The outdoor infrared detector is an active anti-theft detector with excellent performance. It is mostly used for anti-theft places such as walls and straight lines or planes. The outdoor infrared detector works very well and works very well, but if it is installed professionally, it can not only play the role of anti-theft, but often false positives or false negatives, thus delaying normal warning. The following Xingwang engineers and technicians share their experience based on years of installation experience for everyone to read and refer to.
Outdoor infrared detectors mainly have the following installation methods.
Wall-mounted installation: Now the manufacturer of active infrared detectors at the forefront of the anti-theft market, can provide infrared detectors with a horizontal angle of 180° and a tilt angle of more than 20°, such as ALEPH active infrared detectors HA, ABT, ABF The series products can support the probe to be installed directly on the outer wall of the building or on the fence and fence.
Pillar installation: The more popular pillars are round and square. Mainly the detector is mounted on the square pillar without rotation and is not easy to move. In addition, a wide range of stainless steel, alloy, aluminum alloy profiles are also one of its advantages. Another method on the construction site is to use angle steel as the pillar. If the trace is not guaranteed to be effectively worn, the line is exposed in the air. The shape of the pillars can be "1" shape, "Z" shape or curved, depending on the characteristics of the building and the anti-theft requirements. The key point is that the pillars must be firmly fixed without displacement or shaking to facilitate installation and Fortification and reduce false positives.
General principles for the installation of outdoor infrared detectors
The main function of the detector set on the wall is to prevent man-made malicious over-the-counter, both top and side mount. The detector mounted on the top should be positioned higher than the fence and 25C M at the top of the wall to reduce false alarms caused by birds and kittens moving on the wall. The anti-false alarm capability of the 3 beam detector is stronger than that of the 2 beam, and the 2 beam is stronger than the single beam.
The detector set on the channel is mainly used to prevent illegal passage of people. In order to prevent false alarms caused by pets, small animals, etc., the position of the probe should generally be more than 50C M from the ground. The shading time should be adjusted to a faster position to respond quickly to illegal intrusions.
The side installation is to install the probe on the fence, the wall is close to the top side of the wall, generally for wall installation, mostly installed on the outside. This way can avoid the interference of birds and kittens.
Each method has its own advantages or disadvantages, and the engineering firm has their own preference for each type of installation of outdoor infrared detectors . Users should choose according to the characteristics of their buildings and anti-theft requirements.
