SLOC (Security Link Over Coax) is Intersil’s advanced
communication technology that simultaneously transmits
analog CVBS video and digital IP video over a single coaxial
cable. This innovative technology enables modern mega-
pixel IP cameras to operate in the existing CCTV coaxial
cable infrastructure without the need for new wiring
or modifications. Having both analog CVBS video and
digital IP video in the same coaxial cable enables system
manufacturers to architect cost-effective hybrid surveillance
systems supporting both traditional analog CCTV and
modern networked IP surveillance products.
Intersil’s TW3801/3811 is a set of ICs designed for security/
surveillance applications. The TW3801 is the transmitter on
the camera side, and the TW3811 is the receiver on the DVR/
network side. The combination of the TW3801 and the TW3811
enables high-performance, robust communication link
between the camera and the receiver, operating over a very
long coaxial cable.
