A four-channel transmitter/receiver rack, which is rail-approved for trains and trackside, is now available from IndigoVision. The product is approved to European standards EN50121-4:2006, EN50121-3-2: 2006 and EN50155:2007 and, when fitted with a special shock and vibration mount, to BS EN 60068-2-64. Up to four specialist analog surveillance cameras can be connected to the rack, which converts the camera feed to high-quality full-frame rate digital video for transmission over a standard IP network, the company stated. A complete surveillance solution can then be installed using IndigoVision’s Control Center video management software and Windows network video recorder software running on a ruggedized PC connected to the IP network. The four-channel rack is a modular design, which can be fitted with any combination of MPEG-4 or H.264 transmitter or receiver modules. All video, audio, PTZ control functions and digital I/O alarm triggers are transmitted using a single CAT5 UTP cable.
