The SignalFire Remote Sensing System™ is a flexible adaptive radio networking system that seamlessly integrates analog and digital sensors. With a range of up to 3 miles, the system is self installing and self configuring. All the installer has to do is set the check-in frequency using a simple rotary switch, record the radio address, and connect the sensor. This system compares very favorably, from a cost perspective, with installed conduit at distances of 100 feet or more.
