AL37204
4 Channel Video Surveillance processor
Description
Features
AL37204 is a 4-CH video surveillance
- Support NTSC and PAL standards
processor that empowers any surveillance - A single chip supports 4-CH real-time
system with rich set of features. They include: surveillance
simultaneous monitoring-playback-recording - Support Triplex operation, (i.e., simultaneously
operation, flexible video display mode,
real-time monitoring + recording + playback).
bitmapped and dynamic colored OSD, rich - Support (at least)1,2,4,6,7,8,9,10,13,16 and
modes of recording, accurate motion
multi- windows display modes
detection (16X12 grids) with flexible
- Support PIP /POP display modes
threshold and trigger methods, replay on all - Independent linear horizontal/vertical (H/V)
input and playback Channels. One AL37204 scaling down factors (ex. 1/2, 1/3, 1/4, 2/3, 3/4)
chip can provide 4-CH real time surveillance - Programmable brightness, contrast and
system.
