The dashcam does not shut down after the car ignition switch is turned off?

Why an AZDOME dash cam stays on after the engine is off — car charger vs. hardwire kit power and ACC wiring.

Confirm the dashcam version: Some models have different power cables for car charger version (powered by cigarette lighter) and hardwire kit version (powered by fuse box). If the dashcam is of the car charger version and uses a hardwire kit for power, the dashcam will not turn off automatically after the car ignition is off because the hardwire kit is connected to B+ constant power, so it will continue to operate.
If the car charger version of the dashcam is powered by the car charger and does not turn off after the car ignition is off, you can try unplugging the power cable from the dashcam to see if it can turn off normally: If it can turn off normally, then the car's cigarette lighter socket still has voltage output (some car models have constant power at the cigarette lighter after the ignition is off, and it will only cut off power after locking the car for a while). You can wait five minutes after turning off and locking the car to see if it can turn off.
If the hardwire kit is powered, it is necessary to check whether the step-down cable is connected to the wrong fuse position (after the car is off, measure the fuse position connected to the ACC line of the step-down cable; if there is still voltage output, it indicates a wiring error). If the ACC line is connected to a constant power source, it will cause the dashcam not to turn off automatically after the car is off.
Malfunction due to faulty accessories: In the powered-off state, remove the memory card from the dashcam and unplug the middle or rear camera interface, then power on the device. Press the reset R hole (Reset) briefly or long until the device responds.
