The diversified development of the 3G wireless video surveillance operating model

3G wireless video surveillance is a key application direction in the Internet of Things era: video cameras and other sensor devices form the perception layer of the Internet of Things, collect basic data of the Internet of Things, and then transfer it to the video application platform through the transmission of the network layer. Other application scenarios (including personal applications, industrial applications, public domain applications, etc.) process, identify, and apply corresponding data, and perform automatic and even intelligent processing of related transactions and control of related objects. The telecom operators' IoT strategy will help 3G wireless video surveillance to achieve diverse applications and application levels. The national Internet of Things strategic plan has the following significant functions for advancing 3G wireless video surveillance:

· Better understand the needs of various industries, and quickly achieve infiltration coverage of various industries;

Breakthrough the market of small businesses and individual users;

· Strengthen the comprehensive application of video surveillance and other technologies to speed up the upgrade.

3G wireless video surveillance, as another key area for China's IoT industry, has ushered in an explosion of growth. With the completion of the domestic 3G network construction, video surveillance based on 3G networks has become a new hot spot in the domestic video surveillance industry. Due to the advantages of flexible deployment and low overall cost, the application of 3G wireless video surveillance gradually breaks through traditional video surveillance, and Electricity, etc. continues to expand into education, public utilities, small and medium-sized enterprises, and household and personal markets.

Segment market development With the successive launch of 3G networks, operators began to consider how to put into use. Because the network itself is only a channel, only the business can be profitable, but since the commercial use of 3G, market development has always been an important issue that plagues operators.

Dong Baoqing, deputy director of the Department of Informatization Promotion of the Ministry of Industry and Information Technology, once said that if 3G wants to succeed, the most important thing in the current phase is vigorously advancing applications based on 3G. He believes that advancing 3G applications is no longer a technology-driven issue, but requires two-way technology and business drivers to produce new business models. Without market application, it is impossible to recover investment. If a good technology does not have a good business model, the market will die. 3G should not be confined to the personal consumption market. Its industry application is not a large-scale replication. Instead, specific business models should be created in each segmented market. Therefore, the segmentation market is both a new blue ocean for the future development of communications operators and it will also be A long-term market with considerable earnings.

Advantage Analysis 3G wireless video surveillance has a wide range of applications in the following scenarios:

· Places where wired networks cannot be reached or where the price of wired networks is too expensive: power lines, highways, environmental monitoring, forest fire prevention, street lamps, oil exploration, oil pipelines, logistics, transport vessels, flood prevention, and so on;

· Places inaccessible to personnel: such as inflammable and explosive areas, disease-infected areas, and other microbial hazardous areas;

· Relatively unstable sites to be monitored, temporary wiring will be a waste of cost: public security investigation of temporary deployment, military field training, temporary construction sites, temporary activity venues, convention centers and so on.

The advantages of 3G wireless video surveillance are mainly reflected in the following aspects:

· Wide coverage: The wireless network coverage of mobile phones is extremely high, and it is hardly restricted by complex terrain and areas such as mountains, rivers and bridges;

Easy deployment: Wireless video surveillance systems can be deployed virtually anywhere in the outdoors, including water, rugged terrain, and remote locations. Front-end encoders or network cameras, and even mobile phones, adopt wireless access methods. They only need to be covered under the mobile network, and they can easily and conveniently set up monitoring points, eliminating the cumbersome and cumbersome cabling caused by complex terrain.

High data throughput: Considering the development of future WIFI and 3G technologies, wireless network transmission bandwidth can be as high as 6Mbps to 200Mbps.

High reliability: The reliability of high-end wireless transmission systems is as high as 99.999% carrier-grade reliability, enabling uninterrupted secure transmission.

· Low cost: Exemption from the high cost of long-distance network cabling;

Easy to monitor: You can use your mobile phone for wireless video monitoring anytime, anywhere, not limited to a computer pre-installed with a monitoring client;

Business diversity: Wireless video surveillance can not only cover all fixed network monitoring services, but also can carry out various mobile services, such as: mobile law enforcement monitoring, mobile interviewing and other services.

The difficulties faced are similar to those of 2.5G. Although 3G has already begun to be applied to wireless video surveillance, there are still some problems in the transmission of huge video streams.

The bandwidth and frequency resources of wireless networks are more limited, and the bandwidth that can be achieved is far lower than that of wired networks: Since the effective bandwidth of a single terminal of a public mobile communication network is quite limited, it is often necessary to carry voice, data, and other transmission services at the same time. Even if the current 3G network is used to transmit CIF images, a base station cannot exceed 3 monitoring points, and wireless broadband is characterized by the uncertainty of the transmission bandwidth. Currently, 3G networks can reach 1M at high speed, and only a few dozen at slow speeds. K, so it can only be used as an auxiliary transmission method;

· The error rate of the wireless channel is relatively high: especially when the terminal device is in a moving state, the available bandwidth and bit error rate index have a significant decrease, the available bandwidth fluctuates frequently, and the high bandwidth video monitoring data is prone to packet loss. Reliability is not high;

Wireless transmission charges are also much higher than wired transmissions: In general, wired transmission is more cost-effective than wireless transmission, and broadband transmission is even more so. The operating costs of the 3G wireless video surveillance system include broadband Internet access fees for video sources, mobile viewing fees, monitoring system operating costs, etc. The total operating costs are high, and it is difficult to decline.

• When a public communication system sharing channel resources experiences a dramatic increase in local loads in an emergency situation, it may cause intolerable delays or even blocking problems.

Single application of business applications to expand business may be a problem that every emerging market must face, and it must also be addressed. The abundance of business functions is a powerful tool for promoting the development of 3G wireless video surveillance. Japan and Hong Kong are regions where 3G was introduced earlier. They have rich and innovative applications for 3G networks, such as: high-definition video, traffic monitoring, and real-time navigation. Online shopping, online games, mobile wallets, online video playback, live TV broadcasts, etc. Through the enrichment of business functions, the selection space for mobile phone users has been expanded, and users' interest in 3G services has also been indirectly attracted to the development of potential demand.

Relative to the more mature areas of 3G services, the domestic 3G wireless video surveillance service function is still very thin. Although in the 3G wireless video surveillance, mobile terminals are no longer just browsing tools, but can carry out more control and platform operations. However, as far as the current situation is concerned, video browsing is still the most used function due to reasons such as insufficient processing capacity and system maturity.

In the past two years, more technologies and functions will be applied and embodied in 3G wireless video surveillance products, including voice transmission, video capture, mobile information processing, multi-system integration, and richer intelligent control functions, etc. The application is far greater than the current imagination, and it is far more vital than simply monitoring video playback. As business becomes more mature, how to continue to innovate will be a decisive factor in how fast the market can grow. It is very important for the business operators to push the market. 3G wireless video surveillance is a new topic, and operators need more operational mechanisms to protect them.

3G wireless video surveillance can win its mobility and network coverage. Its main application areas should include several aspects:

· Specific industry user business: areas such as security management, road management for traffic, urban management, ambulance, etc. that require mobile video surveillance are mainly requirements for wireless video capture and mobile video viewing. Technically speaking, only 3G wireless transmission can meet the above high requirements. The in-depth integration of 3G wireless video surveillance with specific industries will become an inevitable trend in the development of the mobile video surveillance market;

· Home and business monitoring services: such as small and medium-sized shops networking, civil-level home security care and so on. Prior to this, the domestic home wireless video surveillance business had not yet reached the opportunity for a larger area. The difficulties were mainly in three areas: applicable wireless networks, cost issues and awareness issues. With the continuous improvement of the home network and mobile network environment, the increase in consumer spending and security awareness, and the increase in free-standing households, the domestic home monitoring market, which is generally only monitored for a short period of time, will begin to rise. When a thieves invade, accidental fire or gas leak, 3G wireless video surveillance system will send alarm information and images to the owner's mobile phone, allowing the owner to learn and handle it in a timely manner; it can also shoot real-time images at home The video screen is sent to the owner's mobile phone for later forensics. This is quite attractive for high-end families. This area is a typical long-tail market. The scale of individual market needs is small, but the overall market capacity is huge.

Special occasion monitoring business: such as forest fire prevention, oil field, field substation monitoring and other industries with special environments. In these areas, the region is wide and the users are sparse. The outdoor installation and maintenance costs of the wired lines are very high, so the 3G wireless video surveillance can exert its important application value.

· Security monitoring and control services for public transport: Satisfy the video surveillance needs of various vehicles in the process of moving, applicable to financial armored vehicles, public security police vehicles, urban management inspection vehicles, emergency rescue vehicles, freight vehicles, long-distance passenger cars, and taxis Vehicles and other types of vehicles, subways, railways or ships.

The operating model seeks multiple variables. It is understood that the current 3G wireless video surveillance is mainly based on the fixed network monitoring based on the mobile phone application overlay, users purchase their own or provided by the operator mobile phone terminal, through the installation of the corresponding plug-in to achieve video browsing and control . In general, the front-end equipment and central server are still responsible for procurement construction by the operator, and the operator provides services to the users after purchasing the platform from the platform vendor.

In terms of costs, the charging mechanism for 3G wireless video surveillance is not clear. According to the operator, due to the importance attached to the mobile video surveillance business, the cost will also be considered to give great discounts. According to different circumstances, it may adopt additional functional fees or monthly subscriptions. For example, operators may charge tens of dollars in functional fees, and the subsequent traffic charges will be calculated over time, and traffic charges will be relatively low. Compared with the previous fixed-line monitoring, the cost has not increased, but may be reduced.

Some people think that: At the present stage of the immature 3G network, this mode of operation draws on the advantages of fixed-line monitoring and is very familiar, and it is very good. The opposing voice believes that 3G has its own characteristics and advantages, and the operating model should be more innovative. , flexibility to achieve the full use of 3G advantages.

With the development trend of continuous and rapid growth of public mobile communications and the evolution of mobile communication networks to 3G, new broadband wireless access technologies such as WiFi, WiMAX, and WBMA and short-range wireless technologies have emerged one after another, and they are gradually maturing. The development of wireless communication industry A new pattern of diversification and complementary advantages. With the continuous development of communication technologies and the gradual evolution of networks, 3G and various broadband wireless access technologies and short-range wireless technologies are presenting a trend of convergence and development. This will become a broader space for future mobile surveillance applications.

With the maturity of 3G networks, the deepening of triple play, the implementation of M2M strategy, and the deployment of wireless cities, the future carrier-class video surveillance platform will adopt a unified media format and control signaling to support cloud platform deployment and virtual storage. Fully compatible with carrier-class operation network management. Video surveillance will serve as a sub-product package for carriers' unified services. With different business models, it will enter the government, corporate and other industry users and household personal user markets. 3G wireless video surveillance will become a convenient and convenient application that is increasingly known to the industry and the public.

But just like the development of network video surveillance in previous years, the development of 3G technology does not mean that the wireless video surveillance market will be widely used in one or two years. On the contrary, this initial year is precisely the painful period of the wireless surveillance market. Regardless of the maturity of technology applications, the improvement of networks (including the construction of a network based on a combination of fixed and wireless technologies), changes in consumer attitudes, and changes in business models, the entire market will take a while to mature. During this period of time, the market and technology orientation will complete the integration of chip and device manufacturers, monitoring equipment manufacturers, monitoring and application platform developers, distributors and system integrators, terminal customers, and operation and maintenance service providers. 3G wireless video surveillance solution providers will bind their respective security vendors, provide final solutions based on network construction, and continue to optimize existing products and enrich the entire product line; operators will also build and improve their networks. And the use of fierce competition: from the base station's erection, signal coverage and tariff services and other aspects to improve, in order to occupy more markets.

It is worth pointing out that 3G currently uses CDMA technology as the core technology, but its data transmission speed is far below the declared 2 Mbps in advertising, and its actual transmission speed is only about 0.4 Mbps, and it may be even when the network is busy. One-third of the speed is not reached. This situation is only enough to transmit high-quality audio, but it is difficult to transmit high-quality video. In addition, CDMA technology needs more complex equalization and modulation in order to combat multi-path interference, and it is very difficult to implement. In order to promote the development of 3G and the transmission of high-quality video on mobile, people have studied the advantages of OFDM technology in the CDMA system, thereby introducing a combination of CDMA and OFDM technologies, namely CDMA-OFDM technology. In this way, you can overcome the shortcomings of low CDMA actual transmission speed (0.4Mbps), and can adapt to high-speed (>10Mbps) wireless network video communication. Therefore, the combination of CDMA and OFDM transmission technology will greatly promote the development of mobile video surveillance systems, making it the most widely used. So, in the process of advancing from 3G to 4G,

It can be said that the maturity of a market is complex and subtle, but this trend will be beyond doubt. In the process of advancing from 3G to 4G, the spring of wireless video surveillance is still worth the wait.
