How to judge the quality of the security system

Security systems have a wide range of applications in our lives. How do we judge the quality of security systems in our lives? The following points can be used as reference points:
First, practicality
The system should take into account local environmental conditions, monitoring objects, monitoring methods, maintenance and investment scale, etc., to meet the needs of the normal operation of the urban video surveillance alarm network system and social public safety management.

Second, stability
The system should use mature technology and reliable equipment, and have backup or redundancy measures for key equipment. The system software has maintenance support capability and strong fault tolerance and system recovery capability to ensure that the system runs stably for as long as possible, and can be repaired or restored as soon as the system fails.

Third, advanced
The construction of the urban video surveillance alarm networking system is unlikely to abandon the original analog-based system. It is appropriate to include the original simulation system as much as possible under the premise of planning a fully digital system. The most ideal system is to make a seamless connection between the two to form a complete urban video image network monitoring.


Fourth, the performance price ratio
Designers should reasonably set system functions, properly perform system configuration and equipment selection. Under the premise of excellent key equipment grades, the overall price of the system is guaranteed to be low, which makes the system cost-effective. The camera selection at the front end of the system and the level of the back-end software should be the focus of attention. If the number of lines of the front-end camera is lower than 460 lines, the subsequent system is no good, and it is impossible to ensure that the system has clear image effects. Advanced features such as wide dynamic range are also required in some applications.

V. Convenience
Due to the large scale of the system, the system software and core equipment should have automatic upgrade and maintenance functions. In addition, the urban monitoring and alarm networking system is composed of multiple complex systems, including network, storage, operating system, platform software, various front-end equipment, etc. Therefore, each subsystem is required to have a work log record, including system modules and core devices.

Sixth, the degree of standardization
Compatibility is the key to interconnecting devices from many different vendors and different protocols. The system should be able to communicate and share data efficiently, as much as possible to achieve compatibility and interoperability between devices or systems. The higher the degree of standardization of the system and the better the openness, the longer the life cycle of the system. Control protocols, transmission protocols, interface protocols, video and audio codecs, video and audio file formats, etc. shall comply with the corresponding national standards or industry standards.

Usually used the suitable for transport by sea, rail, air and other suitable for import and export customs clearance of free fumigation wooden box or free fumigation wooden pallets (precision products used the collision cladding coating layer in the packaging box , to ensure the goods safe enough)

   Flange is an element connecting pipe to pipe, which used for connecting one pipe end to another. Equipment import and export for two devices is also connected to each other by a flange, gasket and bolt as a group of combined sealing structure of detachable connection. The flange is used in pairs, low-pressure pipeline can use Threaded Flange, pipeline pressure above four kilograms should use welding flange. Flange with different pressure is attached with different bolt.
