NOTE
Accuracy of Person and Vehicle detection will be influenced by multiple factors, such as the object’s distance
from the camera, the size of the object, and the height and angle of the camera. Night vision will also impact the
accuracy of detection.
5.3 Optimizing Face Detection Accuracy
The following are important camera installation notes to ensure accurate Face Detection. For full
camera mounting instructions, see your camera’s documentation at lorex.com.
• Install in a bright area and avoid facing direct sunlight with strong backlights and dark
shadows.
• Choose a location where objects of interest will be no further than 15ft (4.5m) from the
camera.
• Position the camera 10ft (3m) off the ground to detect the full proportion of a face.
• Angle the camera around 15° down from the level position.
• Point the camera directly where objects of interest will be facing.
High Accuracy Face Detection 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 cap-
tured. 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.
NOTE
• Face Detection is compatible with certain Lorex DVR’s only. For a list of compatible DVR’s please visit
