LIRIS : flexible, wireless, standalone monitoring



 LIRIS standalone wireless Optical Strand

The OSMOS standalone wireless Optical Strand is incorporated in the world of the Internet of Things for ad hoc, non-intrusive monitoring, including in zones that are difficult of access or in emergency situations. The wireless standalone Optical Strand has a compact mini-station that provides real-time detection and analysis of deformations based on 18 behavioural criteria.

Data recovery is done manually by OSMOS teams before the data are recorded and analysed in the OSMOS Cloud and become accessible from the client Web interface.

The OSMOS wireless standalone Optical Strand is easy to install and configure. It is compatible with visible and audible alarm systems and with the SMS alert system that remotely informs the recipient if the threshold is exceeded and sends a daily structural behaviour report.
