For over 20 years Protech has provided military, government, commercial, and industrial users the highest standard in intrusion sensors. Protech's commitment to excellence and innovation helps assure unique solutions for your security requirements.
In 1980, a technological breakthrough in microwave signal processing, termed Stereo Doppler, was developed. This technology was the basis for Protech’s high security military motion sensor switch designs. Protech now utilizes this proprietary auto transport dual-channel microwave design in all of its intrusion sensor products. Stereo Doppler is the key to Protech commercial motion sensors unique false alarm immunity.
