…
After Liu Kuaixiang made the arrangements, he came back to accompany them for tea and chat. About forty or fifty minutes later, a man came over holding a cardboard box.
When Wang Zhaozhao and Xu Yanni were counting their things, the man looked at Xu Zifu and the others a few more times and started talking to them.
It turned out that he had been discharged from the army with injuries, and his injuries had almost healed, so he was now waiting for assignment.
I have been recuperating from my injury for more than half a year, and I am still idle after I have recovered. I feel really uncomfortable, so I came to my cousin Liu Kuaixiang to help run errands.
Xu Zifu just thought that he was taking a break, and knowing that his sister was coming to the electronics market, he came to go shopping together.
Then he changed the topic and prevented him from paying too much attention to Zhao Mai and Dapin.
After Wang Zhaozhao and the others had counted the things, Liu Kuaixiang took out an abacus, did the math, and said it was thirty-two yuan.
Thirty-two yuan sounds like a lot, but some of the things Wang Zhaozhao and the others wanted were probably not cheap.
Under the current conditions, she and Xu Yanni discussed making a simple one first, using a camera and a monitor, connected directly via cables.
As for formal monitoring, their goals are a bit too big, so they must apply for a project before they can carry it out.
In addition to the cooperation of professional laboratories and personnel, it is also necessary to apply for registration.
You can't do it privately.
"Uncle Xiang, you...don't help me in vain, but end up suffering a loss?" Wang Zhaozhao looked at Wang Sibing uncertainly.
"I can't suffer a loss. However, as your fourth uncle and I are such good brothers, how can I make money from you, my niece?" Liu Kuaixiang was also straightforward.
"I understand, Uncle Xiang, you only collected the money for the goods from other shops. You didn't make any profit, and you didn't charge any order fees. You haven't charged for the resistors in your shop yet."
"Haha, the fourth brother wasn't bragging, his eldest niece is amazing."
Wang Sibing loved hearing this and started to brag. "That's right! My eldest niece and her classmates are the best of the best... Come on! Brother Xiang, we're going back today. We'll treat you to dinner another day."
After talking and paying the money, Wang Sibing took Wang Zhaozhao and the others away.
It must be said that he was very curious and looking forward to what kind of doorbell Wang Zhaozhao would make.
Xu Zifu was also very curious, but he only had three days off and returned to the team the next afternoon.
Only his younger brother saw him off. His younger sister was in Wusi Hutong and didn't come back last night.
The east wing where Wang Zhaozhao lives is used as a study and studio, but the studio is not yet large enough for them to use formally for experiments.
So, the two of them discussed it and called Professor Zhou to ask if they could borrow the school’s laboratory.
Of course you can!
Professor Zhou even took time out to return to school and wait for them.
"...You guys really can't sit still." After chatting with Wang Zhaozhao and Xu Yanni, Professor Zhou sighed with a mixture of laughter and tears.
“We don’t really want to.”
In front of Professor Zhou, they are now somewhat "releasing their true nature".
Professor Zhou, "Just say it in front of me. If you say it outside, you'll easily get hated. Don't let anyone know you'll end up getting put in a sack and beaten up, and you won't even know who it was."
"It was possible before, but it's difficult now." Xu Yanni said with a smile.
"...Look at how capable you are. That's enough! Go back to your work." Professor Zhou's eyes hurt when he looked at the two students.
After a pause, he continued, "Regarding the surveillance... I'll make a phone call for you to find out the situation."
He didn't know what arrangements the leaders had made, but given the security guards, he knew it wasn't going to be simple.
However, he believes that monitoring is useful and needs to be taken seriously.
"Thank you, teacher."
Wang Zhaozhao and Xu Yanni thanked Professor Zhou in unison, but they didn't bow exaggeratedly for fear that Professor Zhou would smash the teacup.
They took the key to the laboratory, asked Zhao Mai and Dapin to help deliver the things they brought, and then plunged in.
It is said to be simple to use a camera and a monitor, connected directly via a cable.
That is, the device captures and transmits video through analog signals.
And they need to work hard on the processing and storage of tape recordings...It is for simple household use and does not need to be kept for too long, but Wang Zhaozhao hopes to keep it for a while.
What if I need to check?
When they were engaged in the experiment without sleep or food, Professor Zhou, who called to inquire about the situation, was called to a meeting.
Regarding the 'surveillance' project that Wang Zhaozhao and the others were planning to do, hey! It's quite clever and coincidental, and it can be connected to the next mission.
Therefore, the simple video surveillance system that Wang Zhaozhao and her colleagues have now been listed as a concern.
When they came out of quarantine, the leaders of the research center were the first to receive the news.
At the same time, someone contacted Zhao Mai, Dapin and others to pick them up and take them to the research center.
Wang Zhaozhao: “……!”
Xu Yanni: “……!”
However, let them go home and wash up.
Finally, I washed up in the dormitory.
Fortunately, their dormitory 210 is still their dormitory 210.
I didn't make room for them just because they hadn't been back for nearly a year, or because they were graduate students and had to move to the graduate dormitory.
…
At the research center, Deputy Director Haodajie went downstairs in person to pick people up.
"Do you need some time to prepare?"
"It wasn't considered a formal research project, so there was only a draft, no formal report. If it was just an oral presentation, there would be no need to prepare."
"Just an oral report will do... I don't think you need to make any special preparations." The good deputy director said with a smile.
So, the two of them were taken directly to the conference room where the report meeting was held.
When Wang Zhaozhao and the others took out the things brought by Zhao Mai and the others and were debugging the connections, participants began to enter one after another.
Eh?
Wang Zhaozhao and Xu Yanni, who were busy, were both stunned when they saw Xu Zifu following a middle-aged man.
However, I just took a quick look and continued working.
They had guessed it a long time ago, hadn't they?
Ten minutes later, the equipment was connected and debugged, and the attendees had arrived. Let's get started.
The tacit understanding between Wang Zhaozhao and Xu Yanni does not require rehearsal, and they can work together to produce the best results.
After the presentation, it is customary to have a discussion and ask questions.
"You seem to think this is a very simple work?" asked the middle-aged man who appeared with Xu Zifu.
"Well... to be frank, it's indeed relatively simple for us."
The person who answered the question was Xu Yanni. She tried her best to be humble, but it was a bit difficult.
However, it can be explained that "the main thing is that the more important one is the acquisition and transmission of analog signals.
In the first half of the year, due to the needs of other projects, we made a breakthrough in analog signal technology...
The saying "one way leads to a hundred ways" is also applicable here."
"That immodest thing you said...it's indeed immodest. However, you don't need to be modest at all."
Ah, this...
Xu Yanni said that this was a bit difficult to respond to.
