Review on HDMI KVM USB Extender: Transmit 1080p HD Video Over Cat5e/6 Ethernet Cable 50m (164ft) for Remote Mouse and Keyboard Control Signals by Derick Johns

I ordered these extensions for use with a CCTV DVR I was planning to install in a customer's basement so the fan noise wouldn't disturb its working environment . . I ran a CAT6 Plus cable for the cameras themselves and another cable from the NVR to the TV he was planning to use as a monitor and I have to say they worked GREAT! I used a Logitech wireless mouse with it and got full 1080p video with mouse control at about 70ft over CAT6 cable as if I was sitting right in front of the NVR itself. I can not complain. The price was MUCH cheaper than many of the other options and they work exactly as advertised. I intend to buy these devices again if the need arises.
