- Support NTSC and PAL standards
AL37204 is a 4-CH video surveillance
- A single chip supports 4-CH real-time
processor that empowers any surveillance
system with rich set of features. They include:
surveillance
simultaneous monitoring-playback-recording
- Support Triplex operation, (i.e., simultaneously
real-time monitoring + recording + playback).
operation, flexible video display mode,
- Support (at least)1,2,4,6,7,8,9,10,13,16 and
bitmapped and dynamic colored OSD, rich
multi- windows display modes
modes of recording, accurate motion
- Support PIP /POP display modes
detection (16X12 grids) with flexible
threshold and trigger methods, replay on all
