Video stream and scene requirements for the Equipment detection (PPE) module

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 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

• 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
