The qastle Smart Alarm™ system allows homeowners to easily upgrade a traditional wired alarm to a modern, full featured smart system simply by replacing the control panel of the existing system with the qastle Smart Alarm Controller. There is no need to invest in new sensors – reuse all of the existing sensors, keypads and devices simply by moving the wiring for these from the old system to the qastle Smart Alarm Controller. The qastle Smart Alarm Controller utilizes LTE-M powered by Sequans’ Monarch Go for reliable connectivity ensuring the qastle app for iOS and Android can communicate with the Controller and provide full control and visibility from anywhere on the planet.
