Section 3: Analytics & Alarm Rules
3.1.3 Drawing a One-Way Trip Wire
A single directional trip wire (Fig. 21) has an arrow facing one way. This is
used for detection of objects moving in one direction, for instance, people
coming in through the door and not out.
The arrow can be pointed at any direction. To draw a trip wire, left click
on a starting point, and without releasing drag the mouse pointer to the
intended length, and move clockwise or counterclockwise until the desired
direction of the arrow is achieved, and then release.
3.1.4 Drawing a Two-Way Trip Wire
A multidirectional trip wire looks like a plain line with no arrows. It is drawn
using the same methodology described in drawing a one-way trip wire
(Section 3.1.3).
3.1.5 Changing the Shape of an Analytic Rule
To apply a new shape to an analytic region, select the associated rule,
select the new shape in the Rule Shape pane, and draw as described in
the above subsections. Any change or update to a rule is applied only after
clicking the Update Rule button and the Apply Changes to Camera button.
