"Lost?"

"Seven vehicles were sent to you, and more than 20 people took turns following you. Now, you tell me, you lost track!?"

In the Metropolitan Police Department, the director held the phone, with a tic-tac-toe-shaped vein popping out on his forehead, and asked questions word for word. His deep voice was like the repression of a volcano before it erupted.

"Yes, it is......"

The captain in charge of following was sweating on his forehead, and the subordinates next to him were all silent.

As expected, they will face a storm from the director next.

ten minutes later......

The captain scratched his dazed ears and felt some auditory hallucinations, as if the director's scolding was still echoing in his mind.

His subordinates shouted loudly, and he finally came to his senses and asked, "Ah, what are you talking about? Please speak louder."

"Are you still chasing me?"

"Of course we have to chase them. Now, at this moment, let me go. As long as they are still in Taiji Town, we will find them all. We will dig three feet into the ground to find them!"

Unlike the furious Director of the Metropolitan Police Department, Richard and others all had happy faces. The depression of the past few days had dissipated and they were all in a much better mood.

"What should we do next?" Mandy pressed the headset and asked Bifang excitedly.

"Get off the bus as soon as possible, get off at the next stop, and let me tell you one more thing, never discuss sensitive information in an unknown environment, and contact me after you get off the bus." After instructing Mandy, Bi Fang stopped speaking.

.

Mandy nodded and confirmed this information with the people around her.

Whether it is a tram or a bus, there are fixed routes. As long as a careful person does a little research, he can understand the route of Richard and others. Therefore, you must leave before the followers set up defenses at the next stop.

Bi Fang stood on the hillside and looked at the road below.

This is directly in front of Dolphin Bay. Dolphin Bay is surrounded by mountains on three sides. The seawater spreads to the beach. Going up, there is a high wall.

Above the high wall is a wide road with low hills on both ends of the road, so this road leads to tunnels at both ends.

Dolphin Bay is lowland. There is a sidewalk next to the road, and there is a beach leading to Dolphin Bay next to the sidewalk. You can reach it by walking down stairs, just like an ancient city wall.

Bi Fang wanted to arrange several camera points directly above the road, with a wide field of view. Looking down from high, there is no better observation point. The only problem is.

Due to the tunnel, surveillance cameras are installed at both ends. If you want to go to Dolphin Bay Beach, you must pass through the road and you will inevitably be exposed to surveillance.

Nowadays, surveillance cameras have been spread all over the streets and alleys of major cities, traffic stations, ATM machines, jewelry stores, fast food restaurants and other street shops. In these places, pictures of the faces of passers-by can be collected.

Because surveillance equipment is so cheap, they can now be found even in remote areas of the world.

The monitoring coverage in Japan is far less than that in China. Although Taiji Town is not a big city, some important road sections may be monitored, and the possibility of damage is very small.

This is no longer a matter of the bright side and the dark side. No matter who does this, it will appear very abnormal.

Several high-definition cameras are deployed in the most sensitive places for residents of Taiji Town.

What do you want to do?

What is your purpose for pretending this, who instructs you, what is your motive, and have you obtained permission from the relevant departments?

Does it allow you to post it? Who is behind you? What do you want to do by posting this? What do you want to subvert and destroy?

Can't answer?

Don't say that we are arresting you blindly, we are all justified. In Japan, we can lock you up for 28 days without any evidence!

Ahem...

Bi Fang pressed his peaked cap and recovered his thoughts.

Unfortunately, these monitoring are indeed troublesome, but they are not a problem for Bi Fang.

To be on the safe side, Bi Fang often assumes that he has entered the range of surveillance cameras and uses some concealment or interference methods to reduce the possibility of being discovered.

A cap and a mask are enough.

When going out, you should avoid wearing masks or adopting weird disguises.

Bad Hollywood movie-style disguises can quickly draw third parties' attention to you.

The really smart ones are often the simplest, and a hat or hood is enough.

Bi Fang squatted on the hillside, watching the vehicles appear in the tunnel, and then quickly drove into another passage.

There are few people here. Soon, Bi Fang found a free period. He turned on the flashlight and jumped down from the five or six meter high mountain while no vehicles were passing by. After landing, he quickly patted the fallen leaves off his body.

Holding a flashlight and shining it at the surveillance camera on the roadside.

Many cameras with automatic exposure will automatically shrink the aperture in bright light - pointing a flashlight or LED light directly at the lens can effectively reduce the pixels of the photo.

Bi Fang had already gone through the overall plan when he was on the mountain, calculated the time of action, and ensured that when he met the camera, the sun would always be behind him.

Taking the opportunity to blur the camera, Bi Fang quickly reached for the edge of the road, pulled out the telescopic ladder, and came directly under the surveillance camera.

He took out the razor blade pressed against his tongue, quickly inserted it into the rubber sheath behind the monitor, and twisted it left and right so that it passed through the braided shielding and came into contact with 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.

Contacting a steel blade with a copper conductor can cause a short circuit, temporarily interrupting video transmission.

Insert the blade into the rubber sheath behind the monitor, pass through the braided shielding layer, and come into contact with the hard metal core, which is the aluminum foil shielding layer. This will cause the monitor to generate electrostatic interference and interrupt the picture transmission.

It's very easy to get back 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 in them. If not, go ahead and buy them. You can buy a box for a few dollars.

Such road monitoring must be monitored by someone. If something is wrong, they will definitely come and check.

But Bi Fang didn't want to wait for him to come over to check. Once the monitoring system was broken, no one would come to repair it within a few days. What he wanted was for the other party not to realize that there was a problem.

five minutes.

Bi Fang left time for himself.

This is roughly the time from when surveillance personnel discover problems with surveillance, to when they call to inquire and record the situation.

If the staff neglects their duties, this time can be longer, but Bi Fang will not pin it on such a fluke.

As long as he completes his goal within this time point, everything he has done will not arouse anyone's suspicion.

Following the same pattern, after interfering with static electricity from the surveillance camera coming out of the other tunnel entrance, Bifang quickly took out the "stones" in his backpack and placed them under the road railings.

It's very inconspicuous here.

Facing the Dolphin Bay, you can take photos as much as you like. Everything everyone does here will be recorded and nothing will be missed.

At this moment, the sound of cars roaring came again from the tunnel. Bifang quickly climbed over the railing and lay on the edge of the sidewalk with his hands, hanging on the high wall with only the strength of his fingers.

When the car crossed the road and disappeared, Bifang stepped forward, quickly pulled on the railing with the help of the short suspension, turned over again, and arranged other stones.

These are small stones, inconspicuous, but due to their size, they cannot hold a battery that is too large, so the power is limited.

Similar to installing hidden equipment, there are "hard installation" and "soft installation".

The former uses parasitic power from power sources such as TVs or power sockets to temporarily load it into the device.

The latter can be as simple as placing the device in a tissue box.

A "hard install" takes a lot of time on the target, but never has to dive back into the device again to service it.

And once the device battery runs out or the storage space is insufficient, sometimes the installer may need to take the risk to come back and deal with the "soft installation" device.

As for which method to choose, you can only reach a conclusion after weighing many factors such as the optional location, monitoring duration, and achievable sound quality.

Although you can create a usable monitoring device with just a mobile phone and a pair of headphones, if it is installed in a poor location, the results will be poor.

After arranging the top, Bi Fang jumped onto the beach, quickly dug a hole, and buried a "boulder" in it. Only a small corner was revealed, which looked like a normal rock with a corner exposed.

Bifang then spread some dry fine sand to avoid being seen to have been dug here.

Time passed minute by minute.

Bi Fang moved very quickly and pulled out the second monitored blade, just as the five-minute alarm sounded.

In a certain room, the dense surveillance made people dizzy. The two screens that were originally full of snowflakes returned to normal again, and cars passed by without any abnormality.

The staff member who was about to call for maintenance and inspection was about to press the button. When he saw this situation, he put down the phone and registration hand, and picked up the phone again.

Everything is business as usual.

Bifang in the forest clapped his hands and breathed a long sigh of relief. He had solved the most difficult part, and the rest was easy.

But there's a problem.

Bi Fang rummaged through his backpack with the "stones" missing: "There is no equipment left."

The size of the backpack is limited. It can only hold three "boulders", scattered small stones, and some branches. Any more will be difficult to carry, and it will also be inconvenient to move in the forest.

Previously, I worked in three groups with Mandy and Keke, and we could carry four or five large boxes at a time. We made three trips back and forth, which is more than a dozen large boxes. The work progressed very quickly in one night.

But if Bifang was alone, he would only have a backpack, and he couldn't go back to get equipment.

Going to a hotel to climb the wall during the day is too conspicuous and easy to be remembered. There are more surveillance in the city and it is impossible for everyone to have a blade inserted. Bi Fang must try his best to avoid interacting with Richard and others in front of the public eye.
