I.I.S. 900 MHz Wireless Sensor Monitoring System
The only wireless sensor platform on the planet with 12+ year battery life and over 1,200 feet wireless range (non-line-of-sight). 900 MHz products use frequency-hopping spread spectrum (FHSS), that are frequency-agile, providing better RF interference immunity in the most demanding applications. Integrated on-board data storage allows for days, weeks or months of time-stamped data logging. Over-the-air (OTA) updates allow IIS products to be updated remotely making them future-proof.
IIS sensor products use IIS new Encrypt-RF® bank level security, featuring a 256-bit exchange to establish a global unique key, and an AES-128 CTR for all data messages. So security is maintained at all communication points from sensor to base station, base station to software, and back again.
