Innovating the market since 2004

Our innovation platform goes back to 2004 back when we were developing high-quality security systems. As an innovator in wireless alarms, most of our efforts was developed in two technology areas:

Security - to enable identification of disturbances and secure data flows.

Power efficiency - to transmit a lot of data (climate, visual) on high- and low bandwidth, while using ultra low power usage. Want to read more about why our innovation approach matters?

  • Stockholm stad logo

    Better air quality in Schools

    Stockholm City has installed 3.000 of Lansen’s CO₂ sensors across all high schools in Stockholm. Through easy installation and AI management, the indoor climate is now under control - improving the air quality every day for 10,000 youths and simultaneously reducing the energy consumption. - SISAB, Stockholm City’s Schools
  • overview repeater coverage in the municipality of Alingsås

    100% coverage and fewer units - with Lansen’s Repeaters

    In the municipality of Alingsås, Sweden, all water meters are remotely read every hour. Our customer had problems to collect data from meters out of free sight placed in basements. The solution, the Lansen OMS Repeater that pushes the measurement values from the meters in a multi-hop chain to the Gateway. The results? 100% coverage and a satisfied customer.
  • Digitise your residential buildings with metr

    Digitizing and reducing CO₂ emissions in Berlin

    Metr Building Management Systems GmbH, a PropTech from Berlin in Germany, use the sensors from Lansen to digitize older analogue heating and hot water systems and are connected to the intelligent platform “the m-gate”. The sensors expand the measurement points and collect a more substantial amount of data - for real time tracking, optimizing the energy consumption and possibility to repair damages before the tenants' living comfort is affected. By digitizing the systems, metr supports the housing industry in operating their buildings more energy-efficiently and reducing CO₂ emissions.
