Hello guys

I own many tapo devices, one of them being the C500 camera. I am the owner of a car wash and i have a huge interest in counting how much car traffic i have in my car wash.

I tried to play around with the Tapo App and checked the motion detection feature of the C500 camera but there seems to be no way for me to actually detect cars because it only allows me to detect motion or persons. Is there another camera available that will help me achieve such thing? 

Also it's very important for me to differentiate between cars and trucks(lorries).

Any advice is welcome

Thank you
