Visual doorbell is usually divided into active doorbell and passive doorbell according to the power supply of doorbell transmitter; According to the installation mode of doorbell, it can be divided into wired doorbell and wireless doorbell; It is called visual intercom system and building visual intercom system.

Wireless visual intercom doorbell is a doorbell used for short distance communication based on analog signal transmission and digital signal transmission. There are many names of wireless visual intercom doorbell, which can be called: wireless visual doorbell; Wireless visual intercom doorbell; Wireless intercom doorbell; 2.4G wireless doorbell, etc.

It is also a wireless visual intercom doorbell. It is mainly divided into three aspects:

1. Division of doorbell installation methods

It is divided into wired doorbell and wireless doorbell. Wired doorbell is troublesome to install and requires wiring, generally engineering doorbell. The household visual doorbell is easy to install, and only the transmitter is needed. Fix it outdoors with double-sided sponge stickers or screws. The receiver can be used after installing batteries or plugging in the indoor power supply.

2. Power division of doorbell transmitter

It is divided into active doorbell and passive doorbell. The transmitter of the active doorbell needs a battery to provide power, with stable performance and beautiful appearance. The transmitter of the passive doorbell uses kinetic energy to convert into electric energy to provide power, never replacing the battery.

3. According to the coding and decoding method of doorbell

It is divided into fixed code doorbell and learning code doorbell. The receiver and transmitter of the fixed code doorbell use the same address coding. The address coding is easy to re code. If you want to add a receiver or transmitter to the factory standard configuration, it will be very troublesome.

Precautions for use of wireless visual intercom doorbell

1. At present, there is a small gasket under the battery of many wireless visual intercom doorbell transmitters. Some people may think that this gasket is useless, so they don't use it. In fact, this gasket is very important. Only when this gasket is placed under the battery can the transmitter be contacted normally, so the transmitter can be used normally. So don't throw it away as waste paper.

2. The wireless doorbell must not be installed near the TV, induction cooker, microwave oven and other electrical appliances with electromagnetic waves, and should be as far away as possible, otherwise the electromagnetic waves will interfere with the signal received by the doorbell.
