Intersil's Security Link over Coax (SLOC) Solution to Enable Wider-Spread Adoption of Digital IP Video Surveillance
New Technology Helps Drive the Transition from Analog CCTV to Networked IP Surveillance
Milpitas, CA – October 4, 2010 – Intersil Corporation (NASDAQ Global Select: ISIL) today introduced an advanced modem solution designed to simultaneously transmit analog CVBS video and digital IP video over a single coaxial cable. The Intersil Techwell SLOC™ (Security Link over Coax) solution uniquely allows modern mega-pixel IP cameras to operate in the existing CCTV coaxial cable infrastructure without the need for new wiring or cable modifications, providing significant cost and resource savings.
Moreover, the Intersil Techwell device enables digital IP camera functionality on existing coaxial wiring infrastructure without disrupting existing CCTV services. In addition, the embedded analog CVBS video enables latency-free live viewing and controlling of digital IP cameras. Surveillance system manufacturers can now architect an effective hybrid surveillance system that supports latency-free analog CCTV functions as well as networked IP surveillance functions.
The solution is comprised of the TW3801, a SLOC-based camera modem PHY device, and the TW3811, a SLOC-based receiver modem PHY device. Based upon Intersil Techwell technology, the combination of TW3801 and TW3811 provides the security surveillance industry with a seamless migration from a traditional analog system to an IP security system. The SLOC technology leverages the installed coaxial cable infrastructure and enables networked IP functions without requiring significant change to either the IP camera design or the DVR (digital video recorder) design.
Both the TW3801 and the TW3811 are highly integrated modem PHY subsystems that include an analog front end (AFE), a digital modem and two Ethernet media independent interfaces (MII). The TW3801 accepts an analog CVBS signal and an Ethernet MII signal and internally combines these signals into one proprietary output signal for transmission over a coaxial cable. The TW3811 accepts a SLOC output signal from a SLOC-based camera modem PHY IC and decodes it into an analog CVBS and an Ethernet MII signal. The result provides customers with the ability to upgrade their existing analog-based system to the highly feature rich IP security system, including latency-free functionality.
The Intersil SLOC solution provides high-performance and robust communications between the IP camera and the receiver at coaxial cable lengths of up to 500 meters. Downlink throughput is up to 36Mbps (from camera to receiver); uplink throughput is up to 11Mbps (from receiver to camera).
Demonstration Showcases SLOC Technology at Security Essen 2010
Intersil Techwell will provide a demonstration of its SLOC modem PHY IC devices at the Security Essen 2010 show, which will be held in Essen, Germany from October 5th to 8th in Hall GA Booth155. Attendees will experience first-hand the simultaneous transmission of analog CVBS video and digital HD 1080p IP video over a single commodity-priced coaxial cable, streaming from an HD 1080p IP camera to a monitoring station.
Pricing and Availability
Both the TW3801 and the TW3811 are available in engineering samples in the 100-TQFP (12x12mm) package. Mass production samples are slated for Q1, 2011. Pricing for the chipset is estimated at $35.00 each in 1,000-piece quantities. For more information please visit: http://www.intersil.com/Video/SLOC.asp
