The PEARL Wireless People Counter

—- Empty —-

Everything you need. PEARL comes with pre-installed AA batteries, mounting brackets with peel-and-stick 3M™ tape already in place, and a special tool to press the hidden setup button. In other words: PEARL is ready to be installed in minutes—just stick at the entrance, pull the battery pull tabs, download the app, and follow the simple steps.

Yes. The PEARL People Counter works as a pair of two sensors, one main and one secondary unit. These two sensors come standard with every PEARL system at USD 499.95.

Install a sensor on each side of the doorway; when someone passes through the beam, PEARL adds that person to your foot traffic data. PEARL’s sensors are bidirectional, counting both ins and outs separately.

Yes, it is. No wires are needed. PEARL is WiFi-enabled and works with standard AA batteries.

• Communication frequency with the server: the LITE Plan connects to the server every hour. 30–min and 15–min intervals, or even real-time* connection, are available with other Plans.
• Distance between sensors: PEARL automatically adjusts its signal detection capability when the primary and secondary units are farther apart—this draws more energy from the battery.
• Sunlight exposition: PEARL automatically adjusts its signal detection capability when exposed to sunlight—this draws more energy from the battery.
• WiFi signal strength: if the WiFi signal is low, PEARL may require more energy from the battery to establish a connection.
• Regular blocking of the beam signal: PEARL will send alerts every time its signal is blocked by someone or something for more than 60 seconds. If this happens often, it could affect battery life.
• Regular business or operating hours: PEARL shuts down automatically to save the battery energy according to hours you entered in the software.
• Use of Energizer™ batteries: high-quality batteries make a real difference. Some inexpensive batteries have low capacity and end up costing more in the long run.

Yes. Although we do not recommend it for occupancy monitoring, as PEARL can only count one person at a time. The 3DScope II LC is the better product for occupancy monitoring.

In Real-Time Mode, PEARL will stay connected to your WiFi, and it will send counts immediately, as they happen. We recommend using Battery to Power Outlet adapters, sold on Amazon, as batteries will only last a few days in Real-Time mode.

PEARL will not register multiple counts if someone stands still between the sensors. If someone or something blocks the beams for more than 60 seconds, PEARL will send you a heads-up message by email.

PEARL has a built-in memory and can store up to 24 days of data. It will continue to count, even if the WiFi network is down.

If the battery runs out, the internal memory will keep track of all the people counts that weren’t sent to the server. PEARL will transfer the data to the server as soon as good batteries are installed.

To count accurately, the PEARL People Counter requires an unobstructed view between the sensors. Varying tint, thickness, or reflective properties of glass can affect PEARL’s beam signal. Our 3D SCOPE II LC People Counter would be a better solution in this context.

There’s no need: PEARL is so easy to install, anyone can do it. The simple installation steps are included in the app’s installation guide.

There’s also a video to help you out.

We recommend installing PEARL at the height of 54 inches. This height should be measured from the bottom of the sensor to the ground. Make sure the sensors are installed higher than any door handle.

No. Once placed in its brackets, PEARL is solidly locked in. The double-stick tape used to affix the brackets is very strong. There’s also a screw at the bottom to make the sensors even harder to remove. The brackets themselves can be screwed in instead of the stick-on-install option, using three screws placed through the beveled screw holes.

Storetraffic engineers in Canada developed PEARL. It’s also manufactured in Canada.
