Can the dash cam still record when the car is parked?

If the dash cam has a parking monitoring function, it can continue recording after the vehicle is turned off. However, the recording time is not long because the dash cam is not charging when the vehicle is off. Here is some information about dash cams: The parking monitoring function of dash cams can be divided into two types: 1. Full-time recording. 2. Short-time recording only when the vehicle vibrates. Additional information: The dash cam operates using the car's power during the day. When the vehicle is turned off, the dash cam stops working. Although many dash cams have built-in batteries, some batteries can only last for four or five hours on standby, while others may only last for about half an hour. Therefore, dash cams generally cannot continue recording for a long time after the vehicle is turned off.
I've always enjoyed researching this. My dash cam continues recording after parking because I specifically went to a modification shop to have a voltage reduction cable installed, directly connected to the battery. This way, after turning off the engine, the dash cam enters parking surveillance mode, and as soon as someone touches the car, the G-sensor triggers and starts recording key footage. However, it's important to monitor the battery level—I've set a low-voltage protection at 11.8V to avoid draining the battery and being unable to start the car. If the car won't be used for a long time, it's best to unplug it or choose the time-lapse recording feature, which only records one frame per second, saving both power and memory card space.
In my opinion, the key lies in the wiring. Regular cigarette lighter power supply cuts off when the car is turned off. However, using a step-down cable to connect to a constant power circuit enables 24-hour monitoring. When I installed it, I specifically chose a model with collision detection function and checked the parking guard mode in the settings. Last time in a mall parking lot, it recorded the other party's license plate when my car was scratched. But you need to calculate the battery capacity carefully. For older cars, it's best to install solar auxiliary power supply or capacitor energy storage devices to avoid battery drain.
