Look at remote monitoring to understand the top ten technical issues
1. What is network video surveillance?
Network video systems generally refer to IP surveillance systems for specific applications in the field of security surveillance and remote monitoring. The system enables users to perform video surveillance and video image recording and related video recording over IP networks (LAN/WAN/Internet). Alarm management. Unlike analog video systems, network video systems use networks instead of point-to-point analog video cables to transmit video and other monitoring-related information.
2. What features of the network video surveillance system?
The main functions of the network video surveillance system include remote image control, video recording, storage, playback, real-time voice, image broadcasting, alarm linkage, electronic map, PTZ control, data forwarding, photographing, and image recognition.
3, network video surveillance can be applied to what aspects?
Mainly used in road monitoring, residential monitoring, Internet cafe monitoring, safe city and other industries users of small and medium-sized enterprises and home users.
4. What are the current mainstream network video surveillance products?
There are two kinds of network video servers (DVS) and network cameras (IPCAM).
5. What is the difference between network video surveillance system and traditional video surveillance system?
Traditional closed-circuit monitoring systems (including DVR-based area monitoring systems) adopt video cables or optical fibers to transmit analog video signals. They are very sensitive to distances, and long-distance transmission across regions is not economical and convenient (compared to network video surveillance systems. - Network Video Surveillance. Generally, centralized surveillance is performed in a local area. Long-distance transmission is generally performed in a peer-to-peer manner. The wiring of the entire system is large, the structure is complicated, power consumption is high, and costs are high. Many people need to be on duty; The overall system management is less open and intelligent.
The network video surveillance system adopts a flexible lease method (mainly adopts an IP broadband network), and multiple users can share a set of central control platforms. Users can easily input and use the software, and users can remotely browse and control. In principle, any place where the Internet can be accessed is available. Can browse and control. Many new digital technology achievements (such as image recognition technology) have also been introduced to make up for the inadequacies of traditional video surveillance systems, providing value-added service capabilities, extending the capabilities and scope, and improving the system's performance and intelligence.
6. What are the advantages of network video surveillance system compared with analog closed circuit system?
The information flow and media stream of the network video surveillance system are digital and independent. The hardware and software adopt the design concepts of standardization, modularization and scale. The configuration of the system equipment has strong versatility, good openness, and flexible system configuration. It has the advantages of perfect control function, convenient data processing, easy use, and simple installation, debugging and maintenance of the system. At the same time, the scale of IP and digital products will bring cost advantages.
7, network video surveillance system software platform can achieve the function?
Network video surveillance system platform can achieve centralized monitoring and management, video distribution, alarm linkage management, video storage management, system log management, remote video playback and viewing.
8. What is the cost of the initial investment?
The original analog monitoring system can be reconstructed by opening access network lines and installing video servers and other related equipment to implement related functions of the network video surveillance system. In this case, the cost that the user needs to invest is the equipment investment that it bears, mainly the cost of the video server. Because of the different types and specifications of the video server, the specific commitment cost must be negotiated with the local customer manager.
9. How to handle the original equipment using network video surveillance system? Do you not increase the cost of use?
The original equipment can be retrofitted with old ones, but additional equipment such as video servers, access lines and network equipment must be added. Old renovations only involve one-time expenses and will not increase daily use costs.
10, install the client software, or use the browser to access the system's full functionality?
There are two ways of using CS/BS, namely, installing dedicated clients and using them directly or through IE browser (need to download related plug-ins) to use all functions directly.
