Combination CCTV Quad Screen Processor and DUPLEX Multiplexer: Suitable for all CCTV Surveillance Cameras in this Catalogue. Connect Four Video Cameras (or other Video Sources) to Quad/Multiplexer Digital Processor which performs an Analog to Digital conversion on signals from each input then digitally constructs a Quad Screen image that is output as a standard 75 ohm 1 v p-p Composite Video signal to Video Monitor for Live Viewing PLUS FULL-SCREEN FULL-RESOLUTION INTERLEAVED IMAGES from each Channel to VCR. These interleaved recorded images are at the FULL RESOLUTION of RECORDING DEVICE. (This contrasts with a recording of a Quad Screen Image where each image is only ONE QUARTER of the resolution of recording device.) Monitor Output for live viewing may be Quad Image, Sequentially Switching Images or any Manually Selected input channel. During replay images may be viewed in Quad Screen, by Channel or in Frozen mode. IMAGES may be REPLAYED WHILE RECORDING IS IN PROGRESS. Alarm inputs, Recover input and Alarm output may be used to control a VCR for 'Event-Only' recording. Audible Video Loss and Alarm buzzers alert user to intrusion and/or interference with Camera video or power supply wiring. Log record of Alarm and Video Loss events. Alarm period is programmable and may be used to control VCR recording period. RS232 interface for remote control using a PC. BETTER THAN SUPER-VHS IMAGE QUALITY
