Commercial accident witness or 'Dash Camera's' are almost a necessity in today's environment. This can be used to protect drivers from many issues faced on the roads. Whether, it is a staged 'cash for crash' accident, or conflicting reports of events, or to back a statement up for the driver or to protect from huge accident claims. In addition, the commercial camera's can point towards exonerating the driver from false speed camera readings and traffic signal violations and more. Some of the camera's we sell are 2-channel systems, meaning they are 2 camera's, 1 recording the forward facing at the front of the vehicle and the 2nd rear facing recording at the rear of the vehicle. These camera's require an SD card to record data, which are included in some of the packages (please see individual products for more details).
