Guidelines for Cameras

Camera Positioning and Shooting​

To achive better tracking and detection results with Face SDK, please follow the recommendations below:

  1. Requirements for lighting in the recognition zone:
    • illuminance level in the recognition area should be at least 200 Lux (only when the camera is located at a distance of no more than 3 m from a face), the optimal value is from 300 to 500 Lux
    • avoid back light whenever possible
    • light should be diffused. Avoid harsh shadows on a face
  2. The camera should observe the face in a horizontal plane at an angle from 0 to 30 degrees, the optimum angle is from 0 to 15 degrees.
  3. The camera should observe the face in a vertical plane at an angle from 0 to 20 degrees, the optimum angle is from 0 to 15 degrees.
  4. It is recommended to place the camera at the face level.

We recommend to use Axis P1365MK ii or P1367 (for longer distances).
General recommendations for cameras are:

  1. 1080p (Full HD) resolution.
  2. Frame rate of at least 10 FPS.
  3. Suitable resolution and lens: the distance between the eyes of a face in the frame should be at least 30 pixels in the far field (for example, at the entrance) and at least 50 pixels in the near field (when a person already passes by the camera and leaves the frame).
  4. Function of adjusting the exposure and shutter speed to prevent blurry frames of people passing by.
  5. If a camera supports WDR, Backlight compensation, Highlight compensation, it is recommended to turn these functions off, otherwise the image can be blurry.
