Barriers or microwave sensors can detect intruders walking, running or crawling in outdoor environment. Southwest Microwave sensor developed the first bi -static microwave industry in 1971, and has pioneered the development of reliable and flexible links and microwave transceivers for protecting open areas , doors and entrances and applications for roofs or walls.
Microwave sensors generate an electromagnetic field (RF) between the transmitter and the receiver, creating an unseen volumetric detection zone. When an intruder enters the detection zone, the changes in the field are recorded and an alarm occurs .
Our microwave barriers provide a high probability of detection, low level of unwanted alarms and excellent resistance to rain, fog, wind, dust, snow and extreme temperatures. Most models used by Smartech Security operating at K -band frequency, which maximizes performance and minimizes interference from external sources of radar.
The photoelectric sensors consist Infrared addressed linearly along the perimeter and its implementation is very similar to microwave barriers, however the main difference between the two, apart from the detection technology is that the light barriers are less immune to unwanted alarms generate microwaves barriers. Also the light barriers for linear deployments are 650 feet or less, while microwaves can reach much greater distances, however its main advantage is its low cost and low diversity of models and wide range for both exterior and interior.
