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.
