Camera Recommendations

For video identification and video analytics, you are recommended to use cameras with a resolution of 1920x1080 @30fps and support for H.265/H.264 video compression.

General Recommendations​

  • 1920x1080p (Full HD) resolution;
  • Frame rate of at least 10 fps;
  • 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);
  • Function of adjusting the exposure and shutter speed to prevent blurry frames of people passing by;
  • If a camera supports WDR, Backlight compensation, Highlight compensation, it is recommended to turn these functions off, otherwise the image can be blurry.

Camera Positioning and Shooting​

  • The lighting must be sufficient for the camera to produce a clear image. The optimal value is from 300-500 lux (standard office lighting);
  • Avoid back light whenever possible;
  • Light should be diffused. Avoid harsh shadows on a face;
  • It is recommended to place the camera at the face level;
  • 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 (see Fig. 1);
  • 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 (see Fig. 1).
