Generally, the dash cam stops working after the car is parked, but a small number of dash cams continue to operate. Here is the relevant information: 1. Whether the dash cam works depends on which power line it is connected to. Some built-in dash cams in certain car models are connected to a constant power source, in which case they will not automatically shut off and can record 24 hours a day; if connected to the ACC, they will automatically shut off when the engine is turned off. 2. A dash cam is a device that records images, sounds, and other related information during vehicle travel. After installation, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents. For those who enjoy road trips, it can also be used to document the process of conquering difficult and dangerous routes.

Whether most dash cams can record when the car is parked depends on the model and settings. What I commonly see is that basic models automatically stop working after the engine is turned off, only recording while driving, as they lack continuous power supply. However, high-end models or those with specialized features support parking surveillance, which requires either a built-in battery or connection to the car's backup power. They rely on motion sensors to detect activity around the vehicle and trigger recording. For example, once my car was scratched, and luckily the dash cam was in parking mode, capturing the evidence. I recommend checking the manual to see if this feature is supported; if not, it can only protect against accidents while driving. During installation, it's best to connect to a constant power circuit to ensure stable power supply.

I've been driving for years and have encountered recording issues when parking multiple times. My dashcam usually only records when the car is started and goes into sleep mode when parked, unless a special mode is set. Some battery-powered versions can last for a few hours, automatically activating when detecting collisions or movements. However, most basic models don't have this feature, which saves money but also has limitations. For safety, I recommend choosing one with parking monitoring—it's simple to install and gives peace of mind.

From a safety perspective, I always emphasize the necessity of dashcam parking recording. The risks don't diminish when the car is parked - parking lot collisions or thefts occur frequently. If the device isn't in parking mode, you might miss crucial moments. I recommend using the motion detection function to keep it alert; proper setup can protect your vehicle during parking. But be mindful of battery consumption to avoid draining it.
