Operation

The basic principle of operation consists of detecting the frequency shift between a transmitted and a

received signal reflected back from a moving object within the field of view of the unit.

The unit produces a low level IF output signal which can be amplified and processed to provide an

audible or visual alarm signal and employs low cost surface mount manufacturing techniques which

are field proven as being rugged and reliable.
