At what height should a camera be fitted?
The lowest that keeps it out of arm's reach, and no higher. Every extra metre makes what you see of a person worse, because the camera ends up looking down at them and what gets recorded is the top of the head and the shoulders instead of the face. That is the most repeated mistake in the installations we find already built.
Heights go up for two legitimate reasons: vandalism, or having to clear an obstacle —parked lorries, a hedge, people themselves— to get a line of sight. When you have to go up, you make up for it by moving the camera back from the point of interest and closing in the lens: looking from far away and flat gives better faces than looking from close up and steeply down.
And there is one height that does not depend on the image but on maintenance: the one you can reach to clean and refocus without hiring a cherry picker. A camera you can only reach with machinery ends up being a camera nobody ever inspects, because the inspection costs more than the camera.

A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
