Hi sifus, which of these cam is the latest and better quality among Xiaomi dash cam ?

Hi, i just got my cam. i was wondering how to seperate the dashcam with the electrostatic film. i was trying to tear it off but i notice the sticker which attached to the cam is completely stuck to the film and might peel off from the cam and i stop. is it supposed to be like that?

Is it okay for the dashcam to get very hot under the weather. I mean is it designed to take such heat in malaysia ?

If the battery spoil, I can remove it and it will still work as usual when I power up my car right ? Or the battery will somehow fuse the entire cam
