Les enjeux

The questions that each event configuration raises

01

How do you accurately track entries when crowds arrive in dense waves?

The counter handles high traffic. For optimal results during high traffic, we recommend installing it at a passage point where users pass one by one (e.g., entrance, barrier, turnstile).

02

How do you account for re-entries and exits to calculate true attendance at any moment?

Bi-directional detection distinguishes between entries and exits to estimate net occupancy, not just the total number of passages.

03

Can you count large flows accurately when people move in groups or waves?

The sensor range (1 to 6 m, optionally up to 12 m) adapts to the width of the counting point.

04

How do you control access to a restricted area without dedicated staff?

The sensor operates completely autonomously for up to 2 years, regularly transmitting data to the platform.

How it works

Step 1

The sensor detects every pass

Thermal technology: the sensor reads the body heat of each user. No cameras, no images, no personal data.

Detection in both directions

Full GDPR compliance

Step 2

The device records and classifies

Each passage is timestamped and classified by mode and direction.
Data is aggregated into 15-minute intervals directly within the device.

Secure local storage

Step 3

Data goes to the cloud

Depending on the chosen frequency (from 5 minutes to 24 hours), the device sends its data via the available network.
If there's no network, local Wi-Fi data collection is still possible.

During the event

Our Recommendations for Event Counting

For the densest flows, a simple and proven system prevents group effects and ensures data reliability: channeling visitors into individual lanes before they pass the sensor.

1

Visitor Arrival Zone

The public arrives in compact groups, without any specific organization.

2

Staff Screening

Volunteers or staff perform an initial screening, preventing crowds from forming in front of the sensors.

3

Flow lanes

Barriers and tarpaulins create defined lanes with Verdilo sensors. Each visitor passes individually, without stopping or friction.
