Chapter 546 Black technology?
"Lost?"
"We sent seven vehicles and more than 20 people to follow you. Now, you tell me that you lost us!?"
Inside the Metropolitan Police Department, the director held the phone, veins bulging on his forehead as he questioned word by word. His deep voice was like the repression of a volcano before it erupted.
"Yes, yes..."
The captain who was in charge of following the team had cold sweat on his forehead, and the subordinates beside him were all silent.
If nothing unexpected happens, they will then face a storm of attacks from the director.
Ten minutes later...
The captain scratched his dizzy ears, feeling a little hallucinatory, as if the director's scolding was still echoing in his mind.
His subordinates were shouting loudly, and he finally came to his senses and asked, "Ah, what did you say? Speak louder."
"Still chasing?"
"Of course we have to chase them. Now, at this moment, everyone, set off. As long as they are still in Taiji Town, we must find them all, even if we have to dig three feet deep!"
Unlike the furious Metropolitan Police Commissioner, Richard and the others all had happy expressions on their faces. The depression they had felt for many days had dissipated and they were in a much better mood.
"What should we do next?" Mandy asked Bifang excitedly, holding the headset.
"Get off as soon as possible, at the next stop. Also, let me tell you one more thing, never discuss sensitive information in an unknown environment. Contact me after you get off the stop." After instructing Mandy, Bifang stopped talking.
Mandy nodded and confirmed the information with the people around her.
Whether it is a tram or a bus, each has a fixed route. As long as someone is careful and does a quick check, they can understand the route of Richard and others. Therefore, they must leave before the followers set up defense at the next stop.
Bifang stood on the hillside and looked at the road below.
This is right in front of Dolphin Bay. Dolphin Bay is surrounded by mountains on three sides. The sea water spreads over the beach, and further up, there is a high wall.
Above the high wall is a wide road with low hills on both sides, so the road leads to tunnels at both ends.
Dolphin Bay is a lowland with a sidewalk next to the road. Next to the sidewalk is a beach leading to Dolphin Bay. It can only be reached by walking down the stairs, like an ancient city wall.
Bifang wanted to set up several camera points directly above the road, with a wide field of view and looking down from a high place. There was no better observation point than there, but the only problem was.
Due to the tunnel, there are surveillance cameras at both ends. If you want to go to Dolphin Bay Beach, you must cross the road and will inevitably be exposed to surveillance.
Nowadays, surveillance cameras have been installed throughout the streets and alleys of major cities. Traffic stations, ATM machines, jewelry stores, fast food restaurants and other street shops can all capture images of passers-by's faces.
Thanks to cheap monitoring equipment, they can now be spotted even in remote areas of the world.
Japan's surveillance coverage is far less than that of China. Although Taiji Town is not a big city, there may be surveillance cameras on some important roads, and the possibility of damage is very small.
This is no longer a question of the open or the hidden side. No matter who does this, it will appear very abnormal.
Several high-definition cameras are placed in the most sensitive places of Taiji Town residents.
What do you want to do?
What is your purpose in installing these? Who instructed you? What is your motive? Have you obtained permission from the relevant authorities?
Did you get permission to post this? Who is behind you? What do you want to do by posting this? What do you want to subvert or destroy?
Can't answer that?
Don't say we arrested you blindly. We have reasons and evidence. In Japan, we can detain you for the full 28 days without any evidence!
Ahem…
Bifang pressed down his cap and collected his thoughts.
Unfortunately, these surveillances are indeed troublesome, but they are not a problem for Bifang.
To be on the safe side, Bifang often assumes that he has stepped into the range of surveillance cameras and uses some covert or interfering means to reduce the possibility of being discovered.
A baseball cap and a mask are enough.
When you go out, you should avoid wearing masks or adopting strange disguises.
A Bad Hollywood-style disguise will quickly draw attention to you from third parties.
What is truly brilliant is often the simplest; a hat or a hood is enough.
Bifang squatted on the hillside, watching the vehicles appear in the tunnel and then quickly drive into another entrance.
This place is sparsely populated, and Bifang soon found an opening. He turned on the flashlight, and while there were no vehicles passing by, he jumped down from a mountain five or six meters high. After landing, he quickly shook off the fallen leaves on his body, and held the flashlight to shine on the surveillance camera on the roadside.
Many cameras with auto-exposure features will automatically stop down their aperture in bright light - pointing a flashlight or LED light directly at the lens can effectively depigment your photo.
Bifang had gone over the overall plan when he was on the mountain, calculated the action time accurately, and made sure that the sun would always be behind him when he encountered the camera .
Taking advantage of the blurred camera, Bifang quickly ran to the edge of the road, pulled out the telescopic ladder, and came right under the surveillance camera.
He pulled out the razor blade that was pressed against his tongue and quickly inserted it into the rubber sheath behind the monitor, twisting it left and right to pass through the braided shielding and touch the hard metal core.
The core signal of the surveillance camera is transmitted by a common copper conductor, which is wrapped in a sheath made of metal and rubber.
A steel blade touching a copper conductor can create a short circuit, temporarily interrupting video transmission.
Inserting a blade through the rubber sheath behind the monitor, passing through the braided shielding layer and touching the hard metal core, which is the aluminum foil shielding layer, will cause static interference to the monitor and interrupt the image transmission.
It's also very easy to return to normal.
Unplug the blade and the signal will return to normal.
Steel blades are very easy to find. Even the most ordinary guest rooms will have razor blades. If not, go buy some. A box only costs a few dollars.
Such road surveillance must be supervised by someone, and if they find anything wrong, they will definitely come to check it out.
But Bifang didn't want him to come and check. Once the surveillance was broken, no one would come to repair it within a few days. What he wanted was to make the other party unaware that there was a problem.
Five minutes.
Bifang leaves time for himself.
From the time the surveillance personnel discovered it to the time the monitoring had problems, to the time they called to inquire and put it on record, this was probably the time point.
If the staff neglects their duties, this time may be even longer, but Bifang will not rely on such luck.
As long as he completes the goal within this time point, everything he does will not arouse anyone's suspicion.
Following the same method, after interfering with the static electricity of the surveillance camera at another tunnel entrance, Bifang quickly took out the "stone" from his backpack and placed it under the road railing.
It's pretty unremarkable here.
Facing Dolphin Bay, you can take photos as much as you want. Everything everyone does here will be recorded without any omissions.
At this moment, the sound of a car roaring was heard again in the tunnel. Bifang quickly climbed over the railing, put his hands on the edge of the sidewalk, and hung himself on the high wall only by the strength of his fingers.
After the car ran across the road and gradually disappeared, Bifang stepped on the front, took advantage of the brief suspension to quickly grab the railing, climbed up again, and arranged the other stones.
These are small stones and are inconspicuous, but due to their size, they cannot accommodate large batteries, so the power is limited.
Similar to installing concealed equipment, there are terms such as "hard installation" and "soft installation".
The former uses parasitic power from a power source such as a TV or electrical outlet to temporarily load the device.
The latter can be as simple as placing the device inside a tissue box.
A "hard install" requires spending a significant amount of time on the target, but never requires having to dive back in to repair the equipment.
Once the device battery runs out or the storage space is insufficient, sometimes the person who arranged the device may need to take the risk of coming back to deal with the "soft installation" device.
As for which method to choose, a conclusion can only be drawn after weighing multiple factors such as available locations, monitoring duration, and achievable sound quality.
Although it is possible to create a usable monitoring device with just a cell phone and a pair of headphones, the results will be poor if the installation location is poor.
After finishing the above arrangements, Bifang jumped onto the beach, quickly dug a hole, and buried a "boulder" in it, with only a small corner sticking out. It looked like a normal rock with one corner exposed.
Bifang was then covered with some dry fine sand to prevent people from noticing that it had been dug.
Time passes by every second.
Bifang moved very quickly, pulling out the second monitored blade just as the five-minute alarm rang.
In a room, the densely packed surveillance cameras made people dizzy. The two screens that were originally covered with snow returned to normal, and the car drove by without any abnormality.
The staff member who was about to call for repair and inspection was about to press the button, but when he saw this situation, he put down the receiver and registration hand and picked up the phone again.
Everything is as usual.
Bifang in the forest clapped his hands and breathed a sigh of relief. The most difficult part had been solved by him, and the rest would be easy.
But there is a problem.
Bifang flipped through the backpack without the "stone" and said, "There's no equipment left."
The size of the backpack is limited. It can only hold three "boulders", some small stones, and some branches. If there are more, it will be difficult to carry and it will also be inconvenient to move in the forest.
Previously, I worked in three groups with Mandy, Keke, and I. We could carry four or five large boxes at a time. Three trips back and forth meant more than a dozen large boxes, and the work progressed very quickly in one night.
But if Bifang is alone, he can only carry a backpack and cannot go back to get equipment.
Climbing the wall of a hotel during the day would be too conspicuous and easy to be remembered. There are more surveillance cameras in the city and it is impossible for everyone to be stabbed with blades. Bifang must try his best to avoid intersection with Richard and others in front of the public eye.
“I have to make some myself.”
Bifang held the map, and there were still many places he had not visited.
Just as I was thinking about a solution, Mandy called again.
"We got off the bus, now what?"
Bifang hesitated for a moment and asked tentatively: "Play?"
"Are you kidding me?"
"But this is the only way." Bifang was helpless. He could command Mandy and the others to follow him, but he was not a god and could not make them completely transparent in broad daylight.
With such a large group of foreigners, the police can quickly search for Richard and others again through surveillance, unless they break up into small groups and reduce their whereabouts.
But this goes against the original intention of Richard and others to come out to attract attention, and Bifang is also unable to guide everyone.
It is enough for the tree to vent its power once.
"After they establish their power, they will come to take revenge on you. Now I think you should make some weapons." Bifang said calmly.
The prestige has been established, but Richard and others still remember vividly the experience of their first visit to Japan. The other party might get angry and rush up to beat them up.
"arms?"
“You guys have a lot of cameras around, right?”
"nonsense."
Don't forget what they are here for, how could they not have a camera?
"Then you can try to convert the camera into a Taser."
"A Taser? What's that?"
"A stun gun."
Facing Mandy, a layman, Bifang used a simple and easy-to-understand word.
"Camera... stun gun? Are these two words polysemous?"
Mandy stared blankly at the camera on the seat next to her, picked it up and looked at it for a long time, then took a few photos of the station.
Yeah, clear and nice looking.
"How do we modify this thing?" Richard and Jarrett, the two older guys, found it even more difficult to understand. They took the camera and felt it was very hot.
Camera converted into stun gun.
What black technology?
"Don't worry about it. Just do as I say." Bifang waved his hand and walked back to the street. Now he was going to the supermarket to buy some things.
Whether you are an ordinary person or an agent, it is crucial to choose non-lethal methods to defend yourself.
However, it is not easy to buy ready-made Tasers, let alone for Richard and others. Even if they go to buy one, no one else will sell it to them.
It’s actually not difficult to convert a camera into a Taser.
By simply rewiring the device, the electricity that originally powered the flashlight could be directed to the two raised screws, creating a charge that would be enough to temporarily paralyze an attacker.
An opponent who is struck will likely fall to the ground and be incapacitated within a few minutes.
Electric currents of 120 to 380 volts can travel through tissues and nerves, generating static electricity in the body that interferes with communication between the brain and muscles.
The result is impaired motor function and involuntary muscle contraction, making it a powerful non-lethal form of self-defense.
Mond's hands trembled when he heard this.
Photography and taking photos are inseparable. As a photography assistant, Mond never thought that the tool in his hands would be so difficult to handle.
"Now, you listen to me, remove the capacitor of the camera, and then remove the battery."
Film SLR cameras are ridiculously expensive, but when it comes to your life, it's all worth it.
After all, we only have one life.
Bifang began to teach step by step the knowledge that ordinary people could never know.
The first step is to empty the capacitor.
Before disassembling the camera, remove the battery and press the flash button to drain any power stored in the capacitor to prevent accidental electric shock during assembly.
If the capacitors are not discharged correctly, the risk of injury is very high.
Step 2: Disassemble the camera.
Remove the camera casing, remove the circuit board, flash, film, and disassemble the flash unit and circuit board.
"Do you have a screwdriver or wire strippers? Small pliers would also be fine."
"have!"
The electrical expert opened his tool box and took out the tools inside.
After Bifang's reminder, he also knew what to do.
As an electrical expert, he felt that converting a camera into a Taser was a path he had never imagined before.
Many times, it’s not that people don’t know how to do it, but they lack inspiration. If they have not received some training that ordinary people don’t know about, it would be impossible for them to think of this method.
With Bifang's reminder, the electrical expert quickly understood the point and left a small section of film according to Bifang's instructions.
He carefully stripped the insulation off the ends of the wires and wrapped the ends of the wires around the top of the screws . He screwed the screws into the camera housing from the film canister.
Next, wrap the other end of the wire around the capacitor's terminal and secure it with electrical tape.
In this way, the camera's current will flow from the battery to the two screws. As long as you stab them at the enemy, you can achieve the same effect as a stun gun.
The final step is to reassemble the camera, restore the circuit board, and tuck the wires around the circuit board.
“A safety mechanism is also needed.”
"I see."
The electrical expert immediately understood why Bifang had asked him to cut a piece of film. He inserted the cut film between the battery and the battery terminal, thus preventing the modified camera from accidentally discharging.
Finally, I put the outer shell back on, and the overall look is exactly the same as before!
But the inside is completely different. No one would have thought that the "camera" in a tourist's hand is actually a Taser gun that can easily knock people out!
"Bifang! You're a fucking genius!" the electrical expert shouted.
"To use it, drive the screw into your opponent's flesh in a stabbing motion. The impact will cause a significant vibration, which will cause an electrical discharge, but if the device fails to discharge, piercing the skin should cause enough damage to your attacker to allow you to escape."
"This thing is very dangerous." Bifang warned with a serious expression.
If it wasn't for the purpose of preventing accidents from happening to Richard and others, he would never have taught such things.
A simple Taser is far more dangerous than it looks, as the discharge can cause severe shock that can leave a person incapacitated!
