Define what causes an alarm, such as motion detected, people loitering, door access, etc.
In the Rules page, click Add Devices. Rules can be set up only if an analytic is running against a camera. Hover the mouse over the camera name. If the camera is not associated with an Add-On (analytic), a message indicates that you cannot add it to an event.
Select one or more cameras, IO devices, and access control devices.
Click OK. The devices you selected are listed. (Optional - To remove the camera from the list, hover over the camera name and click Remove.)
Enter an identifiable name for the event in the Name field.
For cameras, perform the following steps:
Select and configure a video analytic that is active on
the camera to trigger the event.
The settings vary with the video analytic:
PTZ Auto-Tracking (For the PTZ Auto-Tracking rule, you will select one of the motion detection analytics running on the camera.)
If applicable, define the area to be analyzed/ignored in the video for motion using the processing mask.
In Drawing Mode, select either Analyze or Ignore and drag the mouse pointer over the image. Areas to be analyzed are in yellow. Areas to be ignored remove the yellow mask.
For masking of small details, reduce the size of the mouse pointer by moving the Size slider.
For IO devices and camera motion detection, perform the following steps:
For input, select Input Ports, type the input module and port, and select whether the event triggers on activation or deactivation of the input.
Select whether motion detection triggers an event.
Select whether camera tampering triggers an event.
For access devices, select access inputs that trigger the event in Symphony.
Click Save.
If you have more than one event for a camera, select whether Events must occur in sequence or within a time period of x seconds. (Events are listed in the sequence you created them. Hover over the event name and click the arrow icon to move or delete the event as necessary.)
Continue with Action.
The event settings for Crowd Detection are visible when you select Crowd Detection as the video engine.
Select whether the event responds to capacity or occupancy.
Set the amount of time over which Crowd Detection averages values to reduce the number of false alarms.
Use the slider bar to define the values that trigger the event. Values that fall outside of the threshold trigger the event.
Select whether one or all of the following will be tracked: People, Vehicles, Unknown (objects, e.g. animals)
Select the type of movement to alarm on:
Moving for at least _ seconds
Loitering for at least _ seconds
Any part of track denotes the object can be anywhere in the Analyze zone to trigger an alarm.
Beginning of track denotes that the object started moving in the Analyze zone.
End of track denotes that the object has stopped in the Analyze zone.
Any part of object denotes that any part of the object can be anywhere in the Analyze alarm zone to trigger an alarm
Any fence - an object must pass through any of the fences to be detected.
All fences - an object must pass through ALL of the fences to be detected.
Left-click on the image and draw a line that will cause people to be detected as they pass the delineated area. The line appears with arrows indicating the direction of moving objects to be detected.
Click on one of the arrows to remove it. The remaining arrow indicates the direction of movement in or out of the delineated area.
To switch the direction, click on the existing arrow. It disappears and a new arrow appears in the reverse direction.
Define the area to be analyzed/ignored in the scene where an object (either left behind or removed) should be detected. Objects that are left or removed outside the red alarm zone will not cause alarms.
In Drawing Mode, select either Analyze or Ignore and drag the mouse pointer over the image. Areas to be analyzed are in yellow. Areas to be ignored remove the yellow mask.
For masking of small details, reduce the size of the mouse pointer by moving the Size slider.
Alarm based on percentage of object inside alarm mask - Indicate how much of the object should be in an alarm area for it to be detected. For example 75% of a knapsack in an area.
Define the limits of the object to be detected - green box for smallest size and red box for largest size.
Alarm only, if: Defines how many alarms must occur in predetermined time. Example case: Retailers who want to alarm only if a certain number of items are removed from a shelf in a pre-determined time. For example, 2 LCD monitors must be removed before the event is triggered.
OR, at least: Defines the size of alarm in cases where multiple objects are removed but they are so close together it creates one alarm. Set size of box based on changes in scene (pixels)
Selecting both options is ideal where many small background changes or one large background change (caused by a removed item) can trigger the event.
Alarms Occur (seconds): Based on alarms detected
Pixels Change (seconds): Based on pixels changed.
Set size of box to Y pixels, where we alarm if at least Y pixels change
Any part of track denotes the person or car can be anywhere in the Analyze zone to trigger an alarm.
Beginning of track denotes that the person or car started moving in the Analyze zone.
End of track denotes that the person or car has stopped in the Analyze zone.
Any part of object denotes that any part of the person or car can be anywhere in the Analyze alarm zone to trigger an alarm.
Important: For the PTZ Auto-Tracking rule, you will select one of the motion detection video analytics running on the camera.
Any part of track denotes the person or car can be anywhere in the Analyze zone to trigger an alarm.
Beginning of track denotes that the person or car started moving in the Analyze zone.
End of track denotes that the person or car has stopped in the Analyze zone.
Any part of object denotes that any part of the person or car can be anywhere in the Analyze alarm zone to trigger an alarm.
Match Threshold defines how closely the detected face must match a face on the blocked list to trigger an alarm or a face on the allowed list to not trigger an alarm. This setting does not apply when you select Alarm on all faces.
Alarm on all faces triggers an alarm when a face is detected.
Alarm only on faces in the blocked list triggers an alarm when a face from the blocked list is detected.
Alarm only on faces not in the allowed list triggers an alarm when a face that is not on the allowed list is detected.
