For over 30 years Protech has provided military, government, and commercial users the highest standard in intrusion sensors.
In 1980, a technological breakthrough in microwave signal processing, termed Stereo Doppler, was developed. This technology was the basis for Protech’s high security motion sensor design. Protech now utilizes this proprietary dual-channel microwave design in all of its motion detector intrusion sensor
Doppler technology is the key to Protech's commercial motion sensors unique false alarm immunity.
