The requirements for intelligence, safety, and convenience in the community are getting higher and higher, and the visual building intercom system can solve these problems well. The visual building intercom system prevents the intrusion of outsiders, ensures the safety of the home, and plays a reliable preventive role. No matter day or night, you can clearly see outdoor visitors. At the same time, improve the management ability of the community property to the community, so as to enter and exit the card and go home safely.

The visual building intercom system is a smart device that integrates voice, video, and data exchange and collection functions. It is also an important integrated device export for the Internet of Things in the future. Through the networked device functions, it has all the functions of face recognition, intercom, indoor monitoring outdoor, indoor remote unlocking, night vision, etc.; residents can talk to visitors while seeing the visitor's image at the indoor station and press the unlock button to control the opening of the iron door to prevent strangers from entering the building, with high security. This is the most basic function of the building intercom system.

1. Computer room equipment

The server needs to analyze and process faces or big data, and integrate management platform applications.

Core switch, data exchange call to each building

The management machine manages all the equipment in each building, by answering the relevant video or audio signals of the door phone and indoor extension;

The card sender authorizes the issuance of IC cards for access control.

2. Front-end equipment

The door phone is mainly connected to each device through the visual building intercom door phone, and the upper is connected to the indoor extension and the lower is connected to the core equipment of the computer room. Like LEELEN’s product: 5-inch TFT Screen Video Door Phone Model 16.

The indoor station is the equipment used by the homeowner to communicate with the outside world. You can use the extension to talk to the downstairs entrance machine and the management machine in the computer room, and feedback information to the property management center in time if there is a problem. Like LEELEN’s product: 7-inch IP Color Video Intercom Indoor Station V32.

3. Intermediate connection equipment

Floor switches (access switches) are mainly used to connect extensions to aggregation switches, and the requirements are not very high 100M switches.

The aggregation switch is connected from the floor switch to the core switch. At least one gigabit port is required to connect to the core switch.

Optical fiber receivers are products that mainly connect switches and switches. The function is to convert electrical signals into optical signals for transmission, and allocate bandwidth according to data requirements. It consists of 100M and Gigabit fiber receivers. If the switch has an optical port, it can be solved with an optical module, which can replace the optical transceiver. The problem is that the cost of the optical module is higher than that of the optical transceiver. It is recommended using the optical module for transmission in important networks.

4. Wire

The network cable is divided into the super five-network cable and the six-network cable, which is decided according to the demand, and the mainstream is the six-network cable.

Optical cables are mainly used for long-distance transmission cables. Construction optical cables with network cables exceeding 100 meters transmit signals without attenuation. This is the advantage of optical fibers.

The protective tube mainly protects the network cable or other materials, and protects the cable with a sleeve. The materials include PVC tube, JDG tube and other material protective tubes.

5. Networking mode

The core switch connects all devices with a network, and realizes the data exchange of each network device through the core switch, so that network devices and devices can access each other and realize the function of interconnection and mutual access. The visual building intercom server realizes the data management of the management platform and achieves the function of controlling the equipment.
