Rules
What are Rules?
Rules can be set for each camera. They are used to define:
l
The types of objects the camera should monitor.
l
The regions, objects, and directions of travel the camera should monitor.
l
The actions a camera should take when a rule is triggered.
When a rule is triggered, it results in an alarm event. You can view the rules on each camera and their details,
such as the name of the rule, whether or not the rule is enabled, and the action taken when the rule is triggered.
NOTE: Unless your account has been granted permission, you cannot create, edit, or delete rules.
Regions of Interest, Regions of Disinterest, and Beams
A rule can use Regions of Interest (ROI), Regions of Disinterest (ROD), and Beams to determine what will cause an
alarm event to trigger.
l
Regions of Interest: The areas of a scene where activity is detected.
l
Regions of Disinterest: Used to mark areas within an ROI where false alarms occur frequently. Areas
marked as a ROD will not trigger an alarm when the activity detected in the ROI normally would.
l
Beams: Virtual lines used to detect when an object crosses a specified beam, such as a person walking
through a gate.
If a rule contains an ROI or Beam, it will be marked on the camera window thumbnail in the rule summary. To
access a rule summary, complete the steps in Viewing Rules below.
NOTE: Regions of Disinterest will not be marked unless it is enabled in Preferences. To do so, complete the
steps in Enabling Regions of Disinterest (ROD) in Thumbnails on page 27.
