Vehicle mounted cameras are used as counter surveillance devices to detect surveillance of a protected vehicle. These cameras are located in forward and rearward looking locations in the protected vehicle and are in communication with vision processing software that a.) identifies license tags of surrounding vehicles, which are then run through various data-bases of friends and foes, and b.) records surrounding vehicle movements in an attempt to identify trailing vehicles that (for instance) remain within a certain distance of the protected vehicle for long periods of time, or fit other criteria. |
