ADDITIONAL INFORMATION

CONFIGURABLE THRESHOLDS

Configurable high/low thresholds allow different transmit intervals when thresholds are crossed providing advanced edge intelligence to the network, and enable alarms to be generated by Realtime-Online™.
 

REAL-TIME MONITORING 

Data from every sensor in your network is reported back through Invisible Systems Big Data architecture either to our Monitoring and Analytics platform Realtime-Online™, or to a partner cloud platform via our API, ensuring that your data is visible, actionable and valuable to your organisation.
 

LORAWAN

The ISL LM1100 is a LoRaWAN certified device and Invisible Systems are members of the LoRa alliance. It offers both ABP and OTAA activation options and is designed to work with all LoRaWAN gateways and network servers.
