Sony Hybrid HD Cameras Examined

Author: John Honovich, Published on Apr 16, 2011

In this note, we examine the significance, application and potential limitations of Sony's recent announcement of what they are calling the 'industry's first Hybrid HD security cameras." This technology is especially interesting as an alternative / competitor to traditional Ethernet over Coax (EoC) solutions offered by Veracity, Comnet and others.

Unlike traditional EoC offerings that use an add-on transceiver, the Sony approach is to embed the adaptor directly into the camera. Sony is using technology from Intersil, which they call SLOC (Security Link over Coax), this technology allows analog composite video and Ethernet to be sent over the same coaxial cable. SLOC is specified at up to 500 Meters with 36Mb/s bandwidth from camera to receiver and 11Mb/s bandwidth from receiver to camera.
