Door ding evidence

Door dings are small damage. The missing proof is usually the expensive part.

A door ding can happen in seconds and leave no note. Parking Guard helps a spare smartphone watch the risky side of your parked car and save evidence around the moment of contact.

Why door dings are hard to prove

A door ding or shopping cart mark often happens while you are away for a short errand. By the time you return, the other person is gone and the damage is already there.

Parking Guard is designed for this narrow evidence problem. It is not a full security system; it is a way to make short parking sessions more observable with a phone you already own.

What to record

The best angle is usually through the side window, looking toward the neighboring parking space, cart path, or door swing area. A wider lens can help if your phone supports it.

For door dings, enable motion and sound together. Add impact detection if the phone is mounted firmly enough to sense contact or vibration through the vehicle.

  • Use motion for people, carts, bikes, and adjacent vehicles.
  • Use sound for contact noises or voices near the car.
  • Use impact for jolts, door hits, or body contact that reaches the phone.

What happens after detection

Parking Guard saves a clip with video before the trigger and your selected recording duration after it. Events stay available offline in the app, so you can review the footage in the parking lot before deciding what to do.

You can save evidence to Photos, keep it in the app, or enable optional Google Drive backup so the files are copied to your own Drive account.

Use it honestly

Always follow local recording laws and property rules. Avoid placing a phone where it blocks visibility, interferes with airbags, or attracts theft risk.

The app helps preserve evidence, but you still need a usable camera angle, enough battery, and enough storage for the session.

FAQ

Questions before using Parking Guard for this situation.

Short answers, with the same limits the app shows in its main product page.

Can Parking Guard detect a door ding?

It can react to motion, sound, or impact around a door-ding event, depending on angle, sensitivity, and how the phone is placed.

Should I use the wide-angle lens?

If your phone supports wide-angle recording, it can help cover the side of the car and the neighboring parking space.

Does it make a shutter sound when saving the still frame?

Parking Guard extracts a still frame from recorded video rather than using the standard photo shutter capture path.
