How should infrared detectors be installed.
Infrared detectors are commonly used in security engineering. They use advanced signal analysis and processing technology to provide ultra-high detection and anti-false alarm performance. When an intruder passes through the detection area, the infrared detector will automatically detect the movement of the human body in the area. If there is dynamic movement, the infrared detector will send an alarm signal to the control host. However, due to the diversity of the environment, it is necessary to understand some basic concepts and technical characteristics of infrared detectors not only for normal use, but also for preventing false alarms and reducing false alarms. So, in the process of installing the infrared detector, how to install it correctly?
1. Please install and use correctly according to the instructions The installation height of the infrared detector is not arbitrary, which will directly affect the sensitivity of the detector and the effect of anti-pet. If the requirements are higher, a detector with anti-pet function can be installed. At the same time, do not touch the surface of the sensor, so as not to affect the sensitivity of the detector. To clean the sensor, please disconnect the power and wipe it with a soft cloth dipped in a little alcohol.
2. Selection of installation location Install infrared detectors where intruders can easily pass. The mounting surface should be solid and free from vibration. Avoid installing it outdoors, near air conditioners, near heat sources and in direct sunlight, or under rotating objects. The induction function of the passive infrared detector is closely related to the change of temperature, so the installation location must be selected well. At the same time, do not face the glass doors and windows when installing. There are two problems when facing glass doors and windows: First, white light interference. Although passive infrared detectors (PIR) have a strong suppression function for white light, it is not 100% suppression after all. Do not face the glass doors and windows to avoid the interference of strong light. The second is to avoid complex environmental interference outside the doors and windows, such as direct sunlight, crowds, moving vehicles, etc.
3. Remove the shell screws, open the front cover, and install the battery in the correct direction. In order to ensure that the infrared detector can work normally, the power supply of the detector should be maintained, and the walking test must be carried out periodically, and it is recommended to do it once a week.
4. Fix the mounting bracket to the wall with screws and hang the detector. After installing the infrared detector, debugging the detector is the last thing to do. The debugging of the passive infrared detector is generally a walk test, that is, the debugging personnel walk the S-shaped line in the warning area to perceive the length and width of the warning range to test whether the entire alarm system meets the requirements. If the sensitivity of the detector is too high or too low, make appropriate adjustments according to the instructions.
In conclusion, although infrared detectors can reduce the occurrence of theft, they are not foolproof. In order to be safe, in addition to using it correctly, it is also necessary to be vigilant in daily life and strengthen the awareness of safety precautions.
