With Solink's Line Cross feature, you can create a line within your camera view and automatically generate an event that compiles the total number of people who crossed the line within a short period of time. Once you have created the line, Line Cross events are generated on the Events page every 5 minutes.
You can configure various types of line directions to track:
In and Out traffic (entrances and exits)
Left to Right traffic (passerby traffic outside the storefront)
Up and Down traffic (floor to floor transitions, such as escalators and stairways)
Note: Line Cross Events are available with a subscription to Solink's AI Package.
Line Cross events provide useful data to help you:
Detect illegal entries or exits.
Rank stores by conversion rate.
See fluctuations in store occupancy over time.
Record passerby traffic.
Better understand customer flow to adjust staffing levels.
How Line Cross Events Work
Line Cross Events allows you to draw a line in the camera view and generate events containing important line cross data.
A Line Cross event is generated every 5 minutes and accessible via the Events page.
Line Cross events contain the following information:
Line label: The name of the line (configured when creating the line)
The number of people who crossed the line in either direction (in/out, left/right, up/down).
The data available in Line Cross events allow you to create helpful widgets on the Dashboard page. See Line Cross Widgets further in this article for more information.
Enable Line Cross Events
You must enable People Analytics on one of your cameras in order to enable Line Cross Events.
See Enable People Analytics for information on how to enable Line Cross Events.
Note: Additional permission is required to manage people tracking on your cameras. Please reach out to our Support team if you require permission.
Note: People tracking can only be enabled on one camera. However, you can disable people tracking on one camera and enable it on another whenever required.

To configure a line for Line Cross events:
Navigate to the camera you want to configure a line for (select the Video page > select the camera to open the video player).
Select the AI button > Line Cross in the top-right corner of the video player:
For the next step, there are two different methods to create a line for Line Cross events.
Method 1: Review Accuracy of Line First
You may want to review the accuracy of the line to determine if it is tracking data correctly and you are happy with the line location. See Method 2 if you are not interested in this step.
Within the Search tab, first create a line (refer to Line Cross Search configuration instructions here if needed).
Evaluate the accuracy of your line - if the AI is correctly tracking people as they cross the line and you are happy with the line location, select Configure near the bottom of the page:
Next, see Edit and Save Line below.
Method 2: Create Line Immediately
To create the line immediately (and skip testing the accuracy of the line):
Select the Events tab:
Click in the camera view to create your line:
Edit and Save Line
To finish editing and save your line, follow these steps:
Select the "More Options" button (three dots icon) to choose the Line Type:
Choose from on of the following Line Types:
Entrance and Exit: Select this Line Type and draw the line near a door to track the number of people who enter and/or exit the location. This is the only Line Type that, when selected, automatically generates Location Occupancy events.
Passerby Traffic: Select this Line Type and draw the line outside of the entrance of the store (for example, outside of a strip mall) to track the number of people who either pass by the location outside or enter.
Floor Level Transition: Select this Line Type and draw near an elevator/escalator to track the number of people who transition from one floor to another.
Select the "pencil" icon to edit the line name. This will help you locate the line later on the Events page as the event name will be the same as the line name:
Location Occupancy Events
Location Occupancy events are generated every 15 minutes and provide you with up-to-date, accurate store occupancy numbers:
Location Occupancy events are only generated if you select the Entrance and Exit Line Type.
These events display the total number of people who crossed to both the In and Out sides of the line in the given 15 minute interval, providing you with context for the Current Occupancy.
