The requirements for cameras that will when you work with the the Equipment detection (PPE) module are shown given in the following table.
Video stream from camera | - The resolution is at least 640x360 pixels.
|
It is also not recommended to use - We also don't recommend using a resolution higher than 1920×1080, since higher resolution
|
does not - 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 3 - three for solving typical tasks.
|
Color image only- Detector-based analytics works only with color images
|
| Lighting | - Lighting in the scene is at least 200 lux
|
per square meter- . The detector is applicable in conditions of artificiallight. In conditions of insufficient or excessive lighting (night or light-striking), stable
|
operation of the video analytics is not - analytics operation isn't guaranteed.
- There are no abrupt changes in lighting
|
| Scene and camera angle | - Moving objects are visually separable from each other on an image.
- The background is mostly static and
|
does not - doesn't 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.- manufactured goods, and so on).
- The analyzed scene
|
does - must not have reflective surfaces
|
and sharp shadows from moving objects should - must be masked.
- Camera shake
|
does - must not result in image offsets greater than 1% of the frame size

Correct operation of the detection tool isnWe don't guaranteed guarantee the correct detector operation if you use a the fisheye lens. For the detection tool detector to work correctly, you must position the a camera in such a way that the person wearing the equipment can be seen in detail with equipment is clearly seen from this angle. We don’t recommend pointing the a camera from the top downwardsto bottom, because in this case the correct operation of the detection tool detector isn’t guaranteed. Correct The correct operation of the Equipment detection (PPE) equipment detector isn't guaranteed if you use a the video stream or frames that were masked before they got into into Axxon PSIM by an the IP camera or similar means and methods. |
