What Does the Motion Detection of a Dash Cam Mean?
2 Answers
The motion detection of a dash cam means that the dash cam will automatically start recording only when there is movement within its camera range, otherwise it will stop recording to save storage space. The installation method of the dash cam is as follows: 1. Use tools to fix the dash cam near the rearview mirror; 2. Pass the USB head from behind the glove box and tuck the wire into the back of the glove box; 3. Plug the other end of the power cord into the cigarette lighter. The functions of the dash cam are: 1. Record the video images and sounds of the entire driving process to provide evidence for traffic accidents; 2. Record the scenery along the way for self-driving car owners.
As someone who has been driving for many years, the motion detection feature of dash cams is quite practical for me. Simply put, it monitors movement in front of the camera when the car is parked. If it detects moving objects, such as passing pedestrians or approaching vehicles, it automatically starts recording video. I use it to monitor my car when parked in the neighborhood, and once it actually helped me capture footage of someone scratching my car door, avoiding any disputes. I don’t use it while driving, but enabling it after parking saves storage space since it only records key moments instead of running 24/7, preventing battery drain. I find the setup simple—there’s just a toggle in the dash cam menu, and you just need to turn it on. Overall, this feature enhances safety, acting like a dynamic sentry for the car, which is quite hassle-free.
