I used to be a security guard, and I did it myself. (Start your own business, set up your own) Tell me about my experience.

We don't discuss sales knowledge, but it's actually very simple to monitor this together. Security includes many things, such as access control system, indoor and outdoor burglar alarm system, parking lot management system, perimeter prevention system, intelligent community system, etc. )

Monitoring several blocks: camera, 2, monitoring host, 3, transmission medium, remote monitoring.

1, camera, including the size of the lens, how wide it can be seen, how far it can be seen, etc.

2. If the monitoring host is embedded, buy one, just like buying a brand computer. If you assemble it yourself, you should consider how many acquisition cards to buy and whether it is compatible with the computer motherboard. You should also consider the storage time of the video and how many hard disks you need. These are all calculable.

3. There are several kinds of video lines, and then nine buttons (that is, the connectors of video lines) are welded or screwed together with the video lines.

4. Then realize remote monitoring. No matter where others are, you can see real-time monitoring or play back or install a client on a web page.

I'm talking about all the knowledge that you must know to operate safety sales (you don't have to master it completely, at least you have to know these processes)
