The second generation of video surveillance is an analog-digital "monitoring system (DVR),This is now the general video surveillance,It is also the main thing that Zhang Chu is now producing。

This technology has only just started at this time, and it will not be until 10 years later, about 17 years or so, that it will be slowly replaced by new technology.

The "analog-digital" monitoring system is a semi-analog-semi-digital scheme with digital DVR DVR as the core, and the video signal is still output by coaxial cable from the camera to the DVR.

Through DVR, it supports both recording and playback, and realizes picture splitting and frequency division, and can support limited remote IP network access and other functions.

Compared with the previous CCTV, some functions have been expanded, such as support for playback, you can set up external network access on the server, and monitor the situation through the client access server.

However, in terms of equipment, various equipment support is still required. The scalability is also limited, and it is generally expanded in multiples of 8 or 16 channels.

"We will always pay attention to the latest technological progress in the world, and we will also learn new technologies at any time, and strive to keep our technology and products at the forefront at any time. ”

For Zhang Chu's words, the other three people all agreed. For these electronic products, if they want to develop well, it is necessary to master the latest technology, and they have always kept the same old book, which will be eliminated at any time.

The third generation of video surveillance is a full IP video surveillance system IPVS, this full IP video surveillance system Zhang Chu has also been contacted, and there are significant differences compared with the previous two schemes.

The new cameras have a built-in EB server and an Ethernet port directly available. Instead of generating images in the form of continuous analog video signals, these cameras generate JPEG or MPEG4 data files that can be accessed, monitored, recorded, and printed by any authorized client from anywhere on the network.

All cameras are simply connected to the network via cost-effective wired or wireless Ethernet, allowing you to leverage your existing LAN infrastructure without the need for additional cables.

Camera output images and horizontal, vertical, zoom (PTZ) control commands can be transmitted using a Category 5 network cable or wireless network, and power over Ethernet can be used directly.

This solution is easily upgradable and fully scalable, making it easy to add more cameras. In the future, the central server will be able to easily upgrade to faster processors, larger disk drives, and more bandwidth.

Of course, this thing is not without flaws, that is, the risk increases a lot after the Internet, and some hackers can control the camera by some means, and then reveal some things to the outside.

As for the fourth generation, the fourth generation Zhang Chu has not been in contact with it, but has only heard the introduction of this aspect. It's roughly based on cloud computing in some way, and he doesn't know much about other situations.

After spending an afternoon at Allianz Surveillance, Zhang Chu drove back to Dongzhen. His main business is still over there, and that's the point.

The above support policies have not yet been announced, and it is not clear whether Zhang Chu is qualified on his side. Mayor Huang talked to him a few times after he came up, but he didn't talk about support.

Obviously, this result has not come out yet, and the results obtained by Zheng Shuang's news channel are the same. In this regard, Zhang Chu had nothing to do, so he could only wait patiently.

However, the new project is operating normally, even without the support from above, Zhang Chu will be ready to do it himself. Naturally, he will not wait stupidly for support, and he is still doing what he should do. These projects have a future, and Zhang Chu himself has invested a lot of money into them.

Lu Huaqiao was transferred from the phantom to the online mall and was in charge of the affairs here. There are also Ma Xiaoyan and Zhang Chu above him, but Zhang Chu is just looking at it in the general direction, no matter what the specific things are, he won't either.

Although Zhang Chu can also program, the online mall is still a little different from what he knows. His skills are not enough, and he is now recruiting troops and horses with all his might, mining talents from Pengcheng, Modu and various universities.

There are not enough people to try to get what is in your mind, which is obviously unrealistic. Ma Xiaoyan knows a little about these, so she is doing the interview, and Lu Huaqiao is responsible for other things, and he doesn't understand technology.

Zhang Chu can help take a look at it here, but now that someone has been promoted here, when Ma Xiaoyan is not there, the person who replaces him can also arrange things here very well, and there are not many things that Zhang Chu needs to worry about.

The phantom is handled by Zheng Shuang, 3 This piece does not need to spend much effort except sales, and the technology here focuses on the understanding of various applications of new mobile phone technologies.

Some of the latest technology applications on the Pengcheng side will also be absorbed by this side, and then used on their own experiments. They can only do some integrated research and development now, and there are some things that they can't go deeper.

"Zhang Chu, I'm going to participate in the competition in Changsha District, there are more than a dozen family and friend group tickets here, do you want to come over?"

Not long after returning to Dongzhen, Huang Wen called Zhang Chu and asked Zhang Chu if he wanted to participate in her competition. Zhang Chu thought about it, as if he hadn't had anything to do recently, and he just happened to be going to talk about the branch over there, so he agreed.

There are not many people in the past, he can't be sure about this now, he has to ask first. has a good relationship with Huang Wen, and they have to add Zhang Yan on their side. Xu Li couldn't leave, and Ma Xiaoyan didn't know.

Zhang Chu also wanted to take his parents to Changsha for a walk, and by the way, take a look at Orange Island, Xiangjiang River North, and Yuelu Mountain. Now that you've earned your own money, wouldn't it be nice to take them around a lot?

What was not possible in the previous life, now all the things are made up. Let the two of them have less regrets in their hearts, and let them see the great rivers and mountains of the motherland.

After thinking about it, Zhang Chu first asked Wang Xiaofan Yangming about them. Wang Xiaofan couldn't leave, his wife's belly was getting bigger and bigger, and there were things at the company and the counter.

Yang Ming is the same, he happened to have a big project he was interested in recently, and now he is in full negotiation, and he wants to take this big project down.

Only Liu Wei is going, and his girlfriend will follow. Zheng Shuang and the others will also go, Ma Xiaoyan has no time, and Zhang Yan will follow. plus Zhang Chu's parents and Zhang Chu, as well as Huang Yan, there are nine people together.

Xu Ke has been there with Huang Wen a long time ago, and he is more interested in Huang Wen's participation than Zhang Chu. According to Zheng Shuang, Xu Ke has resources in this area, and if she helps Huang Wen, it will be of great benefit to Huang Wen.

Zhang Chu didn't understand this kind of thing, so he didn't ask much, but he also hoped that Huang Wen would get better and better. Huang Yan was a little surprised to receive Zhang Chu's invitation call, she had always taken the initiative to chat with Zhang Chu, and Zhang Chu was basically busy.

It was rare for Zhang Chu to call herself and invite herself to watch the singer audition together, she was still very happy in her heart, and agreed to take a sip of wine.
