Generally, dash cams do not record after the car is turned off. However, some dash cams can be specifically set to continue recording after parking. This feature is called parking monitoring or sometimes referred to as away-from-car recording. It allows the dash cam to keep working even after the engine is shut off. A dash cam is a device that records images, sounds, and other related information during vehicle operation. After installation, it can record the entire driving process, including video and audio, which can serve as evidence in traffic accidents. It also documents the time, speed, and location during the drive. For those who enjoy road trips, it can be used to record the journey through challenging terrains.

I've used quite a few dash cams in my car. Usually, they turn off after the engine is shut down because they're plugged into the cigarette lighter, and once the power is cut, they stop recording. But one day, my car got scratched while parked on the roadside, and the dash cam didn't capture it. That's when I learned some models have built-in batteries or can be connected to a constant power source, allowing them to keep working after parking. Later, I switched to one with parking monitoring, specifically set to the engine-off detection mode—it starts recording whenever someone approaches and doesn't consume much power normally. However, long-term use of parking mode might drain the battery. Last time, I almost couldn't start the car and had to check the battery health periodically. I recommend clarifying the power supply method when installing a dash cam—don't be as careless as I was initially. Remember, safety comes first. Being able to monitor thieves or accidents even when parked is worth the investment.

As an electronics enthusiast, I've found that whether a dashcam records after the engine is off depends on its power supply method: if it's connected to the cigarette lighter socket, it stops when the car is turned off; but if connected to the OBD port or directly to the battery via a constant power line, it can continue monitoring. Many newer dashcams support parking mode, which utilizes a built-in small battery or standby function to start recording only when motion is detected, making it both energy-efficient and practical. Installing a fuse kit can easily handle the wiring, but be careful not to drain the battery—remember to drive the car periodically to recharge it. I recommend choosing a product with power-off protection, which is safe, durable, and hassle-free for parking recording. Just do some simple setup adjustments and you're good to go.

I must say, whether the dash cam can record after the engine is off depends on whether you've enabled parking surveillance. If not set up properly, it usually shuts down. This feature is quite important, especially in residential areas or parking lots, as it can capture scratches or theft attempts, protecting your car's safety. I've had a friend whose car got scratched, and the post-shutdown footage helped identify the culprit. Remember to check the parking mode option in the dash cam's menu; models with battery versions are easier to activate. But don't be careless—keeping it on continuously will drain the battery, so turn it off when appropriate or select a low-power mode. Ensure safety by reviewing the footage promptly.

From a cost-saving perspective, a dashcam that continues recording after the engine is turned off may drain the car battery, especially with low-end models that can deplete the battery overnight, leading to starting difficulties. I've personally experienced this several times and had to spend a considerable amount on new batteries. Currently, I use a standard cigarette lighter-powered model that turns off when the engine is shut down, avoiding additional power consumption. However, if parking surveillance is needed, it's advisable to opt for a low-power version or one with power-cut protection, configured to record only short events. This way, it records while saving power. Developing a habit of manually turning off the dashcam before shutting off the engine or checking the battery status to avoid unexpected expenses is both practical and reassuring.
