There is an object suspected of an infrared sensor on the wall at home! What is this for? Why did people who used to live here press this button ~

The infrared sensor installed on the home wall is a kind of intelligent home security system. Home intelligent security system is harmless to human body.

The home security alarm system consists of a security center management host, a home alarm, various sensors and transmission cables. Various sensors are deployed in important places and areas of the family, and sensors can replace the traditional steel anti-theft net in the family. When the owner goes out, he can turn on the anti-theft system (protection) through the keyboard operation of the intelligent control host, and then lock the door and leave (it can also be protected by the wireless remote controller he carries with him).

When the owner goes home, he only needs to enter the password on the intelligent control host to disarm the anti-theft system (anti-theft), and then when the owner is at home, the indoor infrared detector and the door magnetic switch will stop working to avoid false alarm (or the anti-theft can be disarmed by the wireless remote controller that he carries with him). When sleeping, you can also protect the designated area. If residents forget to evacuate/deploy when they go out, they can also evacuate/deploy remotely by phone or computer.

Working principle of home intelligent security system

After the residents turn on the intelligent security system, when someone illegally breaks into the house or opens the glass window to sneak into the room, the infrared detector installed on the door or window will automatically detect the intrusion signal and immediately send it to the powermax host, which will automatically start the acousto-optic alarm system and transmit the signal to the monitoring system of the monitoring management center through the intelligent security control host.

An alarm prompt appears at the corresponding position of the floor plan on the computer monitoring screen, showing which building and room of the household has what kind of alarm, and notifying the corresponding personnel to rush to the scene. Residents can also protect the system at home, especially when sleeping at night, and the system can also ensure safety. At the same time, you can also press the portable wireless emergency help button to send out distress signals such as fire, police theft and medical treatment to the monitoring center.

The emergency help button and the alarm of the gas leak detector are not controlled by passwords, and they are on alert for 24 hours. Powermax+ intelligent security control host can also have multiple computer expansion interfaces. Residents can directly connect to computers and surf the Internet through information transmission networks. If there is no network, it can also be transmitted to your mobile phone through GSM mobile phone network.
