3.5 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 no
face is detected.
The number of faces counted is saved to GV-Web Report which can analyze counting data from
multiple GV-VMS systems. For details, see GV-Web Report User’s Manual.
3.5.1 Installing the Camera
1. Install the camera inside an entrance pointing 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.

2. Avoid installing the camera where it is subjected to direct sunlight or reflections. The lighting of
the entrance where you set the camera should be sufficient but not too bright or dark. Light
should be distributed evenly across faces without too much light coming from one side. Sharp
shadow edges in the camera view may affect the accuracy of face count.
Note:
1. Up to 16 cameras can be configured for this function.
2. The Face Count results are only available on GV-Web Report V2.2.6.0 or later.
