Security monitoring has always been a booming industry, especially with popularization of artificial intelligence and big data, security monitoring has risen to unprecedented heights.
Many people think that installing a video surveillance system is a very simple matter. You can install a home camera purchased from a certain store, but security watcher we're discussing today needs more than just installing a camera. It's so simple, but we are familiar with technical issues of security monitoring system and know how to operate it on ground. So do not complain about low wages of weak electricians, if you own these 10 items of knowledge, authorities will take initiative to raise your salary.
1. Computer and network technologies
Be familiar with computer and server hardware, be familiar with different operating systems of workstations and servers, be it WINDOWS, LINUX or SERVER, you must be familiar with it, and server hardware can deploy a management platform for you. D., those are basics.
Network technology has already entered era of network video surveillance. Network technologies are essential. You should be familiar with basic principles of networking, network partitioning, subnet mask calculation, NAT, DDNS, routing switching, and VLAN partitioning. it's hard to tell which one is used to debug system.
Also refer to unicast, multicast, and broadcast. What happens to broadcast storms and what happens to large-scale network congestion can be analyzed. UDP does not handshake, and TCP does not handshake. Which method is best depends on particular network. This knowledge needs to be mastered in environment. WEB SERVER is also no stranger, now any monitoring device is integrated or called built-in WEB SERVER, you use browser to configure IPC or NVR, you use WEB SERVICE of device
Second, knowledge of databases
A complete system or a large scale security monitoring system will have a platform or CMS, whether it is a B/S or C/S structure, server must have one or more software suites and a database. should be arranged. Therefore, it is very important to have some knowledge about databases. MSSQL, MYSQL, etc. can deploy, operate, and maintain databases.
3. Software Application
Triple WORD/EXCEL/PPT of OFFICE should be able to use, reason is not to say. VISIO must be used to draw system diagrams, and AutoCAD must be used to view design drawings. These two softwares must be used skillfully. Simple development tools are best used and if you can't use them there are a few things you need to know and there will be useful scripts. SDK, each device manufacturer will provide an SDK, a secondary development kit, most basic can also understand SDK version, main library files.
Fourth, hardware tools
Not all systems are networked. Tools like multimeters, oscilloscopes, and linear meters are still useful at critical times if you know how to use them.
5. Monitoring hardware knowledge
Needless to say, CAM, DVS/DVR/NVR, streaming media, decoder, matrix, platform server and other equipment should be familiar and familiar again. This is what we do.
6. Expertise Monitoring
Image, encoding, compression, keyframe, frame rate, codestream all need to be understood and used flexibly. We will help you solve problems at critical moments.
Seven, store knowledge
Network video surveillance is inseparable from storage. You must understand NAS/SAN/IPSAN and be able to work with storage device. RAID disk arrays, redundancy and hot backup must be available.
VIII. Communication skills
Introduction to various communication interfaces, protocols, RS232/485/422, etc.
You need to implement a system solution and learn how to implement it. There are various specifications, design, acceptance and networking. The technical staff still needs to understand more. What are GBT28181, GB50394 and GB50395 talking about? At a critical moment, in addition to strong technology, there must also be evidence.
10. Engineering Technology
The quality of engineering and construction technology is one of key success factors of system, not only for video surveillance systems, but also for other security systems and low-voltage systems. Engineering technology is main guarantee of application of system.
