A microwave barrier is one of the most reliable and safe intrusion detectors used for outdoor perimeter protection.
Microwave barriers operation
The operation of a microwave barrier is very simple. This type of device develops an electromagnetic beam using high frequency microwaves that passes from a transmitter to a receiver, creating an invisible but sensitive protection wall. When the receiver detects a difference of condition within its beam (and hence a possible intrusion), begins a detailed analysis of the situation that, if considered a real intrusion, provides an alarm signal that can be treated in analogue or digital form.
Use of microwave barriers
For high security, as for the perimeter protection of prisons, power plants, refineries, military sites and airports, it's normally chosen a digital product for analysis "fuzzy logic" that, besides providing a higher level of security, offers a remarkable ease of use and ease of maintenance, even remotely.
These products are often used for civilian and commercial applications as for the perimeter protection of villas, balconies, terraces, small industries and shopping malls.
