Tripwire
Tripwire is used to define a virtual line within the camera view where an alert can be generated if an object
is detected crossing the line. The Tripwire can also count the number of activations and perform actions
based on the count rule. This could be when a set amount of people have entered / exited an area.
Additionally, a calculated balance of In and Out triggers can be used to trigger alarm when a maximum
total number of people are on one side of the tripwire.
An AnalyticsCapable license enables this feature for all connected analogue cameras.
Up to 16 tripwires can be specified per camera within the view
The Camera Options will configure settings for the camera. Region Options affect only the region
(detection area) currently being configured.
To size and position the Tripwire, use the mouse to click, drag and release the selection points at either
end of the tripwire. Note the Direction arrow, a tripwire can raise an alarm depending on which direction
an object travels across it.
The shaded area denotes the tolerance zone. For an object to register as having crossed the tripwire, it
must be deemed to have entered and exited this tolerance zone. To change the size of the zone, use the
mouse to click, drag and release the centre selection point.
