Description
Intrusion
Draw a detection area.
Abandoned object
Missing object
Fast moving
Parking detection
●During the detection of abandoned object, the alarm is also
triggered if pedestrian or vehicle stays for a long time. If the
abandoned object is smaller than pedestrian and vehicle, set the
target size to filter pedestrian and vehicle or properly extend the
duration to avoid false alarm triggered by transient staying of
pedestrian.
Crowd gathering
Loitering detection
●During the detection of crowd gathering, false alarm might be
triggered by low installation height, large percentage of single
person in an image or obvious target occlusion, continuous
shaking of the camera, shaking of leaves and tree shade,
frequent opening or closing of retractable door, or dense traffic
or people flow.
Step 6
(Optional) Click other icons at the right side of the image to filter targets in the image.
●Click
to draw the minimum size of the target, and click
to draw the
maximum size of the target. Only when the target size is between the maximum size
and the minimum size, can the alarm be triggered.
●Click
, and then press and hold the left mouse button to draw a rectangle, the pixel
size is displayed.
●Click
to delete the detection line.
Step 7
Set rule parameters for IVS.
Table 8-9 Description of IVS parameters
Parameter
Description
Set the direction of rule detection.
Direction
●When setting tripwire, select A->B , B->A, or A<->B.
●When setting intrusion, select Enter , Exit, or Both.
When setting intrusion action, select Appears , Cross or Inside.
Action
Inside and appears/cross cannot work at the same time.
Target Filter
When Target Filter is enabled, the system only detects the selected
effective targets, and only the selected targets can trigger the alarm
rules.
●Target Filter are only available under tripwire, intrusion, and fast
moving rules.
Effective Target
●Human and Motor Vehicle are selected by default.
●Currently, the algorithm primarily supports the detection of cats
and dogs in the animal category. Although it can also attempt to
detect other four-legged animals, the accuracy of such detections
cannot be guaranteed.
