PROTECH’s dual sensors incorporate either unique single Stereo Doppler Microwave system (with two receivers for lowest level of false alarms) or dual where it is combined with Dual Element Infrared Detector. There are many other motion sensors in the market, but Protech works outdoors.These sensors are unique in that they provide reliable outdoor volumetric protection under even the most severe environmental conditions. The detection parameters are already to enable these sensors to offer greater overall detection capability for slow moving, fast moving and crawling intruders. Stereo Doppler is the key to Protech motion sensors unique false alarm immunity caused by animals and birds. The range of Protech outdoor motion sensors consists of equipment for medium security applications which is used mainly for ladders and towers protection; equipment for high security applications such as protection of strategic areas or assets; and explosion proof sensors which are installed at petroleum refineries, chemical and petrochemical plants, storage areas and other hazardous material processing facilities.AIS is also distributing Fiber Sensys solutions which are resistant to most environmental effects (EMI, RFI, wind, extreme temperatures, lightning and other weather-related conditions). They are widely used on chain link fences, non-climb fences, rooftops, walls, etc. Fiber optic sensor cables cannot be detected when buried below the ground or embedded in a wall and can cover perimeter zone up to 20km. Fiber SenSys high-security solutions have undergone rigorous testing by Sandia National Laboratories and the US Air Force. As a result, these products have been approved for use in programs such as TASS, IBDSS, Protected Distribution Systems, and the Nuclear Active Seals program.Both Protech and FiberSenSys have highest accreditations in the US, both were approved for Priority Level 1 (Nuclear) sites by Department of Defence. Currently being tested by SCEC in Australia, they offer proven and reliable technology to Australian customers.
