Harris Corporation Adds Video Surveillance to Intraplex NetXpress for Broadcast Transmitter Site Security


Harris Corporation (NYSE: HRS), an international communications and information technology company, will introduce a new video surveillance application for its Intraplex® NetXpress™ audio over IP platform at NAB Radio 2007. Harris will be located in Booth #311 at the Charlotte Convention Center during the conference, being held September 26-28.

“Transmitter site security has always been a concern,” said Chuck Alexander, director, Intraplex products, Harris Broadcast Communications. “The integration of sophisticated video analytics capabilities at these remote sites has made it possible to reliably detect unauthorized entry while only transmitting video on alarm or on demand.”

Harris first introduced Intraplex® NetXpress™ in late 2005 as the industry’s first managed platform for the transport of audio over IP. The managed networking platform can send multiple services, including audio, data and PBX telephone communications, over a single IP connection.

The new video surveillance application uses low bit-rate MPEG-4/H.264 video compression to send and receive multicast or unicast video, which can be viewed on one or more PCs anywhere on the IP network. Video analytics software in the new video encoding module for the Intraplex® NetXpress™ chassis automatically detects people entering designated areas, or objects taken or left behind, and sends alerts complete with still images or full-motion video over the IP network to alert personnel at the studio or security office. Alarm logs maintain records of these events along with associated images.

NetXpress® frames residing at both the studio and transmitter site — the traditional NetXpress™ setup for sending multiplexed services in a single stream from studio to transmitter — would feature the new video module for surveillance purposes, with connections to on-site cameras for real-time analysis and live video feeds.

The NetXpress™ platform retains the reliability and robustness of Intraplex® legacy T1/E1 STL platforms, while continuing to incorporate new features that bridge broadcast and telecom applications for radio stations and streamline conversions to STL transport over IP via T1/E1 circuit emulation. Its ability to transport multiple audio programs in multiple formats — including HD Radio™, data, and PBX telephone communications — over a single IP connection, offers a more cost- and bandwidth-efficient transport network than separate wired T1 circuits, microwave or fiber T1/E1 circuits.

Other NetXpress™ features include the ability to link services across combined T1 and IP networks; adjustable compensation for IP network jitter; Quality of Service (QoS) tagging; and forward error correction to improve IP transport reliability.
