In the past three days, Han Chaoyang has called Wu Wei and Xu Hongliang a lot.

I thought they were visiting and inquiring outside as they had done a few days ago, but when they returned to the gravel yard, they were sitting listlessly outside the work area and smoking.

"Angkor, Hongliang, what are you doing here?"

"Smoking. Xu Hongliang held up the cigarette between his fingers.

"Nonsense, I'm asking why you don't go out to investigate. Han Chaoyang opened the car door and stuffed a change of clothes into the police car first.

"I didn't have to check, I ran all the places I should run, I asked all the questions I should ask, and I found nothing. Wu Wei threw away the cigarette butt and stood up, took out two invoices from his trouser pocket, and said with an embarrassed face: "I'm sorry, the oil ran away from two boxes, if you can report it, you can help me report it, if you can't report it, forget it." ”

"You don't have a bus for private use, why can't you report it?" Han Chaoyang asked rhetorically, took the invoice and said, "How is the task force over there, have they made any progress?"

"It doesn't seem like there is, it shouldn't be. ”

"How do you know?"

Xu Hongliang couldn't help but smile and said: "Because we have often crashed in the past two days, either we have just finished asking them to arrive, or they have just finished asking us to arrive, yesterday afternoon was the most interesting, and they rushed to a small shop that is usually open until two or three o'clock in the morning at almost the same time." If there's progress, they're going to run like this. ”

"Crash" with the task force, and often "crash"!

Han Chaoyang was made to cry and laugh, and asked with a bitter face: "Who did you meet, did they say anything?"

I have never encountered such a funny thing, Xu Hongliang said with a smile: "A criminal policeman surnamed Fang and a criminal policeman surnamed Gao, they are errands like us, not only did they not say anything, but they also had a supper with us." If it weren't for their leaders calling and asking them to go back quickly, we really planned to communicate with them about the case. ”

"They may have thought that our superiors had also given us the task of visiting and questioning. Wu Wei looked up and smiled.

As long as the other party doesn't say anything.

Han Chaoyang didn't want to move a stone to hit himself in the foot, so he breathed a sigh of relief, and asked with a smile: "What should I do next, will I check it next?"

Wu Wei wanted to solve the case, but Wu Wei was not stupid, recalling the experience of the past three days, he sighed helplessly: "If you don't investigate, it's useless to investigate again, at least this line can't be investigated." ”

"How did you get there?"

"How can you ask, isn't it just to ask if you have seen anyone with suspicious deeds, especially those who drive commercial vehicles. In the final analysis, there are still too few clues, I don't know the license plate, I don't know the model, I don't even know the color of the car, there are more commercial vehicles on the road, who knows which car is suspicious. ”

"We even went to the surrounding gas stations to check the surveillance video. Xu Hongliang added in a low voice.

"Since you can't check it, then don't check it. Han Chaoyang patted him on the shoulder, lifted the plastic sheet and walked into the operation area, he didn't know if he didn't look at it, he was suddenly stupid when he saw it, more than 20 migrant workers screened it for three days, and the sand pile seemed to be still so big, and the sand didn't seem to be much less.

"Han Da, you're back!"

"I'm back, I've just arrived, I'll leave it to me here, you pack up and go back early." ”

Han Chaoyang smiled and nodded with Xiaokang and PolyU security guard Xiao Xu, and was about to say hello to the migrant workers who were sifting sand, when he suddenly remembered something and immediately lifted the plastic sheet and walked out of the operation area.

"Hongliang, you drive back the police car later, don't go back to the police office, go directly to the auto repair shop. ”

"What are you doing in the auto repair shop, this car is new, it only runs more than 3,000 kilometers, and it takes 5,000 kilometers to get the first insurance. ”

"Go install the dash cam. Han Chaoyang raised his hand to greet the migrant worker who was smoking outside, and explained: "On the way back from a mission in the field, a traffic accident occurred in the Third Squadron of the Criminal Police. The collision was quite serious, but fortunately there were no major incidents. Now to determine the responsibility, the criminal police driving the car thinks that it is the responsibility of the other party, and the other party says that it is their responsibility, anyway, the public says that the public is reasonable, and the mother says that the mother is reasonable. ”

Wu Wei reacted and subconsciously asked, "One person is sick, and the whole family takes medicine?"

"Almost, the leaders of the bureau think that we should take this as a warning and make up for it, as long as it is the police car of our sub-bureau, all of them must be equipped with tachographs. Speaking of this, Han Chaoyang's eyes lit up, and he stared at Wu Wei and asked, "Angkor, how long can the video taken by the dash cam be saved?"

"It's like a loop shot, shooting a section and covering a section, and it shouldn't be saved for long, maybe only five or six minutes. ”

"You're the old calendar!"

"By the way, you have a dashcam installed in your car, how long can you keep it?" Han Chaoyang shifted his gaze to Xu Hongliang.

"The memory of my dash cam is 16G, which can record for about 240 minutes and then cover it. My memory is not large, which is about the same as a mobile phone, and there are 36G, which can record for a longer time, about 480 minutes, that is, 8 hours. Xu Hongliang paused, and then said: "There are more advanced, my friend just bought a car, which is equipped with a cloud-shared dash cam, with an emergency lock function, and the emergency images that are selected to be saved will not be overwritten even if the memory is full." ”

"Cloud sharing?"

"What cloud computing and cloud storage are popular now, but I only know what clouds, don't ask me what's going on. ”

Han Chaoyang was not interested in what "cloud", but asked eagerly: "Hongliang, what kind of dash cam do current car owners generally choose?"

"There are 8G, 16G and 36G, electronic products are updated quickly, and the memory is not very expensive. ”

"The average person drives for a few hours a day, I mean the average private car owner. ”

"It depends on how far away the home is from the unit, like me, I don't drive much, no more than an hour a day. ”

Wu Wei suddenly realized why Han Chaoyang asked this, stared at the 110 police car that had not yet installed the dash cam, and muttered: "It's not that there are no cameras in Xianzhuang and the surroundings of Xianzhuang, it's just that we didn't expect the cameras installed in the car." ”

Xu Hongliang also understood as if he had been enlightened, and slapped his thigh with a snap: "Chaoyang, why didn't you say it earlier, it's been more than a month and a week, what's the use of saying it now!"

"That's what I just thought. ”

"In hindsight, it's too late! Even if there is a video, it will be covered a long time ago!"

Wu Wei didn't want to let go of even a glimmer of hope, and said categorically: "Not necessarily, if someone doesn't use a car for a few days." ”

"Then we have to hurry up and visit and ask the nearby car owners, especially those who drove the car on the night of the crime. ”

"The traffic monitoring is stored for a long time, we can expand the range, look at the traffic surveillance video around Xianzhuang during the period, first find the motor vehicles that have been driving in the vicinity in the middle of the night, see how many cars are installed with the dashcam, and then find the owner to watch the video recorded by the dashcam. ”

"That's a good idea, can we adjust it?"

Since there is hope and even opportunity, who doesn't want to solve the case!

Han Chaoyang weighed it and said resolutely: "You go to visit and ask, I will report to the Feng Bureau, as long as the Feng Bureau supports it, I will definitely be able to see it." ”

"Okay, that's it!"
