Section Chief Xu didn't hear it, went around behind the computer desk, squatted on the ground, and checked whether the interface between the main chassis B and the ** recording video conversion card and the communication line was loose. Pen ~ fun ~ pavilion www.biquge.info

Lin Xiaohu still has some understanding of the technology of the camera and the camera system, and when he saw him checking there, he ignored him, pulled over a chair by himself, minimized the camera program, and then went to "my computer" to find the surveillance video on hard disks.

Lin Xiaohu has learned a little bit from the two black pictures, it seems that the person who started is not a reckless man, he has carefully observed the security system of the supermarket before starting, and knows that if he does it at the side door of the main entrance of the supermarket, it will be filmed and recorded by the camera, so he destroyed the two outdoor cameras in advance, as for whether the two cameras were directly damaged or only the power cord or communication cable was unplugged, just look at the two cameras later. This shows that the person who started the operation understands the monitoring system, and even if he himself does not understand it, there must be people among the accomplices around him who know. Lin Xiaohu thought that what he was about to face was not an ordinary supermarket owner who was just venting his anger for jealousy, but a criminal gang with intelligence and premeditation.

Lin Xiaohu found the folder where the surveillance video was stored in the D disk of the computer, opened the folder, sorted by the time the file was generated, and found the closest video file to today, which was generated three days ago. I opened the camcorder program and looked at the settings, and the settings in it were saved to generate a video file every 500 megabytes. That is to say, if the amount of data recorded in one day is not enough for 500, then continue to record, it may take another three days, or it may be ten days, in short, it is enough to make up 500 megabytes to generate a separate video preservation file. It seems that if you want to watch last night's video, you have to look it up from this file that was generated three days ago. Although Lin Xiaohu also believes that nothing should be recorded.

But it's a pity,This file can't be opened at all.,The playback software prompts:The file has been corrupted.,Can't open or play.,Try again after the poem is repaired!

Seeing this, Lin Xiaohu was completely cold, not to mention that the scene of the attacker smashing the doors and windows last night was not recorded, and people didn't give them a chance to turn on the surveillance video at all. The possible reason is that the other party destroyed the power supply system or communication line of the two outdoor cameras, and the recording program could not obtain effective recording data, resulting in internal errors in the program, so an incomplete video file was generated in a hurry. If the file is incomplete, of course, it cannot be opened and played.

Section Chief Xu had already checked all the video card interfaces behind the host, stood up and said stunned: "It's all plugged in well, how can there be no signal?" Lin Xiaohu said: "It's very simple, because those two cameras have been destroyed in advance, how can you get the correct picture here?" Section Chief Xu opened his mouth wide in disbelief and said, "Won't it?" Those two cameras are fine, they haven't been smashed. I just took a look at it. ”

Lin Xiaohu smiled and said, "Who said that destroying the camera system will smash the camera?" It is enough for those who know how to break the line or the communication line. Lao Xu, you, the chief of the security section, are not qualified, and you usually need to learn more surveillance and recording technology. Section Chief Xu said with a simple smile, and said, "Don't say it, I really haven't touched this thing before, and I will definitely study hard in the future." ”

Lin Xiaohu asked him to find an aluminum alloy ladder from the warehouse, and then the two of them carried the ladder out. At this time, the owner of the roller shutter door had already arrived with his guys, and first removed the roller shutter door at the main entrance, and some staff opened the broken door to clean up the glass fragments on the ground. So wait for us to go

When you go outside, you can walk out directly through the door and no longer have to climb the window.

Seeing that the supermarket did not call the police, they began to clean up the doors and windows and the mess on the ground, and there was nothing lively to see, so they slowly dispersed. Lin Xiaohu asked Section Chief Xu to set up a ladder under the telephone pole and climbed it up. The pole is made of steel pipe, four meters high, and the diameter is thinner and thinner the higher you go. The camera was located more than two meters above it. Lin Xiaohu didn't have to climb to the top of the ladder, he could already see it clearly when he raised his head.

The shotgun camera is housed in a cylindrical enclosure with a glass lens at the front and a ring of L-printed lights on the outer rim to provide illumination at night, otherwise the camera would not be able to capture any scene in the dark. Looking through the front end, there was no sign of damage to the front glass and the camera, and I turned my head to look at the hole behind the cylindrical housing, which was used for power lines and communication cables to enter and exit. Lin Xiaohu glanced at it and gasped, exactly as he guessed before, the power line and communication line were all cut. The knife edge is neat, there are no burrs, and there are no traces of distortion on both sides of the fracture, which is estimated to be cut directly with scissors. The power supply used by the camera is not higher than 25 volts, which is a weak current, and you don't have to worry about being electrocuted directly with scissors. Lin Xiaohu looked at the camera at the side door, needless to say, that one must have received the same treatment as this one.

Lin Xiaohu climbed down from the ladder, and Section Chief Xu came over flatteringly and said, "Do you want all our security guards to be on duty at the supermarket tonight?" Lin Xiaohu glanced at him. Section Chief Xu said again: "As long as someone is there, no one dares to be so rampant." Lin Xiaohu said, "No need." Xu Ke grew up strange and asked, "What if someone makes trouble tonight?" Lin Xiaohu said: "No. Section Chief Xu asked, "Why?"

Lin Xiaohu didn't speak again, and saw that Guo Maomao was talking to Honghong, so he walked over. It turned out that Guo Maomao was instructing Honghong to ask the supermarket staff to quickly hang up a banner with a seven-to-five discount and hang it high at the front entrance, so that everyone knew that the supermarket was not only closed today, but also played a more favorable discount.

Guo Maomao saw him coming over and asked, "What were you doing climbing the ladder just now?" What did you find?"

Lin Xiaohu said: "The grandson who started it is a master, and he cut the power cords and communication cables of the two only cameras outside before he started." Guo Maomao raised his eyebrows and said, "Then what?"

Lin Xiaohu said: "Then? Their crimes will not be captured by the cameras, and we will not be caught with any evidence. Guo Maomao said: "Then what should I do about this?"

Lin Xiaohu saw Honghong looking at him worriedly, smiled, and said, "Don't worry, with me here, can you still let them mess around?" I've already called my two bodyguards to come over, and we're going to carry out the arrest plan from today. Let me know who did this, and he will die. ”

When Li Bing and Wang Baoqiang rushed over, they were just in time for lunch. After Lin Xiaohu took them to lunch, he took them around the supermarket twice and briefly talked about the situation. At this time, all the roller shutters have been removed, and all the glass shavings have been cleaned up, and the supermarket is bustling with business, and the customer flow is not much different from yesterday. It looks like it's another harvest day. If you only look at the hot business scene inside the supermarket, no one would have thought that this place has just experienced a smash.

Lin Xiaohu took Li Wang and the others to an empty warehouse inside the supermarket, where they were

(This chapter is not finished, please turn the page)

A relatively simple "case analysis meeting" was conducted. The three of them are not policemen, but Li Wang is an excellent special soldier and has excellent investigation ability, Lin Xiaohu has always loved criminal investigation, likes to read all kinds of suspense detective movies and novels, and also has the reasoning ability that is not inferior to that of a college student.

In view of the fact that Li and Wang did not know much, and the scene had been cleaned up when they arrived, Lin Xiaohu briefly introduced the situation: "...... Your sister-in-law and her niece have no enemies in the land. I have, but I'm dead and negligible. It can be said that under normal circumstances, no one will attack our new supermarket. The biggest possibility now is unfair business competition. Some people see that our supermarket is hot for three days, and it is so hot that it is not good, and the turnover is more than 100,000 yuan a day, they are red-eyed, jealous, and worried that even their customers have been snatched away by us, so they want to retaliate against us, and make the prestige of the new supermarket to the minimum, and the reputation stinks, so that no one comes to the door. An eldest sister at the scene said that it was the sound of smashing heard at about 11 o'clock to 12 o'clock last night, in addition to the sound of dogs barking, giving blows, and the roar of the engine of the cart. I took a closer look at the roller shutter door that was smashed out of the big hole, and found that there was a row of neat and uniform depressions like tooth marks distributed in the area of impact, of course, much larger than tooth marks, and I initially suspected that the other party used a large forklift such as a bulldozer, and the tooth marks left were the shovel teeth on the shovel. The speculation was also confirmed by the fresh dirt scattered on the parking lot in front of the supermarket, which was probably just driven from a construction site. Of course, it doesn't make any sense for us to ask the other side what kind of machinery they used to break the door and glass. What we have to see from this is that the other party is definitely not alone. I can't figure out how a forklift driver would smash the doors and windows of a supermarket when he has nothing to do, and he may have been hired. That is, there are at least two people on the other side. There is also a very important one, which is worth abandoning, that is, there are people who understand security cameras. Before they shuttled the door, they cut all the power cables and communication cables of the outdoor elephant machine, so that there would be no traces of them on the spot. This shows that the other party has a high IQ and is also very shrewd and cunning, and may have a similar criminal record. ”

Li Bing said: "We can 'treat others in the way of others', didn't he hire someone to drive a forklift and other large machinery over, then we found the east and west intersections of the road where the supermarket is located, and went to the traffic police to check the surveillance video at that time." They also have the courage to break the camera on the supermarket side, and they definitely don't dare to break the camera next to the traffic light. ”

Lin Xiaohu shook his head and said: "This case has not been reported to the police since the beginning, because I want to solve it privately, I want to teach the other party a lesson, and if I call the police, at most I can only make the other party lose some money." This is not the result I wanted. Therefore, it is impossible to go to the traffic police to view the surveillance footage. Also, I'm not going to use the clues we've found to find out who did it. ”

Wang Baoqiang asked curiously: "I didn't call the police, nor did I investigate in private, so how did I find out that grandson?" Lin Xiaohu smiled and said: "The other party smashed our supermarket, but found that we didn't call the police at all, but swallowed our anger and continued to operate, not to mention that the business was better than before, and deliberately made a lower discount to show anti-Hangzhou to the people who started it, so do you think the other party will give up?" Li Bing said: "Boss, what you mean is that the other party may still make a move, let's wait for the rabbit." ”
