It’s a very easy job to guard the big Ivan, because there is nothing to do, and then monitoring the big Ivan is definitely a chore, because it will be very boring.

It’s easy and boring, but it’s also a responsibility, so it’s definitely a good place to be sent to the outskirts of Cape Town to guard the big Ivan.

It is estimated that the task of guarding the big Ivan will finally fall to the head of the CIA. After all, the CIA has the most experience in doing this kind of thing.

If the CIA is guarding the big Ivan, then Yang Yi is much easier, why is it easy, because he knows how the CIA monitors an important goal.

After going to the scene and looking at the local terrain, Yang Yi’s heart will have a spectrum.

"The big Ivan's manor is on the flat, the CIA will erect a pole, and then install a surveillance system, you can sit in the monitoring room to monitor the Ivan's manor, and the most effective monitoring method is long-haul. When there are two drones, as long as there are two, you can do 24 hours of uninterrupted aerial investigation. Hey, for the sake of insurance, there will be at least four drones here."

Pointing at the sky, Yang Yi whispered: "In the high altitude that we can't distinguish with the naked eye, there must be a small drone in the recreation. Anyone coming in and out will be discovered, and then the video will be recorded. The only inconvenience is that the image is black and white. Because black and white images have smaller digital signals and are faster to transmit, they can be monitored in real time."

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

Yang Yi nodded: "Yes, basically this is the case."

Gleevav beats the hand: "This is a bit of a hassle. I didn't expect the CIA to monitor it with drones."

Yang Yi shrugged and smiled. "Wait, I have a way."

Yang Yi took out a mobile phone.

"Mobile?"

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

Yang Yi played with it for a while, then he began to try to enter the password, saying: "The existence of these drones means that the signal can be transmitted in real time, then the drone needs to transmit the signal to the ground, and I have permission. 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 position while receiving the signal."

Grevatov said: "There is no explanation for the principle."

"Ok."

Yang Yi did not intend to say it, but he couldn't help it, so he finally said: "My receiving terminal is transformed, don't forget that we have the best hackers."

"Hackers are hackers. Modifying hardware devices is not really a good thing for hackers."

"Hey, we have hackers who are familiar with the hardware, so I can receive the signal, but don't worry about exposing myself, etc... well!"

Yang Yi took the phone to Grevatov and looked at it. Then he smiled. "Yes, we have a drone on our head."

The drone is not big, but it doesn't need to be big, because modern sighting and detection equipment can do very little, but it is powerful.

"There is still a night vision mode..."

Grevatov felt a little embarrassed because on the mobile phone of Yang Yi, the large Ivan's manor was clearly displayed, and included a large open space around the building.

Yang Yi laughed: "First of all, this drone has no thermal imaging mode, maybe a thermal imaging instrument, but it will certainly not open, because the drone's oil can support flying in the air for twelve hours, but thermal imaging. The battery can't be used for 12 hours, so if there is thermal imaging on the drone, there will only be three working modes, which will be turned on and off periodically, or automatically after detecting the heat source. The last one is found by the controller. Manually open after an exception."

Grevatov said: "Automatic opening is impossible, so the second option and the first one should be the same, that is, thermal imaging is automatically turned on and off."

"A correct answer, automatically open every other time, scan it, and then focus on the heat source after the heat source is discovered, but here is South Africa, there are many wild animals on the outskirts of Cape Town, and Da Yiwan is only under house arrest, this is Monitoring, rather than finding the target, fires, so there is only one possibility that thermal imaging will not always be used, but after the suspicious target is found, the drone controller is manually turned on."

"What do you mean by saying so much?"

Yang Yi put her hand down and smiled. "Nothing, just want to say that it is easy to solve. Hey, let's go."

Gleevav followed Yang Yi to go forward and walk, they need to go a long way.

"Can you control the drone?"

Yang Yi nodded and said: "Yes."

Grevatov sighed and said, "Why don't you say it earlier?"

"Oh, I want to say that you interrupted."

Gleevov raised his hand: "Wait a minute, why you can control this drone, even if there are a lot of equipment inside the CIA that is universal, but a task should be independent password, or any other technical means to stop casually. Can one control his own device?"

Yang Yi shrugged and said: "Hey, I have the highest authority. I have a back door. I can take over most of the control of the equipment. I want people to discover it and let people discover that if I don't want to be discovered, then no one will. I can't find it."

“Why is this?”

Yang Yi sighed and said: "Because a person who appreciates me very much, okay, so I have the authority to be owned by the deputy director of the free CIA, which is commonly known as the back door dog."

"What is the relationship between the back door and the dog?"

"It doesn't matter, just a joke."

Gleevav suddenly frowned: "Wait, you just said that the hackers of the water organization have modified your receiver? But now I don't think it is ~lightnovelpub.net~ Of course not, Yang Yi simply does not need others to transform What, Aaron left his legacy is not just a few words, as Yang Yi said, he now has a part of the authority of the CIA deputy director, Aaron gave.

"Hey, you know it, you don't have to say it."

Yang Yi stopped his foot and said: "It is time to go to the scope of the investigation of the drone."

Gleevav looked at Yang Yidao: "How are you going to solve it?"

Yang Yi smiled and said: "It's very easy. If the drone loses its control signal, it will fly back automatically. When the person inside solves the problem, or directly releases the second drone, we have already entered."

Grevatov sighed and said: "I admit, I originally wanted to see what you have, but I did not expect you to be the CIA's back door."

Yang Yi frowned and said: "Hey, you learn really fast..."
