Need reco for car dashcam which has good motion sensor

[villageidiotY2K]

Hello ladies and gentlemen, as the title, can pls reco some good quality ones. 

My focus is on the parking surveillance and would like to record only when there's a motion. Not gravity sensor. 

 

I have previously used the 600thb dash cam with power bank for night parking but vdo quality and function is sh it. 

 

Im assuming it's better to get power from car battery for parking surveillance, anyone with experience enlighten me with cost and any problems and recommendations such as battery drainage, not being able to capture cause video is only caputing front of the car etc...
