Configuring Scene Analytics Detection Tools

[Music] to activate a VCA tool go to the detection tools tab create an object tracker the following video content analysis tools enable scene analysis in axon one line Crossing loitering in the area stop in the area abandoned object Motion in the area appearance in the area Disappearance in the area multiple [Music] objects after it's created the object tracker object is enabled by default you can bolk configure all scene analytics detection Tools in this object the viewing tile displays tracked objects parameters width and height relative to the frame size and color if you disable the object

track tracker object all scene analytics tools will be disabled as well as object tracking Auto zooming tag and Track Pro and moment Quest functions some parameters can be bulk configured for all scene analytics detection tools to configure them do as follows create an object tracker by default video streams metadata are recorded into the the database you can set the minimum and maximum object size for detection by specifying numerical values or reference areas on screen objects of all sizes beyond the set values will not trigger detection to set reference areas in the camera window click the

mint button and set the minimal dimension of the object of Interest then click the max button and set the maximum [Music] dimension [Music] to use the numerical setting you need to specify the percentage to frame dimensions in the following Fields maximum height and maximum width and minimum height and minimum [Music] width in the tracker timeout field enter the time interval in seconds during which the object's properties will be stored in the tracker's database in the motion detection tool sensitivity field enter the motion sensitivity value for scene analytics detection tools on a scale of 1 to

80 by default scene analytics is performed within the whole frame if you need to prevent an area from the analysis and metadata generation click the mask button and specify the required area to cancel a mask click the x button let's adjust the object tracker to prospective Distortion in object tracker settings you can use the simplified perspective calibration function to match the size of objects on the foreground and background the perspective calibration is used to make the object tracker perform better in the object tracker settings specify the height of the reference object in decimeters select yes

for the object calibration op [Music] then click the perspective button and specify no less than four segments for calibration the segments will be longer the closer they are to the foreground the object tracker is now adjusted to prospective Distortion let's try the Line crossing detection tool part of the seam analytics toolkit after you create a line Crossing detection tool you can see a virtual trip wire line in the faux V set the end points of the line the end points are connected by a two-color dotted line the direction of the object's motion across the line

is indicated by dotted Arrows by default the motion across the line is tracked in both directions to suspend motion detection in One Direction click the plus button button corresponding to that direction an unmonitored direction of object motion is indicated by a dimmed Arrow select the type of the target object that should trigger the detector if necessary select a color or a color range for the [Music] object click the apply button [Music] the Line crossing detection tool is now [Music] configured
