Milpitas, Calif., U.S.: Intersil has expanded its Techwell SLOC (Security Link Over Coax) standardisation ecosystem, designed to accelerate the global adoption and implementation of hybrid IP-based security systems for the video surveillance market (see the figure). The company has joined forces with nearly 100 others, including Sony, Altronix, and Hikvision, to address the need for increased security in next-generation video surveillance systems.
SLOC is a modem physical-layer technology that enables high-resolution megapixel and HD IP-based cameras to operate within the existing analogue CCTV coaxial cable infrastructure without the need for new cabling. It consists of a camera transmitter and a DVR/NVR receiver, a combination that enables high-performance and robust bidirectional communication between the camera and the video recorder over long cable runs.
SLOC supports up to 500 m of coaxial cabling, eliminating repeaters. Embedded analogue CVBS (color, video, blanking, sync) video features enable latency-free live viewing and control of digital IP cameras.
