Proximity Rule

Introduction

The Proximity Rule wizard will create a rule that detects if a target gets within a specified distance of another target within the selected area. It also checks for the selected classification. If the rule is broken then an alarm will be raised and a camera tasked to follow the target.

Configuring the Wizard

  3. A New Area has been selected. This will automatically create a new area entitled “New Area” under the folder Areas in the configuration tree. This area can be edited and moved once the wizard has been completed.

  4. On the second page of the Wizard, you can configure additional properties. By default, the settings below are configured. These settings can be amended at a later date by editing the rule.

Actions

Alarm https://navtechradar.atlassian.net/wiki/spaces/TUN/pages/1874854150/Rule+Actions#Alarm

This will sound an alarm if the Proximity area is is approached. The Priority and Severity of the alarm can also be configured; for example, in a highly sensitive area then you may want the highest threat level to be set. By default it is set to Medium Threat.
