Application of “One Machine Connected” Community Building Visual Intercom System

With the improvement of people’s living standards, people’s requirements for smart communities have also increased. From the perspective of urban and residential environment planning, in order to provide residents with an open and natural space and create an overall “safe, convenient and civilized” community, it is necessary to establish an effective digital video intercom system for buildings. ; At present, the competition in the real estate market is increasingly fierce. How to increase the added value of the house and increase the selling point of the house is also the focus of real estate developers. At the same time, it plays an important role in improving the level of property management and maintaining social stability.
1. Disadvantages of the previous system:
In the past, the building intercom system could not reliably form a network for a large residential area with more than 4 residential gates and 50 staircase doors. Because the door operator of each elevator door is a “negative host”, and a networked host is used to connect the “negative hosts” of 50 elevator doors, the video sent to the residents can only be the video of a single elevator door. . Therefore, the “building intercom” can only be a simple intercom and door opening upstairs and downstairs, and the video can only see the image downstairs.
As for a large-scale community, its various gates must be difficult to reach the households with the traditional intercom system video. There is only one communication point from the computer room to the household. A pair of 50 ladder doors “negative host”, and then for hundreds of household units. Imagine if the visitor can find the resident through the “building intercom” from the gate of each community smoothly? In the case of communication failure, community security may be helpless, resulting in many unnecessary disputes with visitors.
In many communities, due to technical problems, the security guards standing at the gate of the community never cared about those who entered the community, or only stopped some disheveled and “suspicious” people. In the end, they became a “mighty door god”. The final result is to invisibly reduce the “level” of the cell.
Let’s look at the hotel again, why the lobby attendant can easily contact the guest in the room, and it is so easy for the guest to find any department of the hotel, this is because the hotel uses an internal telephone system (there will be no cost).
In addition, the structure of the bus of the traditional building intercom system determines its unreliability: any short-circuit fault in one household will lead to the paralysis of the entire system. The “traditional building intercom system” with independent power supply is adopted. When the user’s home is powered off, the function is completely lost, which is even more unacceptable. In addition, each unit has to forcibly install a non-universal “opening phone”, which makes the residents hate it, because no matter how good the decoration is, it cannot be avoided.
I believe that every developer wants to create a safe, peaceful and orderly community environment for his residents. Because it is related to the reputation of the developer and property management, it is a strategic plan for survival and development.
2. “One machine connected” community building intercom system:
Because this system of NetEase adopts the technology of the program-controlled telephone exchange as the host, each elevator entrance is no longer the “host” in the past, but an extension in the same program-controlled telephone exchange as the household. Even if the community has 10 gates and 100 to 200 staircase doors, networking is not a problem, and the entire community can be connected. To what extent, this can be stipulated by simple programming at the end of the property management. Easy to change at any time.
Multi-purpose machine
A household only needs a standard ordinary telephone at home to make and receive a completely independent external line for each household, without changing the existing usage habits, and can use the phone to call any service point in the area at any time (in the past, the most Only call security), or open the door for visitors. The standard telephone used here can be a cordless telephone purchased by the resident, or an ordinary telephone whose color, keyboard, style, etc. all meet the requirements of the resident.
Multiple video channels can be used at the same time (visual user)
Because the advanced video modulation technology is adopted, after the video signal reaches the household terminal, the whole system will not be paralyzed due to a short circuit in one household. The biggest advantage is that it can transmit multiple videos at the same time. For example, while the resident A looks at the picture of the east gate and talks to his visitor, the resident B looks at the south gate and talks to his visitor.
The resident does not need to press the TV, as long as he answers the door call from the camera equipment, the TV will automatically turn on and jump to the corresponding video pre-selection. This TV is an ordinary TV and can also play ordinary TV programs.
Residents can instantly print a “letter slip” for visitors at the gate of the community through the phone keypad, and can also open the door for visitors downstairs. Residents themselves can open the door through the resident’s contactless IC card. After the resident answers the call, confirm the identity of the visitor, and perform simple operations through the telephone: press a “#”, and immediately print out a “Room Number” and date and time at the visitor’s end. “. Security guards can carry out security work in the community according to the resident card and valid “release slip”. Convenient and well-founded.
The visitor enters the community and goes downstairs of the building, dials the resident’s telephone through the building’s wall-mounted telephone door operator, and the resident answers the call, and also presses a “#” to immediately open the door of the resident’s downstairs stairwell.
High reliability
Due to the use of telephone program-controlled switch technology, its reliability is unparalleled, and the entire system will never be paralyzed due to a short circuit caused by decoration or improper use of one household. There is also no need to provide power at the home, which avoids the communication blockage or the failure of zone monitoring due to a power failure in the home of the “separately powered system”.
