient light sensor2006, the first light guide2008, and the second light guide2010are shown being disposed on a first side of the first PCB2000and oriented in a first direction (e.g., towards the front112). Additionally, the camera110, the first PIR sensor2012(1), and the second PIR sensor2012(2) may be disposed on a first side of the second PCB2002and oriented in the first direction (e.g., towards the front112). The speaker2100may be oriented in a second direction that is different from the first direction (e.g., towards the bottom118). The button108may be oriented in a third direction that is opposite the second direction (e.g., towards the top116). In some instances, the button108mounts to the second PCB2002, at a second side that is opposite to the first side in which the camera110, the first PIR sensor2012(1), and the second PIR sensor2012(2) are disposed.

The microphone assembly2014may be coupled to or disposed on the first PCB2000. In some instances, the microphone assembly2014is disposed in front of the second PCB2002. In some instances, the microphone assembly2014may include a microphone PCB having a microphone mounted thereto. In some instances, a flexible printed circuit (FPC)2202communicatively couples the microphone PCB to the second PCB2002. Additional details of the microphone assembly2014are described in, for example, U.S. patent application Ser. No. 18/074,098, filed Dec. 2, 2022, entitled “Audio/Visual (A/V) Device.” This patent application, as well as any publications thereof or patents issuing therefrom, are herein incorporated by reference.

In some instances, when the camera assembly102is assembled, the first PCB2000may couple to the front cover124. The second PCB2002, in some instances, may couple to the rear cover402. Additionally, or alternatively, the first PCB2000and/or the second PCB2002may couple to the speaker housing2102and/or the housing126.

The ball602of the camera assembly102is shown including wires2204extending therethrough. That is, the wires2204may route through the ball and socket joint600for transferring power, signals, data, and the like to the camera assembly102. Such signals or data, for example, may control an operation of the lighting elements900within the light assemblies104. In some instances, the wires2204are connected to the second PCB2002. In some instances, the wires2204connect to other wires within the mount106. For example, within the mount, the wires2204may connect with wires providing power to the device100. Although not shown, wire, or other cables, may route from the camera assembly102to the light assemblies104, for example, or the power may split within the mount106to provide power to the camera assembly102and the light assemblies104, respectively. However, the camera assembly102and the light assemblies104may be communicatively coupled to one another, for example, to at least partially control an operation thereof. For example, in response to detecting motion within the environment, the light assemblies104may illuminate.

The first PCB2000and/or the second PCB2002may include various cutouts for aligning the first PCB2000and/or the second PCB2002within the housing126, vice versa. For example, the cutouts may engage with protrusions, flanges, and so forth within the housing126. Additionally, or alternatively, channels may be disposed through the first PCB2000and/or the second PCB2002, and fasteners may be disposed through the channels and received within posts of the housing126to couple the first PCB2000and/or the second PCB2002to the housing126.

FIGS.23A and23Billustrate various components of the camera assembly102, according to examples of the present disclosure.FIG.23Aillustrates a front view of the camera assembly102, andFIG.23Billustrates a rear perspective view of the camera assembly102. InFIGS.23A and23B, the first light guide2008, the second light guide2010, the button108, and portions of the microphone assembly2014are shown removed.

A first lighting element2300and a second lighting element2302are disposed on the first PCB2000. The first lighting element2300may output light through the second channel1902in the front cover124via the first light guide2008, while the second lighting element2302may output light through the third channel1904in the front cover124via the second light guide2010. In some instances, the first lighting element2300and the second lighting element2302may output light indicative of operations being performed by the device100. For example, the first lighting element2300may output light in response to first operations of the device100, such as recording video, while the second lighting element2302may output light in response to second operations of the device100, such as detecting motion, syncing with other devices, setup, and so forth. In some instances, the first lighting element2300may be an RGB lighting element, and the second lighting element2302may be a blue lighting element.

In some instances, the microphone assembly2014includes a microphone PCB2304. The microphone PCB2304may be encased, or otherwise at least partially enclosed, via a microphone seal (shown removed inFIGS.23A and23B). The microphone PCB2304may be coupled to the second PCB2002via the FPC2202. Additionally, a microphone2306may mount to the microphone PCB2304, and a channel of the microphone PCB2304may route sound to the microphone2306.

In some instances, the camera110is vertically aligned with the first PIR sensor2012(1) and the second PIR sensor2012(2). Additionally, or alternatively, the camera110may be horizontally aligned with the first IR sensor2004(1), the second IR sensor2004(2), the first lighting element2300, and/or the second lighting element2302.

The camera assembly102, or more generally, the device100, may include additional computing components not described. For example, the camera assembly102may include processors, memory, circuits, transformers, power supplies, network interfaces (e.g., Wi-Fi, Bluetooth, ZigBee, LTE, Bluetooth Low Energy (BLE), thermal pads, shielding foams, shielding plates, and so forth. In some instances, these computing components may be disposed on the first PCB2000and/or the second PCB2002. Various connectors (e.g., flex circuits) may communicatively couple such components together.

FIGS.24A and24Billustrate the housing126of the camera assembly102, according to examples of the present disclosure.FIG.24Aillustrates a front perspective view of the housing126, andFIG.24Billustrates a rear perspective view of the housing126.

The housing126defines a cavity2400in which components of the camera assembly102are disposed. For example, the first PCB2000, the second PCB2002, the speaker housing2102, and so forth may be disposed within the cavity2400. In some instances, the cavity2400may include various posts2402to which components of the camera assembly102are coupled to. For example, the first PCB2000and the second PCB2002may be secured to the posts2402via fastener(s). The housing126may further define the orifices400for the speaker2100. A receptacle2404may receive at least a portion of the button108.

The front cover124may couple to the housing126, for example, at a front of the housing126(or the front112of the camera assembly102). In some instances, the ball602and/or the connection2104may couple to the housing126within a recess2406at the back114.

FIG.25AandFIG.25Billustrate the front cover124, according to examples of the present disclosure.FIG.25Aillustrates a front perspective view of the front cover124, andFIG.25Billustrates a rear perspective view of the front cover124.

The front cover124defines the first channel1900, the second channel1902, and the third channel1904. Additionally, the front cover124defines a fourth channel2500through which at least a portion of the camera110is disposed. Additionally, the camera lens1906may be disposed in the fourth channel2500. The front cover124may also define a divider2502. The first PIR sensor2012(1) may be arranged vertically above the divider2502, and the second PIR sensor2012(2) may be arranged vertically below the divider2502. In doing so, first light rays may be directed to the first PIR sensor2012(1) and second light rays may be directed to the second PIR sensor2012(2). In some instances, the front cover124defines a window2504through which the first PIR sensor2012(1) and the second PIR sensor2012(2) are configured to receive light rays. The divider2502may extend across a portion of the window2504, so as to adjoin adjacent sidewalls of the window2504.

In some instances, the window800has an upper portion2506and a lower portion2508. The first PIR sensor2012(1) is arranged to receive light rays via the upper portion2506, while the second PIR sensor2012(2) is arranged to receive light rays via the lower portion2508. In some instances, the upper portion2506is larger in size than the lower portion2508. In some instances, surfaces of the divider2502are scalloped-shaped. The scalloped-shaped surface of the divider2502may reduce glare of incoming light rays being received by the first PIR sensor2012(1) and/or the second PIR sensor2012(2), respectively.

The front cover124may include first attachment mechanisms2510that engage or correspond to second attachment mechanisms of the sensor lens128. The first attachment mechanisms2510may represent flanges, slots, tabs, keyways, and the like that engage with corresponding features on the sensor lens128. Such engagement may secure the sensor lens128and the front cover124together. For example, the first attachment mechanisms2510and the second attachment mechanisms may snap together, slide together, press fit together, and so forth. The first attachment mechanisms2510may be disposed around at least a portion of a perimeter or periphery of the front cover124. In some instances, adhesives or fasteners may also be used to secure the front cover124and the sensor lens128together.

The front cover124includes an interior surface2512disposed at the back of the front cover124. The interior surface2512may define prongs that engage with features of the first PCB2000, the second PCB2002, the housing126, the microphone assembly2014, and so forth for aligning the first PCB2000, the second PCB2002, the housing126, the microphone assembly2014, and so forth within the camera assembly102. The interior surface2512may also define various other tabs, receptacles, slots, etc. for receiving components of the camera assembly102.

As discussed above, the first IR sensor2004(1) and the second IR sensor2004(2) are configured to output light through the front cover124. For example, the first IR sensor2004(1) and the second IR sensor2004(2) may emit signals (e.g., IR signals) through at least a portion of the front cover124and receive the signals to detect IR radiation. As such, at least a portion of the front cover124is transmissive to signals emitted from, and received by, the first IR sensor2004(1) and the second IR sensor2004(2).

In some instances, seals gaskets, and so forth may be interposed between the front cover124and the housing126to environmentally seal the camera assembly102.

FIG.26illustrates a FoV2600of the PIR sensor(s)2012of the device100, according to examples of the present disclosure. In some instances, the FoV2600may be representative of a collective FoV of the first PIR sensor2012(1) and the second PIR sensor2012(2). The FoV2600, however, may be formed via a first FoV2602of the first PIR sensor2012(1), a second FoV2604of the second PIR sensor2012(2), and a third FoV2606of the second PIR sensor2012(2). As shown, the first FoV2602may represent a FoV located furthest from the device100, while the third FoV2606may be located closest to the device100. The second FoV2604may be disposed between the first FoV2602and the third FoV2606.

The first FoV2602is made up by, or includes, a plurality of first detectable zones2608. The second FoV2604is made up by, or includes, a plurality of second detectable zones2610, and the third FoV2606is made up by, or includes, a plurality of third detectable zones2612. As shown, the plurality of first detectable zones2608, the plurality of second detectable zones2610, and the plurality of third detectable zones2612may be separated by first gaps2614, second gaps2616, and third gaps2618, respectively. That is, the first gaps2614may be interposed between adjacent detectable zones of the plurality of first detectable zones2608, the second gaps2616may be interposed between adjacent detectable zones of the plurality of second detectable zones2610, and the third gaps2618may be interposed between adjacent detectable zones of the plurality of second detectable zones2610.

The plurality of first detectable zones2608, the plurality of second detectable zones2610, and the plurality of third detectable zones2612may represent polarized areas, sections, or regions. For example, the plurality of first detectable zones2608represent polarized (e.g., + and −) zones of the PIR sensors2012that generate a signal as to whether a person (or other object) is leaving an individual zone of the plurality of first detectable zones2608. When the person is within a first gap of the first gaps2614, being as the person may not be within any of the plurality of first detectable zones2608, the first PIR sensor2012(1) may not detect the person. However, as a person comes within individual zones of the plurality of first detectable zones2608, for example, the one of the pyroelectric sensing elements of the first PIR sensor2012(1) generates a signal indicative of IR radiation emitted by the person. Such signals indicate whether the person is entering, or leaving, the detectable zones of the plurality of first detectable zones2608.

As will be explained further herein, the plurality of first detectable zones2608may be offset from the plurality of second detectable zones2610and/or the plurality of third detectable zones2612. Such offset prevents the signals generated by the first PIR sensor2012(1) and/or the second PIR sensor2012(2) cancelling out. For example, if the person enters two detection zones at the same time, the signals may be cancelled out and motion may not be detected by the device100. That is, a pyroelectric sensing element of the first PIR sensor2012(1) may receive radiation from a detection zone of the plurality of first detectable zones2608may generate a positive (+) signal, while a pyroelectric sensing element of the second PIR sensor2012(2) may receive radiation from a detection zone of the plurality of second detectable zones2610may generate a negative (−) signal. These signals may cancel out and the device100may fail to detect motion.

However, by offsetting the detection zones of the plurality of first detectable zones2608from the plurality of second detectable zones2610and the third detectable zones2612, the device100may more detect motion as an object, such as a person, approaches the device100. That is, the signals may not cancel out one another, thereby permitting the device100to sense motion. Take, for example, a person who approaches the device100along a first path2620. As the person approaches the device100, the person is detected upon entering one of the plurality of first detectable zones2608. As the person continues to walk towards the device100, along the first path2620, the person exits the detectable zone of the plurality of first detectable zones2608. The first path2620is shown being between the plurality of second detectable zones2610, such as within the second gaps2616. However, prior to this point, motion was detected and the camera110may have already begun capturing image and/or video data (e.g., upon entering one of the plurality of first detectable zones2608).

Additionally, a person who approaches the device100along a second path2622is not detected until reaching the plurality of second detectable zones2610. That is, the second path2622may be within one of the first gaps2614. However, motion is detected upon the person entering one of the plurality of second detectable zones2610if the person continues on the second path2622.

Comparatively, if all of the detectable zones were aligned, signals generated from the first PIR sensor2012(1) and the second PIR sensor2012(2) may overlap. For example, if the detectable zones of the plurality of first detectable zones2608and the plurality of second detectable zones2610were aligned, a pyroelectric sensing element that generates a first signal for one of the detectable zones of the plurality of first detectable zones2608may cancel out with a signal generated from a pyroelectric sensing element of the plurality of second detectable zones2610monitoring one of the detectable zones of the plurality of second detectable zones2610. As a result, motion may not be detected.

In some instances, the first FoV2602may be associated with a first tier of the FoV2600, while the second FoV2604and the third FoV2606may be associated with a second tier of the FoV2600. The first tier may be located more distant from the device100than the second tier. In some instances, a user of the device100may configure the device100to one monitor proximate to the device100and/or distant from the device100. In the former, the user may disable the second PIR sensor2012(1) and in the latter, the user may disable the first PIR sensor2012(1).

The plurality of first detectable zones2608, the plurality of second detectable zones2610, and the plurality of third detectable zones2612may be generated at least in part by a Fresnel lens of the device100. For example, the Fresnel lens may guide light from respective zones of the plurality of first detectable zones2608, the plurality of second detectable zones2610, and the plurality of third detectable zones2612to the first PIR sensor2012(1) and/or the second PIR sensor2012(2), respectively. In some instances, the Fresnel lens may include a plurality of individual lens elements having concentric grooves with different certain points and/or focal lengths for generating the plurality of first detectable zones2608, the plurality of second detectable zones2610, and the plurality of third detectable zones2612.

In response to sensing motion and/or the distance to the object, the device100may perform one or more processes. For a first example, the device100may be configured to send motion alerts and/or generate image data when objects are located within a threshold distance to the device100. As such, if the device100determines that a distance to an object is within the threshold distance, then the device100may send a motion alert and/or generate image data. However, if the device100determines that a distance to an object is outside of the threshold distance, then the device100may refrain from sending a motion alert and/or generate image data. For a second example, the device100may be configured to send motion alerts and/or generate image data when objects are moving towards the device100. As such, if the device100determines that an object is moving towards the device100using two distances, then the device100may send a motion alert and/or generate image data. However, if the device100determines that an object is moving away from the device100using two distances, then the device100may refrain from sending a motion alert and/or generate image data.

It will be appreciated that the illustrations with respect to the first FoV2602, the second FoV2604, and the third FoV2606are exemplary. In some instances, the device100may be configured to define different FoVs for the first PIR sensor2012(1) and/or the second PIR sensor2012(2) than those illustrated. In such instances, the detectable zones of the FoVs may be different than, or similar to, those illustrated. However, one or more of the detectable zones of the FoVs may be offset from other detectable zones of the FoVs to sense objects approaching the device100. Additional details of FoV for PIR sensors are described in, for example, U.S. patent application Ser. No. 17/855,752, filed Jun. 30, 2022, entitled “Techniques for Determining Distances Using Passive Infrared Sensors.” This patent application, as well as any publications thereof or patents issuing therefrom, are herein incorporated by reference.

FIG.27illustrates a cross-sectional view of the FoV2600of the device100, according to examples of the present disclosure. The cross-sectional view illustrates certain detectable zones of the plurality of first detectable zones2608, the plurality of second detectable zones2610, and the plurality of third detectable zones2612. For example, four of the plurality of first detectable zones2608, the plurality of second detectable zones2610, and the plurality of third detectable zones2612are shown.

As shown, the plurality of first detectable zones2608may be offset from the plurality of second detectable zones2610and the plurality of third detectable zones2612. For example, the plurality of first detectable zones2608may include an offset2700from the plurality of second detectable zones2610and the plurality of third detectable zones2612. The offset2700may represent a horizontal offset. By offsetting the plurality of first detectable zones2608, the device100is able to sense motion in instances where both the first PIR sensor2012(1) and the second PIR sensor2012(2) generate sensor data for detectable zones of the first FoV2602, the second FoV2604, and the third FoV2606.

FIG.28illustrates different tiers of the FoV2600of the device100, according to examples of the present disclosure. The first PIR sensor2012(1) may be associated with a first tier2800, while the second PIR sensor2012(2) may be associated with a second tier2802. In some instances, the different tiers may assist the device100in controlling detection distance range (e.g., distance of object to the device100).

As shown the first tier2800may encompass, or be associated with, the first FoV2602and/or the plurality of first detectable zones2608. The second tier2802may encompass, or be associated with, the second FoV2604and/or the plurality of second detectable zones2610, as well as the third FoV2606and/or the plurality of third detectable zones2612. The first PIR sensor2012(1) is configured to generate signals associated with the first tier2800, while the second PIR sensor2012(2) is configured to generate signals associated with the second tier2802. A dashed line2804exists between the first tier2800and the second tier2802, and may indicate a line of separation between the first tier2800and the second tier2802. By separating the first FoV2602, the second FoV2604, and the third FoV2606into tiers, the device100may more accurately detect a distance between an object and the device100. For example, the distance to the object may be determined by ignoring one of the signals generated from first PIR sensor2012(1) or the second PIR sensor2012(2) (e.g., nuisance detection).

The first PIR sensor2012(1) may include the first FoV2602that extends a first distance from the device100. The second PIR sensor2012(2) may include a second FoV that extends a second, shorter distance from the device100, and the third FoV2606that extends a third, even shorter distance from the device100. The distances and the FoV of the first PIR sensor2012(1) and the second PIR sensor2012(2) may be created based on an orientation of the first PIR sensor2012(1) and the second PIR sensor2012(2) on the device100, as well as the Fresnel lens (e.g., of the sensor lens128).

In some instances, the PIR sensors have non-overlapping FoVs. For example, the first FoV2602, the second FoV2604, and the third FoV2606may be non-overlapping. In such examples, the PIR sensors2012are able to detect objects when the objects are located close to the device100and when the objects are located far from the device100. For example, when the person is located at a first, closer location from the device100, the second PIR sensor2012(2) is able to detect the person while the first PIR sensor2012(1) may not detect the person. Based on this, the device100may determine that the person is within a first distance from the device100. In some instances, to make this determination, the device100may determine that a first value associated with the second PIR sensor2012(2) is large while a second value associated with the first PIR sensor2012(1) is zero or small. As such, the device100may determine that the ratio is also small and the device100may then determine that the person is within a certain distance.

Additionally, when the person is located at a second further location from the device100, the first PIR sensor2012(1) is able to detect the person while the second PIR sensor2012(2) may not be able to detect the person. As such, the device100may determine that the person is farther from the device100. To make this determination, the device100may determine that a first value associated with the first PIR sensor2012(1) is large, and a second value for the second PIR sensor2012(2) is small. Because of this, the device may determine that the person is further from the device100.

While described herein as using a Fresnel lens in order to create the different first FoVs, in other examples, the device100may additionally, or alternatively, include more than two PIR sensors2012to create the FoVs. For example, the device100may include three PIR sensors2012that generate three FoVs.

FIG.26illustrates select components of the device100, according to examples of the present disclosure. The device100is shown including processor(s)2900and memory2902, where the processor(s)2900may perform various functions associated with controlling an operation of the device100, and the memory2902may store instructions executable by the processor(s)2900to perform the operations described herein.

The device100includes the camera110for capturing image/video data2904within an environment of the device100. In some instances, the camera(s)110may include red, green, blue, depth (RGBD) camera(s) and/or three-dimensional (3D) sensors. Additionally, the device100may include any other sensor(s)2906(e.g., the ambient light sensor2006) that generates sensor data2908. Further, the device100may include the PIR sensor(s)2012that generates the sensor data2908. In some instances, the PIR sensor(s)2012act as motion sensors for detecting movement within a FoV of the PIR sensor(s)2012. The PIR sensor(s)2012may reside behind a sensor lens (e.g., a Fresnel lens) of the device100. In such examples, the PIR sensor(s)2012may detect IR radiation in a FoV of the PIR sensor(s)2012, and produce an output signal (e.g., voltage) that changes as the amount of IR radiation in the FoV changes. The amount of voltage in the output signal may be compared, by the processor(s)2900, for example, to one or more threshold voltage values to determine if the amount of voltage in the output signal is indicative of motion, and/or if the amount of voltage in the output signal is indicative of motion of an entity that is to be recorded by the camera(s)110. In some instances, the PIR sensor(s)2012may detect the motion for activating the camera(s)110and/or the microphone(s)2306to begin capturing image data and/or audio data, respectively.

In some instances, the PIR sensor(s)2012are used to detection motion within an environment of the device100. However, in some instances, the camera(s)110, in addition to or alternative from the PIR sensor(s)2012, may be used to detect motion. For example, computer vision techniques may be used to detect objects of interest. In some instances, the camera(s)110may include a CMOS image sensor, and a digital processor that may perform embedded processing within the low-power CVM itself, such that the low-power CVM may output post-processed computer vision metadata to the processor(s)2900. The metadata may include information such as the presence of a particular type of entity (e.g., person, animal, vehicle, parcel, etc.), a direction of movement of the entity, a distance of the entity from the device100, etc. As a result of including the computer vision, the device100may leverage computer vision to implement computer vision for one or more aspects, such as motion detection, object recognition, and/or facial recognition. Computer vision includes methods for acquiring, processing, analyzing, and understanding images and, in general, high-dimensional data from the real world in order to produce numerical or symbolic information, e.g., in the form of decisions. Computer vision seeks to duplicate the abilities of human vision by electronically perceiving and understanding an image.

The device100also includes LED(s)2910, such as IR LEDs and/or white LEDs, for illuminating and/or emitting light within the environment of the device100. Any number of IR LEDs and/or white LEDs may be included, and the IR LEDs and the white LEDs may be arranged about various sides of the device100(e.g., front, sides, etc.). In some instances, in response to the PIR sensor(s)2012and/or the camera(s)110detecting motion, the LED(s)2910may receive an output signal from the processor(s)2900that causes the LED(s)2910to activate the one or more lights. The IR LEDs may also be used to detect motion and/or record image/video data2904in low-light conditions. The LED(s)2910may also output indications associated with an operational status of the device100. The LED(s)2910may be representative of the lighting elements900within the light assemblies104, the first lighting element2300, and/or the second lighting element.

The device100includes the microphone(s)2306that generate audio data2912. Speaker(s)2100may output sound in a direction away from the device100. The sound output by the speaker(s)2100may include the audio data2912, which may be received from one or more communicatively coupled device, or other audio (e.g., siren, alarm, etc.).

Network interface(s)2914permit the device100to communicate over one or more networks. Example network interface(s)2914include, without limitation, Wi-Fi, Bluetooth, ZigBee, Bluetooth Low Energy (BLE), LTE, and so forth. The network interface(s)2914permit communication with remote device(s), such as mobile devices (e.g., phone), systems (e.g., cloud), and so forth. The network(s) may be representative of any type of communication network, including data and/or voice network, and may be implemented using wired infrastructure (e.g., cable, CAT5, fiber optic cable, etc.), a wireless infrastructure (e.g., RF, cellular, microwave, satellite, Bluetooth, etc.), and/or other connection technologies.

In some instances, inbound data from may be routed through the network interface(s)2914before being directed to the processor(s)2900, and outbound data from the processor(s)2900may be routed through the network interface(s)2914. The network interface(s)2914may therefore receive inputs, such as data, from the processor(s)2900, the camera(s)110, the PIR sensor(s)2012, and so forth. For example, the network interface(s)2914may be configured to transmit data to and/or receive data from one or more network devices. The network interface(s)2914may act as a conduit for data communicated between various components and the processor(s)2900.

Although certain components of the device100are illustrated, it is to be understood that the device100may include additional or alternative components. For example, the device100may include other input/output devices (e.g., display screen), heat dissipating elements, computing components (e.g., PCBs), antennas, ports (e.g., USB), and so forth).

As used herein, a processor, such as the processor(s)2900may include multiple processors and/or a processor having multiple cores. Further, the processor(s) may comprise one or more cores of different types. For example, the processor(s) may include application processor units, graphic processing units, and so forth. In one implementation, the processor(s) may comprise a microcontroller and/or a microprocessor. The processor(s) may include a graphics processing unit (GPU), a microprocessor, a digital signal processor or other processing units or components known in the art. Alternatively, or in addition, the functionally described herein can be performed, at least in part, by one or more hardware logic components. For example, and without limitation, illustrative types of hardware logic components that may be used include field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), application-specific standard products (ASSPs), system-on-a-chip systems (SOCs), complex programmable logic devices (CPLDs), etc. Additionally, each of the processor(s) may possess its own local memory, which also may store program components, program data, and/or one or more operating systems.

Memory, such as the memory2902may include volatile and nonvolatile memory, removable and non-removable media implemented in any method or technology for storage of information, such as computer-readable instructions, data structures, program component, or other data. Such memory may include, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, RAID storage systems, or any other medium which can be used to store the desired information and which can be accessed by a computing device. The memory may be implemented as computer-readable storage media (“CRSM”), which may be any available physical media accessible by the processor(s) to execute instructions stored on the memory. In one basic implementation, CRSM may include random access memory (“RAM”) and Flash memory. In other implementations, CRSM may include, but is not limited to, read-only memory (“ROM”), electrically erasable programmable read-only memory (“EEPROM”), or any other tangible medium which can be used to store the desired information and which can be accessed by the processor(s).
