With the development of science and technology, the maturity of computer network technology and communication technology, and the popularity of the Internet, a new generation of surveillance products - network cameras have emerged. The network camera, with its beautiful appearance, exquisiteness, easy installation, simple operation and perfect functions, will become the terminator of the DVR. The advantages of the three-point network camera are as follows:
Easy to use
Network cameras are easy to use. Whether you have installed Windows 98, Windows 2000, or Windows XP or a Linux operating system on your personal computer, you can directly enter the network by using an Internet Explorer 5.0 or later browser or a Navigator 4.0 or later browser. The IP address of the camera is used for monitoring purposes. The user-friendly operation interface allows the operator to do whatever he wants with just one finger movement. Even a layman can easily navigate.
real time
Smooth effects and high definition have always been the highest realm pursued by surveillance. The network camera is second to none in domestic network cameras because of its standard VGA format resolution of up to 640*480 and browsing speed of 25 frames per second. The adopted MJPEG, MPEG4 compression format minimizes the bandwidth required for transmission, and the viewed image effects can be comparable to digital video cameras. Registering different controls can better capture videos in the MPEG compression video stream format, making the playback effect immersive.

The installation of traditional monitoring equipment is complicated, the laying line process is cumbersome, and the workload of installation and debugging is large. Network cameras are exceptionally simple, especially for some government departments, schools, large and medium-sized enterprises, etc. As long as they are slightly expanded on the basis of their original computer networks, they can install the network cameras randomly, reducing unnecessary Construction engineering and additional maintenance save manpower and material resources. Not only is it widely distributed, but it also facilitates centralized management. Network cameras also support dynamic IP networks. Using a free dynamic DNS server or a third-party dynamic host software, you don't have to worry about the fact that the virtual IP address is constantly changing and you cannot find the camera.
The network camera is a rookie of video surveillance. There are still imperfect aspects behind its strong vitality. There are external and internal boundaries, such as network delay and so on. Because there are still various problems to be solved in China's current network application environment, the advantages of network-based products, such as network cameras and video servers, cannot be fully realized. The improvement and development of networks have become bottlenecks in product development. Network disconnection and congestion are also common network problems. In order to avoid the loss of data caused by this, some manufacturers have built-in alarm image buffers in their products. When the network is briefly disconnected or blocked, the buffer can be temporarily stored. On-site image data, to ensure that important data is not lost, for particularly important places, this can be solved by recording the front and back end simultaneously. Some manufacturers also use special routers on the network cameras and video servers to automatically dial up the Internet in the event of a disconnection and keep the network open.
Network cameras will replace DVRs. This will be a fierce struggle. After all the dust has settled, who will be ups and downs, we will wait and see.
