Network camera and analog cameras What is the difference ?

Network camera and analog cameras What is the difference ?
Analog cameras and IP camera are today's mainstream products are used in various industries , so we use them in what they know about what is the difference between the two is it ?
Network camera ( digital camera ) is simply directly to the camera itself and the internal circuit by the CCD image captured into the digital signal via a network cable , the switch directly transmitted to remote monitoring easily . Simple analog camera image is converted into an analog signal , is transmitted through a coaxial cable, generally used for closed-circuit monitor . The difference between analog cameras and Network camera as follows:
1 , clarity
Network Camera : Progressive scan (up to millions or even tens of millions of pixels ) , more suitable for capturing moving targets , even moving at high speed can also provide a clear picture of the image .
Analog cameras : interlaced ( resolution 4CIF, can only reach 400,000 pixels ) , catch them at high speed moving objects , can cause image blur.
2 , monitoring
Network Camera : Built-in WEB, using a standard WEB browser on your PC , you can manage and view images. The ability to remotely manage and view images. Presence on the network camera can be remote image data hard drive, easy to find , easy to store, will not be destroyed.
Analog cameras : closed , only watch inside , not remote monitoring . Video data can only be stored locally , not remotely view , easily destroyed criminals .
3 , the bandwidth
Webcams biggest advantages formula simple wiring through the switch can be centralized transmission.
Analog cameras also need root network bandwidth , network bandwidth required to consider whether the actual on-site support .
4 , integration
Network Camera : multi-screen management software sharing , multi -channel monitoring , unrestricted ones , without additional hardware costs.
Analog camera : DVR ( ones with certain restrictions ) increase in the need to increase the front-end costs .
5 , the security
Network camera : the signal is encrypted , highly secure digital certificate , you can add the "Watermark " message . Fun at a distance of not affecting the image quality degradation leads to problems .
Analog cameras : low security , image transmission distance by the image .
In summary, the IP camera can be said to be comprehensive beyond the traditional analog cameras , due to the nature of its working principle difference between analog camera technology and the emergence of bottlenecks in the development of limitations , and the salient features of the network camera overcomes these restrictions. Currently the network camera has been developed for several years , the future of the world and certainly in the domestic Network camera .
