SUCCESSFUL trials of CCTV onboard a Nottingham tram have led to a contract to fit the entire fleet of 15 vehicles with equipment from Vision Techniques.
Six cameras cover the vehicle interior, with a further two looking forwards and back. Each camera records three colour frames per second, and the images are stored onboard using a digital video recorder. The images are kept for around seven days, and any important footage can be downloaded and archived off the tram before being overwritten.
If an incident occurs, the tram driver can press a button on the console which will mark the next 15min of footage as well as the previous 15min, allowing easy reference to critical information.
