What is the difference between cam v4 and cam OG?

I can see it useful on computer monitor or a TV screen, but not on a phone with limited screen real-estate.

My car is also old (2016) pre CarPlay so I bought a Bluetooth CarPlay/AndroidAuto screen. It’s all Siri enabled no need to take my hands of the wheel. Thank God, Wyze is not compatible with it :grin:
