Ah Chai was not shocked, he looked at Liu Pengcheng carefully, then nodded and agreed.

Although he didn't know whether Liu Pengcheng's plan was right or not, in fact, Achai did too many things with a 1% possibility, and sometimes the case was handled by piecing together one by one.

Moreover, Liu Pengcheng actually knew Liu's pseudonym, which Ah Chai hadn't thought of before. He could be sure that Liu Pengcheng must know something, but he didn't plan to ask, this tacit understanding was there.

After Achai hung up Liu Pengcheng's phone, that afternoon, he took a plane and landed at Liangjiang Airport, accompanied by two other people, both of whom looked very ordinary, and no one would take a few more glances when walking on the street. Before leaving, Liu Pengcheng gave Ah Chai a box, which contained his computer, which might come in handy.

In 2001, Guicheng was still an emerging tourist city, and the construction of high-rise buildings on Zhongshan Road had just begun, and the suburbs looked like nothing. At this time, the Cross Street-Cultural Palace is a big construction site, and Xionghu Villa is also a hot time, and foreign tourists have to go to see it.

Achai and others have their own news channels, and they have mastered the three largest emerging villa areas in Gui Province before they came, and they began to investigate after landing on the same day, checking the sale, residence, and rental of villas in the name of buying houses.

It's already night, and the simple verification has found nothing, and Achai knows that there may be an action on the Dao County side tomorrow, but he speculates that the action has nothing to do with Liu, because this kind of thing is purely a small fight in Liu's eyes, and the manpower over there is quite sufficient, and now the place where the strength is empty is Qingxi. Of course, Liu Pengcheng is in Qingxi, which is reassuring.

Liu Pengcheng was sitting in the office at this moment.

He held a new map of Katsura City in his hand and pondered. He didn't know which neighborhood Liu was in at all, but he remembered that he was in a certain villa. From the perspective of the development of Gui City, villas are emerging products, and there are not many villas that can already be lived. In other words, the carpet search is very simple, and Achai and the others can finish it as soon as tonight.

He knows Achai's habits, and Achai is tireless when he encounters cases. Thinking about it, he took out his mobile phone and dialed Zhang Tao's number.

"Willow Bureau? What's up? Zhang Tao was a little surprised, because it was not early.

"There's something very important that I need your help with, but. I have to ask first, where is the development of your Eagle Eye system? ”

The last time I handled the case with Director Li and others, at the case summary meeting, Liu Pengcheng proposed several development directions. The first is about the number of monitoring and monitoring channels, the second is about technology development, and the third is about technology promotion. Among them, Liu Pengcheng proposed that the Kingdom of David has begun to use the Eagle Eye system with facial recognition in key locations, and we should also learn and introduce it.

"Which step are you asking?" Zhang Tao has great respect for Liu Pengcheng.

He only knew that Liu had lived in the villa in Guicheng for four years, and whether he had left or where he had gone during that time, and he was completely unclear about these details. Relying only on Achai and others is not only difficult, but also risky, at this time, the power of the map detective still has to be used.

In a blink of an eye, a year has passed, and Liu Pengcheng doesn't know if this system has appeared, if so, it will be of great help to the case handled by Achai in Gui City.

"Can face recognition be applied in actual combat?"

"Now it's version 3.3, and the technology of face recognition is still in the experimental stage, and the accuracy is not guaranteed." Zhang Tao is a little less confident.

"You can't go wrong with trying." Liu Pengcheng said that he understood, "However, the case is currently confidential, and we must pay attention to the fact that the information cannot be leaked." ”

"Don't worry about this!" Zhang Tao immediately made a guarantee.

Liu Pengcheng gave his computer to Achai before, according to Liu Pengcheng's original plan, even if the new system does not have face recognition, it may not be useless. If Achai and the others were to startle the snake and Liu drove away, the system would at least ensure that the license plate was recognized. Of course, Liu Pengcheng still believes in the technical strength of Xiao Zhai and others, after all, this technology has been used in foreign countries, how can it be learned in a year.

"Okay, then I need your help," Liu Pengcheng was not polite, and the matter was important. The reason why he didn't contact Zhang Tao in advance was that he felt that this case must be kept secret, and the fewer people who knew about it, the better, and the shorter the time he knew, the better.

This system is a fool's operation on Liu Pengcheng's computer, of course Achai can learn it, and soon, several people worked together, and the system began to operate normally.

Villa areas, each of which is a new community. As a high-end community, these places are also the first communities to install cameras, so Achai and others can get the monitoring of all communities, but special measures must be taken, and the security guards of the community cannot know that someone is checking the monitoring, so as to ensure that nothing goes wrong.

The monitoring rooms of this era are all locked, because they are afraid of being stolen, after all, whether it is a display screen or monitoring equipment, it is not a cheap thing. The monitoring equipment is not a common computer chassis + screen in later generations, but a large black box with a bunch of wires inserted on it, each camera corresponds to a line, the security guard can't understand this thing at all, and will unlock it when needed.

Although these devices are relatively new, they are all low-end products, the speed of query and monitoring is very slow, and the transmission speed is also slow.

After thinking about it, this plan doesn't work at all, and Achai and the others have the ability to sneak in and copy the video, but it's too slow! As for removing the hard drive, the nature of this matter may change. To put it seriously, if there is a murder here tonight, and the police did not take pictures of it because the police secretly dismantled the hard drive, how much responsibility can this be?

Liu Pengcheng gave a new plan, not to check the villa monitoring, but to check the city's largest and most high-end shopping mall monitoring.

Going to the villa area to check the surveillance may surprise the snake, but the shopping mall is not. No matter how powerful Liu is, it is impossible to spend money to ask the people in the shopping mall to report to him, and it is impossible for the people in the shopping mall to know what the police are checking and monitoring for.

Liu pays great attention to the quality of life, daily consumption is lavish, gold and silver are soft and easy to buy, according to the time, he has been in Guicheng for more than a year, and he has long been at ease, and it is not difficult to check his trajectory in other places.

Not only large shopping malls, but also some high-end clubs can also be checked. In short, no one knows which case the police are going to investigate.

The three of them had relevant documents, acted separately, and by four o'clock in the morning, they had already copied a large number of videos back, and then connected to the system for face recognition.

Face recognition is only part of the work, and the three of them are still playing at double speed on the computer to distinguish Liu's situation with the naked eye.

At 6 o'clock in the morning, it was dawn, Liu Pengcheng did not rest, Achai and others did not rest, the system was still running, at this time, the system did not find Liu's voice, but Achai's colleagues did.

Liu is really in Guishi! And I've really been in and out of a certain mall recently! Less than 1 km away from this big shopping mall, there is a villa area called Lijiang Garden!

As soon as he saw this name, Liu Pengcheng immediately seemed to remember something, yes, yes, it's called this name, it's Lijiang Garden!
