Retracing the Police Path 1993

Chapter 645: Handling the case overnight

Achai was not very shocked. He looked at Liu Pengcheng carefully, then nodded and agreed to the matter.

Although he didn't know whether Liu Pengcheng's plan was right or not, in fact, there were too many things that Achai could do with a 1% probability, and sometimes the handling of a case relied on piecing it together one by one.

Moreover, Liu Pengcheng actually knew Liu's alias, which Achai had not thought of before. He was sure that Liu Pengcheng must know something else, but he was not going to ask because the tacit understanding was there.

After Achai hung up the phone on Liu Pengcheng, he took a plane that afternoon and landed at Liangjiang Airport. There were two people traveling with him, both of whom looked very ordinary. No one would look at him twice when walking on the street. A few glances. Before leaving, Liu Pengcheng gave Achai a box containing his computer, which might come in handy.

In 2001, Guicheng was still an emerging tourist city. The construction of high-rise buildings on Zhongshan Road had just begun, and there was nothing in the suburbs. At this time, Cross Street-Cultural Palace is a major construction site, and Xionghu Villa is also very popular. Foreign tourists come to visit it.

Achai and others had their own information channels. Before arriving, they had already mastered the three largest emerging villa areas in Guangxi Province. They started investigating after landing on the same day, checking the sales, living and renting conditions of the villa areas in the name of buying a house.

It was already night, and a simple check found nothing. Achai knew that there might be an action in Daoxian County tomorrow, but he speculated that the action had nothing to do with Liu, because in Liu's eyes, this kind of thing was purely a trivial matter, and the people over there were The manpower is still sufficient, but the place where the strength is now empty is Qingxi. Of course, Liu Pengcheng's presence in Qingxi is reassuring.

Liu Pengcheng was sitting in his office, lost in thought.

He held a new map of Gui City in his hand and thought about it. He had no idea which community Liu was in, but he just remembered that he was in a certain villa. Judging from the development of Guangxi City, villas are an emerging product, and there are not many villas that can already be lived in. In other words, the carpet search is very simple, and Achai and others can complete it as soon as tonight.

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

He only knew that Liu had lived in the villa in Guicheng for four years. During this period, he had no idea whether he left or where he went. These details were completely unknown to him. Relying on Achai and others alone is not only difficult, but also risky. At this time, the power of the picture detective still needs to be used.

"Liu Bureau? What's going on?" Zhang Tao was a little surprised because it was getting late.

"There is something very important that I need your help with, but I have to ask first, at what stage of development is your Eagle Eye system now?"

The last time he worked on a case with Director Li and others, Liu Pengcheng proposed several development directions at the case summary meeting. The first is about monitoring quantity 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.

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

"Which step are you asking about?" Zhang Tao respected Liu Pengcheng very much.

"Can face recognition be used in practical applications?"

"It is now version 3.3. The face recognition technology is still in the experimental stage, and the accuracy cannot be guaranteed." Zhang Tao was a little unconfident.

"There's nothing wrong with trying." Liu Pengcheng said he understood, "However, the case is currently confidential, so we must be careful not to leak the information." "Don't worry about this!" Zhang Tao immediately assured.

Liu Pengcheng had given his computer to Achai before. According to Liu Pengcheng's original plan, even if the new system did not have facial recognition, it would not necessarily be useless. If Liu drove away after Achai and others alerted him, this system could at least guarantee the recognition of the license plate. 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, and it can be learned in one year.

"Okay, then I need your help," Liu Pengcheng said without politeness. This is a serious matter. The reason why he did not contact Zhang Tao in advance was that he felt that the case must be kept secret. The fewer people who knew about it, the better, and the shorter the time they knew about it, the better.

This system was a fool's errand to operate on Liu Pengcheng's computer. Of course Achai could learn it. Soon, several people worked together and the system began to operate normally.

Each of the villa areas is a new community. As high-end communities, these places were also the first to install cameras. Therefore, Achai and others can obtain surveillance of all communities, but special measures must be taken to prevent security guards from knowing that someone is checking the surveillance to ensure nothing goes wrong.

Monitoring rooms in this era are all locked for fear of being stolen. After all, neither the display screen nor the monitoring equipment is cheap. The surveillance equipment is not the common computer case + screen in later generations, but a big black box with a bunch of wires plugged into it. Each camera corresponds to a wire. The security guard cannot understand this thing at all, and will only open the door and take a look when necessary. .

Although these devices are relatively new, they are all low-end products. The query and monitoring speed is very slow, and the transmission speed is also slow. Even if you enter through normal channels and want to take away the relevant video content, the copy speed is worrying.

After thinking about it, this plan is not feasible at all. Achai and others have the ability to sneak in and copy the video, but it is too slow! As for removing the hard drive, this matter may change its nature. To put it more seriously, if a murder occurred here tonight, and the police secretly removed the hard drive without taking any pictures, how much responsibility would this have?

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

Going to the villa area to check the surveillance system may alert the enemy, but it is impossible to do so in the shopping mall. No matter how powerful Liu was, there was no way he could pay people in the shopping mall to tip him off, and it was impossible for people in the shopping mall to know why the police were conducting surveillance.

Liu attaches great importance to the quality of life and spends a lot of money in daily life. He buys gold and silver at will. Judging from the time, he has been in Guicheng for more than a year and has long since settled down. It is not difficult to check his trajectory in other places.

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

The three of them all had relevant documents and acted separately. By around 4 a.m., they had copied a large number of videos back and then connected them to the system for face recognition.

Facial recognition is only part of the job. The three of them are still using computers to play at double speed to distinguish Liu's situation with the naked eye.

At 6 o'clock in the morning, it was dawn. Liu Pengcheng didn't take a rest, nor did Achai and others. The system was still running. At this time, the system did not detect Liu's voice, but Achai's colleagues did.

Liu is really in Gui City! And I actually visited a certain shopping mall recently! Less than 1 km away from this large shopping mall, there is a villa area called Lijiang Garden!

When he saw this name, Liu Pengcheng immediately seemed to remember something, yes, yes, that's the name, Lijiang Garden!
