Dashcam installation, where to go?

Hi folks,

after reading a lot about the traffic situation I decided to get a dashcam for my wifes car. It is a 70mai cam. Can anyone give me an advice where to go? Dubai/Sharjah?! The car is a BYD SONG. I would prefer to have it properly installed to the battery, but if thats a hassle, then just installation and working while driving is ok, just don‘t want cables hanging around. Front and back camera.

THX.
