Microwave barrier 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, it begins a detailed analysis of the situation that, if considered a real intrusion, provides an alarm be treated in digital form. The difference of Microwave Barrier and infrared barrier is the protection area and environment endurance. On these two aspects, Microwave Barrier performs better than Infrared Barrier. Microwave Barrier can form a cubic protection space and not just a space is about 2.5m *5m and can be adjustable. Microwave Barrier can be installed at wall or fence of military sites, air port, power plants where high security requirement is needed. MCB-150 is hard and Microwave Barrier.
