Camera Installation Requirements

The solution is compatible with all cameras, that return the RTSP stream.

·      Quality: the highest

·      Bit rate: maximum possible

·      Profile: the highest possible

·      Stream smoothing: off

·      Exposure and brightness: such that for a given scene the face is clearly visible (if the camera is aimed at a light source, then an overexposed background is allowed)

·      Shutter speed: don't set too slow (more than 1/50), because in this case, the effect of blurring moving objects appears

·      Standard camera placement - ensure constant and steady illumination of recognized faces at the entrance or in the doors at face level or at a slight angle

·      Camera position: the face in the frame should be directed as straight as possible into the lens (optimal - at head level; means not from above, below, or from the side)

·      There should be no strong light sources from the side, above and below, creating harsh shadows and changes in light in different parts of the face

·      The camera should be well fixed and not shaking

·      Prevent refocusing and image sharpness changes

·      There should be no overexposures and glare in the frame
