Should the Motion Detection While Driving Be Turned On?

Generally, the motion detection function while driving should be turned on because it does not consume much power and provides good vehicle protection when the owner is not present. The motion detection function in a dash cam is similar to parking surveillance. When the vehicle is turned off and stationary, it relies on the dash cam's own power or the car battery to operate. While the motion detection function is active, the dash cam remains powered on but does not record footage. It only starts recording and saves the footage to the dash cam's hard drive when the vehicle body shakes or there is a change in the dash cam's field of view. This effectively prevents situations where the vehicle is scratched by external objects without the owner being able to find evidence.
I think the driving motion detection feature should be kept on in most situations. Having driven for ten years myself, I've always kept it activated, especially when parking in the city or during traffic jams. It automatically starts recording if there's suspicious movement around, helping document collisions or theft attempts. In case of an accident, the video evidence is extremely useful—I once relied on it to settle an insurance claim. However, be aware that it consumes more battery, particularly in older vehicles, which may risk draining the battery when parked. I recommend investing in a good dash cam with auto power-off protection and regularly clearing the memory card to prevent it from filling up. Overall, it adds an extra layer of security without being cumbersome to operate—just make it a habit. The peace of mind when driving is worth the minor maintenance effort for that added protection.
