What people say about LAIIER

  • "If we’d had LAIIER’s water detection system in place, we could have learned about the issue in minutes instead of days. While we have systems in place for emergencies, we only take action if we know there is a problem. We had a room out of action for weeks, which could have been avoided with LAIIER’s solution.”

  • “For property claims, water damage continues to be the predominant cause of loss. While many water damage control solutions focus on water leaks from building piping, LAIIER can detect the presence of water anywhere, especially in odd shaped spaces, making it a useful tool for detection of water intrusion, as well as water release."

  • "We believe that sensors for remote monitoring, such as the LAIIER leak detection sensor, represent an important preventative measure towards potential unforeseen damage, and can help to improve work safety by early detection of wet floors.”

  • "LAIIER’s commitment to the evolution of LoRaWAN standard, certification of devices, and collaboration with ecosystem partners will be an asset to the alliance and further the global adoption of LoRaWAN across all industries.”

  • "By bringing data from a physical to a digital domain, LAIIER gives building managers, facility operators, infrastructure owners, and insurers clarity on the health of their buildings. The LAIIER team has built technical expertise that lets them put sensors where others cannot, collect data others can’t access, and ultimately paint an accurate picture of building health that others can’t see."

  • "Overall, installing the sensors is very easy. As they come in the form of a sticky tape, they can be mounted almost anywhere, even in hard-to-reach places, and are resistant to spills and perfect for high-traffic areas."
