Learn how to create and customize Line Crossing reports.

Updated over a month ago

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.

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.
