If you want to know whether there is any car passing by at that time period, you can know it by comparing the surveillance video of the gate facing out.
Qu Mingjun said, "It's impossible, we've already looked at the surveillance video once on the 2nd day, there wasn't a single car."
Mu Zi had already tuned the surveillance video to the same time.
"... There was no wind." Mu Zi looked at the computer, a light flashed in her clear eyes.
"It can't be." Qu Mingjun brought the computer over to look at it.
It was really like this. At the same time, the wind was calm on the highway, even the yellowish weeds on the roadside were motionless, while dust was raised at the edge of the highway.
What does this tell us?
"The video ... is fake?" Qu Mingjun didn't expect this result and was a bit confused, "Then ... which one is fake? Is it the one with the gate facing outward, or the one facing inward?"
"Maybe both are fake, neither video is from the day of November 2nd." Mu Zi decisively said, "Go, let's go back to the factory."
"Ah ... ah ah?" Qu Mingjun was a bit flustered, "Go for what?"
If the video was really fake, then the murderer was probably inside the factory!
Boy ... that's a serial killer!
Qu Mingjun was a bit scared.
"Go to copy the video." Mu Zi said, "Take the surveillance video in the office and make a copy of all of them."
...
The two of them returned to the factory again, much to the surprise of the security guard, "Why are you guys back again?"
Qu Ming Jun smiled and explained, "The file I just copied was copied wrongly, so I turned around and came back, please."
The security guard was a bit impatient, picking up the key to open the office door again, frowning and urging, "You guys hurry up, I'm off work here, I've just met someone to play cards."
"Okay, it won't take 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, it's usually a tough job, right?"
The little girl was pretty and spoke softly, very pleasing.
The security guard was a bit more pleasant and said, "It's okay, this work is free, but it's just a bit boring, as you can see, you may not be able to see a person here all day long, sometimes it's not easy to find someone to talk to."
"That is indeed boring." Mu Zi nodded in agreement and asked, "Are you the only security guard? There's still company if there's two of you."
"There's one more person, the two of us alternate." The security uncle said, skimming his lips, "It's even more boring with him, that's a boring pot."
Mu Zi silently memorized it in her heart.
The amount of video to be copied was too large, the security guard waited for a while and urged them again.
Qu Ming Jun immediately took out a few bills from his wallet and stuffed them into the security guard's hand.
"Delayed your time playing cards, really sorry ... We are also helping the leader to do things, there is no way to deliver these things without bringing them back."
"Hey, understand understand, all are working for people ..." The security guard collected the money, and no longer cared about them, wandering out.
Usually, the factory's surveillance video will be saved for one to two months, and overdue videos are automatically cleared on a regular basis.
This factory's video has accumulated for nearly two months, fortunately, the disk U storage space that Qu Ming Jun brought with him is sufficient and can be copied in its entirety, however, such a large amount of files makes Xiao Ming balk.
"When does this have to be seen, to be able to watch it all ah ..."
The video is divided into one section every two hours, 24 hours a day, there are 12 videos, and the amount of two months ... more than seven hundred videos!
"The fake video from November 2nd must be a reuse of a 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 in the afternoon every day, the weather, the light, and the wind direction won't be the same every day, and we will always find out what's subtly different."
