Input Voltage

The input voltage is +8V to +36V. lt is recommended to input avoltage of 12V or above for the camera to work. Do not exceed 36V for a long time to avoid burning the machine.

Power Consumption

No-load < 4.5W, with the camera working < 10W

Output Voltage

ouput voltage 12V(+0.2V), maximum current 3A

ACC Detection

≤9V the car key is turned off and the device is turned off

≥10V the car key is turned on, and the device is turned on
