Video stream and scene requirements for the Tampering detector

Requirements for the operation of the Tampering detector are given in the table:

Object images
  • Image isn't noisy and not distorted by the artifacts of the compression algorithm
  • The width and height of objects in the image must not:
    • be less than 1% of the frame size (at resolutions of at least 1920x1080 pixels) or 15 pixels (at lower resolutions)
    • exceed 75% of the frame size
  • Speed of object movement in the image must be at least one pixel per second
  • To detect an object, the duration of its visibility must be at least eight frames
  • Between two frames, an object must move in the direction of a distance not exceeding its size. This condition is necessary for the correct calculation of an object track


  • No labels
