PROFESSIONAL MIRROR OPTICS PIR DETECTORS
PRECISION VARIFOCAL MIRROR DESIGN
Varifocal mirrors dramatically improve the focus and level of energy collected
by the Pyro Sensor regardless of range. The electronic gain of the detector is
reduced and therefore the Signal to Noise ratio is optimized to virtually eliminate
false alarms. This design also provides an improved freedom from false alarms
with its unprecedented level of immunity against visible light.
ASIC BASED SIGNAL PROCESSING
The ASIC signal processing implemented in the MR series allows the detector
to identify human movement with extreme accuracy, validate intrusions and
program itself to cope with harsh environmental applications.
EXCEPTIONAL STABILITY AND VERSATILITY
The MR series offers an unparalleled detection capability and stability for every
security installation. It includes various models adapted to each type of installation,
from the smallest device for curtain pattern protection to the most sophisticated
sensors.
