Murena Plus 12, 24, Curtain
1 DESCRIPTION
1.1 Product Description
Murena Plus is a volumetric microwave sensor that use Dual Doppler effect and digital
signal processing, for external protection.
The size and shape of the detection field make it particularly suitable for the protection of
areas completely free of obstacles or for irregular shaped areas with fixed obstacles
present.
Murena Plus is available in the following versions:
-
Murena Plus 12
-
Murena Plus C (Curtain 12m)
-
Murena Plus 24
Murena Plus can be used either as a “fan” pattern or as “curtain” (Murena Plus Curtain)
particularly suitable for covering the front of buildings.
Using this “curtain” it is important
that there are no indentations or protrusions that allow the intruder to pass quickly
through the very narrow microwave beam.
This product use appropriate algorithms in order to measure the distance and the mass of
the object moving in the detection field, analysing all the received data using “Fuzzy” logic
analysis.
This avant-garde approach means that most of the problems created by external
environments on mono-static microwave sensors (those with the transmitter and receiver in
the same head) can be overcome.
Finally, it is also possible to make remote functional tests, such that the proper operation of
the detector can be checked centrally.
The design includes a minimum range function to eliminate signals created by small objects
close to the detector and a maximum range function to de-limit the detector analysis area.
Set, for example, to 8m, the signal created by a human body at 10m will not be considered
for analysis in the generation of alarms.
