Dashcam recommendation and installation

Hello to the forum Now in the last 5 years my parked car has been hit for the third time and then ran away. I decided to buy a Dashcam now. I have never had a Dashcam and I don’t know about the topic either. I don’t need anything expensive, not a very good picture quality, it just has to be recognizable and identifiable the next time the culprit or the license plate. However, the camera must have a 360 degree angle. n, because all angles have to be covered, because my car has also been hit several times sideways. And of course the camera has to continue running with the motor switched off and have to record at least the last 24 hours. I calculate with approx. 150 Euro for the camera and for the installation I have to hire either a private person or a workshop. How exactly the camera is connected depends on the vehicle. I have a Mercedes CLA 45 C117. Would I be over recommending Greetings
