24-hour monitoring. It allows you to connect the DVR camera to the vehicle's battery, thus providing continuous power from the battery directly, so that your car's DVR can operate even when the ignition is off.

• Great compatibility. Compatible with most car cameras that USE USB CONNECTION and 5V INPUT.
• Reduces 12V or 24V voltage to a steady 5V, thus providing power to the camera.
