One basis for a mobile traffic surveillance system is the Everec 410 recorder. You can connect up to two analogue cameras to the Everec 410 to film from either the front or back of the vehicle, for example to record braking and stopping.
Police cars in a number of German States are fitted with the Trajet Everec 410 video security System every year. Trajet PhotoSafe or the specially developed "Videoeigensicherung" video security software is used for archiving/securing evidence. This solution uses a digital signature and encryption to protect the entire documentation process from manipulation and unauthorized use.
