BM 120 HP Digital Microwave beams

The BM 120 HP digital microwave beams are reliable intrusion detectors used for exterior perimeter intrusion protection. The digital technology provides a better connection between devices, as well as fast RS485 and USB serial connections.

BM consists of 2 units - 1 transmitter (TX) and 1 receiver (RX) - installed at a maximum distance of 120 meters. The transmitter continuously emits microwaves to the receiver. When an intruder passes between the two units, the received signal is consecutively reduced, and when it reaches the alarm level, the alarm is triggered. Additionally, these barriers allow for the detection and signaling of accidental and permanent beam interruptions.

The BM integrates flat antennas that reduce the sensitivity area by 20% compared to the old parabolic antennas. BM can be installed at greater distances for the same perimeters, saving costs. Additionally, to protect against rain, parabolic antennas use large, cumbersome waterproof housings, while BM's flat antennas are highly protected by tropicalization and installed in high-resistance protective covers that prevent condensation and the development of rust.

These microwave barriers are placed in specially designed containers to tolerate and facilitate delicate installations. They operate in all weather conditions (snow, rain, fog) without reduction in distances, unlike active infrared barriers. If the temperature drops below -5°C, a TERM barrier kit can be installed.
