Building visual intercom system is a kind of equipment used for high-rise residence, inside and outside of apartment building, information transmission between households, anti-theft door control and residents' alarm to the building duty room in case of emergency.Do you know the common building intercom transmission methods? Let's have a look today!

1. Apartment

The number of intercom extensions in the apartment is small and the transmission distance is relatively close, which is generally transmitted within 100m. According to the service characteristics of the apartment, the tbc-4FP4110N building dedicated switch of Tianbo is recommended for the transmission equipment, and there are 8 spoe ports that can provide power supply and data transmission to the extension through CAT5 and above network cables; The uplink port can be directly connected to the host.

2、low-rise buildings 

For low-rise buildings , if there are 2-4 households on the first floor, we can choose the transmission equipment. On the first / second floor, we can use a TBC-4FP4105N building dedicated switch to provide power supply and transmit data to the building extension. All TBC-4FP4105N uplink network ports return to the floor convergence switch through the network cable. The tbc-s5008e switch of Tianbo is recommended for the floor convergence switch, Finally, the floor convergence switch is directly connected to the host.

3、High rise building

Because the floors of high-rise buildings are high, if each building dedicated switch pulls a network cable down, it needs to pull many lines down. The wire cost increases the cost. Needless to say, so many cables also affect the appearance and are inconvenient for later maintenance. At this time, you can choose the cascade method. Take the tbc-4fp4110n building dedicated switch of Tianbo as an example. The application topology is as follows.

4. Smart community

The buildings in the smart community are relatively concentrated, but there are many buildings. At this time, in addition to the transmission of each building, the building data of each building needs to be transmitted to the central computer for management; Each aggregation switch transmits all data to the management switch in the central machine room for management through optical fiber transceiver. Tbc-s5308ge-24gf4tf of Tianbo is recommended for the management switch. The application topology is as follows.

The topology diagram is for reference only, and the actual application needs to be designed according to the site.
