How to track the movement of objects on a CCTV camera?

Question

Monitoring

There is a camera that is installed on the security booth, it is necessary to track the number of trucks passing in the surveillance zone of this camera.
We need some kind of program that will read the readings from the camera, and write to some kind of cache or file, exactly the number of passing cars. Does such software even exist? If not, what camera technology should I buy?

Answer 1

Can you see the license plate on the camera? If so, then this would be the easiest option.

Answer 2

There are direct license plate recognition modules. IMHO, all video surveillance brands have such solutions. 146% that secureos iss.ru has such a module and it seems that there was a count of wagons.
