Does the car dash cam still work after the car is turned off?
2 Answers
Whether the car dash cam still works after the car is turned off depends on different situations: 1. If the dash cam is powered through the reading light, it will continue to work after the car is turned off; 2. If the dash cam is powered through other sources, it will not work after the car is turned off. The method to install a car dash cam is: 1. Use a clip to fix the dash cam near the car rearview mirror; 2. Open the interior panel and place the wire inside; 3. Insert the wire into the gap of the glove box; 4. Plug the other end of the wire into the cigarette lighter. The functions of a dash cam are: 1. To record the video and audio of the entire driving process, providing evidence for traffic accidents; 2. For car owners who enjoy road trips, it can record the scenery along the way.
Whether a dash cam works after the car is turned off depends primarily on its power supply. If it's plugged directly into the cigarette lighter, the dash cam will automatically shut down and stop working when the power is cut off after turning off the engine. However, if it's hardwired to the vehicle battery's constant power port or has its own built-in battery, it can continue operating after shutdown, especially in parking surveillance mode. For instance, it will activate video recording if someone scratches the car or causes a collision. I've used one with a built-in battery that could monitor the vehicle's surroundings for several hours after shutdown, which was quite convenient. However, keeping it on constantly drains the car battery and might make the next startup difficult, so I only enable the surveillance feature when parking in high-risk areas at night and turn it off during normal driving. Overall, whether it works or not entirely depends on the installation method and device features, and simple settings can address safety concerns.
