Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims benefit from U.S. Provisional Patent Application Ser. No. 62/597,234, filed Dec. 11, 2017, which is incorporated by reference in its entirety. 
    
    
     STATEMENT REGARDING GOVERNMENT INTEREST 
     None. 
     BACKGROUND OF THE INVENTION 
     The present invention relates generally to monitoring, and more particularly to a wireless remote video monitor. 
     In general, parents of infant children often use video systems to monitor young children, such as infants in cribs. These systems typically consist of a camera wirelessly linked to a monitor in which a parent may view a live picture of the infant and in some implementations, listen to audio of the infant. These systems are most often used to monitor the infant while sleeping. 
     What is needed is a system which alerts a viewer if an infant moves out of a designed area, such as a crib, or when someone approaches the infant and breaches into the designated area. 
     SUMMARY OF THE INVENTION 
     The following presents a simplified summary of the innovation in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is intended to neither identify key or critical elements of the invention nor delineate the scope of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented later. 
     In an aspect, the invention features system including a camera wirelessly linked to a base station, the base station including at least a graphical user interface (GUI), a user adjustable boundary positioned about a subject displayed in the GUI, means for detecting motion across the boundary, and means for sounding an alarm in response to the detected motion. 
     In another aspect, the invention features a method including providing a camera wirelessly linked to a base station, displaying a graphical user interface (GUI) on the base station, the GUI including an image of a subject captured by the camera, positioning a boundary around the image in the GUI, detecting motion across the boundary, and generating an alarm in response to the detected motion. 
     These and other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that both the foregoing general description and the following detailed description are explanatory only and are not restrictive of aspects as claimed.

     DETAILED DESCRIPTION 
     The subject innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It may be evident, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the present invention. 
     As shown in  FIG. 1 , an exemplary wireless remote video monitoring system  100  includes a camera  110  and a monitoring base unit  120 . The camera  110  is wirelessly linked to the monitoring base station  120 . In one implementation, wireless 2.4 GHz FHSS technology is utilized, which offers a reliable connection for better range and less chance of a dropped signal. In one implementation, the camera  110  can include pan, tilt, and zoom features. The camera  110  is typically positioned near an infant, such as an infant sleeping in a crib. The camera  110  captures real-time video and audio in a baby&#39;s room. The monitoring base unit  120  is typically remotely positioned so that it is convenient for a user (e.g., parent) to set-up and utilize away from the camera  110 . 
     As shown in  FIG. 2 , the monitoring base unit  120  includes body  210  and a display  220 . The body  210  may contain one of a processor and memory. The display  220 , which may be color LCD, presents a graphical user interface (GUI)  230 . The body  210  includes a number of control buttons  240  that enable a user to setup and control the monitoring base unit  120  and its wireless connection to the camera  110 . 
     As shown in  FIG. 3 , the GUI  230  displays live video from the camera  110 . In this example, the GUI  230  is used to display an infant  300  in, for example, a bed. In addition, the GUI  230  includes a boundary feature. More specifically, the GUI  230  enables a user to establish a boundary shape  310  around the infant  300 . Although the boundary shape  310  as implemented in  FIG. 3  as a rectangle, other embodiments implement the boundary shape  310  as geometric shapes, such as a square, a circle, an oval, a triangle, a rhombus, and so forth. The boundary shape  310  is user controllable and thus adjustable so that the entire infant  300  is displayed within the boundary shape. 
     The monitoring base unit  120  includes a process  1000  that detects any motion crossing over the boundary shape  310 . Process  1000  includes video motion detection (VDM) technology that changes in the pixels within the thickness of the boundary shape  310 . More specifically, VDM is used to trigger alarms in the monitoring base unit  120  by sensing physical movement in a given area. The VDM uses a simple algorithm which continually analyses current live image data against a reference image from a previous frame. Any significant changes triggers an alert. This alert can be used to initiate many actions such as moving a pan-tilt-zoom camera to a specified point or operating an external device such as turning on a light or sounding an alarm, and so forth. 
     In the present application, the boundary shape  310  has a profile thickness of several pixels that creates an invisible boundary around the infant  300  that sends a parent an alert if there are any changes or activities that cross over the boundary shape  310 . A such, regular movements of the infant  300  are not detected, only those movements of the infant  300  that cross the boundary shape  310  or movements of objects that cross the boundary shape  310  toward the infant  300 . 
     As shown in  FIG. 4 , process  1000  includes providing a camera ( 1100 ) wirelessly linked to a base station. Process  1000  includes adjusting ( 1200 ) the camera to focus on a subject. 
     Process  1000  includes adjusting ( 1300 ) a size of a boundary box around the subject displayed on a graphical user interface (GUI). 
     Process  1000  includes detecting ( 1400 ) motion across the boundary box. 
     Process  1000  includes sounding ( 1500 ) an alarm in response to detecting ( 1400 ) the motion across the boundary box.
