Requirements to video parameters while working with detection tools and Tracker

• Resolution:
  • at least 640x480 but no more than 800x600 pixels for smart video detection tools
  • at least 320x240 pixels for other video detection tools
• FPS:
  • at least 6 frames per second for smart video detection tools
  • at least 1 frame per second for other video detection tools
• Video analytics works with both black-and-white and color images
• Camera shaking must not cause image shifting of more than 1% of the frame size

• Moderate lighting. Insufficient or excessive lighting (night or bright sunlight) may impact the quality of video analytics
• No abrupt changes in lighting

• 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, industrial products, and so on)
• Reflective surfaces and harsh shadows from moving objects can affect the quality of analytics
• Long single-color objects may not be tracked properly

Object images for smart video detection tools

• An object must be visible on the image
• There is no noise on the video image and there are no artifacts caused by the compression algorithm
• The width and height of objects in the video should not be less than 1% of the frame size (at resolutions not less than 1920x1080 pixels) or 15 pixels (at lower resolutions)
• The width and height of objects in the video should not be more than 75% of the frame size
• It is recommended that the linear measurements of objects in the frame do not exceed 75% of the frame size
• The speed of objects in the frame must be at least 1 pixel per second

• The object is to be visible at not less than 8 frames

• Within two adjacent frames the object cannot move in the movement direction for the distance that is longer than its size

• Quantity of simultaneously tracked objects on a frame—no more than 25
