Analysis of prospects for the development of HD IP Camera

To the era of high-definition monitor, front-end must be HD IP Camera. The reason is mainly in two aspects:
First, the high-definition monitor must be networked, must be based video compression and transmission over an IP network, because the only way to control the cost of high-definition video transmission.
Uncompressed high-definition video signal acquisition both analog and digital transmission. Analog transmission YPbPr component transfer three coaxial cable, all the way high-definition video signals need to be transmitted simultaneously. Digital transmission of DVI, HDMI or HD-SDI transmission of DVI or HDMI transmission distance of only a few meters, and is not suitable for monitoring the transmission, and HD-SDI can transmit about 100 meters, but demanding coaxial cable , the price of cable is also very expensive. Whether it is analog or digital transmission of uncompressed high-definition video signal transmission costs are significantly higher than the previous analog standard-definition video signals. The use of video compression coding and transmission over an IP network, HD video and SD video on the transmission cost difference is very small.
Second, the direct use of HD IP Camera front-end processing efficiency and cost more advantages than high-definition video encoder HD cameras.
HD video sensor CMOS-based digitized video signal directly to the output of the CMOS sensor in the camera through the DSP or ASIC digital high-definition video signal compression encoding, and then transmitted to the network than the camera directly to the output HD signals more economical and efficient processing.
HD network camera technology applications gradually deepening
Today, the most prosperous, the concept and application of high-definition monitor, and many large-scale projects success also shows that high-definition monitor has gradually become the mainstream. The development of high-definition IP Camera can be described by leaps and bounds, more contact megapixels, 1.3 million pixels, 2-megapixel, 3 megapixel, 5 megapixel has appeared on the market, or even 10 million and more than 10 million pixels products have begun to emerge in the surveillance industry. Since 2009, with the financial, transportation and other industries and safe city part of the project, the high demand for high-definition monitor, coupled with the Shanghai World Expo and Guangzhou Asian Games and Shenzhen Universiade and other large-scale activities to promote high-definition monitor trends, HD IP Camera (resolution greater than equal to 720P) mushroomed to grow rapidly. Like the well-known HD IP Camera manufacturers - Shenzhen Wei, as the dot-com Technology Co., Ltd., the first to introduce megapixels network camera, acclaimed in the high-definition network surveillance. The survey shows that the 2010 domestic HD IP Camera shipped throughout the year total more than 20 million units, compared with 2009 growth of more than 200%, accounted for approximately 34% of the network camera. HD network camera megapixels 56%, 37% from 200 million pixels, 3,000,000 pixels or more than 7%.

With the continuous improvement and development of monitoring technology, one of the main direction of development of the IP camera monitoring technology, combined with optical imaging technology, intelligent analysis technology, network transmission technology, and so bring new changes continue to meet the needs of market competition tend to be a self-perfect realization. It has a profound impact on the field of monitoring technology will also profoundly changed the way we live. Especially in the current network environment, escalating the increasingly widespread application of the Internet of Things, network camera will eventually usher in its dawn.
