You can set detection zones and/or masks which are common to all situation analysis detection tools.
Note 1: Common zones are analyzed and common masks are ignored by all situation analysis detection tools.
Note 2: Common detection masks allow you to immediately exclude from analysis those areas of a video camera's field of view which are known to be complex (leaves, water, etc.).
To set common detection zones and/or masks, you must perform the following steps:

  1. In the Detection Tools list, highlight a Situation analysis object (1) which offers a means of analyzing the situation in the field of view of the required video camera.

  1. In the viewing tile (2) set the nodes of the closed area, in order, inside or outside of which you want to create a detection zone or mask.

Note: When the area is being constructed, the nodes are connected by a two-color dotted line which outlines the area's borders.
