At present, every high-grade residential area will basically install the product of building walkie-talkie, which can provide convenience for the daily life of residents in the residential area, but many people only know how to use the walkie-talkie and don't know how to wire it. Next, Bian Xiao will take you to understand this situation.

Connection mode

1. Crimp the signal line with screws.

At present, many installation workers will not use this connection method. Although this connection method is reliable, there are many connectors, which will bring a lot of trouble to the installation, debugging and later maintenance of the system.

2. Air docking

Basically, installation workers will use this wiring method, because the installation is relatively convenient and the process is not particularly complicated. Moreover, even if new equipment is replaced in the later stage, the old equipment will be dismantled faster and easy to maintain. However, this connection method also has defects. Because the connector is exposed to the air, it can not be used in humid areas, nor can it be used in places with too high temperature, which may easily lead to too high temperature of wires.

Transmission mode of walkie-talkie

1, ground state transmission

Now many communities will use this transmission mode, which can reduce the production cost of equipment. However, this transmission mode also has shortcomings, that is, the signal transmission distance of this product is relatively short, which is not suitable for high-rise residential areas.

2. Signal transmission

Modulation of video into signal transmission is widely used in TV, because the equipment cost of this transmission mode is relatively high, so it will not be used when installing building walkie-talkies in most ordinary communities.

3.s2485 transmission

This transmission method uses fewer wires, but the transmission distance is only 1.2 km, which is still relatively small for most communities at present. When using this transmission mode, the total number of access devices cannot exceed 50. If it exceeds 50, it will exceed the load, and then the equipment will be damaged. This transmission mode is generally used for the entrance guard of the community gate. Bian Xiao concluded: When installing walkie-talkies, it is best to find a professional installation master to install them. If people who don't know much about this are prone to wiring errors, it will not only damage the walkie-talkie, but also easily lead to electric shock and fire. The consequences will be more serious.
