The difference between IP network HD camera and analog camera

The difference between IP network cameras and analog cameras is mainly reflected in four aspects:

1, the difference between quality pixels, analog cameras use the CCD as a photosensitive element, in the image quality by a certain technical bottlenecks, the general analog camera is now up to 700TVL, also in the standard of radio and television to achieve standard definition D1. The IP network cameras mainly use CMOS sensitized components and can achieve image quality of over megapixels. At present, GM is generally 1 million to 2 million, and there are also newer technology products in the market, 5 million and 8 million. There are tens of millions of quality cameras will be put into the market, it is understood that the United States T1's 10 million pixel camera has been tested, the frame rate of up to 15 frames.

2. The analog camera cannot give intelligent analysis and customization in the management software, such as defining its use function, because no IP also brings inconvenience to remote browsing alone.

3, in the equipment control, such as PTZ, the simulation ball machine is in the wiring additional control line and codec to control the rotation and zoom of the ball machine, while the IP camera is not necessary, you can directly use the network cable, also to Wiring saves a lot of man-hours and costs, especially in relatively large projects, especially the cost of IP camera engineering.

4. Although SDI has high picture quality and there is no delay, its compatibility is currently limited, so it is rarely used in China. At present, the domestic and foreign camera brands are mostly IP, so SDI has not become mainstream. SDI cabling is basically the same as analog cameras, increasing the cost of construction and use of the line, and the faults in the future are all found to be inferior.

Network HD cameras are mainly composed of video capture, video encoding, and network transmission. Compared with analog cameras, network HD cameras have 700-line analog cameras that are the ultimate high definition, but 5 million pixels of network HD cameras have emerged. The network cameras have high flexibility and excellent performance.

“HD network cameras and SDI cameras have their own application areas and focuses. They are complementary rather than replacing relationships. In terms of video quality, both SDI cameras and HD network cameras can reach the 720P/1080P level. Even SDI cameras can provide higher levels. With the transmission frame rate, SDI cameras have higher definition images, higher resolution, and richer colors, which can meet the high-definition monitoring requirements of users, but the transmission distance of SDI cameras in video transmission is very limited. It can transmit about 100 meters, and the network camera can transmit only by relying on the network, which is the biggest difference between the two.
