Not really, our technology is not suited for such an application. People in a queue don’t necessarily look towards the camera when they arrive in the queue, and will not be tracked during all their waiting time when they stop looking at the camera. It is thus impossible to determine the waiting time correctly.    


Using VidiGates to count the number of people in a line might also give erroneous numbers. People being so close from each other, 2 might be counted as 1. And in places where people have caddies, the caddies might be counted as a person.   
To our knowledge, the only viable solutions for such applications are: Thermal cameras that count the number of heads (like Irisys), and specific algorithms for the computation of pixel density in well defined areas that infer a number of people. Eg.
