2-camera Observer video from a semi truck - from Dieselboss

This is an example of the dual camera Observer "black box" camera system found at www.dieselboss.com. This video shows the front and blind-side cameras recording at the same time as well as the GPS map position of the vehicle. Since making this video, the Observer model has been replaced by the newer Carpa-Dual model found at this link: http://www.dieselboss.com/camera/car_truck_rv_camera_recorder_dual.htm
