The requirements for cameras that will work with the Equipment detection (PPE) module are shown in the following table.

Video stream from camera

  • The resolution is at least 640x360 pixels. It is also not recommended to use a resolution higher than 1920×1080, since higher resolution does not 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 3 for solving typical tasks.
  • Color image only
Lighting
  • Lighting in the scene is at least 200 lux per square meter. In conditions of insufficient or excessive lighting (night or light-striking), stable operation of the video analytics is not guaranteed.
  • There are no abrupt changes in lighting
Scene and camera angle
  • Moving objects are visually separable from each other.
  • The background is mostly static and does not change abruptly.
  • There are no products made of rods in the detection area.
  • Moving objects are minimally obscured by static objects in the scene (columns, trees, etc.).
  • The analyzed scene does not have reflective surfaces and sharp shadows from moving objects. If present, they should be masked.
  • Camera shake does not result in image offsets greater than 1% of the frame size

Object images

Objects image requirements for Equipment detection tool (PPE)


Correct operation of the detection tool is not guaranteed when using a fisheye lens.

For the detection tool to work correctly, you must position the camera in such a way that the person wearing the equipment can be seen in detail from this angle. We don’t recommend pointing the camera from the top downwards, because in this case the correct operation of the detection tool isn’t guaranteed.
