Before you can monitor KiwiVision™ in Security Desk, you must configure intrusion detector areas settings for your camera.

What you should know

Intrusion mode is the default intrusion analytic and has three areas:

A green source (entry point) area, an orange transport area, and a red sink (exit point) area.

Intrusion mode is used when you want to detect and analyze movement from one area to another. The movement begins in the green source (entry point) area, travels through the yellow transport area, and ends in the red sink (exit point) area.

Zone mode has only one area: the red sink (exit point) area.

Zone mode is used when you want to detect and analyze movement in the sink (exit point) area only.

You can add multiple area layers to monitor for intrusion. An area consists of a sink (exit point) region, with zero-to-many source (entry point) regions.

When an intrusion is detected that layer turns blue. When you enable the Advanced mode KiwiVision annotated overlays are displayed.

Procedure

  1. In Config Tool select your intrusion detector.
  2. In the Areas tab, configure the Areas objects.

  3. Click and drag the Area objects to the area of the video that you want to monitor for intrusion.
    1. Click and drag the white dots to adjust the source (entry point) or sink (exit point) object size or orientation as required.
      Click a line to create a point, drag to move a point, or double click to delete a point.
    2. (Optional) Use the Areas toolbar to perform the following:
      • add areas ()
      • remove areas ()
      • add source () or sink regions ()
      • or remove regions ()
      NOTE: Adding an Area automatically adds the area with one source entry point region (green) and one sink exit point region (red).
  4. In the Area section, configure the area settings.
    Configure the Tracking settings as required:
    Min. speed
    Specifies the minimum speed of an object or person in the image region that can trigger an alert. You can specify values in the range 0.01 - 3 m/s (0.033 - 9.9 ft/s).
    NOTE: The velocity estimation is based on the configured perspective and depends on the accuracy of the configuration.
    Max. speed
    Specifies the maximum speed of an object or person in the image region that can trigger an alert. When this maximum speed is exceeded no alert is triggered. You can specify values in the range 1 - 100 m/s (3 - 327 ft/s).
    Max. deviation
    Specifies the maximum number of degrees that movement in the image can deviate from the configured path and still be considered active motion and trigger an alert. You can specify values in the range 5 - 180 degrees.
    For more information about configuring paths, see Configuring intrusion detector paths settings in KiwiVision™.
    Min travel
    Specifies the distance that an object or person must travel in the image to be considered active motion and trigger an alert. You can specify values in the range 0.1 - 10 m (0.3 - 33 ft).
    NOTE: The distance is estimated based on the configured perspective, which might result in inaccuracies.
    Configure the Alert settings as required:
    Min. time
    Specifies that after an alert is sent for an area, additional alerts that are specific to that area are suppressed until the specified time period has elapsed. You can specify values in the range 1 - 100 seconds. Using a low value ensures that multiple alerts that are part of a single real-life event are captured. Using a high value might suppress valid alerts that happen quickly after one another.
    Activate after
    Specifies how long an alert must be detected for before it is sent. A high value filters out camera noise, but might result in missed alerts. You can specify values in the range 0.1 - 10 seconds.
    NOTE: If an intruding object in the scene reaches the Min. speed, does not exceed the Max. speed, takes at least the Min. travel and moves within the Max. deviation angle along the defined path for at least the Activate after period of time, then an alarm will be triggered.
    Min. size
    Specifies how much of the object size area has to be active in the sink (exit point) region to trigger an alert. You can specify values in the range 10 - 100 %.
    NOTE: If this parameter is set to a low value, small motion patterns (such as those of animals) are detected as well. If this parameter is set to a high value, it can result in missed detections of objects or individuals.
    Detection clustering
    Suppresses alerts that are triggered by scattered movements in the image, such as motion caused by camera noise.
    NOTE: Using this option can lead to missing valid alerts if the movement is not clearly detected.
  5. Click Apply.

After you finish

You can now configure your intrusion detector Paths tab settings.
