Got also an OEM looking Camera from AliExpress. Similar as the one above but "smaller" and cleaner look in my opinion. Installed it this weekend and works good. It is hooked up at the Rain sensor (not the mirror!). Clean look and for what I wanted to use it, it is OK. If you need to be able to always read the licence plate, then this is not the camera to go for especially in the dark. It also has Mic to record the sounds in the car.
Recording is done in 4k on a micro SD card. I set the video's to 5min (maximum) standard it is set to 1min. Settings are done using a wifi connection and an app.
It does not provide the parking mode. However. When you have a 530e and plug it in the charger. For the time it charges, the camera will work! I'm also certain that if you do splice the wires you can hook it up to a permanent voltage. Other buyers even offer this kit with the parking option.
