Wireless open/closed sensors provide information on the status of doors, windows, cabinets, etc. Know if a building or area is being accessed when it should not be, or if a door or window has been left open. Alerts can be setup to notify a user by SMS text, email or voice call if a door or window has been opened or left open. Know if a cooler or freezer door is left open.

  • Leading Enterprise Grade "Internet of Things" Solutions
  • Sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,200+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allow these sensors to have better interference immunity from other wireless devices.
  • Superior power management provides sensors with almost twice the battery life of standard wireless sensors.
  • Coin cell sensors typically last 3+ years.
  • AA and Industrial sensors typically last up to 12+ years.

Our products employ new Encrypt-RF® Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.


Integrated on-board data storage allows sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.

Over-the-air updates allow products to be updated remotely if new fixes or features become available.
