Requirements for the operation of the Pose Detection and its sub-tools are given in the table:
| 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
|
| Object images | - The detected object must be clearly distinguishable by the human eye
- The detected object must be completely within the frame
- The image isn't noisy and not distorted by the artifacts of compression algorithm
- The duration of the object visibility is at least two frames
- The minimum value of pixel density per meter is observed:
| Image resolution | Object type | Minimum pixel density per meter (ratio of the object width in pixels to the object width in meters) | Minimum object size in pixels, width x height |
