Want to do well Security monitoring You should know these ten professional knowledge
An full monitoring is a multidisciplinary and multi technology comprehensive industry, involving computer technology, network technology, storage technology, engineering technology, optical imaging, control, transmission and other professional technologies.
In order to become a qualified an full monitoring technician, the installation of security monitoring project needs to reserve a large number of professional technologies, and the technicians need to have strong comprehensive technology application ability. Of course, some people will say that the current monitoring equipment is technologically advanced and can be used after mobile phone scanning. I can tell you responsibly that it is not advanced, it is simple. To get to the point, now we will not discuss the technical reserves of software and hardware product developers and engineering implementation personnel, but only the professional security monitoring engineering installation knowledge that an full monitoring technical support personnel or technical service personnel should have. Have the opportunity to discuss the technical knowledge of developers and engineers.
1. Computer and Network Technology
Familiar with computer hardware and The server 。 Be familiar with various operating systems of workstations and servers. Familiar with Windows, Linux and servers. The server hardware that provides you with a deployment management platform is basic.
Network technology has long entered the era of network video monitoring. Network technology is essential. The basic principles of network communication, network division, subnet mask calculation, NAT, DDNS, routing switching, and VLAN division all need to be familiar with. System debugging can not tell which one is needed. Unicast, multicast, and broadcast also need to understand what is going on in the broadcast storm, what is going on in the large-scale network congestion, and how to analyze it. UDP does not shake hands, and TCP does shake hands. Which way is good depends on the specific network environment, and these knowledge needs to be mastered. Web servers are no strangers. Now, any monitoring device is integrated or called a built-in web server. If you use a browser to configure IPC or NVR, you use the webservice of the device.
2. Database knowledge
A systematic and large-scale An full monitoring system will establish this platform, that platform or CMS. Whether it is B/s architecture or C/s architecture, the server side must have one or more sets of software, and the database must be well arranged. So it is very important to master some database knowledge. MSSQL, MySQL, etc. can deploy, operate and maintain databases.
3. Software application
Troika word/Excel/ppt of Office must be able to use. I don't know why. You need to use Visio to draw system diagrams and AutoCAD to view design drawings. Simple development tools are used well, and one or two of them will be useful to the field. SDK。 All equipment manufacturers will provide SDKs and secondary development kits. You can also learn about the SDK version and main library files.
4. Hardware Tools
Not all systems are networked, and tools such as multimeter, oscilloscope and line tester should be used at critical moments.
5. Monitoring equipment knowledge
Needless to say, we must be familiar with cam, DVS/DVR/NVR, streaming media, decoder, matrix, platform server and other devices. This is what we are doing.
6. Monitoring expertise
Understand and flexibly use the image, coding, compression, key frame, frame rate and code stream. Help you solve problems at critical moments.
7. Store knowledge
Network video monitoring can not be separated from storage. NAS/SAN/IPSAN understand that it can be achieved by giving you a storage device. RAID disk array, redundancy and hot standby should be able to pass.
8. Communication knowledge
Be familiar with various communication interfaces, protocols, RS232/485/422, etc.
9. Standards
The system scheme is to be implemented. How to implement it? There are also various specifications, projects, acceptance, networking, etc. Technicians need to know more. What is gbt28181, GB 50394, and GB 50395? At the critical moment, in addition to technology, we should also talk about the basics.
10. Engineering technology
The project quality and construction technology are one of the key factors for the success of the system. Not only the video monitoring system, but also other security systems and weak current systems. Engineering technology is the basic guarantee of system application.
Wuxi Dehang Technology Co., Ltd., founded in 2010, is a professional computer network system integration and weak current engineering service company.
For many years, the company has been committed to information system integration, Internet/Intranet software development, building a technical service network covering Quan country, and providing a complete set of solutions for large, medium and small users such as early planning, scheme design, application development, system installation and debugging, and personnel training of information systems and weak current systems. So far, it has provided hundreds of large and medium-sized computer network systems and weak current engineering solutions in the fields of finance, insurance, securities, power, banking, civil aviation, railway, water conservancy, petrochemical, national defense, customs, telecommunications, scientific research institutions, etc.
