Description



The AL37204 controller is Averlogic's 4-ch control solutions for multiplexer, DVR and Video Server CCTV applications. Both controllers provide an additional input channel for playback and three separate output paths providing 8 bit ITU-R BT.656 and/ or 24 bit RGB format data for maximum flexibility meeting digital video recording and LCD TV/ monitor display requirements.

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.

AL37204 can be combined with AverLogic's MPEG-4 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.
