The difference between network camera and analog camera

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. The network camera can transmit only by relying on the network, which is the biggest difference between the two.

1, the difference of quality pixels, simulation using CCD as a photosensitive element, in the picture 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 effect. The IP camera is mainly used CMOS photosensitive components, can achieve more than megapixel image quality, the current general is 1 million to 2 million mostly, there are newer technology products in the market, 5 million, 8 million, it is estimated that soon 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. The cost of network camera engineering is particularly prominent.
