This function can be used for detecting whether there are people, vehicles and objects
entering into and remaining in the pre-defined region longer than a set duration. You
can set the duration for the alarm response actions, such as full screen monitoring,
audible warning. Intrusion Detection (area violation, with loitering time) allows the
definition of a single area (an area is defined by four points, so it is generally a
‘quadrilateral’. It can be square, rectangular, or a trapezoid that can taper to the shape
of a triangle). There are control settings for sensitivity, percentage of area, and the
amount of time the percentage/sensitivity indicates a change before a VCA event
occurs. This would allow alerts due to persons loitering, or objects left behind, while
ignoring persons and objects passing through an area. This is
in
trusion detection; the
scene is analyzed for movement INTO the area which results in a lasting change.
Movement OUT of the area is not flagged, so while this capability may flag objects
left behind, it will not respond to missing objects.
Steps:
1.
Check the
Enable Intrusion Detection
checkbox.
2.
Click
Draw Area
, and then draw a rectangle on the image as a defense region.
Note:
when you draw the rectangle, all lines should connect end to end to each
other. Four individual points must be defined. Click ‘Stop Drawing’ when
complete. Click ‘Draw Area’ again to drag any of the corners and redefine the
area. Or ‘Clear’ the area and draw it again.
