HDMI Cable Distance Guide

[RICHARD MESSINGER]

I have been looking through the web site to find a document that would provide guidance on HDMI supportable distances for connecting the different cameras to the Room Kits.  The only thing i am seing is the two 1.5 and 3 meter cables that you can purchase with the kits.

Looking for design limits for HDMI 2.0 cables for the 4K cameras and monitors to be supported.

Any thoughts or pointed urls?

For 4K on standard cables - 3 metres (10 feet) is the recommended maximum.

If you want to go further, you will need to use boosted/repeater cables.

The 8m presentation cable (CAB-PRES-2HDMI-GR) that comes with the RoomKit codec is an example of a boosted cable - note these are usually directional as well to add to your installation headaches.  Get them around the wrong way and they won't work.

We use some active optical cables here to get up to 20m - but these don't come cheap.

Finally found Cisco Link for the Max distance that the Quad Camera can be away from the codec 9 Meters/30 ft.

Use SCT camera extenders kits for distance over CAT6 cable
