Advanced Object Event Cards
An Advanced Object event will be generated in OpCenter whenever an object is captured on a camera bound to the Advanced Object Tracking plug-in.
Advanced Object event cards contain pictures, video, and information about each tracked object. They appear in the Monitor panel for recent events and in the Search panel search results.
Each Advanced Object event card contains the following information in storyboard view:
Thumbnail image
Camera number and name
Time of event
Event type
Length of the event video clip
Color bar (Displays the object’s three most prominent colors)
Direction icon
Event details (Lists the properties of an event card. The Colors are referred to by their color IDs. To cross-reference an ID with its corresponding color, see the Search panel color selector)
with additional information displayed on mouse-over:
Date of event
Viewing Advanced Object Event Video Clip
To view the video clip and other details of an Advanced Object event, click the event card. The video clip will play back in the video player.
To display an overlay identifying the tracked object, right-click the video player and select Overlays-> Show Object Tracks. Refer Watching Video with Object Overlays section for more details.
Viewing Event Details
When an Advanced Object event card is selected, 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, Advanced Object events include the following information in the Details tab:
Colors: The object’s three most prominent colors
Directions: The direction the object was traveling it
Speed: The speed of the object
Size: The size of the object relative to the rest of the field of view
Aspect: The aspect ratio of the object
Searching for Advance Object Events
Setting up the Search
Use the Search panel to find Advanced Object events recorded days, weeks, or months ago.
To go to the Search panel, click the Search tab.
Define the dates, days of the week, and time ranges to search for events.
Under Cameras, select one or more cameras bound to the Advanced Object Tracking plug-in.
Under Events, check the box next to [√]Advanced Object to search for events generated by the Advanced Object Tracking plug-in.
The following options are available when searching for Advanced Object events:
Select (•) All Advanced Object to search for all objects captured during the specified time range.
To restrict the search further, select (•) Specify. The following options are available to search for specific objects:
[√] Color: Click and drag to highlight one or more shades. The colors selected must be adjacent. Note that the ends of the color selection tool wrap around.
[√] Direction: Search for objects moving in a specific direction.
[√] Zone: Draw a zone to search for objects traveling through the zone.
Click the video player to begin drawing a zone. Each click of the mouse will create a new line segment. To complete the
polygon, click the mouse over your start position.[√] Size: Choose the object size relative to the field of view to search for.
[√] Aspect Ratio: Choose the approximate aspect ratio of the object to search for.
[√] Duration: Restrict your search results to object events falling within a minimum and maximum duration.
When you are finished defining the criteria for the search, click the Search button.
Advanced Object events matching your criteria will be displayed in the Search panel results screen.
Select an event card to view the video clip and details associated with the event.
Sorting Search Results
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 Advanced Object events using the options under (•)Specify it is recommended to sort by similarity. This will place the Advanced Object events that best match your criteria at the top of the Search panel results screen.
Sort order is specified when setting up the criteria for a search. To change the sorting of Advanced Object events:
Under Events, check the box next to [ ]Advanced Object to search for events generated by the Advanced Object Tracking plug-in.
Click (•)Specify.
Change the (•)Sort Results By button to (•)Similarity.
Modify the (•)Specify search options as desired. The following options will produce meaningful results when sorting by similarity:
[√]Color
Sorts matching objects by color. returns closest color match first.[√]Zone
Sorts objects by time spent in the zone. Returns longest visitor first.[√]Direction
Sorts objects by time spent traveling in the selected direction. Returns longest traveler first.
Creating Alerts for Advanced Object 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 Advanced Object Tracking plug-in.
To go to the Alerts panel, click the Alerts tab.
To create a new alert, click New.
In the alert editing screen, define the criteria for the alert:Type a name for the alert.
Select a color for the alert. The color will be displayed on event cards that trigger the alert.
Specify the day of the week and hours that the alert should be active.
Under Cameras, select a camera associated with the Advanced Object Tracking plug-in.
Check the boxes next to one or more alert Actions to carry out when the alert is triggered.
If desired, type an alert response procedure. This text will be included with the alert and posted on events that trigger the alert.
Under Events, check [√]Advanced Object.
The following options are available when alerting for Advanced Object events:Select (•) All Advanced Object to generate an alert for all objects captured during the specified time range.
To create an alert for specific objects, select (•)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.
Advanced Object Event Reports
Running Advanced Object Event Reports
