AL37219
9 Channel Video Surveillance processor
Description
AL37219 is a 9-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 AL37219 chip can
provide 9-CH real time surveillance system.
Two chips can be cascaded together to
provide 16-CH real-time application.

It can be combined with AverLogic’s MPEG4
encoder (AL9V576) and video decoders
(AL240) to provide high quality surveillance
systems with cost effective solution. Its 4
channel counterpart, AL37204, can be used
for real-time 4-CH surveillance applications.
