Introduction to Cross-Camera Tracking

Hardware Requirements

Cross-Camera Tracking is currently supported on select Cisco Meraki smart cameras.

• Gen 3 Dome cameras (e.g., MVx3 series)

Software and Firmware Requirements

To utilize this feature, your network and devices must meet the following criteria:

• Platform: Access to the Cisco Meraki Vision portal (this feature is not available via the Meraki Dashboard, or mobile app).

• Firmware: Cameras must be running firmware version MV 7.2 or above. 

• Camera Configurations:

  • HDR must be disabled on the camera for Cross-camera Tracking to work.

  • If License Plate Recognition (LPR) is enabled, Cross-camera Tracking will not be available. 

  • To learn more about feature compatibility please see more here.

Licensing Requirements

No additional feature license required: Cross-Camera Tracking is included at no extra cost.

Role-based Access Control (RBAC)

Single Camera View

In the Vision Portal, selecting an individual camera opens the Single Camera View. 

1. Open the Single Camera View: Select the specific camera that captured the person of interest to open its video feed.
2. Pause the Video (Important): Cross-Camera Tracking requires historical footage to analyze the image. You must pause the video on the frame showing the person of interest. Note: A search will not trigger on live video or video that is currently playing.
   • 
3. Initiate the Search: Once the video is paused, select the Search button.
   • 
4. Select a Result: Choose the relevant person from the populated results. Selecting a result will automatically navigate you to the Cross-Camera Tracking person of interest search page, where you can see their movement across the network. See below for more details. 

Event Search

1. Navigate to Event Search: Open the Event Search tab from the main menu.
   • 
2. Perform a Standard Search: Enter your search parameters (such as date and time, and up to four cameras, and attributes if you have that information). 
   • 
   •  
3. Wait for Objects to Load: Once the initial video results are displayed, the system will automatically begin loading and highlighting all the objects detected in the frame. 
   • 
4. Select Your Subject: Click on the specific person of interest from the loaded results. This will navigate you to the Cross-Camera Tracking page to view their movement across your deployment.

Cross-camera Tracking Results

Once you select a person of interest from either the Single Camera View or Event Search, you will be taken to the dedicated Person of Interest (POI) search page.

On this page:

• Your selection drives the search: The person you clicked on in either the single camera view or event search becomes your visual search criteria.
• Results are compiled: The system displays a timeline of all detected clips of that person across your network grouped by Similarity. 
  • Similarity refers to how closely the AI believes a person in another video clip matches the visual characteristics of your original Person of Interest (POI).
  • The results are displayed based on similarity by default, but the results can also be displayed by Newest to Oldest, and Oldest to Newest. 
    • 
• Refine your results: If you do not see enough clips, adjust the similarity slider to broaden the search and generate more potential matches.
  • By default the similarity is set to a 77% match, but if you do not get enough results you can adjust the similarity to a rough match to get more results, or an exact match to get results closer to your visual search criteria. 
  • 
  • The cameras with results section will display all the cameras in the network and show which cameras have results and which do not. 
    • You are able to filter the results out based off the camera, and show and hide camera results.
