Network Camera Market Status and Development Analysis

IP network camera market status The speed of development of network cameras is very fast. HD network cameras such as AXIS, Sony, Panasonic, Samsung and other manufacturers abroad have been widely used in many projects, such as airports, high-speed rail, and banks. and many more. With the increase of users' demand for network cameras, the domestic network camera market has developed very rapidly in recent years. At present, domestic network camera manufacturers are mostly concentrated in Shenzhen, Beijing, Shanghai, Hangzhou, Tianjin, Suzhou and other places, these areas occupy the majority of domestic well-known security vendors. At present, Dahua, Hikvision, the Yellow River, and Kodak have certain brand awareness of network cameras in China. Although there are still some gaps in the products of domestic manufacturers compared with international brands, the products of domestic brands will be further improved along with the development of technology, and will also be widely promoted and applied.

According to statistics, in 2008, the domestic network camera market accounted for about 4% of the Chinese camera market, reaching 520 million yuan. In 2009, the network camera market grew by about 100% year-on-year, and its market size was about 1 billion yuan. According to the sales data provided by a number of network camera manufacturers, as well as the purchase amount of network cameras of various project providers, and with reference to statistical analysis provided by some chip manufacturers, the ratio of camera project applications in 2010 is 88% of analog cameras, network cameras Accounted for 12%, the latter's market size is about 1.5 billion. From 2008 to 2010, the market share of network cameras has grown at an average rate of 70%. In the first half of 2011, the proportion of camera project applications has increased to approximately 23%. According to statistical data, it is expected that the market size of domestic network cameras in 2011 will exceed the 2 billion mark.

HD network camera application needs clear HD monitoring, not a single security product, but a complete solution. In fact, with the rapid advancement of monitoring technology in recent years, technology is no longer a challenge for high-definition. At present, there are many monitoring front-end, transmission, and storage manufacturers that have outstanding research and development capabilities in China. Relatively speaking, it is somewhat tricky to have fewer professional total solution providers. This year, the surveillance industry popularizes and promotes the overall solution, the core of which is to promote high-definition solutions in various application fields, such as intelligent transportation or safe city. Leading companies such as Hikvision and Daewoo have expanded their product lines and increased R&D and investment in solutions. First-line surveillance vendors have also made almost all of their efforts in high-definition solutions, and are striving to have a place in the high-definition market.

Network cameras have standard definition network cameras and high-definition network cameras. Most standard definition network cameras have added IP modules to traditional analog cameras, mainly to meet those who do not have high image quality requirements, but they can achieve remote centralized monitoring. At the same time can also facilitate the construction and installation. In the current situation of relatively high prices of high-definition products, the market demand for SDTV network cameras still occupies a considerable share of the market, such as places based on computer local area networks for area monitoring, such as residential communities, office buildings, storefronts, shopping malls, and chain stores. The monitoring is mainly based on standard network cameras; some of them are used for cross-regional remote monitoring and also use SD network cameras, such as: general remote children and the elderly care, unattended room monitoring, Internet cafes monitoring and so on.

The application of high-definition network camera technology has gradually deepened to the era of high-definition surveillance, but the front-end must be an HD network camera. The reasons are mainly in two aspects: First, high-definition monitoring must be networked, and it must be based on video compression processing and transmission over an IP network, because only this can control the transmission costs of high-definition video. Uncompressed high-definition video signals after the acquisition have both analog and digital transmission methods. Analog transmission generally uses YPbPr component transmission, and one HD video signal needs three coaxial cables to transmit at the same time. Digital transmission generally uses DVI, HDMI, or HD-SDI transmission. The transmission distance of DVI or HDMI is only a few meters, which is not suitable for monitoring and transmission. Although HD-SDI can transmit about 100 meters, it has high requirements for coaxial cables. Cable prices are also very expensive. Whether it is analog or digital transmission, the transmission cost of uncompressed high-definition video signals is significantly higher than that of analog SD video signals. With video compression coding and transmission over IP networks, the difference in transmission costs between high-definition video and standard-definition video is small. Second, the efficiency and cost of directly using high-definition network cameras for front-end processing are better than using high-definition video encoders for high-definition cameras.

The current high-definition video sensor is mainly CMOS. The CMOS sensor directly outputs the digital video signal. In the camera, the digital high-definition video signal is directly compressed and encoded by the DSP or ASIC, and then transmitted in a networked manner, and the HD signal is output directly from the camera. It is economical and more efficient.

Today, the most prosperous is the concept and application of high-definition surveillance, and the success of many large-scale projects also shows that high-definition surveillance has gradually become mainstream. The development of high-definition IP cameras can be described as great progress. In addition to the current megapixels, 1.3 million pixels, and 2 million pixels, 3 million pixels, 5 million pixels, and 8 million pixels have appeared in the market. And more than 10 million pixels of products have begun to show their clues in the monitoring industry. In the investigation of the HD network camera of this publication, we have found that since 2009, with the high demand for high-definition monitoring in some industries such as finance and transportation and Ping An city, together with the Shanghai World Expo, Guangzhou Asian Games, Shenzhen Universiade and other large-scale activities to promote high-definition Under the monitoring trend, high-definition network cameras (resolution ≥ 720P) have mushroomed rapidly. Some mainstream network video surveillance vendors such as Panasonic, Sony, Hikvision, Kodak, Axis, Dahua, and the Yellow River have all launched megapixel network cameras to compete in the field of high-definition network surveillance. According to the survey, the total number of domestic HD network cameras shipped in 2010 exceeded 200,000 units, an increase of over 200% compared to 2009, accounting for approximately 34% of all network cameras. In HD network cameras, megapixels account for 56%, 2 million pixels account for 37%, and 3 million pixels or more account for 7%.

Conclusion With the continuous improvement and development of monitoring technology, IP cameras as one of the main directions for the development of monitoring technology will surely usher in the spring of development.
