[Infrared alarm function]
1ã€Infrared alarm has 100 independent wireless zones, which can be distributed alone. It is convenient and practical.
2, infrared detectors and the host can wirelessly code. Learning-style coding makes system expansion easier and faster;
3. The alarm sound and volume of the infrared alarm can be freely selected to enhance the alertness of the security system;
4. The host of the infrared alarm has the function of setting the time of the switch and the state of the boot and shutdown.
5, infrared alarm can display alarm information to facilitate the security personnel to alert the specific location and time of the alarm;
6, infrared alarm can check the alarm records, with storage function;
[Infrared alarm installation method]
The external alarm is an alarm system composed of an alarm host and an infrared detector. The infrared detector is a weak signal detection device. Therefore, when installing, it is necessary to pay attention to details such as sensitivity and height. How to install a passive infrared detector? It must be done in the following steps:
1, the performance of the infrared detector must be particularly aware of, this is the basic work of the installation of the alarm;
2, determine the installation location of the installation of infrared detectors, this is a high problem;
3, must be careful to the infrared detector debugging, debugging his sensitivity, which is the key to installation.
Height adjustment:
How to adjust the sensitivity of this debugging? The height of the installation affects the detector's sensitivity. The difference in height of the detector, the frequency of the cutting area and the dark area will become different.
Environmental adjustment:
In addition to highly affecting the sensitivity, the surrounding environment of the infrared detector also affects its sensitivity. For example, if the passive infrared detector is facing the glass doors and windows, then there will be two problems: one is the environmental interference outside the doors and windows, the crowd and the flow of vehicles will affect the detector's judgment of the signal; the other is the white light interference. The PIR of the infrared detector has a strong suppression function for white light, but this is not completely suppressed, so avoid facing the white light source and avoid glare interference.
Temperature adjustment:
Infrared detectors' passive infrared detectors' sensing is closely related to temperature changes. The hot and cold temperatures are likely to cause false alarms from infrared detectors. If they are low-performance detectors, air convection in windows and doors can also cause false alarms. Therefore, it is necessary to select detectors with different sensitivities according to changes in the temperature of the environment. This is a point to consider when installing an infrared alarm.
Xiaobian epilogue: The above introduced the infrared alarm related knowledge, I hope to be helpful to everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.

In recent years, smart dimming glass has been widely used in home partitions, hotel bathroom partitions, office partitions and other scenarios. The glass itself has all the characteristics of safety glass, but also has the control of glass transparent or not privacy protection function. EC dimming glass has a slow response speed, which may be as long as several minutes. PDLC has very limited thermal insulation effect. Increasing the thermal insulation effect can add a layer of low-E glass, while SPD and EC technologies have good thermal insulation effect.Due to the relatively high operating voltage, the application scenarios are relatively limited due to the consideration of security risks, and are relatively rare in China. PDLC has two basic states: transparent and atomized. Even if glass atomized, a lot of light will pass through, that is, transparent but opaque. PDLC can also create transformable transparent or atomized graphic effects on glass, with good design and expansion properties. EC and SPD can continuously adjust the rate of light passing between transparent and colored states, but cannot design graphic effects.
