If you want to know if there are any cars passing by during that time period, you only need to compare the surveillance video with the gate facing outward.

Qu Mingjun said: "Impossible, we have already seen the surveillance video on the day of the 2nd, and there is not a single car." ”

Mu Zi had already adjusted the video to the same time.

“…… There was no wind. Mu Zi looked at the computer, and a glimmer of light flashed in her clear eyes.

"Impossible." Qu Mingjun took the computer and looked at it.

That's true. At the same time, the road was so calm that even the yellow weeds on the side of the road did not move, while dust rose on the edge of the road.

What does this mean?

Video ...... Is it fake? Qu Mingjun didn't expect this to be the result, and was a little confused, "That's ...... Which one is fake? Is the gate facing outwards or inward? ”

"Maybe it's all fake, neither of the two videos is from the day of November 2nd." Mu Zi said decisively, "Let's go, let's go back to the factory." ”

"Ah...... Huh? Qu Mingjun was a little flustered, "What are you going to do?" ”

If the video is true or fake, then the murderer is likely to be in the factory!

Obedient...... That's a serial murderer!

Qu Mingjun was a little afraid.

"Go copy the video." Mu Zidao, "Make a copy of all the surveillance footage in the office." ”

……

The two returned to the factory again, much to the surprise of the security guard, "Why are you back again?" ”

Qu Mingjun explained with a smile: "The file I copied just now was copied by mistake, so I turned around and came back, and I trouble you." ”

The security guard was a little impatient, picked up the key and opened the office door again, frowning and urging: "Hurry up, I'm off work, and I just made an appointment to play cards." ”

"Okay, it won't be too long." Qu Mingjun tried to smile as kindly as possible.

Mu Zi said to the security guard: "Uncle, such a big factory needs to be taken care of, and it usually works very hard, right?" ”

The little girl is beautiful, soft-spoken, and very pleasing.

The security guard was a little more pleasant, and replied: "It's okay, this work is leisurely, but it's a little boring, you can also see, you may not be able to see a person here all day long, and sometimes it's not easy to talk to someone." ”

"That's really stuffy." Mu Zi nodded in agreement and asked, "Are you the only security guard?" If you have two people, you can still have a companion. ”

"There's another person, and we're going to take turns." The security guard said, pouting, "It's even more boring to have him, it's a stuffy jar." ”

Mu Zi silently remembered it in her heart.

The amount of video to be copied was too large, and the security guard waited for a while and urged them again.

Qu Mingjun immediately took out a few banknotes from his wallet and stuffed them into the hands of the security guard.

"I'm sorry to delay your time to play cards...... We are also helping the leaders to do things, and we can't do it without bringing these things back. ”

"Hey, I understand, I understand, it's all for people...... "The security guard took the money, stopped caring about them, and went out in a hurry.

Typically, the factory's surveillance video is stored for one to two months, and the overdue video is automatically cleared at regular intervals.

The video of this factory has accumulated for nearly two months, fortunately, the disk U storage space brought by Qu Mingjun is sufficient, and it can be copied completely, but such a large amount of files makes Xiao Ming worried.

"I have to see when this is going to be done, and then I can finish it......"

The video is divided into one session every two hours, and there are 12 videos in 24 hours a day, and the amount of two months is ...... More than 700 videos!

"The fake video on November 2 must be a reuse of the previous video." Mu Zi's eyes narrowed slightly, like a shrewd little fox, "This video was recorded in the evening, we only need to check the video from four to six o'clock in the afternoon every day, the weather, light, and wind direction will not be the same every day, and we will always find subtle differences." ”
