CHAPTER 1
Digital video recorder for security applications
The Divar is a video recording system that can record multiple camera signals
while simultaneously providing live multiscreen viewing and playback. It
combines the functionality of a digital recorder with a multiplexer and a
switcher.
The unit has comprehensive search and playback facilities for viewing stored
video. Once set up, all recording takes place in the background without
requiring operator intervention. Maximum recording rates of 60 (NTSC) and
50 (PAL) images per second in total are guaranteed with unsynchronized
cameras. The recording rate and quality are selectable per camera.
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
and on-screen display menu system. One monitor output provides full-screen,
quad and multiscreen viewing; another spot/alarm monitoring. A keyboard can
be connected for PTZ control and to improve the ease-of-use.
Via a network, the Control Center PC-application can be used for live viewing,
playback and configuration. The Divar includes an authenticity check for both
local and remote playback. A dedicated PC player is provided for playback of
secure video files.
The PC-based Configuration Tool facilitates the setup of the unit.
