2. Optimizing face and mask detection accuracy
High accuracy Vs. low accuracy face detection
Accuracy will be influenced by lighting conditions and the distance/angle of a person's face to the
camera. To distinguish facial features, the camera must be positioned head on with a clear view
of a person's face. Obscured and partially/fully covered faces will not be accurately captured.
To improve the range of face detection in low light conditions, color night vision will switch to
black & white. If you cannot meet these requirements for installation, it may be best to follow the
guidelines for person and vehicle detection instead.
