Car Dashcam Viofo A119 V3 buffer parking mode not recording

[villageidiotY2K]

Hi folks, I got this dash cam because I heard good news about buffered parking mode. (records 10 seconds previous to motion detection)

 

It seems to work well until some period it seems not to work. As attached pic, during 12:40 to 6:19AM theres no motion capure which is impossible since theres heaps of car rolling at midnight onwards.

 

My power source is frm OBD port with continuos power supply.

 

Any of you folks use this brand and can share setting to solve this problem?

I so wanna catch the vandals and smoke em ????
