Chapter 1385 Backdoor Dog

Watching Big Ivan is definitely a very easy job, because there is nothing to do, and watching Big Ivan is definitely a hard job, because it will be really boring.

It's relaxing and boring, and you still have to bear responsibilities, so being thrown to the outskirts of Cape Town to guard Big Ivan is definitely a good place to be assigned.

It is estimated that the task of guarding Big Ivan will ultimately fall on the CIA. After all, the CIA has the most experience in doing this kind of thing.

If the CIA was guarding Big Ivan, then Yang Yi would be much more relaxed. Why would he be so relaxed? Because he knows how the CIA monitors an important target.

After arriving at the scene first and taking a look at the local terrain, Yang Yi had an idea.

"Big Ivan's manor is on flat land. The CIA will erect a pole and install a surveillance system. Then he can sit in the monitoring room and monitor Big Ivan's manor. The most effective surveillance method is the long-distance voyage As long as there are two drones, we can achieve round-the-clock uninterrupted aerial reconnaissance. Well, to be on the safe side, there will be at least four drones here."

Pointing to the sky, Yang Yi said softly: "There must be a small drone flying in the sky where we can't distinguish it with the naked eye. Anyone who comes in or out will be discovered, and it can also record videos. The only inconvenience is that the image is black and white. Because the digital signal of black and white images is smaller and can be transmitted faster, real-time monitoring can be achieved."

Grevatov frowned and said, "You mean we can't go in without being discovered?"

Yang Yi nodded and said, "Yes, that's basically the case."

Grevatov spread his hands and said: "This would be a bit troublesome. I didn't expect the CIA to use drones to monitor it all the time."

Yang Yi shrugged and said with a smile: "Wait, I have a solution."

Yang Yi took out a mobile phone.

"cell phone?"

"No, it's a mobile intelligence receiving terminal...well, it's actually a mobile phone, just disguised as a mobile phone, but its function...well, it's just a mobile phone."

Yang Yi fiddled with it for a while, and then he started to try to enter the password and said: "The purpose of these drones is to transmit signals in real time, right? Then this drone needs to transmit the signal to the ground, and I have the permission." It is received, but as long as I connect the drone, it will leave traces, just like a mobile phone connected to WiFi, it will also reveal its location while receiving the signal."

Grevatov said solemnly: "There is no need to explain the principle."

"OK."

Yang Yi didn't plan to say it at first, but he couldn't help it, so he finally said: "My receiving terminal has been modified. Don't forget that we have the best hackers."

"Hackers are hackers, and modifying hardware devices is actually not what hackers are good at."

"Well, we have hackers who are familiar with the hardware, so I can pick up the signal without worrying about exposing myself, wait... Okay!"

Yang Yi showed the phone to Grivatov, and then he smiled and said: "Yes, there is a drone above us."

The drone is not big, but it does not need to be big, because modern observation and reconnaissance equipment can already be made small but powerful.

"There's also night vision mode..."

Grevatov felt a little embarrassed, because on Yang Yi's mobile phone, Ivan the Great's manor was clearly displayed, and the huge open space around the building was also within the display range.

Yang Yi smiled and said: "First of all, this drone does not have a thermal imaging mode. It may have a thermal imaging instrument, but it will definitely not be used, because the fuel capacity of the drone can support flying in the air for twelve hours, but the thermal imaging However, the battery cannot be used for twelve hours. Therefore, if there is thermal imaging on the drone, there will only be three working modes: scheduled opening and closing, or automatic opening after detecting a heat source. The last one is discovered by the controller. Turn it on manually after an exception."

Grevatov said solemnly: "It is impossible to turn on automatically, so the second option should be the same as the first, which is to automatically turn on and off the thermal imaging."

"Correct answer, it will turn on automatically every once in a while, scan it, and then focus on observing the heat source after discovering it. But this is South Africa. There are many wild animals in the suburbs of Cape Town. Also, Big Ivan is just under house arrest. This is Monitoring rather than firing when a target is discovered, so there is only one possibility. The thermal imaging will not be used all the time, but the drone controller will manually turn it on after a suspicious target is found."

"What do you want to express by saying so much?"

Yang Yi waved his hand and said with a smile: "Nothing, I just want to say that this is easy to solve. Well, let's go."

Grevatov followed Yang Yi and started walking forward. On foot, they had to walk a long way.

"Can you control a drone?"

Yang Yi nodded and said, "Yes."

Grevatov breathed out and said, "Why didn't you tell me earlier?"

"Uh, I'd say you interrupted."

Grevatov raised his hand and said: "Wait a minute, why can you control this drone? Even if there are many devices within the CIA that are common, each mission should have an independent password or other technical means to prevent random One person can control his own device, right?”

Yang Yi shrugged and said: "Well, I have the highest authority, I have a backdoor, and I can take over most of the device control. If I want to be discovered, I can be discovered. If I don't want to be discovered, then no one can." Can’t find it.”

"Why is this happening?"

Yang Yi sighed and said: "Because of a person who appreciates me very much, okay, so I have some permissions that only the deputy director of the free CIA can have, which is also commonly known as a backdoor dog."

“What does the back door have to do with dogs?”

"It's okay, just a joke."

Grevatov suddenly frowned and said, "Wait a minute, you just said that hackers from the Water Organization modified your receiver? But now I don't think so."

Of course not. Yang Yi doesn't need anyone else to modify him at all. The legacy left to him by Aaron is more than just a few words. As Yang Yi said, he now has some of the authority of the deputy director of the CIA. Aaron gave him of.

"Well, you just need to understand, you don't have to say it."

Yang Yi stopped and said: "If you go further, you should be within the detection range of the drone."

Grevatov looked at Yang Yi and said, "How do you plan to solve it?"

Yang Yi smiled and said: "It's very easy. If the drone loses the control signal, it will fly back automatically. By the time the people inside troubleshoot or directly release the second drone, we will have already entered."

Grevatov sighed and said: "I admit, I originally wanted to see what you were capable of, but I didn't expect you to be the CIA's backdoor dog."

Yang Yi frowned and said, "Well, you learn so fast..."
