Face Detection is compatible with certain Lorex IP cameras. For a complete list of compatible cameras, navigate to your recorder series at .

16.1  Ensuring Face & Mask 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 .
Minimum Distance
Maximum Distance
8.2ft (2.5m)
2.8ft (0.86m)
10.4ft (3.19m)
9.8ft (3m)
4.5ft (1.39m)
9.9ft (3.02m)
11.5ft (3.5m)
6.3ft (1.93m)
9ft (2.75m)
  • 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 10.4ft (3.19m) from the camera.
  • Position the camera about 9.8ft (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 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.
Mask Detection
From the Face Detection tab, set the Alarm Type to Mask Detect. Using mask detection, a person improperly wearing or not wearing a face mask will be captured in the side preview panel and a notification will be sent from the Lorex Home app. Check Auto Response to remind visitors to: "Please wear your face mask."
