AL37204 4 Channel Video Surveillance processor Description AL37204 is a 4-CH video surveillance processor that empowers any surveillance system with rich set of features. They include: simultaneous monitoring-playback-recording operation, flexible video display mode, bitmapped and dynamic colored OSD, rich modes of recording, accurate motion detection (16X12 grids) with flexible threshold and trigger methods, replay on all input and playback Channels. One AL37204 chip can provide 4-CH real time surveillance system. It can be combined with AverLogic’s MPEG4 encoder (AL9V576) and video decoders (AL240) to provide high quality surveillance systems with cost effective structure. Its 9 channel counterpart, AL37219, can be used for real-time 9-CH surveillance applications. Application ! ! ! ! ! ! ! ! ! ! ! ! !
