Advantages of network video surveillance

Compared with traditional video surveillance, network video surveillance is more convenient for computer video information compression, storage, analysis, display, and alarm and other automated processing, thus realizing unattended; through the network platform to achieve a long-distance monitoring, even thousands of kilometers away from the scene of the effect can be achieved in person; the use of advanced software systems not only in a few minutes will be able to complete the traditional video surveillance in a large number of data analysis, improve the monitoring efficiency, and can obtain more realistic, clear digital image quality and more convenient, practical monitoring management and maintenance. A large number of data analysis, improve the monitoring efficiency, and can get more realistic, clear digital image quality and more convenient, practical monitoring management and maintenance. In short, network video surveillance is a computer, network, communications and video codecs and other high-tech integrated products.

Usually, analog cameras need to be connected to the back of a lot of wires, respectively, to transmit video and audio signals. Analog signal processing and management in the back-end there are many drawbacks. In the digital management platform, analog signals need to be converted into digital signals to be stored, archived, queried, to access the query, and often need to be restored to analog signals. Faced with real-time queries, cross-departmental real-time information **** enjoy complex needs, analog video surveillance data processing inefficiencies are exposed.

The main advantages of network video surveillance:

Efficient remote monitoring

If you need to realize cross-regional remote monitoring, you should prefer network video surveillance system. Of course, some hard disk recorders also have the function of network transmission, but the hard disk recorder is focused on local video, remote transmission efficiency is far less than the network camera, network video server, software features are not perfect. Network cameras, network video servers, is designed to achieve remote monitoring and design, network transmission efficiency is very high, and its client software is more professional than the VCR software, much better.

Using the original LAN, there is no need for another video cable

The implementation of the traditional monitoring system is to specialize in laying video cables, audio cables, control lines. Large enterprises and institutions, usually covers a large area, laying these lines time-consuming, laborious, expensive, while the network monitoring system does not require special wiring, you can use the enterprise's original LAN to transmit video, audio and control signals, the installation of more convenient.

Multiple people can monitor at the same time, without the need to monitor the center

Traditional monitoring systems need to set up a monitoring center, the unit manager if you want to view the monitoring screen or view the video data, you must run to the monitoring center. If you install a network video surveillance system, you can use your own computer to monitor the real-time picture or view the video data in your own office. And multiple managers can monitor each other without interfering with each other.

Centralized management of multiple images

Traditional surveillance systems, each DVR can only manage up to 32 images. While network video surveillance greatly crosses this limit, a computer host can manage thousands of images, giving full play to the advantages of centralized management.

Distributed architecture, easy to install, easy to expand

Traditional surveillance systems use a centralized architecture, all the video cables, audio cables, control lines to the monitoring center, such as to increase the number of cameras need to be rewired. If you want to relocate the monitoring center, the project is huge. Network video surveillance system is a distributed architecture, each network camera, video servers distributed in different parts of the unit, and surveillance video host can be located anywhere in the unit, connected to the network cable. To increase the number of cameras, transfer monitoring host, can be carried out at will, there is no constraint.

A collection of listening, broadcasting, alarm, remote control, etc.

Network video surveillance products not only transmit images, but also a collection of functions, and these signals are all transmitted through the network, without additional wiring.

Specific functions are as follows:

Listening -- the monitoring center can listen to the sound of multiple front-end devices

Broadcasting -- the monitoring center can choose to shout to multiple front-end devices

Intercom You can link the corresponding video window pop-up, video recording, electronic map flashing, and even link the camera to the corresponding angle

Remote control - network cameras, network video servers have alarm output ports, the monitoring center can control the output port output signals, which can be used to control the electrical appliances on and off
