Security monitoring equipment selection guide
Security monitoring equipment selection guide
2010, enterprises have to spend a lot of video surveillance equipment, and some businesses are still waiting to see. Then the video monitor to what direction will it? The face of uneven monitoring products, enterprises in the end how to buy it? Article to answer your questions! Video surveillance to what direction will it?
Buying guide
1. Practical. System should take into account local environmental conditions, monitoring objects, monitoring methods, maintenance and investment and other factors, to meet the city video surveillance alarm network systems up and running and public safety needs.
2. Reliability and stability. System should be mature technology and reliable equipment, key equipment for backup or redundancy measures. System software to safeguard the security capabilities and strong fault tolerance and system recovery capabilities to ensure the stability of the system as long as possible, once the system failure can be repaired or restored as soon as possible.
3. Scalability. Should adopt the distributed system and modular design to adapt to the system of the expansion, functional expansion, supporting the demand for software upgrades. Users may always need to be expanded or cut on the system, reflecting the flexibility.
4. System upgrades and maintenance convenience. Because the system larger, system software and core equipment should have automatic upgrade and maintenance functions; In addition, the city network alarm monitoring system is composed by a number of complex systems, including network, storage, operating system, platform software, a variety of front-end equipment , so each sub should have a working log records, including system modules and core equipment.
5. System management functions and ease. Taking into account the size and complexity of networked systems, management software platform should have a better system architecture, system management and core business management must be clearly separated to ensure that meet different application requirements. Because the system in various management server , storage and forwarding server, and so a larger number of network management functions so that the system must be strong, otherwise it is impossible for routine maintenance; system provides management and user interface should be clear, concise, friendly, and control should be simple , flexible, easy to use, easy to manage and maintain.
6. The system supports the ability of secondary development. A city camera monitoring and alarming number of networked systems there are at least several hundred up to tens of thousands more, it must take into account the sustainable development platform. To achieve "video to create value," the goal, requires a system with secondary development of the condition, the only way to insure the full utilization of video resources.
7. Advanced and inheritance. Urban video surveillance alarm network system is not possible to the original building to simulate based system Yigai abandoned, the appropriate approach is a good all-digital in the planning system as far as possible under the premise of the original analog system incorporated. The ideal system is seamlessly between the two can form a complete network of urban video Surveillance Equipment.
8. Cost performance. Designers should be reasonable to set the system functions correctly the system configuration and equipment selection, the key premise of good quality equipment to ensure the system's overall price is lower, so that the system has a higher cost. The front of the camera system and back-end software, the level of selection should be the focus of attention, if the number of front line than the camera 460 lines, no matter how good the follow-up system does not help, it is impossible to ensure that the system has a clear image effect. In some applications need to have wide dynamic range and other advanced features.
9. The system security level. System security includes many aspects, mainly to prevent the access of illegal users and devices, so in addition to the different users (including administrators and users) to take different levels of authentication methods, but also to ensure that the equipment can not access illegal into the system. Network video surveillance systems most vulnerable to hacker attacks, should take effective security measures to prevent the system from illegal access, illegal attack and virus infection. Also need lightning strike, overload, power failure, electromagnetic interference and vandalism and other factors of insecurity, in order to provide comprehensive and effective security measures.
10. Compatibility and standardization. Is to achieve compatibility with many different vendors and different interconnection agreement between the key device. System should be able to effectively communicate and share data, equipment or systems as much as possible to achieve compatibility and interoperability. The higher degree of standardization of the system, open the better, the longer the life cycle of the system. Control protocol, transport protocol, interface protocols, video and audio codecs, video and audio file formats should be consistent with relevant national standards or industry standards.
