Autonomous avalanche detection systems

The avalanche radar detects avalanches reliably at day/ night and in fog and snowfall even 5 km away.

Automatic road closures in real-time

Radar systems monitor several mi² for avalanches, debris flows or rockfall and automatically close traffic routes within seconds.

Monitoring at 4133 m a.s.l.

Our highest station monitors the Weisshorn hanging glacier with a deformation camera and detects instabilities at an early stage.

High resolution cameras

Live and past images with a resolution of up to 40 megapixel for automatic deformation analysis.

 hazard zone via the online portal.

Glacial lake monitoring systems

Comprehensive monitoring system for glacial lake, drainage channel and outflow including alarm for Plaine Morte Glacier.

Deformation analysis based on HiRes images

Autonomous system solution for remote monitoring of landslides and rock instabilities.

Avalanche radar Zermatt

The avalanche radar system in Zermatt reliably detects avalanches and automatically closes the access road.

Radar system monitors Pizzo Cengalo, Bondo

Geoprevent installed a radar system above Bondo. The radar detects millimeter-movements and warns early.

Monitoring of dangerous glaciers

Bis glacier: Combined system of two deformation cameras and an avalanche radar with a record range of 5 km.

Online data portal

Our online data portal shows live data and past events.

Motion sensors

Lower maintenance costs for rockfall protection barriers as well as increased safety due to alarm functionalities.

Rockfall radar

More than 1 km range and a coverage of 1 km². All-weather suitability.


The interferometric radar detects smallest movements and acts as early warning system for rock instabilities and permafrost.

Cleft measurements

Extensometers and telejointmeters measure clefts with submillimeter precision. Easy and fast installation.

Level measurements

Radars, laser measurements and pressure probes provide useful data about the flow.

People radar

The radar detects people in the hazard zone. In all weather conditions and during day and night. Alerts are triggered automatically.

Innovative Technology

We use cutting-edge technology only to develop our alarm and monitoring systems.

Online Data Portal

All live measurement and system status data are displayed digitally and can be accessed by authorized users at any time.

Alarm and Monitoring

We alert reliably by priority SMS, email or phone calls. Roads are closed automatically by traffic lights or barriers.

What do our customers say?

“The AADS (Autonomous Avalanche Detection System) supports us considerably in assessing the current avalanche situation and enables us to better understand the regional avalanche conditions. As a result, we have been able to verify the accuracy of our forecasts and significantly reduce closure times of the highway by more than 40% of the annual average this season.”Ryan Boyle
District Avalanche Supervisor
Ministry of Transport and Infrastructure

“The alarm system works very well! It supports us in monitoring the road Taesch-Zermatt. Every single avalanche movement in the area is shown which let’s us assess the situation a lot better.”

During critical weather situations, we can rely on the alarm system and no longer have to be on constant alert. The different measurements allow us to learn more about the characteristics of the Carrera creek and to assess situations even better in the future.

“The avalanche and people radar installed on Belalp in December 2018 convinced us very quickly and made our work much easier. The real-time information and images provide us with the data and information we need before, during and after an avalanche blast, which helps us make the right decisions.”
