Key points for the installation of various detectors

AVE GURNEE, Ill. - April 16, 2024 - PRLog -- Microwave motion detector
(1) The penetration of microwaves to non-metallic substances has both good and bad sides. On the plus side, several rooms can be monitored with a microwave detector, and it can also be camouflaged with additional modifiers for easy knocking installation. The bad side is that if the installation is not adjusted properly, people walking outside the wall or vehicles traveling on the road and trees shaking outside the window may cause false alarms, the solution is mainly: the microwave detector should be strictly prohibited to install the outer wall and window of the protected room, and at the same time, the control range and its directivity of the microwave detector should be adjusted during installation. Usually the alarm detector is suspended at a height (1.5-2m from the ground), the probe is slightly downward, so that it points to the ground, and the detection coverage area of the detector is limited to the area to be protected. This minimizes the adverse effects of penetration performance.
(2) There should be no oversized and thick objects, especially metal objects, in the monitoring area, otherwise there will be a blind zone for detection behind these objects.
(3) Microwave detectors should not be quasi-fluorescent lamps, mercury lamps and other gas discharge light sources. The 100Hz modulated signal directly generated by the fluorescent lamp can cause false alarms, especially if the faulty flickering fluorescent lamp is more likely to cause interference. This is because the ionized gas in the flashing lamp is more likely to become a moving reflector of microwaves and cause false alarms.
(5) When more than two microwave detectors need to be installed in the same room, the microwave emission frequency between them should be different (usually about 25MHz difference), and should not be placed opposite each other to prevent cross-interference and false alarms.
(6) The probe of the microwave detector (https://vedardalarm.com/microwave-barrier-mcb150-outdoor-...) should not be aimed at the objects and parts that may move. Otherwise, these objects can become moving targets and cause false alarms
(7) The microwave detector should not be directed at large metal objects or objects with metal plating, otherwise these objects may reflect microwave radiation energy to the sidewalk or road of the exterior wall or exterior window. When pedestrians and vehicles pass by, the microwave signals reflected back by them may be reflected to the probe again through these metal objects, causing false alarms.
(8) Radar microwave detectors are indoor application detectors. When applied in outdoor environments, the reliability of its detection cannot be guaranteed.
