If you're wondering whether dashcams work when your car is parked, the answer is yes - but there are a few things to keep in mind. First, most dashcams will only start recording when they detect motion or impact, so if your car is parked and nothing happens, there probably won't be any footage. Second, many dashcams have built-in battery backups that allow them to continue recording for a short period of time after the engine is turned off, but this may not be long enough to capture an event that occurs while your car is parked. And finally, some dashcams come with features like time-lapse mode that can be used to record extended periods of time (like overnight) even when your car is parked and turned off.
