The world of reversing cameras and mobile video surveillance can be complex . Vision Techniques helps you sift through the confusion and decide what you need, and if you need it.
Mobile CCTV is progressing all the time. Closed circuit TV, first used on buses, now comes in the form of Digital Video Recorders (DVRs) – often referred to as MDVRs. DVRs are small – the size of a car radio – and reliable.
There are two storage options – hard disc drive and SD card.
The number of cameras depends on the users requirements – but the reversing cameras generally reange from one to eight.
The location of the cameras depends on individual needs. Typically, a camera points out through the windscreen covering the driving view of the road, and another covers the vehicle loading door. Other cameras may cover the front, rear and side views from the vehicle to assist with reversing.
Using cameras within the cab is a sensitive issue but could be essential to vehicle security. The mobile DVRs can record events and panic buttons can be installed.
Some DVRs can be linked to the electronic ‘brain’ of the vehicle, recording fuel consumption and engine information. This is done through CANbus, CANbus (controller area network) which is the standard in vehicle communication.
It is also possible to ‘stream’ videos over a mobile phone network.
