Scrapped license plate

[Hanszl2001]

After my front license plate was dented twice in 1 week in a parking lot by an idiot driver with a tow bar, I'm st thinking about a shock sensor addition for the standard alarm system. Does anyone here on this forum have experience installing similar like this?

Yes -  a dash cam with parking mode feature would do the job,  probably better than trying to fit a sensor that trips your car alarm.   The dash cam will capture a picture of the culprit.

There is a lot of information on the internet about the pros and cons of different dash cams and parking mode options,  but some good basic info is at

With an alarm shock sensor you might get lots of false alarms.  It can be difficult to set the sensitivity level where it will pick up a tow ball strike  without also  activating in High winds ,vibrations from heavy trucks    ,even heavy rain drumming on the roof.     All these happened with the last car I had with a shock sensor.  It also had quite a high parasitic drain on the car battery when active   24/7  .   .In the end I disabled the  shock sensor function, leaving just the  basic alarm functions.

The damage will already be done.  Unless you are near enough to rush over and catch the person if the alarm activates  it also relies on them realising they caused the alarm and damaged your car.  And being honest enough to contact you. 

At least dash cam parking mode may give you evidence.

Ive been contemplating purchasing a parking activated dashcam such as the "Blackvue" which can be purchased with a seperate back up battery to protect the car battery.(Not cheap though),after i've just forked out almost 1k.for a rear bumper hit and run in a car park.🤬
