Requirements for the operation of the Abandoned object detector VI are given in the table:
| Object images | - For abandoned objects, the optimum density is 100 pixels per meter
- Maximum signal-to-noise ratio (without the function of automatic signal amplification) is at least 42 dB
- Image isn't noisy and isn't distorted by artifacts of the compression algorithm
- Distortion is no more than 10% (at the edges of the frame—at a distance of one third from its center in width, height and diagonal)
