Ring Dash Cam

I bought the dash cam because my vehicle has been a target of retaliation. According to Ring it’s supposed to monitor parked vehicles too. I also liked the fact that it was easy to install. The dash cam shuts off about an hour after I park. What is the point of having this dash cam if it doesn’t do what it’s suppose to do?… and it costs $250. It’s not worth it to me if it doesn’t function like Ring says it does…. I might as well return this & get another brand that I can hard wire to my battery.
