Camera

• Resolution should be at least 640x480 pixels.
• Fps: not less than 6.
• Color: analytics works with grey and color images.
• Camera shaking should not result in image offsets greater than 1% of the frame size.

Lighting

• Medium lighting. In conditions of insufficient (night) or excessive (exposure) lighting, the quality of analytics can be reduced.
• No sharp changes of lighting.

Scene and camera angle

• Camera is to be directed in the line of the railway or as close to it as possible.
• Background is mostly static and is not changed sharply.

Objects image

• At the time the detector was started, there was no train in FoV.
• Minimum overlapping of moving objects with the static objects in the scene (columns, trees, etc.).
• Analytics may not work correctly on reflective surfaces and if there are sharp shadows from moving objects.
• The width and height of objects in the image should not exceed 75% of the frame size.
• The speed of objects in the image should not be less than 1 pixel per second.
