Solink's Line Cross Search feature allows you to quickly track foot traffic in your store over a given period of time and combine that information with POS data to gather revenue statistics.
Note: Line Cross Search is available with a subscription to Solink's AI Package.
Line Cross Search allows you to gain insights into the following:
The total number of people who walked across either side of the drawn line within your camera footage during a given period of time.
The daily average of visitors.
The approximate occupancy of your location.
Revenue per customer.
Note: This feature requires your Solink recording device (QNAP) to have an AI chip installed. Please reach out to our Support team if you are unsure if your recording device has an AI chip installed.
How Line Cross Search Works
Line Cross Search uses people tracking AI to detect movement as individuals walk within your camera view.
By drawing a virtual line, you can quickly review the total number of people and daily average of people on either side (if you select more than a day for the Start Time and End Time):
Enable Line Cross Search
You can access Line Cross Search in the Solink video player. However, you must first enable People Analytics on one of your cameras in order to use the feature for that camera.

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.

Tip: Refer to Camera Placement Guide for People Tracking for more information on how the camera position and angle can impact Line Cross accuracy.
Configure Line (Switch Directions)
To switch the direction of the line, either:
Select the Swap Direction button:
Select the "triangle" icon on either side of the line:
Tip: Configure the line so the blue triangle is facing in to your store and the orange triangle is facing out. This ensures you are tracking Approximate Occupancy accurately.
Navigate to each Line Cross in Video Player
Once you have created a line, you can use the Next Line Cross and Previous Line Cross buttons to navigate to each instance a person crossing the line.
The orange and blue circles on the timeline correlate to someone crossing the line to either the blue or orange side of the line:
Summary Statistics
Line Cross Search allows you to calculate revenue statistics based on the number of people and transactions over the selected timeframe.
Select a revenue source/sources to calculate the following metrics described below:
Note: Suggested revenue sources include your POS systems - you should either see the name of the POS system(s) in the Revenue Sources dropdown list or the name "Passthrough" which can also represent your POS system(s).
Approximate Occupancy: Calculates the total number of people in your location over a given period of time. Approximate Occupancy is calculated by the number of people who crossed to the blue side of the line, subtracted by the total number of people who crossed to the orange side between your Start Time and End Time. This gives you the Approximate Occupancy at your location as of your End Time.
Conversion Rate: The total number of transactions, divided by the Total People (Blue), represented by a percentage.
Revenue Per Customer: The total $ amount of transactions, divided by the total number of transactions.
