For each type of situation analysis detection tool you can set a detection zone. 

After creating a detection tool,  its rectangular detection zone is displayed in a bright color. If you have set privacy masks, they are grayed out (see Tworzenie stref dla Analizy Sceny).

Configuration of the detection zone is carried out in the same way as for general zones for scene analysis (see Tworzenie stref dla Analizy Sceny).
