PATENT DESCRIPTION
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention is directed to surveillance systems; to such systems with multiple surveillance units in remote locations; and, in certain particular aspects, to such systems with units spaced-apart by relatively large distances. 
         [0003]    2. Description of Related Art 
         [0004]    There are a variety of known surveillance systems, some stationary, some portable, which include one or more cameras (still and video); lights; sensors (motion; infrared; environmental, e.g. gas, temperature, humidity); motion detectors; power supplies; microphones; control systems; remote access systems; monitors; alarms; electronics equipment; and enclosures. 
         [0005]    Known systems include supports and masts (single piece and telescoping) to which various items are connected. Certain known systems are mounted on a variety of vehicles, including trailers, cars, trucks, and tracked vehicles. 
         [0006]    Problems and disadvantages of known systems include: with certain known systems it is difficult or impossible to communicate using satellite systems due to insufficient available bandwidth. Certain known systems do not provide mesh communications. Certain known systems use only discrete remote units that act as individual disparate systems with no unification or communication with a central system and with such known systems it is not possible to view multiple remote units from a single unified platform (a platform that allows a user to simultaneously view multiple remote nits at multiple remote locations using one piece of software on a single computer). with certain known units there is no local archiving at the unit which would conserve bandwidth; and with certain known units there is no system involving multiple units one of which has a local archiver which some of the units can share. 
         [0007]    Industrial sites, including, but not limited to, oilfield locations, pipelines, and oil and gas drilling and production facilities are often in remote areas where access is difficult and power which is at a premium is often generated on-site. Monitoring such sites presents particular problems; e.g. in providing power generation and communications facilities on-site. 
         [0008]    U.S. Pat. No. 4,709,265 discloses a remote control mobile surveillance system for hazardous environments and the like having a radio remote controlled vehicle that is sized and shaped for optimum maneuverability and stability, including mobility on stairs and inclined surfaces. The vehicle is designed to have a low center of gravity that is shiftable up and down, front to rear and side to side under operator control in order to provide stability. The top deck of the vehicle is uniquely shaped and is adapted to support any of several payloads, including an articulated arm module that is moveable in a pan and tilt direction and a smear sampler mechanism for repeatedly taking surface samples. The vehicle is moved by independently operated, motor driven tracks located on each of the two longitudinal sides of the vehicle and is adapted to move in a forward, reverse and rotational directions. Remote monitoring is provided by stereoptic TV cameras, stereo sound, and variety of environmental sensors. In one aspect, such a system has: an operator control center, the center having manual command operation and transmission means, telemetry receive and reporting means and antenna means; and a surveillance vehicle located remote from said control center and in wireless communication therewith; the vehicle having chassis means sized and shaped to fit within standard doorways and stairways and to provide an optimally low center of gravity for the vehicle; propulsion means adapted to provide movement to the vehicle and mounted on the chassis means and having at least two independently controllable motor and track means, cover means removably mounted on the chassis means and adapted to support a plurality of payloads, payload means adapted to be movable in at least one direction and to have mounted thereon an operative load means, the payload means being removably mounted on the cover means; communications means adapted to receive commands from and transmit telemetry to the operator control center, the means being operatively connected to the propulsion means and the payload means, whereby an operator at the operator control center can remotely control and monitor the movement of the vehicle and the operation of the payload means, the cover means being substantially rectangular in shape, having a vehicle front, a vehicle rear and two longitudinal side edges, a centrally located planar portion on which is mounted the payload means and a front planar apron portion extending from the payload at an angle downward to the vehicle front edge, and the payload means being adapted to move the operative load forward and below the centrally located planar position, along the planar apron position of the cover means, whereby the center of gravity of the vehicle may be moved lower and forward dynamically during movement of the vehicle up an inclined surface under remote control from the operator control center. 
         [0009]    U.S. Pat. No. 4,815,757 discloses rapid development surveillance vehicles and methods which are for detecting illegal immigration across national borders and the like. An off-the-road vehicle is equipped with a rapid mast erection/retraction assembly which includes a carriage mechanism which carries a telescoping mast. A track mechanism slidably carries the carriage mechanism by means of a fixed support and pivoting support arms. Ram air cylinders move the carriage mechanism in translational and rotational movement as guided on the track mechanism in a manner that the mast is moved from a stowed horizontal position to an erect vertical position. During erection of mast, a longitudinal roof opening is opened by means of a main door and displacement door in an automatic manner. Once erect, a leveling system checks to ensure that the vehicle is within one degree of level. Both level sensors and pressure sensors ensure that the vehicle is level and that all four jack legs are firmly engaged against the ground prior to extension of mast. Once the vehicle is within the prescribed level conditions, mast is pneumatically extended to a height of thirty feet whereupon a detection device which may be in the form of an infrared camera is ready for surveillance. The camera is mounted on a pan/tilt device which rotates it in a horizontal plane and tilts it in a vertical plane for increased surveillance. With the mast within one degree of true vertical, a stable platform is provided for the camera so that a nondistorted image appears on the display of a monitor remote from the camera. In one aspect, a rapid deployment surveillance vehicle is disclosed from which a detection device may be rapidly deployed from a stowed concealed position within a vehicle to an elevated vertical position for surveilling a detected event having: a mast on which the detection device is carried; a rapid erection/retraction system carried within the vehicle for deployment of the mast and detection device from the stowed, concealed position to an initial erect vertical position; a mast extension system for extending the detection device vertically to the elevated position elevated from the initial erect position considerably above the vehicle; a leveling system for leveling the vehicle during the time that the detection device is extended to the elevated position which includes: jack means carried adjacent each corner of the vehicle for engaging the ground and raising the vehicle, drive means for actuating the jack means, level sensor means for sensing a level condition of the vehicle and generating a level signal representative of the level condition, and control means for controlling the mast extension system and the leveling system in conjunction with each other, the control means controlling the drive means in response to the level sensor signal for simultaneously controlling the jack means and leveling the corners and the vehicle continuously while the detection device is extended to the elevated position, and the level sensor means continuously sensing the level condition for generating the level sensor signal while surveilling the detected event, platform mounting means for mounting the detection device to a free end of the mast; and the control means of the leveling system controlling the jack drive to level the vehicle continuously during surveillance for maintaining the extended mast within a prescribed range of true vertical so that the detection device is stably carried by the mast in the elevated position providing a stable, enhanced image of the detected event on the display of a monitor continuously while surveilling the detected event.

A system  202  is in communication with a control system  64 , and/or a central server (like the server  120 ,  FIG. 6 ). Any suitable known radar system may be used; including, but not limited to, known perimeter surveillance radars. 
         [0057]      FIG. 3  illustrates one scheme for a surveillance unit  10  (e.g. as shown in  FIGS. 1A ,  1 B). An external power source ED (e.g. a system  50 ) powers a battery BC which charges batteries in a battery bank BB (e.g. all at 12 volts). The battery bank BB provides electrical power (e.g. at 12 volts) to the local archiver  60  (and its various components and systems with voltage inversion as required); to an ethernet switch  77 ; to the PTZ camera  24 ; to indoor and outdoor satellite units; and to the fixed camera  20 . 
         [0058]    Optionally, as shown in  FIG. 4 , communication is provided to a surveillance unit according to the present invention via a satellite system SS which includes a satellite outdoor unit SO connected to a satellite unit SP. The local archiver  60 , etc. are connected via standard computer networking protocol, e.g. an ethernet connection, “ETHERNET”. 
         [0059]      FIG. 4  also illustrates a power scheme for a surveillance unit  10  which includes a solar power system SP with a photovoltaic array AR (“PV Array”). The solar power system SP provides power (e.g. at 24 volts) to a charge controller CC which charges batteries in a battery bank (all e.g. at 12 volts). Optionally, an external power system EX (e.g. a system  50 ) powers a battery charger BY (e.g. at 120 volts) which in turn charges batteries in the battery bank BB (e.g. at 12 volts). The charge controller CC provides power (e.g. at 12 volts) to the ethernet switch  77 ; the camera (e.g. a camera  20  or  24 ); the cellular router  78 ; and to the local archiver. “ETHERNET” between the three items in  FIG. 4  indicates data communication, including video data. 
         [0060]      FIG. 6  illustrates a system  100  according to the present invention which includes multiple surveillance units  110  according to the present invention (e.g. like any surveillance unit according to the present invention, e.g., but not limited to, the surveillance unit system  10  and  10   a ). The surveillance units  110  can be at different locations or sites and they can be separated by relatively large distances, e.g. many miles. 
         [0061]    A central server  120  with an archiver  121  is in communication with all the surveillance units  100 . A client whose sites, locations, and/or equipment is under surveillance via the surveillance units  110  communicates with the central server  120  via any known method or system of communication. As shown this communication is via a network (“NET”) which can be the internet or any private network. The central server can serve as a single unified platform at which the client can monitor and/or view multiple remote units according to the present invention using one piece of software on a single computer. 
         [0062]    The line labelled  132  (“VIDEO FLOW”) indicates the transmission of video data from a unit to a client and provides the client real time access to streaming video from each video camera of each surveillance unit (and, in some aspects, access to archived video of each camera). 
         [0063]    A local archiver  112  is in communication with its own surveillance unit  110   a  and via any suitable form of communication (wired or wireless) with several other surveillance unit systems  110   a ,  110   b , and  110   c . Via a satellite uplink system  114 , the local archiver  112  is in communication with a satellite system  118  which in turn communicates with a teleport  140  (a main downlink/uplink hub for satellite communication). The teleport  140  conveys the information from the local archiver  112  to the NET network. This includes every type of information from every component, camera, sensor, detector, etc. of the surveillance units  110   a - d . The teleport  140  is also in communication, via the satellite system  118 , with a local archiver  115  of a surveillance unit  110   a  spaced-apart from the surveillance unit  110  with the local archiver  112 . The surveillance unit  110   c  which may not be able to communicate with the local archiver  112  (e.g. due to distance, terrain, conditions), communicates with either unit  110   b  or  110   d , each of which then communicates data from the unit  110   c  to the local archiver  112 . 
         [0064]    Line  134  indicates the transmission of video data from the archiver  112  to the NET network. 
         [0065]    A cellular router  117  with an antenna  119  of a surveillance unit  110   f  communicates with the NET network. Optionally an intermediary network NTK is used. 
         [0066]    The archiver  121  of the central server  120  communicates via a network NTW with a local archiver  160  of an office  162 . For example, the office  162  is a field office at a construction site which may have multiple cameras, e.g. sixteen cameras (viewable at the office and/or at a remote location). The office  162  and the router  117  may communicate with the NET network via a virtual private network (“VPN”). 
         [0067]    In one aspect of a method according to the present invention a remote user accesses a single camera of a unit according to the present invention over a cellular internet connection to view the camera. Multiple cameras could be added to this unit and accessed in the same manner whether the network connection is cellular, satellite, etc. In this mode, the trailer (or trailers) acts as an independent unit not joined in any particular network. 
         [0068]    In another aspect of a method according to the present invention with a unit according to the present invention with a camera or multiple cameras that is part of a larger network of units, each unit communicates with a central server over cellular, satellite, etc. The server manages the connections between the units and remote viewers, and the central server archives video from each and/or every camera if desired. A user connects to the central server, and then accesses each unit and its associated cameras and sensors for viewing. If the central server is recording video data, then the user can view the recorded video. The communication between the units and central servers takes place over a Virtual Private Network, while the user connection to the server does not necessarily need to take place over a VPN. 
         [0069]    In one aspect in a system and method according to the present invention a unit according to the present invention with a local archiver onboard records video for each of a plurality of cameras on the unit. The unit connects to a central server for user connections and management purposes. The user is able to access recorded video data from the unit&#39;s local archiver. The unit need not continuously stream video to the central server for recording purposes since recording is occurring locally on the local archiver. This system (and those like it according to the present invention) is not limited in bandwidth as are some remote communications methods which employ satellite or cellular limited bandwidth systems, and/or which are charged per bandwidth used. Using a local archiver according to the present invention allows for recording more camera video streams than could fit over a limited network connection. For example, with four cameras in a system according to the present invention with a bandwidth requirement of 128 kbit/sec each camera is connected to a local archiver that only has a single 128 kbit/sec satellite connection. Only one camera is remotely viewed live at a time, but all four are continuously recording locally. The unit-to-central-server connections, in one particular aspect, can take place over a VPN. 
         [0070]    In one aspect of systems and methods according to the present invention multiple units are connected to a single main unit that contains a local archiver and a satellite or cellular connection. Every camera on every trailer in this small local network records its video to the main unit&#39;s local archiver. The local unit network may be a wireless mesh network, wired fiber optic network, etc. 
         [0071]    For any system according to the present invention, a client can directly access a unit according to the present invention over a network connection, e.g. an internet connection. Alternatively, a client can access a central server, which acts as a proxy to the unit(s) according to the present invention. 
         [0072]    It is within the scope of the present invention for any unit according to the present invention to have heater apparatus H (see  FIG. 1B ) and/or cooler apparatus C (see  FIG. 1B ) in or adjacent any part of the unit, including, but not limited to, in or adjacent the unit&#39;s main body (trailer enclosure, housing, etc.); in or adjacent a control system; in or adjacent a local archiver; and/or in or adjacent an electronics enclosure.
