Chapter 159: Signal interference

"Damn it."" Lin Rui cursed secretly. This school, which looks dilapidated in appearance, is actually a high-security zone full of electronic surveillance.
In this situation, Lin Rui didn't choose to rush forward, but curled up to one side, avoiding the surveillance cameras, hiding in a blind spot. In desperation, he could only turn on the communicator, "It's me, what's the problem with you?" Zhao Jianfei's voice whispered in the headset.

I’ve entered the school’s basketball court. Damn it’s everywhere here with surveillance equipment. Automatic surveillance cameras with enhanced night vision functions are available at almost every corner of the intersection. I don’t know if there is a dedicated person on duty or an automatic alarm. Anyway. Each of them is enough for me. I can't move forward now, and I can't stay here for long." Lin Rui whispered, "I need help."
"Use your battlefield recorder to transmit the appearance of those things to me. Maybe I can find the source of this thing." Jiang An said slowly.
Lin Rui used the camera on the helmet to take pictures of the surveillance equipment, and then transmitted them to Jiang An. After receiving it, Jiang An immediately began to search based on the appearance of these monitoring equipment. After a few minutes, he whispered, "I found out. These are dfj-6 monitoring and warning devices. They are produced by a professional security and defense equipment company. Designed and manufactured by a French factory. It is an unattended model that can automatically recognize images and issue a buzzer alarm."
Lin Rui smiled bitterly, "Can you tell me the point?"
"The point is that as long as you are photographed by the camera, it will compare the results of the instant shooting with the original photos taken under no one. Then an alarm will be issued to remind someone of an invasion. Then a large number of rebels and secret society members will Surround you all round." Jiang An said slowly.
"I really thank you for your professional advice." Lin Rui said helplessly, "Is there any other way?"
"There is a way," Jiang An said slowly, "The most feared thing for all wireless transmission electronic devices is electromagnetic interference."
"You mean, I can interfere with these monitoring equipment?" Lin Rui frowned, "What should I do?"
Jiang Jian said in a low voice, "You should be carrying another communicator."
"The other one, do you mean the one Vitak gave to me?" Lin Rui frowned. "Then a modified wireless walkie-talkie can only use a few channels, which is of no use."
Jiang Jian said in a low voice, "Yes, but this modified wireless walkie-talkie has a great transmit power. Once you press the call button, the walkie-talkie is in the signal transmission state, and the signal emitted by this thing is enough to interfere with your neighborhood. All electronic equipment. Especially this kind of monitoring and alarm devices, they use advanced cloud storage, and video signals must be uploaded to the network in time. Avoid the inconvenience of using other storage media."
"I'm not a technical house, can you understand it more easily?" Lin Rui smiled bitterly.
"Simply speaking, these things are stored through the wireless network. The video signal captured by the camera has a transmission process, but this also just gives you an opportunity. If you use the Vitac communicator in a certain range, you can Interfere with the video signal transmission of the monitoring device.
"You mean I can safely pass through this area by pressing Vitalk's broken walkie-talkie?" Lin Rui said in a daze, "It's that simple?"
"It's as simple as that. The old-fashioned walkie-talkie of Vitak is not just a product of the former Soviet Union purchased from where it is bought. It is clumsy and has a lot of power. It does not consider electromagnetic radiation accuracy. After he got it, he further modified it, stunned It’s to increase the transmission power again. It’s the rhythm of using wireless walkie-talkies as satellite phones. But sometimes, you have to admire the creativity of these black guys. They have no intention of creating in the process of extremely digging the distance of walkie-talkies. A simple and practical wireless signal jamming device has been developed." Jiang An couldn't help but smile. "Maybe you can try."
Lin Rui took out the brick-sized wireless walkie-talkie from her body, and reluctantly pressed the call button. Then, there was a screaming noise from his headset, and the communication signal between him and Jiang An had been severely interrupted. He turned his head again and found that the original monitoring devices were still rotating regularly, but now they all seem to have failed. The indicator lights above are constantly jumping, not the red when the alarm is in, nor the green when it is safe. But a yellow indicator light is flashing crazily.
Obviously, these cameras have lost the link and are in a downtime.
Lin Rui couldn't help smiling wryly, "This is really a high-tech encounter with a native method."
Of course he didn't dare to delay too much, and immediately ran along the road, opened a door of the small building next to him, and hid in. After breathing for a while, he couldn't help but slapped a spirit, because this room seemed to be an abandoned old classroom, it was in a mess and there was a smell of mold.
Lin Rui shook his head in confusion, it shouldn't be here. He took out the building plan and looked at it. It should be the old school buildings and classrooms, but they were abandoned later. It seems that the front teaching building and the factory next to the teaching building are the most likely places. But to go there, you must pass through an open area. The bright searchlights almost illuminated the clearing.
If he wants to pass there, he is simply looking for death. If you can't pass it head-on, you must go back and forth to achieve your goal. However, Lin Rui observed the situation through the window and scratched his head again. Because no matter which side you go around, it is not an easy task. Both sides are close to the fence, and under the fence are fully armed secret society members on guard. It can be seen that they attach great importance to the safety of teaching buildings and factories.
The guards are tight and there are many sentries.
Even when passing patrols, they must exchange passwords. Not sloppy at all. These members of the secret society are indeed not comparable to the rebels of General Dunby. Lin Rui hid on one side and took a peek for a few minutes, only to find a few well hidden secret whistles. He felt a little tight, and secretly said a fluke. If he hadn't had an idea just now, he had avoided this old abandoned house first, and then carefully observed the neighborhood from inside.
He has probably been discovered by now. Because those secret whistles are cleverly concealed, they are hiding in unobtrusive places, but their sight is very good. If he rushed over rashly just now, then there are only two results waiting for him, either being shot or captured alive.
Now it seems that his temporary decision to avoid entering this abandoned building is a wise move.
