Can a Dash Cam Continue Recording After the Vehicle is Turned Off?

[DeSteven]

If the dash cam is equipped with a parking monitoring function, it can continue recording after the vehicle is turned off, but the recording time is limited. Since the dash cam's power is supplied by the vehicle, it can only operate when the engine is running. Some dash cams have built-in batteries, but the capacity is too small to support prolonged operation. Connecting the dash cam directly to the car battery for extended periods can lead to excessive battery discharge, negatively impacting the battery's lifespan. Functions and Categories of Dash Cams: Function: A dash cam is a device that records video, audio, and other relevant information during vehicle operation. Once installed, it captures the entire driving process, providing crucial evidence in case of traffic accidents. Categories: Parking monitoring functions in dash cams are divided into two types: continuous recording or short-term recording triggered only when the vehicle detects vibrations. However, there are currently no dash cams capable of continuous long-term recording after the vehicle is turned off. Solutions for Parking Monitoring Power Supply: To enable parking monitoring, the dash cam must either have an internal rechargeable battery or be connected to the ACC fuse for power. After the vehicle is turned off, it automatically enters parking surveillance mode, where sensors continuously monitor the vehicle's status. If any abnormal activity or vibration is detected, the dash cam automatically records and stores the footage separately. Compared to a constant power connection, dash cams with parking monitoring connected to the ACC fuse consume less power and reduce battery drain. However, if the vehicle remains unused for several days, the battery may still deplete, making it difficult to start the engine. Another method is to use a power bank to supply electricity for parking monitoring. However, this approach has its drawbacks, primarily concerning the quality of the power bank. In high-temperature conditions, the power bank may overheat or even explode, potentially causing more significant damage.
