How to connect a DVR to TV (using HDMI extender)

If you need to carry the video signal from your DVR for long distances, one solution is to use an HDMI extender that allows you to use Category 5 or 6 network cables to extend the signal to distances that can reach up to 120m.

Sometimes you come across that situation where the use of an HDMI cable imposes a limit on the maximum distance to be used, but maybe you need to watch the video on a TV that is far away from the DVR,

If that's you case, HDMI extender will help you to send the video signals from your DVR to a distant monitor, by using UTP cables

HDMI extender options

  • Passive HDMI extender for cables cat5/6 cables
  • Passive HDMI extender for 1 cat5/6 cable
  • Active HDMI extender for 1 cat5/6 cable

The types of extender and prices vary according to the models, for some situations it is feasible to use passive models, for other situations however, active models are recommended.
