What cameras (or NVR) would you recommend for a people counting system?

Question

CCTV

Hello! Recently, I faced the task of installing a visitor counting system at the exhibition, which would count the number of incoming and outgoing visitors. At first I decided to use cameras and NVR from UBIQUITI, but broke off (this function seems to be missing.) Recommend pzhl. equipment and solutions for this task. T.K. Since this is a temporary exhibition, then the solutions are preferably not expensive. And is there a WIFI camera to solve this problem?

Counting visitors by video
In general, the task is quite simple, but IMHO sensors at the entrance and exit will be more effective.
