Queue Line

Queue Line analytics in 3VR VMS sends alerts and events about objects or people in standing in a queue and their average waiting time for checkout. The system sends alerts when the number of people exceeds the threshold limit for a single queue.

Viewing Queue Events

Monitoring Recent Queue Events in the Monitor Panel

The OpCenter Monitor panel allows you to view events as they happen. You can specify which cameras to view, and what types of events are displayed.

Use the following steps to view recent events generated by the Queue Line plug-in:

1. In 3VR OpCenter, click the Monitor tab to go to the Monitor panel.

2. Click camera numbers to select the cameras associated with the Queue Line plug-in.

3. Click the arrow below the camera selector to open the event type drop-down menu.

4. Select [ ]Queue to display events of that type.

5. Click OK. The Monitor panel will update to display only Queue events from the selected cameras.

   

6. To view an event, click the event card. The event card will turn blue, indicating it is currently selected.

Viewing Queue Events

When a Queue event card is selected, the video clip
associated with the event will play back in the video
player.

Details about the event may be viewed in the event
editor, located below the video player.

In addition to the tabs available for all event types,
such as Notes and Images, Queue events include the following information in the Details tab:

• Shortest: The shortest queue observed over the duration of the Queue event

• Peak: The longest queue observed over the duration of the Queue event

• Average: The average queue length over the duration of the Queue event

About Queue Event Cards

A Queue event will be generated in OpCenter at the interval specified during plug-in configuration. By default, a queue event is generated every 2 minutes.

Queue event cards contain pictures, video, and information about the queue. They appear in the Monitor panel for recent events and in the Search panel for search results.

Each Queue event card contains the following information in storyboard view:

1. Thumbnail image

2. Camera number and name

3. Time of event

4. Event type

5. Event length

6. Queue statistics
   with additional information displayed on mouse over:

7. Date of event

Searching for Queue Events

Setting up a Search

Use the Search panel to find Queue events generated days, weeks, or months ago.

1. To go to the Search panel, click the Search tab.

   

2. Define the dates, days of the week, and time ranges to search for events.

3. Under Cameras, select one or more cameras bound to the Queue Line plug-in.

4. Under Events, select [ ]Queue to search for events generated by the Queue Line plug-in.

   The following options are available when searching for Queue events:

   • Click ( )All Queue to search for all Queue events generated during the specified time range.

   

   • To restrict the search further, click ( )Specify. The following search parameters will be available:

     • Peak Queue: Check the box next to [ ]Peak Queue and adjust the Minimum and Maximum slider bars return Queue events with Peak Queue values falling into the specified range.

       

     • Average Queue: Check the box next to [ ]Average Queue and adjust the Minimum and Maximum slider bars return Queue events with Average Queue values falling into the specified range.

       

     • Shortest Queue: Check the box next to [ ]Shortest Queue and adjust the Minimum and Maximum slider bars return Queue events with Shortest Queue values falling into the specified range.

Sorting Search Events

There are two ways to sort the results of a search: by Time and by Similarity. Although the default sort order for standard Motion events is by time, when searching for Queue events with the options under ( )Specify it is recommended to sort by similarity. Sort order is specified when setting up the criteria for a search. To change the sorting of Queue events:

1. Under Events, select [ ]Queue to search for events generated by the Queue Line plug-in.

2. Click ( )Specify.

3. Change the Sort Results By radio button to ( )Similarity.
   

   

When sorting search results by similarity, the following criteria is used to define what “most similar” means for sorting purposes:

• [ ]Peak Queue: Sorts events by queue length. Returns longest queue first.

• [ ]Average Queue: Sorts events by average queue length. Returns longest average first.

• [ ]Shortest Queue: Sorts events by queue length. Returns shortest queue first.

Creating Alerts for Queue Events

In the Alerts panel, you can instruct the 3VR appliance to perform a specified action when video is recorded that matches certain criteria.

Use the following steps to set up an alert that will perform an action, such as sending an email, in response to an event generated by the Queue Line plug-in.

1. To go to the Alerts panel, click the Alerts tab.

2. To create a new alert, click New.
   In the alert editing screen, define the criteria for the alert:

3. Type a name for the new alert.

4. Select a color for the alert. The color will be displayed on event cards that trigger the alert.

5. Specify the day of the week and hours that the alert should be active.

6. Under Cameras, select a camera bound to the Queue Line plug-in.

7. Check the boxes next to one or more alert Actions to carry out when the alert is triggered.

8. If desired, type an alert response procedure. This text will be included with the alert and posted on events that trigger the alert.

9. Under Events, select [ ]Queue.

10. The following options are available when alerting for Queue events:

    1. Click ( )All Queue to generate an alert for all Queue events occurring during the specified time range.

       

    2. To generate an alerts for Queue events with a certain peak, average, or shortest queue
       length, click ( )Specify. The options under ( )Specify are identical to the event selector in
       the Search panel. Please refer to the previous section for more information.

When you are finished defining the criteria for the alert, click the Save button.

The alert will be added to the list of alerts displayed in the main view of the Alerts panel. Click the check box next to the alert to enable it.
