Users are able to draw lines on any camera feed, name them, and define a “forwards” and “backwards” way to cross the lines. With this, users count the number of people, cars, or animals that cross the line. The lines can also be set to trigger real-time alerts if they are crossed, or if they are crossed a certain number of times. If lines are drawn at every entrance and exit, BASS provides real-time data on the number of people in a business. This capacity monitoring is useful for COVID-19 protocol, fire code limits, and other regulatory compliance requirements.
