CG-4 FOUR CHANNEL CAMERA GUARD The CG-4 Camera Guard system supervises the continuity of four separate video or HD-TVI signals from CCTV cameras. This supervisory system will identify loss of a video signal due to removal of the camera, loss of power to the camera or a camera cable disconnect. The CG-4 supervisory system continuously displays the “video on” condition of 4 cameras, with individual L.E.D. indicators for each video channel. Normally Open or Normally Closed Alarm contacts are provided for each channel to send an alarm or activate equipment when loss of video occurs. These contacts are field programmable for Normally Open or Normally Closed contact operation. This unit can be connected to a local alarm to alert monitor personnel that a camera is being tampered with or send a message to a remote site by connecting the alarm output to external dialing equipment. The CG-4 will identify tampering or failure of cameras when it occurs, reducing the liability associated with extended and undetected loss of area security when cameras are rendered in-operative without notification. The CG-4 increases the level of security provided by the CCTV system. The CG-4 Camera Guard can be connected anywhere between the camera and the Monitor equipment in the video path. You can connect it near the camera to activate a local alarm or at the monitor location to alert guard personal. It provides a “Loop- through Input” that will not affect the picture quality or the video level. The unit detects a loss of SYNC that indicates the power to the camera is off, the coaxial cable is “disconnected” or the Wireless Transmission system/Fiber optic system has lost its signal. Use this unit in any CCTV installation that requires guaranteed continuous video monitoring. Use the CG-4 to monitor the cameras in sensitive areas like loading docks or any area subject to the unauthorized movement of product or stock. Or use it to determine if you have an intermittent failure problem in any CCTV system. The CG-4 has an easy mounting flange that will mount to any surface with just two screws and is supplied with a 24 VDC power cube.
