Video Grabber DGR-1000 User Manual - v. 1.4 (FW 1.9)

5

1.

General description

Video Grabber DisplayPort (DGR-1000) is a real-time video capturing device that works using the
DisplayPort 1.2 interface. Equipped with a passive video splitter it can be safely installed between the
computer and its screen (Pass-through connection – See 3.2, p. 8) as it doesn’t even have to be
powered on to forward the video signal to the display

1

. In cases where absolutely no interference in

the recorded signal is allowed DGR-1000 can even emulate a specific monitor and record a mirrored
video signal thus ensuring that the link between video source and the display remains untouched
(Monitor emulation – See 3.3, p. 9).
Configured either using web browser or via SNMPv3 DGR-1000 provides wide variety of possibilities:
both lossless and lossy compression algorithms are available, captured signal can be provided as RTSP
stream or saved at a user-defined network location. Support for Network Time Protocol (NTP) makes
it possible to timestamp the data at the moment of its capture.
Designed for the Air Traffic Control, DGR-1000 provides an option for power and network
redundancy.

1

Integrated video splitter requires at least 500mA on pin 20 of DisplayPort port for passive mode. It can be

provided by the monitor or graphics card (or both)
