The rapid development of the Internet, on the one hand, has greatly promoted the continuous growth of the network economy, and on the other hand, it has also played an inexorable power source in terms of quality of life. Surveillance and security products are also moving forward, and gradually a new type of surveillance camera appears in front of people in a brand-new attitude. It is a network camera. Network cameras have become synonymous with high-definition, networked and intelligent video surveillance. Due to the rapid development of electronics and network technology, the application value and scope of application have been greatly enhanced. The expansion of security requirements and the requirements of user experience have also greatly stimulated the development of network cameras towards all-around development.

Common network cameras can be roughly divided into two categories: one is a hybrid network camera combined with video processing and network transmission modules; the second is a common pure digital network camera. The implementation mechanism of the hybrid network camera needs to go through two analog-to-digital conversions, and its highest image quality is D1; ??while the implementation mechanism of the digital network camera is from A / D analog signals to network signals directly, which greatly improves the conversion efficiency The picture quality is high, so although the pixels are high, the code stream occupied is not large, and its network applicability is better.
The trend of the times is constantly flowing forward. In the era of analog surveillance, issues such as sharpness, blurred images, snowflake effects, noise, and whitening of the image often occur. In the non-security field, there are digital cameras, computer cameras, and mobile phone cameras with millions or even tens of millions of pixels. Analog monitoring products can no longer meet user needs, so high-definition has become a great demand concept in the mall, making it more valuable. In the trend of high-definition, people continue to improve their monitoring needs and manifestations. Network cameras have begun to develop in a deeper direction of high-definition and intelligence, which will also become the development trend of future network cameras.
