Your Digital Witness... This DashCam driving vehicle recorder gives your vehicle a digital witness to events on the roads you travel. This compact unit automatically records the view out the front windshield of the vehicle when the ignition is turned on with its built in color camera and SD card slot. Date and time shown on video. And the built in crash sensor and internal lithium battery make sure the unit continues to record in the moments after a crash is detected. Now you have a witness in the event of an accident or other disputed circumstance. Video is loop recorded onto a SD card so playback is easy on a laptop or cell phone or immediately on the built in color screen. Audio mute button for phone call privacy when desired. Small size (about 2"x3") allows mounting near rearview mirror without obstructing drivers view. Installation available at an additional $80 charge.
