The DOD DP4 Hardwire Kit is a Battery Discharge Prevention Device that connects to your car battery and provides constant power to your Dash Cam when the engine is turned off.
In Parking Surveillance Mode, your Dash Cam needs a constant power supply and will detect any motion or impact and record the footage while you are away from the car. The DOD DP4 monitors your car battery voltage and when the battery reaches the low voltage set point (11.5V), it will automatically cut power to the Dash Cam preventing your battery from draining and jump starting.

*Note 1: All Dash Cams will operate without a hardwire kit via the supplied power cord plugged into your cigarette lighter socket. You just won’t be able to use the Parking Mode feature powering the Dash Cam this way as it will shut down when the engine is off.
*Note 2: It is highly recommended that the DOD DP4 be installed by a certified Auto Electrician. Ensure no hardwire kit or Dash Cam wires are cut during installation. Cutting wires will void all warranties.
