The next day.

Several detectives from the Criminal Police Team ran to the "old place" mentioned by Guo Yunxia and squatted there for a day, but they didn't see the monkey thief. Everyone was not discouraged.

For several old detectives, this was the norm.

The heroic style of robbing the execution ground was only in storybooks. After exposing their accomplices, those who reappeared were daring river bandits.

A man who would deceive a woman with a monkey still had the courage to do so.

The crowd speculated that the possibility of running in the opposite direction was greater.

Of course, the greater possibility was that he went to sell the monkey.

The detectives knew that releasing the animals was impossible.

However, the people involved in the case were not familiar with animal trading. While asking around, they also cast a net to search slowly.

In the evening.

Because of the warm invitation from Principal Heng Wenxuan, Jiang Yuan and Wei Zhenguo came to the second-floor cafeteria of Qinghe College to have dinner together.

Zeng Zhuohu also accompanied them at the same table, appearing friendly and amiable.

He was just a little nervous.

After playing hooky for a long time, there was a place where he was a little reluctant to play hooky.

For Zeng Zhuohu, the principal was a rare big leader, and it was the first time to drink at the same table.

Wei Zhenguo also reminded Jiang Yuan in a low voice before taking his seat: "The principal of the university is different from the principals of middle and elementary schools. It's a bit out of the ordinary."

Cao Yuan responded.

"I'm a villager from Jiang, and I'm a bit rough."

The dishes prepared by Qinghe College were also very delicate.

For the cafeteria, feeding the students to fatten them up to 10 catties was like preparing a good meal for the principal.

The chefs were also working very hard.

They even made some trendy molecular cuisine in the past few years.

Although it was delicious, it was indeed pleasing to the eye.

"How does it taste?"

Principal Li ate less, but he raised his glass to drink.

Jiang Yuan pondered for a moment and said, "It's quite ordinary."

Cao Yuan laughed and said loudly, "Is it too delicious?"

"Uh..." Jiang Yuan didn't expect the principal of Qinghe College to be so straightforward.

Just then, Principal Li said to himself, "The head chef over there is a relative of your Cao Yuan, and he really has a talent for cooking. It is said that he has also studied under a famous chef, but seasoning is not his strong suit."

At this point, Principal Li sighed and said, "The head chef is an ordinary and hardworking person, but also greedy... it's quite in line with the temperament of your school, and that's how it has come to today."

Jiang Yuan blinked as he listened, looking at the other leaders of Qinghe College at the same table. He thought to himself, could Principal Heng be drunk?

Was that something appropriate to say in public?

At that moment, the school leader sitting on the left raised his glass and said with a smile, "Principal Heng is straightforward and virtuous, and has a broad mind. I'll drink to you."

Principal Li smiled and drank with him.

The school leader then proposed to have a drink with Jiang Yuan and introduced himself, "You are Jiang Yuan, right?"

Jiang Yuan was not a drinker, but he still picked up the large wine glass.

The story, although short, made people want to drink.

Looking at Principal Heng's smiling and squinting eyes, Jiang Yuan suddenly thought, if this was a story to persuade someone to drink, it would be impressive.

In the past, when they were at the wine table, they would change the stories at the wine table to "lying flat is the best," "the war of the DINKs," and "anti-marriageism." The wine had to be drunk in a hurry.

And if there was no family to interfere, even if they got drunk, there would be no one to nag. The white wine would be drunk until it was numb.

Principal Heng waved his hand and had the dishes replaced, and then brought out a fruit plate and nuts. He also brought out a few cold dishes, and with a wave of his hand under the table, he smiled at Jiang Yuan and said, "Jiang Yuan, how is the monitoring system at your school?"

Jiang Yuan understood the direction and said discreetly, "It's relatively small and complicated."

"Small and sophisticated, right?" Principal Heng understood the meaning.

When the conversation reached that point, Jiang Yuan had to cover up and said, "Small is just small. If there are too few screens in the monitoring room, it's useless. It's necessary to have so few real-time monitoring screens."

Seeing that Principal Heng was paying attention, Jiang Yuan continued, "The monitoring system of Qinghe College is considered quite advanced. As far as I know, there are very few schools now, including small-scale industrial and mining units, where the monitoring can be unified. A small part of them have one monitoring room for one building, or one monitoring room for one area."

"Compared to that, the monitoring system of Qinghe College is relatively complete."

"If the storage system can be updated, the monitoring system should be at a level of about 60 points."Principal Li nodded in agreement, raised his glass in a toast, took a sip of the fiery liquor, and gasped before saying, "To think that such little effort only scores 60 points, are you content with that?"

Heng Wenxuan chimed in from the side, "Forensic Jiang, what would it take to score a perfect 100?"

Jiang Yuan was taken aback, pondered for a moment, swirled his glass, and smiled, "You're actually asking what your own surveillance system lacks compared to a perfect operating system, aren't you?"

"That's putting it too bluntly," someone interjected.

Principal Li laughed heartily, "But that's the gist of it."

The effects of the alcohol were now becoming apparent.

Jiang Yuan, after all, was part of the education system and had not been involved in the development of the surveillance system.

Knowing full well that the surveillance system was a piece of cake, Jiang Yuan, having had a lick of the pie, felt a sense of involvement.

After careful consideration, Jiang Yuan said, "Firstly, staff training is essential. Monitoring is one thing, but being able to track is another skill that must be mastered.

To score full marks, one must have the ability to analyze surveillance footage."

"Secondly, the equipment must be standardized. Their surveillance system, as you see, has been built over the years. There are two main issues: whether the cameras are from the same era and whether they are from the same manufacturer. If their protocols and codecs are the same, there should be no compatibility issues."

"The transmission lines also have similar issues.

Some of the older lines might be coaxial cables or twisted pairs, which, if too high-spec, could exceed performance requirements.

At the very least, low-resolution cameras should be able to meet the frame rate standards."

"Moreover, a single line can only support so many devices."

"And then there are the analog cameras; some of the surveillance can only be viewed, not recorded, which is another matter."

"As for storage devices... setting up a storage system is even simpler, focusing on performance, ease of use, and cost-effectiveness..."

"Of course, you're aiming for a perfect score.

Just speaking of your school's surveillance system, it's not that it's been done poorly."

Recently, Jiang Yuan had also studied surveillance systems and, with the addition of basic image enhancement, had managed to avoid issues affecting the entire system, so his insights were quite detailed.

Principal Li listened intently.

Heng Wenxuan, on the other hand, was not entirely convinced and said, "Such requirements for our school..."

"That's why it's a 100-point standard," Jiang Yuan interjected.

Principal Li stopped Heng Wenxuan and said, "The gap between us and Tsinghua is even smaller than that, right?"

Heng Wenxuan had no retort.

Principal Li took another drink, pondered for a moment, then smiled at Jiang Yuan, "Officer Jiang, you've been thinking about remodeling that surveillance system recently, could you be a consultant for it?"

Cao Yuan was taken aback, "Would that be appropriate?"

"Being a consultant for you is the same as being one for the school; there's nothing inappropriate about it."

Principal Li smiled naturally and added, "The professionals you know, some of them are also within our school system. There might be issues with their technical knowledge, but there's no conflict of interest, so you've always wanted to find an expert within the system."

"You're considered an expert."

Jiang Yuan humbly demurred.

"As a personal consultant, if you can provide some timeless advice, that would be satisfying."

Principal Li raised his glass with a chuckle.

Jiang Yuan followed suit and drank, his heart not entirely set on the idea.

As for Ningtai County's surveillance system, Jiang Yuan was actually quite satisfied with it.

The current situation was that local thieves were being caught less frequently, and occasionally, thieves from other areas would try to fill the void.

Of course, those big-time thieves from other places, every now and then, if there wasn't a murder case or they weren't out of town or on vacation, Jiang Yuan could take a few hours and sift out several to catch.

And don't listen to the media hype about big thieves being caught and then released.

In a small number of cases, this happens when the evidence is insufficient, or the case value doesn't meet the threshold of two or eight thousand.

If the case value exceeds 3000 and there's no evidence, then there's no reason to meet the KPIs just by delivering them to the door.

As for repeat offenders, under the current criminal law, they are especially likely to get less than eight years.

With Jiang Yuan's efficiency, the turnover rate of Ningtai County's foolish thieves, if any, was quite high.

However, Jiang Yuan's reputation was growing, and he was spending less and less time on local cases. The big-time thieves from outside the county still required the involvement of his colleagues, and that's when the strength of the surveillance system became apparent.

It wasn't like Jiang Yuan could be called upon for image enhancement for every little thing.

And in some cases, image enhancement was as straightforward as dealing with blurry footage from low-resolution cameras.

When it came to prosecution, it made things a bit simpler.

For major cases, clear and complete evidence was ideal, as it avoided complications that even defense attorneys would find troublesome.However, the construction of modern surveillance systems is not only cost-effective but also simple in terms of the bidding and building process: it's as easy as teaching a primary school class.

Jiang Yuan was also qualified to participate.

On the other hand, Qinghe Academy, with a scale larger than Ningtai County and a more complex system, lacked the financial and manpower advantages. It was a good choice for getting acquainted with something unfamiliar.

At that time, Jiang Yuan remembered the eighth-class merit medal he was about to receive.

Technically, a newly awarded eighth-class merit couldn't be used to select a new skill.

It had to be either a Level 2 minor skill or a Level 3 major skill.

Since he had no immediate plans, Jiang Yuan had put off the upgrade for the time being.

But now, he wondered if he could use it to learn a skill like Construction Defense (Level 3)?

After all, when he received a seventh-class merit next time, the skill from the eighth-class merit wouldn't be able to cover a reselection, and he would be at a loss either way.

"In this line of work, you can serve as a consultant for a few months."

Having thought it through, Jiang Yuan promptly agreed and then asked, "What do you want to do?"

Principal Li took out his phone with a serious demeanor and said, "Let's connect on WeChat.

Should he scan you, or you scan him?"
