Remote monitoring is achieved even in places where mobile phone signals do not reach, such as underground or in tunnels, through our unique multi-hop wireless UNISONet. There is no need for power supply preparation or wiring work at the measurement points. With simple installation work, the total cost is less than half compared to wired systems. We provide this system along with a cloud-based management solution that can be accessed remotely. *For more details, please refer to the PDF document or feel free to contact us.

A wireless network that operates with low power consumption enables multi-point synchronized measurements throughout large structures such as high-rise buildings, as well as remote monitoring in underground areas and tunnels. Wiring work and power preparation at measurement locations are unnecessary. Thanks to smartly designed devices and simple installation procedures, total costs can be reduced to less than half compared to wired systems. We provide a remotely operable management system via the cloud, achieving efficient operation. Our wireless network, responsible for communication and time synchronization, utilizes our proprietary LPWA technology "UNISONet." *For more details, please refer to the PDF document or feel free to contact us.*

Today, I have some exciting news for everyone. Our "Wireless Tilt Monitoring System" (NETIS Registration Number: KT-230117), which is registered with the Ministry of Land, Infrastructure, Transport and Tourism's NETIS (New Technology Information System), has successfully had its registration details changed and approved. Some of you may be wondering what’s so great about this, but with this change, all systems equipped with UNISONet are now eligible technologies for NETIS registration. In other words, this opens up opportunities for our technology to be utilized in even more fields moving forward. *You can view the detailed content of the blog through the related link.
