Face Recongition

5.3 Ideal Camera Position

Face recognition works best when the camera is properly aligned with the face of the

recognition target. When installing the camera, make sure to take the relevant environmental

factors into account, such as height, distance, focus and range, to achieve optimal recognition

results. A well-lit hallway is an example of an ideal location, where the direction of movements

of the recognition targets can be easily predicted. Make sure you meet the criteria below when

installing the camera:

Less Ideal Installation Scenario Recommended Installation Scenario

A height of > 2 m or < 2 m An approximate height of 2 m

A distance of > 4 m or < 4 m An approximate distance of 4 m

Wide angle end Telephoto end

> 15° of lateral deviation < 15° of lateral deviation

Less Accuracy Better Accuracy

 Height & Distance: The more aligned the camera is to the front view of the face, the

better the recognition results. Mount the camera at a 15-degree angle to the face of the

recognition targets, or at a height of approximately 2 m (6.56 ft). The recognition result is

at its best at a distance of approximately 4 m (13.12 ft).
