Features and advantages of visual intercom system based on network technology

· Fast transmission speed: The transmission speed of the local area network can currently reach 100 megabits to the desktop. If you use fiber to the desktop, you can also reach gigabit bandwidth, which is not possible with the bus system technology;

Digitization: The application of TCP / IP networking technology in the smart community is a revolution of the entire smart community technology, and it will carry out digital technology processing of sound, data and images. Therefore, the equipment in the entire community is a digital product;

· Simple transmission lines and convenient networking: Since sound, data and images are all digital signals, only one cell local area network is needed for the entire cell's networking line, realizing real cell networking;

· With online inspection function. Because the system uses the standard TCP / IP communication protocol, each device on the network has a fixed IP address, and its powerful data processing ability can detect the online status of online devices in real time;

· Realize the multi-channel function of the community. After the community adopts TCP / IP networking, its powerful data processing capability and hundreds of megabits of bandwidth make the realization of multi-channel in the community very simple. Even if there are multiple door hosts at the same time, there will be no channel congestion or busy lines. ;

· Low wiring cost. Since one network cable can solve the problem of system networking, in addition to this platform, it can also share the same line with networked closed-circuit monitoring, peripheral prevention, networked parking lot and other systems without rewiring. The cost of a traditional analog bus is much lower;

· With online patrol function. Using the non-contact card access control system of the door host, it can realize the online patrol function, that is, the card reader of the door host can be used as a patrol point, and real-time online patrol can be realized.

Based on the above technical characteristics, the smart home developed on the basis of it has powerful functions:

· Network video intercom function: each resident in the apartment can see the visitor picture through their terminal screen, talk with them, and control the unlocking;

· Internal telephone function: That is, any two indoor terminals in this system can talk to each other, and the terminal can actively call the extension, just like the internal telephone, it does not incur any telephone charges, and can also contact the security management center;

· Powerful security function: The security management center can receive calls and alarm signals from residents in the community. The security management center is equipped with corresponding software. When there is an alarm event, the software automatically jumps out of the alarm prompt interface and displays the alarm type and resident number. You can also browse various historical records such as alarms, calls, access control, etc. The resident's mobile phone can also receive alarm information, etc. The user can control and operate through the phone and Internet network, and the function is very powerful;

· Store visitor's photo function: when a visitor visits the resident, the system can automatically store the visitor's photo. In addition to viewing the image on the terminal, the resident can also use the Internet, mobile phone WAP, etc. to browse the visitor's image;

· Remote monitoring function. Due to the use of network cameras, users can see the situation in the community through the terminal at home, and can see what happens at home through the Internet network when going out (enter with a password);

· Powerful information service function. In addition to receiving cell announcements and basic information, the user terminal uses the form of Ethernet, and the home gateway becomes the control core and protocol conversion center of each home. Using the home gateway can easily form and expand the cell network arbitrarily. Through the cell network information platform, Realize various fast and convenient value-added services in smart communities;

· Home appliances intelligent control function: Due to the use of wireless / infrared forwarding technology, home appliances can be operated and controlled through the home smart terminal color touch screen, and can also be remotely controlled by dialing calls and Internet networks;

· Light control: The terminal of the smart home system can centrally adjust the brightness of each room, switch control, scene combination control, etc. The control path can also be controlled by terminals, WEBPAD, Ethernet, mobile WAP, telephone, etc.

· Electric curtain and shading system control: After docking the curtain motor controller and shading system with the home gateway, the curtain can be automatically controlled at the user terminal, and each curtain can be controlled individually or in groups in each room And control according to the setting scenario. The shading system is equipped with an automatic rain sensor, which can be automatically operated when it rains. The control path can also be controlled remotely by terminal, WEB PDA, Ethernet, mobile WAP, telephone, etc .;

· The video intercom and home intelligent control system are ready for connecting to the Internet of Things system in the future, making it possible to connect to the Internet of Things.

At present, the appearance of the video intercom and home smart system are closely related to the latest trends of consumer electronics, and are close to the appearance of the most popular and popular electronic products in the world, such as the indoor unit imitating IPAD, IPHONE, netbook, etc. They are all ARM series single-chip microcomputers, such as ARM11, ARM9 and so on. High-end machines have CPUs that use netbooks, and the appearance is closer to a tablet computer. The system uses all-digital full set of equipment, and is basically developed based on the development model of miniaturized computers. It is in line with the current development direction of informatization and digitalization, and it also indicates that the security industry will come to an era when digital devices will completely replace analog devices in the near future. In software design, the technology completely adopts the current idea of computer windows, giving users a simple and easy-to-learn feeling of operating computer equipment, without losing the humanity and modern technology style. It breaks through the traditional ideas of the past, that is, the interface is simple and the function is single, the operation is complicated, and the consideration of actual use is missing. At present, almost all the latest products are based on TCP / IP technology.

For the software interface of the touch method adopted by most manufacturers integrating the home control system, and at the same time, for the situation where the user is mostly the elderly and children, the visual, humanized, fool menu is adopted for easy operation. Many manufacturers have also designed mobile phone-like home control phones based on WiFi. The various control panels are also very exquisite. Most of them use color LCD panels. Even at night, you can clearly see the color display of various electrical interface panels. Home control and access via the Internet has become a basic function. Because of the use of IP technology, the local area network of the community can be used during construction. The structure is imitated by IPAD, IPHONE and other streamlined appearances, ultra-thin, ultra-light, and compact, so most of them are wall-mounted. It solves the construction problems such as the need to pre-embed the wall in the past, which is more convenient and construction.

Therefore, the most representative products of the above characteristics are also the highest technical level of the intercom / smart home system development so far.
