Car Camera that works with sunshade when parked and works on rechargeable battery

I want a car camera that records when parked and not when driving unless activated. In the summer I put a sunshade in my windshield, and that makes the current car cam no good for protection when parked unless someone breaks into the car. I don't want to record while driving and only want to turn on recording when I am in the car if pulled over by a cop. I don't like the idea of connecting the cam to my car because I don't trust that it isn't collecting data. how about a camera that works on a rechargeable battery just like I can do with stick up cams and doorbell? And that protects against vandalism or break ins? Just a camera for use when parked and that can be manually turned on when driving, so a battery like other cams would work fine. give us the option. plus how do I put my sun shade up and have a car cam do me any good when parked unless someone breaks in?
