With the deepening of the construction of safe cities, users' demands for high-definition and intelligentization are increasing. Combining the gradual maturity of IT technologies such as multimedia technology, codec technology, and network technology, high-definition surveillance has begun to move towards the practical application, and the high-definition IP camera has gradually become the leader of front-end video capture products in the security industry.
At present, there are mainly two types of IP cameras: SD and HD network cameras. However, the shortcomings of standard-definition network cameras are very prominent. The picture is blurred and the resolution is low. When there is an emergency and need to watch the video playback, it is difficult to distinguish the details of the scene of the incident and cannot provide effective information.
With the market's increasing demand for video surveillance image quality, the smart HD IP camera is developing rapidly. The demand for network high-definition products is even stronger. The entire industry's demand for high-definition products has become clear.
The image acquisition of high-definition network camera adopts large-size image sensor, digital video compression and network access module to convert digital video signal into data stream conforming to network transmission protocol (such as TCP/IP protocol), and send it to the network for transmission. It is featured flexible networking, easy implementation, low cost, and significant effects.
