The camera technical specifications which are necessary for the correct operation of the Cognitec recognition module are listed in the table below:
Camera specifications | - Color camera with resolution: 2 million pixels (1080p), minimum: 720p;
- CCD / CMOS: 1/1.8 or higher;
- H.264 and RTSP support;
- The maximum encoding speed should be at least 4 Mbps;
- Guaranteed image quality in low light conditions;
- The frame rate should not be less than 12 FPS, and not less than 6 FPS for face recognition at turnstiles
|
Video image | - The sharpness of the captured faces on the received photos should not be less than 64 grayscale. Deficient or exceeding illumination is not allowed;
- There should be no back light and sharp gradients of light and shade;
- The faces should be evenly illuminated with a diffused light of at least 200 lux. Directional side lighting is not allowed;
- The photos of the captured faces received from video cameras should be clear. Image blurring caused by motion is not allowed;
- The maximum deviation of the face in the camera FOV from the face-forward position should not exceed 15 degrees;
- The distance between pupils on the received photos of the captured face should not be less than 96 pixels;
- There should be minimum mutual overshadowing of the captured faces
|
Camera positioning | - The required distance between the camera and the face can be set using a lens with the required focal length
