The ALS incorporates two Laser Range Finders (LRF) assembled in a sealed housing. Both LRF rotate on a common axis. ALS creates a double virtual detection fence. While rotating the LRF transmits laser pulses at a rate of 6000 p/sec. The return pulses are detected by the LRF.
ALS processes the data and creates a virtual map of the protected area by measuring the distance to the surrounding objects.
It covers a circular area up to a maximum of 700 m in diameter. It can detect walking, running, crawling and swimming intruders. It is used at highly sensitive sites.
