install Wuxi Security Monitoring Knowledge required for engineering
Wuxi Security monitoring Wuxi has always been a fast-growing industry, especially with the popularity of AI and big data, and its security monitoring has reached an unprecedented height.
Many people think that the installation of monitoring is a very simple thing. Home cameras bought from a treasure can be installed by themselves. But today we are talking about a security monitoring technician, who needs to be familiar with the technical problems of the security monitoring system and know how to operate on the ground, rather than just installing a camera.
1、 Computer and network technology
For computers The server You should be familiar with the hardware of Windows, Linux and SERVER. It is basic that you can deploy a management platform with a server hardware.
Network technology has already entered the era of network video monitoring. Network technology is necessary. Basic network communication principles, network division, subnet mask calculation, NAT, DDNS, route switching, and VLAN division should be familiar. System debugging can't say which one to use.
Unicast, multicast, and broadcast also need to understand what is going on in the broadcast storm, and what is going on in the massive network congestion. It can be analyzed that whether UDP does not shake hands or TCP does shake hands is good. It depends on the specific network environment. These knowledge should be mastered. WEBSERVER is no stranger. Nowadays, all monitoring devices are integrated or called built-in WEBSERVER. If you configure IPC or NVR with a browser, you use the device's WEBSEVICE.
2、 Database knowledge
Systematic and large-scale security monitoring systems will build this platform, that platform or CMS. Whether it is B/S or C/S architecture, SERVER must have one or several sets of software, and the database must be arranged. So it is very important to master some database knowledge. MSSQL, MYSQL, etc., can deploy, operate, and maintain databases.
3、 Software application
The OFFICE Troika WORD/EXCEL/PPT should be able to use it. The reason will not be explained. VISIO shall be used to draw system drawings and AutoCAD shall be used to see design drawings. These two softwares shall be skillfully operated. Simple development tools can be used well, but if they can't be used, they can also understand some useful scenarios. SDK， All equipment manufacturers will provide SDKs, secondary development packages, and basically understand the SDK version and main library files.
4、 Hardware Tools
Not all systems are networked, and tools such as multimeter, oscilloscope, and line measuring instrument should be used at critical moments.
5、 Monitoring equipment knowledge
Needless to say, CAM、DVS/DVR/NVR、 Streaming media, decoder, matrix, platform server and other devices must be familiar with each other. This is what we do.
6、 Monitoring expertise
Imaging, coding, compression, key frame, frame rate, and code stream should be understood and flexibly used. Help you solve problems at the critical moment.
7、 Storage knowledge
Network video monitoring can not be separated from storage. NAS/SAN/IPSAN should understand that you should be able to handle it with a storage device. RAID disk array, redundancy and hot standby should be able to work out.
8、 Communication knowledge
Familiar with various communication interfaces and protocols, RS232/485/422, etc.
9、 Norms and standards
The system scheme is to be implemented. There are various specifications, engineering, acceptance and networking. Technicians still need to know more about it. What does GBT28181, GB50394 and GB50395 say? At the critical moment, we should not only be technically competent, but also be grounded.
10、 Engineering technology
Project quality and construction technology are one of the key factors for the success or failure of the system, not only the video monitoring system, but also other security systems and weak current systems. Engineering technology is the basic guarantee for the application of the system.
