Procedure 91 Creating a Video Intelligence alert
Step Action
1 Select Setup on the Web User Interface banner to display the setup menus.
2 Select Analytics from the Events and Actions menu.
3 Select the Video Intelligence tab.
4 Select the Enable Video Intelligence check box to enable Video Intelligence on the
camera.
5 Select the New Rule button.
6 Type a Rule Name for your rule definition in the field provided.
7 Select a fault action from the Action drop-down menu.
This fault action is activated when the parameters of the analytics rule are met.
8 Select a rule type from the Rule Type drop-down menu:
a Object Detection - Used to detect people or objects moving into a region of interest.
This alarm is similar to a motion alarm, but only detects people or objects the first time
they enter the region of interest. A separate event is generated for each object that
enters the region, even if the objects move into the region at the same time, unlike
motion detection that generates one event.
b Abandoned / Removed - (Video Intelligence only) Used to find changes to the back-
ground of a scene in a region of interest, for example, use it to detect when a stationary
object was placed, moved or removed. Draw the region of interest that contains all of
the area you want to search for changes.
c Direction - Used to detect objects moving in a certain direction through a region of
interest, for example, a car traveling the wrong way on a road. It is best to use a thin
region of interest to detect the direction of an object.
d Linger - Used to detect objects loitering in a region of interest. An object is lingering if it
remains in the region of interest. The minimum amount of time an object must linger
before being included in the results can be defined and you can draw a region in the area
where you want to detect objects lingering. Use a higher Overlap setting to avoid detect-
ing objects lingering nearby.
e Dwell: Used to detect objects lagging or tarrying in a region of interest. An object is
dwelling if it is mostly stationary. The minimum amount of time an object must dwell
before being included in the results can be defined. Draw a region in the area where you
want to detect objects dwelling. Use a higher Overlap setting to avoid detecting objects
dwelling nearby.
f Queue Analysis: Used to monitor length of queues, for example, in a point of sale envir-
onment or highway tollbooth. Alarms can be triggered for when a queue grows beyond or
falls below a specified threshold.
g Perimeter: Used to detect when objects enter a protected area through a perimeter
area, or detect when an object is in the perimeter area for too long. Draw regions of
interest to define the perimeter area and the protected area. You must also draw regions
of interest to define the minimum size and the maximum size of objects that can trigger
the perimeter alarm.
