The Cam needs to be authorized every time after power cable is plug out or power button is off.
If firstly authorized then needs to be at least connected with phone via wifi otherwise blue light is blinking and sayng"pls. authorize" After wifi connection and phone app launching it starts to record.
Battery is ok - recording without powering works
Memory?! - all setup is forgotten after power off
It looks that some internal memory which should remember the setup and authorization doesn't work! Do the phone conecting again and again before car driving is stupid.
