2.1 Digital video recorder applications

The Digital Video Recorder 440/480 Series is a video and audio recording system that records
multiple camera and audio signals while simultaneously providing live multiscreen viewing and
playback. The unit has comprehensive search and playback facilities for viewing stored video.
Once configured, all recording takes place in the background without requiring operator
intervention.
Maximum recording rates for CIF resolution of 30 (NTSC) and 25 (PAL) images per second
(IPS), per channel, are guaranteed. By using only 4 channels you can record 2CIF in real time
(30/25 IPS). Recording at 4CIF is also possible by lowering the IPS setting. The recording rate
and quality are selectable per camera. An internal hard disk provides various storage
capacities for recording.
All models have extensive alarm handling functions and telemetry control. Alarm functions
include motion detection in user-definable areas of the image on any camera input.
The unit can be easily operated and programmed via the front panel control keys, mouse, and
the on-screen display menu system. Two monitor outputs provide full-screen, multiscreen,
and sequenced viewing.
The video inputs, audio input and output, and alarm inputs and output are on the rear panel. A
VGA connector provides output for an A monitor. A CVBS video output in either NTSC or PAL
is also provided for Monitor B. Monitor A displays full-screen or quad digital pictures that can
be frozen and zoomed. Monitor B displays live full-screen pictures.
Use the Web application via a network for live viewing, playback, and configuration. Four
simultaneous users can control the DVR 400 Series. The DVR 400 Series includes an
authenticity check for both local and remote playback. A dedicated PC player is provided for
playback of secure video files.
