Airport Products

The Xovis Passenger Tracking System (Xovis PTS) enables airports to reach new levels of Passenger Flow Management in terms of measurement as well as analysis. Besides normal Passenger Counting and tracking, Xovis PTS also precisely measures process and waiting times in queuing areas, queue fill levels and in and outflow as well as counts of open lines and desks. The behavior of passengers can be analyzed, and the Passenger Flow can be managed by adjusting signalization and controlling escalators for example.

Airport Products Overview

Our PC Sensors

The Xovis PC2/3 3D stereo vision person tracking sensor is the most advanced technology for person, vehicle and bag tracking available today worldwide. On-sensor video-analytics (no video needs to be streamed from the sensor), multi-sensor capability, the ability to manage mounting heights of up to 20 meters as well as an area coverage of 100 m2 per sensor are unique features that optimally address the challenges of airports when it comes to Passenger Tracking and Passenger Flow Monitoring.

Xovis Suite

The Xovis XS Suite is a Windows server-client software, which receives the data streams (no video, just moving coordinates for every single passenger) from all sensors, calculates based on these streams all KPIs, including waiting times, process times, people counting etc. Thresholds and Service Levels can be set and monitored, alarming rules help to get notified.

The PC Sensors

Have a look at our Sensors

The Xovis 3D Stereo Vision Person Tracking Sensor Series comprises two sensor types: the People Counting Sensor 2 (PC2) and the People Counting Sensor 3 (PC3). For every sensor, the mounting height lies between 2.2 m up to 20 m. To optimize the area coverage the sensors are availabe with various different lens options; the PC 2 Series comes with three options while the PC 3 Series are featured with even five lens choices. Starting at an installation height around 6.5 m, a constant coverage of 100 square meters is granted.The Xovis PC 3D stereo vision sensor integrates a powerful and specialized processing engine, implemented in FPGA technology, that makes it possible to perform all video analytics (full-image individual passenger tracking) on the sensor itself. Since the whole processing is performed on the sensor, no video streaming is necessary, and data privacy is guaranteed. Compared to normal video technologies, the 3D technology is much more robust.

Features of the Xovis 3D Technology

Data streams sent out by the sensor are so-called “Dot Streams”, meaning a constant stream of moving dots, in which the dots represent moving coordinates for every single passenger.

Live View

All tracked persons are visualized as moving dots on a still background image in real-time. The actual situation can be supervised. All applications, such as People Counting and Waiting Time Measurements are based on this tracked data.


All tracked data can be recorded and stored in the database, and the “Dot Stream” view can be replayed later for in-depth analysis of critical Passenger Flow Situations.


To increase visibility range of a single sensor, Xovis developed the Multisensor Technology: several sensors with overlapping viewing ranges are combined to cover larger areas. In the total area, an overall person tracking is performed.

Xovis XS Software Suite

The all-in-one Software

The XS Suite is a Windows server-client software, which receives the data streams (no video, just moving coordinates for every single passenger) from all sensors. Calculated on these streams are KPIs, including Waiting Times, Process Times and People Counting. Thresholds and Service Levels can be set and monitored. Provided alarming functions help to get notified.    

Capabilities of the XS Suite

The Xovis XS Software Suite supports a PDCA (Plan–Do–Check–Adjust) like cycle for the continuous monitoring and improvement of Passenger Flows and Processes:


all KPIs, all over the airport, 24/7, with the highest accuracy and stable sample rates of up to 98%.




the number of arriving passengers and waiting times, as well as recommendations regarding number of lines and desks to open in order to meet with certain Service Level Agreements.




Passenger Flow and resources before long queues occur, be one step ahead.




overall airport performance, increasing passenger experience and lowering operations costs.



Xovis Server

The XS Server receives the data streams (no video, just moving coordinates for every single passenger) from all sensors. Databases can be used for configuration data, measurement data and streaming data. The server software has a base layer that features sensor and multi-sensor management, configuration as well as visualization and outputs the tracking data. On top of the base layer, different application modules can perform the required algorithms to calculate waiting times and similar features based on the tracking data.  The reporting functionality of the XS Server is based on Excel templates, which can automatically be refreshed and sent to email recipients.

Xovis Clients

Exemplary Use Cases

Check-in Waiting Time and Process Time Measurement

Accurate KPI measurement is a key competence of Xovis PTS. Currently, no other system on the market manages to measure check-in processes as accurate as our sensors. Any unstructured area without defined entry and exit points, where passengers, “meeters and greeters”, visitors, and staff come together are analyzed precisely by the Xovis PTS.

  • Total area coverage
  • All queues in area automatically detected 
  • Queues are allocated to relevant desks 
  • Waiting times and queue length stored per desk
  • Detected queues are visualized in real-time
  • Display of allocated desks
  • Separates queues before check-in 
  • Display of waiting time, fill level and two configurable KPIs for each queue 
  • Daily desk allocation view can be compared with planning data 
  • Performance reports for individual stakeholders can be generated
