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 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.
