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 should 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. Unicast, multicast and broadcasting also need to be understood. What happens with broadcast storms, what happens with large-scale network congestion, can be analyzed, UDP is not a handshake, TCP is a handshake, which method is better depends on specific network environment, this Knowledge needs to be mastered. WEBSERVER is no stranger either. Now any monitoring device is integrated or called built-in WEBSERVER. You use a browser to set up an IPC or NVR and you use device's WEBSEVICE.
Secondly, 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.
8. Communication skills
Introduction to various communication interfaces, protocols, RS232/485/422, etc.
9. Standards
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 Technologies
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.
