| Camera | - Resolution must be at least 640x360 pixels. We also don't recommend using a resolution higher than 1920×1080, since higher resolution doesn't increase the detection quality, but significantly increases the consumption of resources. The optimal resolution for solving typical tasks is 1280x720
- The frame rate per second in the video stream from the camera is at least 8
- Color image only

| - Correct operation of the Pose Detection tools isn't guaranteed when using fisheye cameras and other cameras with strong image distortion.
- The camera tilt angle from top to bottom on a person must not exceed 30°. Otherwise, the detection tool won't operate correctly.
The following diagrams show the examples of:- The acceptable tilt angle:
 - The unacceptable tilt angle:

| Lighting | - Lighting in the scene is at least 50 lux per square meter. In conditions of insufficient or excessive lighting (night or light-striking), stable operation of the analytics isn't guaranteed
- No abrupt changes in lighting
|
| Scene and camera angle |
- Moving objects are visually separable from each other
- The background is mostly static and doesn't change abruptly
- Moving objects are minimally obscured by static objects in the scene (columns, trees, and so on)
- The analyzed scene doesn't have reflective surfaces and sharp shadows from moving objects. If present, they must be masked
- Camera shake doesn't result in image offsets greater than 1% of the frame size
- For the correct operation of the Sitting Person Detection and Person Down Detection sub-tools, the area of interest must be covered from at least two perpendicular angles (a and b are the directional beams from the cameras and the point of their intersection is the area of interest):
 Image Added
The algorithms have a limitation and won't work correctly if:
- a person falls down or sits down with their head or face towards the camera,
- a person falls down with their feet towards the camera (for the Person Down Detection sub-tool)
