Nextbase offers this as a feature called Intelligent Intelligent Parking Mode. In this mode, Nextbase dash cams with this feature (like the Nextbase 622GW) can use its internal battery to detect any knock to your car for more than a week, according to Nextbase, so you don’t need to drain the car's battery or hardwire the dash camera to use this function. However, with that said, you'll pay a premium for a Nextbase and you haven't mentioned a budget.
