2 Introduction
2.1 Digital video recorder applications
The Digital Video Recorder 430/451 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, per channel, are guaranteed. For 2CIF and 4CIF, recording is possible by
recording at a lower images per second setting. The recording rate and quality are selectable
per camera. One 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, quad, and
sequenced viewing.
Looping auto-terminating video inputs and outputs, audio inputs and outputs, and alarm
inputs and outputs 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 Control Center Web application via a network for live viewing, playback, and
configuration. Four simultaneous users can control the DVR. The DVR also includes an
authenticity check for both local and remote playback. A dedicated PC player is provided for
playback of secure video files.
