With the development of economy and the fact that there are more people in many cities in our country, community gregariousness is a realistic choice of national conditions. In this situation, there emerged a unit of non-visual video intercom, a networked non-visual intercom system, and a CRT. Black and white video intercom system, color TFT screen video intercom system, security video intercom system, semi-digital networked video intercom system and digital building video intercom system.
In the 21st century, computers and Internet technologies have been rapidly developed. People have ushered in the era of digital life, and the video intercom industry has also set off a wave of digitalization. The digital video intercom system is a digital product evolved from the original bus-based video intercom. Digital video intercom products use standard TCP/IP protocols for system transmission. The TCP/IP protocol is currently the most popular open standard in the world and has the tendency to replace the field bus. Its adoption can avoid the weaknesses of the individualized and incompatibility brought about by fieldbus technology, and the security signals, home appliance control signals and three-table acquisition signals, audio and video signals, etc. can all be transmitted through the network. Using an embedded hardware platform and an embedded operating system, video soft coding/soft decoding uses a standard video compression protocol H. 264, the soft encoding/soft decoding of audio adopts the standard audio compression protocol G. 729, to ensure the compatibility and interconnection of systems between different manufacturers. The system provides a standard API interface that can provide an integrated platform for external vendors.
The introduction of digital technology not only solves the problems of poor anti-jamming capability, limited transmission distance, and incompatibility of the system in traditional intercom systems. The product is highly scalable, and it plays a role in system capacity, stability and community management. The role can not be matched by traditional intercom products. And using digital technology, it can provide standardized protocols and open interfaces. It can more easily integrate with other manufacturers' products, interconnect with other systems, and facilitate product upgrades and maintenance. The problems that have plagued traditional intercom systems such as call conversations, photo messages, and image transmission have also been solved. The use of digital network transmission not only overcomes the drawbacks of analog transmission, but also provides users with more diversified and more user-friendly features, and brings more added value, such as digital intercom can achieve traditional intercom can not be achieved Appliances intelligent control, remote monitoring, multimedia entertainment, surfing the Internet, etc., can also achieve advertising services, shopping, online VOD video on demand and other value-added applications.
Compared with the traditional bus-based analog intercom, IP digital intercom has been highlighted as having the following characteristics: the transmission distance is not geographically limited, and the expansion and upgrade are extremely convenient; the transmitted audio and video, control and other signal effects are much better than the traditional bus. It can realize the integration of multiple functions such as home alarm, home appliance control, remote monitoring, and community service; it is easy to install and debug, shortens the project cycle, and saves project expenses.
The prospect of digital video intercom system TCP/IP network technology has the incomparable advantages of the bus technology. With the development of the Internet, TCP/IP technology has shown tremendous vitality. The TCP/IP protocol is currently the most popular open standard in the world and has the tendency to replace the field bus. Its adoption can avoid the weaknesses of the individualized and incompatibility brought about by fieldbus technology, and the security signals, home appliance control signals and three-table acquisition signals, audio and video signals, etc. can all be transmitted through the network.
Intelligent products have created a new era of global digital homes. But in fact, this system still stays in the stage of centralized control of household appliances. There is still a long way to go from the real smart home life and the energy saving and environmental protection of home life.
Can not be ignored is that there are structural problems in the development of digital video intercom systems: how to expand the influence of networked/intelligent products? How to provide property management or engineering companies with more value-added service opportunities? How to solve the network service operating expenses? These need to be further resolved.
