HDMI cabling is limited to 50 feet and is a bulky/difficult to route.  Cat-5e/6 extenders for HDMI solve both problems.  While there is nothing unique about a Lifesize camera as an HDMI video source (try connecting one to a display),  there is something unique about how we handle pan/tilt/zoom control for Lifesize cameras over HDMI.


Pan/Tilt/Zoom control makes use of the HDMI DDC channel, so any device inserted between a Lifesize camera and Lifesize codec that manages/caches/interupts DDC communication will interfere with pan/tilt/zoom control of the camera.  (Video switches are a classic example).  Many HDMI extenders do in fact manage DDC communication and should be avoided.  Finding out how a particular extender deals DDC is often omitted from product datasheets unfortunately.  Thankfully our fantastic engineering team has validated a few models in for use between a Lifesize Camera and Lifesize Icon 600/800.


We have successfully tested with the Sound Control Technologies RemoteCam4 RC4-L22 (shielded cat-5e: 285ft, shielded cat-6: 300ft)
