Common questions about library people counting
What is a library people counter?
A library people counter, sometimes called a library visitor counter, door counter or gate counter, tracks how many patrons enter and exit a library. Libraries use this data to plan staffing, manage space, measure program attendance, and support funding and reporting needs.
How long does installation take?
Our PEARL installs in under 15 minutes with peel-and-stick tape or screws, with no wiring and no IT department. Connect it to Wi-Fi through the free app and patron counts appear in your dashboard within 2 hours. Our 3D SCOPE II LC requires ceiling mounting and a single ethernet cable for both power and network. Once physically installed, you book a remote calibration session with the SMS Storetraffic team, who handle the configuration for you.
What is the best people counter for a public library?
For a small public library with a standard doorway and moderate traffic, PEARL is usually the simplest option. It's also the most affordable counter in the lineup, with no wiring or IT support needed to get it running. It pairs well with most standard entrances and gives you reliable patron counts day after day.
How much does a library people counter cost?
A PEARL people counter costs USD 499.95. For busier or wider entrances, the 3D SCOPE II LC costs USD 1,149.95. The Standard plan, designed for libraries, costs USD 33.95 per device per month (USD 27.95 prepaid yearly) and includes the T.M.A.S. web platform, full traffic history and scheduled reports. The free Lite plan works with the mobile app only. See our pricing page.
Why do libraries need a visitor counter?
Most libraries install a visitor counter to prove their value to funding agencies with real usage numbers. Once it's in place, the same data helps schedule staff around busy and quiet hours, spot which spaces or programs draw the most use, and back up budget decisions with facts instead of guesswork.
What visitor data do libraries report to IMLS?
Public libraries report their annual number of in-person visits in the IMLS Public Libraries Survey, usually through their state library agency. An automated people counter gives you that total for any period. Our guide explains what counts as a visit and how to prepare your numbers.
