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 Extron DTP HDMI 4K 330 Tx (Part # 60-1331-12) and DTP HDMI 4K 330 Rx (Part # 60-1331-13) transmit/receive extender pair: (shielded cat-5e: 150ft, shielded cat-6: 200ft)
We have successfully tested with the Sound Control Technologies RemoteCam4 RC4-L22 (shielded cat-5e: 285ft, shielded cat-6: 300ft):
We have successfully tested with the Cables To Go HDMI® HDBaseT over Cat5 Extender Box Transmitter 29241 and Receiver 29269 (shielded cat-5e: 250ft, shielded cat-6: 300ft)
