DUO
200
is
a
state-of-the-art
microcomputer controlled dual-
technology intrusion detector. Its operation is based on two
physical phenomena - the infrared (IR) radiation emitted by the
human body and the Doppler frequency shift caused by a person
moving in a microwave (MW) field. The IR and MW technologies,
when combined in a single detector, complement each other to
assure the most reliable detection and immunity to false alarms.
The superiority of the DUO 200 over other dual detectors has
been achieved by the advent of the
True Motion Recognition™
algorithm
(patented). This advanced motion analysis method
provides the DUO 200 with the ability to distinguish between the
true motion of a human body and any other disturbances which
invariably cause false alarms.
Another unique feature of the DUO 200 is the
MW Motion
Simulator
circuit (patents applied for), which simulates the effect
created by a human body moving in the MW field. The simulation
routine is carried out periodically for self-testing, supervision and
assurance that the MW detector operates properly.
