Overview
Use the Line Crossing report type to count events for any vehicle or person that crosses a specified line in one or both directions. To customize the report, configure the following settings:
Object Types: Uses Coram's powerful AI model to count specific objects:
Vehicle - motion from most common vehicle types including cars, trucks, vans, forklifts, semis, and other site vehicles.
Person - motion from people.
Crossing Line: For each camera that you add, you must draw a line to monitor for crossing events. You can monitor crossings in both directions (
, selected by default) or one (
, 
) direction.
Creating a Line Crossing Report
To create a Line Crossing report and add it to a dashboard:
Access the Coram web app and sign in to your account.
From the main navigation menu, select Insights.
In the top left corner of the page, use the dropdown arrow ( ▼ ) to select the dashboard where you want to create the new report.
In the top right corner of the page, click + Create Report.
The New Report page appears.
Add a name, optional description, and time period for the report.
For Report Type, select Line Crossing Report, then configure the report settings.
Select + Add Cameras, then select the corresponding check box for each camera you want to include and click Save.
For each camera that you selected, define the crossing line and crossing direction.
From the Report Visualisation menu, choose one or more of the following options:
Event Counter: Shows a cumulative counter for the total number of events across all selected cameras.
Graphs: Shows a non-cumulative line graph over time for all events across all selected cameras.
Video Clips: Shows a clickable video thumbnail for each event across all selected cameras.
To save the report and add it to the dashboard, click Create Report.
Best Practices for Line Crossing Reports
To ensure accurate counting and reliable detection, follow line placement guidelines:
Clear Visibility
Position lines to capture a clear view of the area before, during, and after the crossing line without obstructions from trees, columns, walls, etc. This allows the system to accurately detect and track objects as they approach and pass through the line.
Good Example:
Bad Example:
Adequate Coverage
The camera's field of view should extend at least 6-10 feet on either side of the line to provide sufficient tracking distance.
Good example:
Bad example:
Distance from Entrances
Avoid placing lines too close to doorways or entrances without adequate perspective. Position the line at least 3 feet away from entry points to allow proper detection before crossing occurs.
Good example:
Bad example:
Direction of Travel
Draw the crossing line perpendicular to the expected path of movement for the most accurate counts. The position and angle of the arrow is less important, and only signifies the general direction of the crossing.
