The four groups of new duty systems are still beginning to bear fruit, although there were few people yesterday, but after more reasonable arrangements, Ren Xu and Bai Song both slept at night.

At seven o'clock the next morning, Bai Song got up early and went to the cafeteria to eat, the criminal police and the case handling team were ready to arrest people.

"Yesterday I caught those two thieves, and I was busy until four o'clock in the morning to get people in. Li Yunfeng rubbed his temples: "There is a thief with high blood pressure. ”

"That's really trouble. Bai Song understands that this kind of disease is a bit more cumbersome.

"I've stayed up late every day, my blood pressure is 160, and the thief is only 155, really, alas..."

Bai Song slept at one o'clock yesterday, and the thief's criminal detention procedures had been completed at that time, but he didn't expect to be sent to the detention center for a long time.

"You don't have a break for a while", Bai Song said: "I don't have anything to do today, if you need help, just say it." ”

"The three who worked overtime with me yesterday, I gave them a break, and I couldn't rest. Li said: "Then you can go to that production base with me, but after the meeting at noon yesterday, I asked a few people to go around and take a look, and I felt that there was no great value, and I might have run away." ”

"Then why didn't you go in yesterday?" Bai Song was a little curious.

"It's a small road that isn't very easy to follow, and when you go in through the path, and when you see the building, there's some open space nearby, and if there's someone inside, you'll definitely find it if you go inside. Li used his hand to compare the terrain: "Connected to this path is a road that has fallen into disrepair, but there is surveillance, but the camera can't directly capture the path, we stayed in the vicinity several times, and we didn't see any cars entering or exiting it." ”

"How big is the scope of this video?" Bai Song was a little puzzled.

"It's just the video next to the intersection, and the road is not a formal road, so there are no traffic signs," Li explained: "There are not many cars running on the road connected to the road, and there are some trucks pulling goods passing by every day. ”

"Is there any surveillance, I'll see. Bai Song asked.

"Yes, in my computer, I can watch it in the car for a while, if you don't like the car shaking, you can watch it. Li said: "It's a little long way to go to that place." ”

After taking the computer, in the back seat, Bai Song looked at it directly.

This is a half-month video in total.

Watching the video is really a headache, this is 360 hours of surveillance video, even if you don't pause at all, watch 16 times the speed, you have to watch it for more than 20 hours without blinking, no one can bear it.

"No, it's too much, go to the criminal police, I'll find someone to get it." Bai Song looked at hundreds of video recordings and felt dizzy.

"Okay. "Li Suo is not in a hurry, if he goes to the criminal police now, he can just talk to the second team about arresting people, and it is only half past seven.

It was already eight o'clock when he arrived at the criminal police team, and Bai Song took Li Suo's computer and found Wang Liang first.

"Do you mean, find out all the cars passing by here?" Wang Liang casually opened a video and found that there were big cars passing by on this road basically every few minutes, and the camera shot the angle from the side, and the license plate number could not be seen.

"That's right," says Bai Song, "and what I need to filter is the big cars that are traveling at speeds of less than 20 kilometers per hour. This video can't shoot the small road I want to see, but all the big cars that want to go to that road and get out of that road must be lower than 20 per hour, because the big car has to brake in advance, and the acceleration ability is also very poor, and the blind spot of this monitoring is only more than 20 meters away from that road.

In addition to the big cars that want to go that way, there are also big cars coming out of that road, and the others are all traveling at speeds above 40 per hour. There are very few small cars and pedestrians on this road, and large cars will not easily reduce their speed to below 20. ”

For big cars, speed is money.

If there is a problem, you must slow down, but if you don't have anything to do and slow down and accelerate, a few dollars of gas money will be easily consumed.

"Okay, no problem. Wang Liang understood what Bai Song meant: "It will be done in the afternoon." ”

This is not difficult in computer programs, first of all, the current video processing software, can capture specific GIFs, and the passing of large trucks is specific GIFs, which is very conspicuous. Here you can only grab the GIF the size of a big car, and the small car can be spared.

Suppose that a car with a speed of more than 40 kilometers per hour takes 5 seconds to enter and disappear from this surveillance camera, and a car with a speed of 20 kilometers per hour takes 10 seconds.

It's simple.

Wang Liang directly started to disassemble Li Suo's laptop.

"What are you doing?" Bai Song was startled.

"His computer is too slow, five or six hundred GB of video, even if it is 30 megabytes a second, it is estimated that it will take more than half a day to copy it, and it must be operated by my computer to multi-thread computing from my computer", Wang Liang said: "Remove his hard disk and connect it directly to my computer with an interface to act as a mobile hard disk, so that you can open the video file directly in his hard disk, saving several hours." ”

"Well, just don't break it. Bai Song looked at Wang Liang's skillful technique, I am afraid that he has done a lot of work, and it seems that his skills are becoming more and more proficient.

This kid is good, if he loses his job, it is estimated that he will be able to eat enough to repair the computer... Bai Song muttered a few words and left the house of the third team.

...

The people to be arrested today are not so easy to catch, several of them have a good sense of anti-investigation, and the criminal police have also done a lot of preliminary planning and received some technical support.

Of course, Zhang Che is very easy to catch, he is idle every day, and he can catch it casually...

If you weren't worried that the "second brother" might report to Zhang Che, just ask him where Zhang Che is, and then call him over.

Bai Song didn't go to catch those people, Ren Xu was still making up for sleep in the office, and before 8:30 a.m., Bai Song ran out but it was fine, but Ren Xu couldn't.

After he handed over to Wang Liang here, Li Suo also finished chatting with the captain of the second team, and the two of them took five people from the case-handling team in the institute and drove two cars to the base first.

This place is in the suburbs, and after driving dozens of kilometers of road, the car entered this road.

There is a highway nearby, so this path has basically been deserted, there are very few cars, Li has been here a few times, the car can drive up to forty or fifty at most, and then it can fall apart quickly, and there are some potholes, the car has a bad view, and it is not easy to dodge.
