BroNote T7838WIP LENS is 3.6mm. May not be wide enuff. Perhaps install an actual all round car surveillance camera from car workshop may cost you lesser in overall cost.
I've done a testing for marix using their battery pack on T7892WIP. It lasted a whopping near 13hrs. But for T7838WIP, it didn't last up to 11 hrs. For 32gb microsd card, recording is more than enuff.
Note that anything that happens, you will surely retrieve the clips within 24hrs.
Tks geckosg. Will drop by Marin later to check it out.
