3.8 Face Count
The Face Count function allows you to count the number of faces that appear in the image. You can
also select to invoke a computer alarm or trigger an output device when a face is detected or when the
system is unable to detect a face.
The number of faces counted is saved to the GV-Web Report, and the GV-Web Report can analyze
counting data from multiple GV-Systems. For details, see GV-Web Report User’s Manual.
3.8.1 Installing the Camera
1. Install the camera inside an entrance pointing horizontally outward. The Face Count function is
designed to detect front-view faces only, and the area of the detected face must take up 10% to
50% of the live image.
Figure 3-29
2. Avoid installing the camera where it can be subjected to direct sunlight or reflections. The lighting
of the entrance where you set the camera should be sufficient but not be too bright or dark. Light
should be distributed evenly across faces without too much light coming from one side. If sharp
shadow edges are visible in the camera view, the count accuracy might be less than what it
normally is.
Note: This function is only available when an AVP dongle is used. Up to 16 cameras can be
configured for this function.
