Camera | - Resolution: 720x576 pixels (CIF4), using ; the use of 360x288 pixels (CIF1) is acceptable; oversize images are reduces until reduced to CIF4.
- Fps: not less than 6at least six.
- Color: analytics works with both grey and color images.
- Camera must be rigidly fixed.shaking is absent
|
Lighting | - The best working of detection is archived detector operation is achieved at medium lighting. In conditions of insufficient (night) or excessive (exposurelight-striking) lighting, the quality of analytics can algorithm operation can be reduced.
- Sharp lighting changes of lighting can lead to the short-time invalid improper analytics working.operation
|
Scene and camera angle | - The best
position – - position—a camera "looks"
to - at the scene vertically down. The better you perform this requirement, the
carefully - more accurate the received estimation.
- Sizes of the camera field of view:
3x3m - 3x3 m is minimal (6x6 people),
4x4m - 4x4 m is optimal (8x8 people),
8x8m - and 8x8 m is maximal (16x16 people).
- Background is static and
is not - isn't changed sharply.
- Analytics can work
inappropriately - improperly on
specular - reflecting surfaces and in the case of sharp shadows from
moved - moving objects.
- Analytics can work
inappropriately in case of in the camera field of view - improperly if there are periodic movements of background objects (trees, working TV,
etc.).- and so on) in the camera field of view

Object imagesObjects image | - Image quality: the image
is to - must be clear, without visible defects from
reducing procedure- the compression algorithm.
- Permissible person size
of a person - (the area of a rectangular track around a person) as a percentage of the frame area: from 0.25% to 10%
