Capacity Monitoring


Via Guide Capacity Monitoring powered by Qmetrix are solutions to measure filling levels of areas and zones. With our sophisticated technology it’s not necessary to cover a full area with sensors. Our sensors detect the access to and exit from these areas, like terminals, corridors or lounges. Using statistical methods, it is then possible to calculate the filling level and an average dwell time — based on a ‘First In, First Out’ principle.

Our Qmetrix Ranging Sensor is a 3D laser sensor, which is mounted to the ceiling and provides a counting accuracy of more than 99%. This sensor is not disturbed by lights, shadows or reflections. As well as the sensor data, it is possible to integrate third-party data — like from other sensors, metal detectors or eGates.

All the gathered data is available in real-time and historically, for in-depth analysis.

Avoid overcrowded areas before they happen with real-time alerts! Sell over capacities in lounges to other airlines! Improve your staff planning based on passenger forecasts!

Our goal in gathering capacity KPI is to have a simple and cost-effective solution for customers. Compared to other products on the market we are not tracking passengers through the area, which requires a high number of sensors in order to cover the whole queue. Our method is based on the ‘First In, First Out’ principle. This allows us to position counting points at relevant positions, such as entries and exits, which reduces the number of sensors enormously. Depending on the requirements, we rely in our own sensor or in the usage of existing third-party data.


The following data is determined: access rate, service rate and filling level.

All data is uploaded and calculated on the Qmetrix webservers, where the data is stored and aggregated.

All data is available in real-time. This allows for displaying real-time information about waiting times to passengers or get notified with alerts when waiting times are exceeding.

All the data can be analysed with the web-based Qmetrix Analytics platform with many standard reports.


Unlike stereo video systems, this 3D laser sensor is completely independent of light and is therefore not affected by direct sunlight, shadows or reflections. The sensor is optically unobtrusive, requires only a PoE connection and is mounted to the ceiling. Its counting accuracy is higher than 98%.

Our counting portal offers a combination of high quality counting and flexibility. The sensor is located overhead on the portal behind the panel with the queue identification. This eliminates high installation costs. As an option, a screen can also display dynamic content, such as the current waiting time.

In addition to our sensors, data from third-party systems can be integrated to our measurement. This can either save sensors or improve data quality. The following data can be integrated by us: sensors of other manufacturers, boarding pass readers or eGates. The prerequisite for this is that the data is available in real-time.
