Passive WIFI Sensors

The newest member of the ARM Passive Wifi Sensors are discrete and will not look out of place at your activation/store/location. The previous version of the ARM sensor “TPLink MR3020” is no longer supported since ARM V2 and the GL-Inet custom sensor is the only passive WIFI sensor compatible with the features of ARM V5.

Meet the Passive WIFI Sensors

We have obsessed over the whole platform to make it as easy as possible to deploy and the Sensors are no different. They are so easy to deploy your grandparents can do it.

The sensors allow clients to use them as transient installs or as permanent installs. We even have clients who use them in the brand ambassador’s backpacks for full mobile tracking.

The sensors use the WIFI interface to listen unlike some of our competitors we DO NOT transmit data back to our servers using WIFI. We can transmit data via a built-in 4g/LTE modem, Ethernet or we can even store the data encrypted on an SD card in the sensor itself allowing clients FULL flexibility if there is no connectivity available on-site


  • Portable self contained
  • Multiple ways to send data to the ARM servers
  • Built-In 5,000mah Battery
  • Off-line Storage
  • Hybrid mode (store locally on SD card transmit data at regular intervals)
  • Data is encrypted by the sensor and can only be decrypted by the very same sensor
  • Can be power from Mains or external powerbank
  • Consumer-grade hardware tried and tested in numerous environments
  • Credit-Card sized footprint (very discrete)
