Network high-definition cameras is mainly composed of video capture, video coding, network transmission, etc. Network high-definition cameras compared with analog cameras, in terms of definition, 700 line analog camera is extreme, but network high-definition cameras 5 million pixels have already come out, high flexibility, high performance network cameras. And network camera just relying on the network transmission, this is the biggest difference.

1, the difference between image pixels, simulation using CCD as the sensor, is limited by certain technical bottlenecks in the quality, general analog camera now is highest 700 TVL, in radio and television in the standard sd D1. Mainly use CMOS light-sensitive components and IP camera can do more than millions of pixels of image quality, gm is currently between 1 million and 2 million, there are also updated technology products in the market, 5 million, 8 million, estimates that there are millions of image quality of camera will soon put into market, it is understood that the United States of T1 company must pixel camera has completed testing, frame rate can reach 15 frames.

2, the analog camera is not in the management software for intelligent analysis and the custom, such as define its use function, because there is no IP to remote browse alone also bring inconvenience.

3, in the equipment control, such as PTZ, simulation of ball mill is also increase the line of control and codecs in the wiring to control the rotation of the ball mill and zoom, and IP camera is don't need, you can directly use the Internet line, also give wiring saves a lot of time and cost, especially in the larger project, network camera cost especially highlight the project quantity.
