Precautions for installation of passive infrared detectors

1. Installation height

Installed according to the height indicated in the product manual. If the height is not installed correctly, it may cause the detection distance to be shortened. For pet-proof products, the effect of pet-proof may be affected.

2. Installation angle

Some products indicate the installation angle in the manual, which has a great relationship with the optical system of the product. If the installation angle is incorrect, it may affect the detection area.

3. Installation location

· Avoid installation in places where the temperature changes frequently;
· Avoid installation in places with large air flow;
· Avoid installing directly against glass doors and windows;
· Avoid direct swinging objects;
· Avoid close to air conditioners, electric fans, refrigerators, ovens and objects that can cause rapid temperature changes;
· Avoid installation in direct sunlight.

Because the working principle and characteristics of passive infrared detectors are likely to cause misjudgment of the detectors and cause false alarms in these positions, you should try to avoid installing in places where these phenomena exist during the installation process. The more reasonable installation location is generally in the corner of the house. The advantage of this installation is that the detector range is relatively large and it is not easily interfered.

4. Installation direction

The product also needs to pay attention to the installation direction during the installation process. Since the optical characteristics of the lens determine that the cross-sectional detection area is more sensitive, the angle between the intrusion direction and the detector's field of view should be noted when installing the product. It can ensure that when someone invades, it can cross the detection area to the greatest extent.

With the rapid development of electronic technology and the continuous improvement of digital technology, passive infrared detectors will increasingly use digital technology to solve existing problems, and the functions of passive infrared detectors will gradually improve , Will be further favored by users.
