 Brief description of relevant equipment

1. ET8511 IP FAM alarm controller

It is the information collection and control terminal of all wireless sensors and wireless linkage control equipment. All sensors and detectors will transmit the collected information to authorized mobile phones, tablets, computers and other management devices through ET8511; In addition, some control commands are sent by the management equipment to the linkage equipment through ET8511.

For example, if the door is opened when there is no one in the house, and the door magnetic detector detects an intruder, the intruder alarm will be sent to the master's mobile phone through ET8511. The mobile phone will send a vibrating ring prompt after receiving the message, and the master will send a control command after confirmation. The electromagnetic door lock will automatically lock and trigger the wireless audible and visual alarm to send an alarm.

2. Wireless intelligent dimmer switch

This switch can directly replace the wall switch panel in the home. It can not only be used as a normal switch, but also has automatically formed a wireless sensor control network with all the Internet of Things devices in the home. It can send the switch, dimming and other instructions to it through the wireless gateway. Its significance is that the owner does not need to worry about whether all the lights in the home have forgotten to turn off after leaving home. As long as the owner leaves home, all the lights that have forgotten to turn off will automatically turn off. Or when you sleep, you don't need to check whether the lights are on room by room. All you need to do is press the sleep button installed at the head of the bed, and all the lights will automatically turn off. At the same time, when you get up at night, the lights will automatically adjust to soft, so as to ensure the quality of sleep.

3. Wireless temperature and humidity sensor

It is mainly used to detect indoor and outdoor temperature and humidity. Although most air conditioners have temperature detection function, due to the volume limitation of the air conditioner, it can only detect the temperature near the air conditioner at the air outlet, which is also an important reason why many consumers feel that their temperature is inaccurate. With the wireless temperature and humidity detector, you can know exactly the indoor temperature and humidity. Its practical significance is that when the indoor temperature is too high or too low, the air conditioner can be started in advance to adjust the temperature. For example, when you are on the way home, the wireless temperature and humidity sensor at home detects that the room temperature is too high, and the air conditioner will start to automatically cool down. When you go home, the home is already a pleasant temperature. In addition, the wireless temperature and humidity sensor is also of special significance for you to go out in the morning. When you stay in an air-conditioned room, you have no sense of the outdoor temperature. At this time, the temperature and humidity sensor installed outside the wall can play a role. It can tell you the current outdoor real-time temperature. According to this accurate temperature, you can decide your clothes, without the embarrassment of wearing more or less after going out.

4. Wireless smart socket

It is mainly used to control the switch of household appliances. For example, it can automatically start the exhaust fan to exhaust. This is an interesting application for closed garages in hot summer. Of course, it can also control any household appliance you want to control, just plug the plug of the household appliance into the wireless intelligent socket, such as the water dispenser, electric water heater, etc.

5. Wireless infrared repeater

This product is mainly used for devices that can be controlled by infrared remote control in the home, such as air conditioners, electric curtains, televisions, etc. Through the wireless infrared repeater, you can remotely control the air conditioner wirelessly, and you can also close the curtains without getting up. This is a very meaningful product. It can immediately convert traditional household appliances into smart appliances.

6. Wireless infrared intrusion detector

This product is mainly used to prevent illegal intrusion. For example, when you press the wireless sleep button at the head of the bed, not only the lights will be turned off, but also the wireless infrared intrusion detector will be activated for automatic defense. At this time, once someone intrudes, an alarm signal will be sent out and the lights in the intrusion area can be automatically turned on according to the settings to scare off intruders. Or when you leave home, it will automatically set up defense. Once someone breaks in, it will automatically remind your mobile phone through the wireless gateway and accept the alarm processing instructions sent by your mobile phone.

7. Wireless air quality sensor

The sensor mainly detects whether the air quality in the bedroom is turbid, which is very important for you to go home and rest, especially for families with infants. It tells you whether the current indoor air affects health by detecting the air quality, and can activate relevant equipment to optimize and regulate the air quality through wireless gateway.

8. Wireless doorbell

This doorbell is very valuable for large families or villas. For safety reasons, most people will close the door when they sleep. At this time, when someone comes to press the doorbell, it is difficult to hear the bell in the room. This wireless doorbell can transmit the ringing signal to the bedside switch to remind you that someone is visiting. In addition, when there is no one at home, the action of ringing the doorbell will be transmitted to your mobile phone through the gateway, which is very important for you to understand the safety status of the family and visit information.

9. Wireless door magnet and window magnet

It is mainly used for intrusion prevention. When you are at home, the door and window magnets will automatically be in the disarm state without triggering the alarm. When you leave home, the door and window magnets will automatically enter the disarm state. Once someone opens the door or window, it will notify your mobile phone and send an alarm message. Compared with the traditional door and window magnet, the wireless door and window magnet can work without wiring, and it is very convenient to install. The installation process generally does not exceed 2 minutes. In addition, for families with safes, this sensor can also detect and record the time when the safes are opened or closed each time and notify the authorized mobile phone in time.

10. Solar wireless intelligent valve

This is a wireless irrigation system powered by solar energy. The general work flow is that the soil moisture sensor sends the soil water content to the wireless gateway. Once the soil is short of water, the wireless gateway will send a control command to the wireless intelligent valve to notify the water supply, at the same time, it will send the water supply time and water supply volume to the gateway, and save it on the mobile phone or other devices through the gateway.

11. Wireless bedside sleep button

This is a battery-powered device that can be fixed or pasted on the board at the head of the bed. Its main function is to help you turn off all electrical appliances that should be turned off while sleeping and start the security system to enter the deployment state. For example, start the wireless infrared intrusion detector, window magnet, door magnet, etc. to enter the early warning deployment state. In addition, it can also help you start the lighting mode at night. For example, when you get up at night, the light on will be very soft, but not as bright as when you eat, even if it is the same light.

12. Wireless gas leakage sensor

The sensor is mainly used to detect the gas leakage in the home. It does not need wiring. Once there is a gas leakage, it will send an alarm through the gateway and notify the authorized mobile phone.

13. Wireless radiation sensor, wireless air pollution sensor

For some people who are sensitive to solar radiation, this sensor has special significance. Through it, you can accurately know whether you need to take measures to prevent solar radiation or pollution and dust before going out. The only thing you need to do is look at the mobile phone screen, because outdoor radiation, pollution and other conditions have been transmitted to your mobile phone through the wireless gateway.
