Other microwave sensors operate in analog mode. They simply look for a significant disturbance in the microwave signal to create an alarm.
The MWxPRO digital microwave protection sensors only start their work when a disturbance is noticed. Looking at the wave pattern generated while the disturbance is occurring, they decide if it is a real alarm or a nuisance event that can be ignored. How do they do that? Using “fuzzy logic”, the size, shape and rate of change of the observed signal is compared to hundreds of stored patterns corresponding to known alarm types. If there is a close match, an alarm is generated. Intruders walking, running or rolling will be caught. All disturbances, whether or not they are recognized as alarms, are date and time stamped and stored in the receiver for later analysis.
What kinds of things don’t cause nuisance alarms when you use these sensors, even though their sensitivity is set high? How about small animals, birds, fog, and the reflection off pooled water? All of these can create alarms with old analog style sensors until you lower their sensitivity to a dangerously low level.
