preface

As people's safety awareness is getting higher and higher, the doors at home are more and more thick, but the thicker the door, the better the sound insulation ability. Another problem caused by this is that it is easy to not hear your family and friends calling at the door. So you need a wireless doorbell at this time. Not long ago, LinkedIn Technology released a self generating doorbell -- Linbell G4. The appearance and the sense of technology are full. Let's take a closer look.

Unpacking

Linbell G4 is mainly packaged with environment-friendly kraft paper. There is a rough drawing of the product on the front of the package, and there is the brand logo of LinkedIn Technology on the left.

On the back of the Linbell G4 package is the detailed information of the product and some information of LinkedIn Technology, as well as the QR code of LinkedIn Technology's WeChat official account. You can scan the official account to learn more about LinkedIn Technology's new products and information. There are some special functional graphic signs of the product under the package.

List of Linbell G4 main accessories, transmitting end * 1, receiving end 1, 3M rubber block * 1, instruction manual * 1, self tapping screw * 2, rubber particle * 2.

Product details

Linbell G4 transmitter adopts white as the main tone, and the display is very clean and concise. There is only one Linbell product logo in the upper middle. There is also a shallow dent at the lower middle part. Mark the pressing position. The biggest black technology is this transmitter, which does not need batteries and can generate electricity by pressing. Every time you press the doorbell button, the energy can be converted into electric energy and send wireless signals.

There are two buckles on the back of the transmitter for easy disassembly and assembly, and there is a screw hole in the middle for installing screws.

The receiving end of Linbell G4 also uses white as the main tone. Like the transmitting end, Linbell's product logo is printed on the middle and upper part. The lower middle part is an integrated blue transparent button with lights, the left side is the volume key, and the right side is the music selection key. When someone presses the doorbell, the integrated button will give a blue light prompt.

From the back of the receiver, we can see that a fixed two tooth plug is used for power supply. The two tooth plug is more versatile and convenient to plug into different environments than the three tooth plug. Below is the speaker opening. Although the opening position is small, the volume is very loud and clear.

The instruction manual is not only the instruction manual but also the warranty card. From the instruction manual, we can see the very detailed installation method. There are two installation methods. One is to use 3M adhesive tape to stick it on the wall, which is very convenient, but we are afraid that the malicious person will tear the transmitter away violently. The other is to fix holes on the wall with self tapping screws and rubber particles, which is a little troublesome, but this method is the safest and most stable. In addition to the installation method, we can also learn from the instructions that the receiver can pair multiple transmitters and set different ringtones for different transmitters. It is used to distinguish front and rear doors. Very humanistic.

Installation and use

According to the instructions, just stick one side of the 3M adhesive tape to the transmitter and the other side to the wall.

The other method is to make holes on the wall, remove the rear panel, and then fix it on the wall with self tapping screws.

summary

After many days of use by myself and my family, I think Linbell G4 is very good. The receiver of a 120 square meter three floor room is on the second floor, and the sound of doorbell can still be heard on the first and third floors. Although the sound is a little small, it is still much better than people shouting at the door. Also, it is much better than the one that used to use batteries. First, the appearance of the Linbell G4 is fashionable and beautiful, which is really beautiful compared with the big and ugly one before. And it is self powered. It is not as boring as the old one that needs to change batteries from time to time. However, if the door is closed in the room, the sound of the doorbell will be very low. It would be perfect if the power of the doorbell could be increased.
