Known colloquially as the ?black box of the tracks?, the March Networks 4120 digital video recorder from distributor Norbain is fully compliant with the rail industry’s testing standards (BRB/RIA 12, 13, 18, 20 and BS EN61373, EN61373) to ensure continuous performance despite exposure to vibration and shock. Following almost 12 months of testing, the 4120 DVR has succeeded in achieving rail industry approval. Chris Harper, Norbain?s Transport Account Manager, says: ?On-board CCTV acts as a deterrent but needs to be of a high enough quality to withstand vibration and impact so that, in the event of an incident, evidential quality footage is available. The March Networks 4120 DVR achieves the level of robustness and performance required by this most demanding of industries.? Features of the 4120 DVR include an EMI proof, dustproof and waterproof chassis, fail safe battery backup operations, flexible installation and mounting configurations and a conditioned power supply output for up to four cameras. The recorder can be connected to a portable computer, or accessed remotely via a wireless GSM connection; or removed from its operational environment for connection to a local or wide area network. The product stores about seven days of continuous recording onto its 10 GB drive (one camera at 15 frames per second) that can be expanded by the addition of a further 10 GB hard disk. A variety of capture resolutions are supported at frame rates of less than one fps up to 15 fps. Norbain?s UK transport customers include London Underground and Bombardier.
