When Radiobarrier security systems were operated in complex, industrial noise environments such as close to railway tracks or pierces, seismic sensors used to generate false signals and thus hampered intruder detection. Besides, seismic sensors did not respond to infringements on some types of soils such as dry cracked soil or plots of lava spillage or former marshes.
Uniscan Research has developed RSL 433 radio sensor that makes it possible to secure irregularly shaped territories. The sensor got its name because it used the frequency of 433 Hz - no permits are required to use this frequency. Besides, this frequency emission is easily blocked by usual metal-mesh fences as wave length is bigger than mesh cell size.
RSL has a high factor of safety: The sensors were tested in extreme weather conditions such as constant rains and electrically charged air as well as on clayed soils and crushed stone. The sensor is equally efficient with concrete and asphalt, grass and bushes and even under the snow cover.
Besides, high sensitivity allows the sensor to cover unconventional landscapes and properties such as hills and complicated tubes. RSL, like the other components of Radiobarrier portable security systems, is wireless and optimized for years of autonomous operation.
