FPS is at least 12. For face recognition at turnstiles, FPS is at least 6
Camera must have lenses that don't produce significant distortion of the face, especially in the centre of the frame

Attention!
Correct operation
Correct operation of the detection tool has a strong dependence on the optical distortion of the lens. The less distortion in the frame, the higher the accuracy of the algorithms.

Lighting
Faces must be evenly illuminated with diffused light of at least 200 lux. Directional side lighting isn't allowed
Contrast of the captured faces must be over 64 grayscale
Insufficient or excessive lighting isn't allowed
There must be no backlighting and sharp gradients of light and shade
Scene and camera angle
Maximum angle of frontal perspective of the photos of people’s faces received from cameras must not exceed +/- 15°
Mutual faces overlapping must be minimal
We recommend using the centre of the frame for analysis, as this is the area where distortion of the face image is minimized

Note
You can specify the required distance between the camera and the face using a lens with the required focal length.
