Camera requirements for the Crowd detection (TVN) module are given in the table.

Camera:
  • Resolution: 265x256 pixels and higher

Lighting:

  • The best detection tool performance is achieved under good lighting: no flash, with even lighting, in normal weather conditions (no rain). In conditions of insufficient lighting (for example, at night), the quality of algorithm performance may decrease.
  • Analytics may not work correctly with light and shade variations on objects: homogeneous lighting is recommended, without complex light-refracting forms

Scene and camera angle:
  • Analytics may not work correctly if the scene is a repeating pattern (e.g., a crosswalk and a cart on it).
  • Analytics may not work correctly when recording a close-up view with only one face in it
Object images:
  • Analytics may not work correctly if there are objects that look like people (monuments, animals) in the camera FOV
