This post emphasizes an issue of being unable to activate Head Count on X3221-C. Please find the solution to it below.
Issue description
A customer stated that they were unable to activate the head count function on a X3221-C 2MP IR Fixed Dome Camera. When trying to enable the head counting algorithm, they receive a 'Disable the function first' message.

Handling process
I have checked the procedure on how to activate the Head Count function on the X3221-C and found that the following functions need to be disabled as a prerequisite for this function:
face detection;
parking detection;
license plate detection;
automatic tracking functions.
