Chapter 835 Chaos

"?!——" Everyone was dumbfounded after hearing this.

Install surveillance equipment in long rooms? The people at the hotel are crazy. Or are the people in Lingxi Province crazy? Even if you are very happy about the arrival of the elder and want to record the elder's words and deeds for later viewing, you wouldn't install monitoring equipment in the room, right?

Could it be said that you even want to know something about Chang's habit of taking a shower, changing clothes and going to the toilet? !

This was obviously done with ulterior motives. Not only did the main leaders of Lingxi Province change their expressions, Fan Heng's expression was also very bad. As for the person in charge of the hotel, he was completely frightened and he could no longer tell the difference. How should I determine this crime? Should it be classified as an attempt to steal state secrets, or a conspiracy to endanger the safety of national leaders?

Anyway, no matter which one it is, you can't eat it and walk around, that's for sure. The question is, how could a five-star hotel be equipped with surveillance equipment?

"Let me take a look -" Fan Wubing asked his father Fan Heng to stay outside, and then he followed the security personnel into the room.

Fan Wubing was also very curious about the installation of surveillance equipment in hotel rooms. He thought, people in Lingxi Province wouldn't be so stupid, right? What are the benefits of doing this? Could it be that someone really wants to spy on the leader's personal identity? The risk of doing this is simply too great.

The floor height of Yuhe Hotel is twenty-one, making it the first luxury hotel in Lingxi Province. It's just that Ning City, the provincial capital of Lingxi Province, lacks similar reception venues for public servants, so the frequency of use here is very high. This means that cadres below the deputy director level are not eligible to live here at all.

Even if you move in, you will be divided into three, six or nine levels according to the administrative level.

Generally speaking, the lower three floors are the renovated conference venue, restaurant and event hall, and the parking lot is on the second underground floor. The fourth to twelfth floors are all prepared for cadres at the deputy director level and above. The 13th to 12th floors are The 16th floor is reserved for cadres at the deputy department level and above. The 17th to 18th floors are reserved for provincial and deputy provincial cadres. The 19th and 20th floors are reserved for receiving central officials. , a special place for meetings of leading cadres at the deputy department level and above on the 21st floor. Sometimes the speeches given by people from the central government are also held on the 21st floor.

This is why Ye Nan jumped out of the window on the twelfth floor that day. This is because his husband Wu Shengyong was Pang Mingyu’s secretary, with the rank of deputy director, but he occupied the position next to the leader. The advantage is that he can choose a floor with the best location. The room he booked cannot be in the name of Pang Mingyu, so the highest one is on the twelfth floor.

Fan Heng's room is on the 19th floor. Although the 20th floor is also used to entertain central leaders, usually when there are central leaders staying,

No one is allowed here, mainly to ensure that no one is walking over the heads of the elders and will not affect their rest. Otherwise, as soon as my son fell asleep, the thump of high heels could be heard above his head. Wouldn't that be destructive?

Fan Heng's security personnel are all master bodyguards at the central level. Not only are they skilled in boxing and kicking, they are also proficient in various investigation and counter-investigation methods. They always receive regular training and training on the latest techniques. Therefore, as soon as they enter the house, I checked it with the electronic equipment I carried with me and immediately discovered that there was a problem inside. I followed the signal source and immediately discovered the problem. It turned out that there were a total of seven micro cameras installed in the bedroom, living room and bathroom. Probe, and also found a wireless signal transmitter installed behind the TV that borrowed the hotel's power supply.

"Mr. Fan, look, this is the kind of thing -" Fan Heng's guards are still used to calling Fan Wubing "Mr. Fan". If they call him "Counselor Fan", it is indeed a bit uncomfortable to call him.

"It's a product of the Yankees -" Fan Wubing looked at the protruded ** and immediately saw the logo on it.

The principles of various pinhole cameras are similar. They cast the light collected through the lens on the photosensitive element, and the photosensitive element converts the optical signal into an electrical signal. The electrical signal is converted into a digital signal, and the digital signal is compressed and transmitted to a monitor or recording device, so that it can be displayed or recorded into a visible image.

Due to volume limitations, this type of camera generally does not have overly complex functions and cannot adjust the focus or aperture. They are generally composed of lenses, image sensors, analog-to-digital converters, image controllers and other parts. If equipped with For audio functions, components for sound collection, processing and transmission are also added.

The pinhole camera that Fan Wubing saw used a lens similar in size to the lens later used on mobile phones, using a fisheye lens.

The so-called fisheye lens is a short focal length wide-angle lens. Its lens curvature is very large and close to the spherical surface. The viewing angle can be close to or even reach 180 degrees. The shooting range is much larger than other lenses and can cover more scenes.

However, the expansion of the shooting range comes at the expense of the distortion of the subject. The object captured with the fisheye lens is very deformed. It can only ensure that the scenery in the center of the picture remains unchanged. Other horizontal or vertical scenery will be distorted and look very strange. Untrue.

In addition to fisheye lenses, there are also flat lenses and conical lenses. Conical lenses can restore images better, but the cost is much higher than spherical lenses. They can only be used when there are relatively high requirements for image quality. Only conical lenses will be used.

Generally speaking, fisheye lenses are generally used when shooting scenes with a large range. If it is from the perspective of cost saving, then use flat lenses. To obtain better shooting effects. Conical lenses are often used.

Wireless cameras will send out data, and the range of the transmission can reach tens of meters or even hundreds of meters. As long as the receiver is installed within this range, the video signal can be collected. Wired cameras must be connected to a data cable to work, and the other end of the data cable is often connected to the recording device.

In addition, any pinhole camera requires power. Detecting whether there are small reflective lenses on the walls, ceilings, chandeliers, furniture, and even tissue boxes and vases, dimming the lights can prevent the pinhole camera from obtaining a clear image. Turning off the power of the room can also prevent the pinhole camera from working. Generally, security personnel will use special detection tools to scan the signal emitted by the ** and accurately locate it.

Fan Heng's guards use a special ** detection device, which can emit infrared visible light to the surface of the object to be detected. If there is a spherical lens similar to ** on the surface of the object, the position of the ** pinhole can be clearly seen from the professional eyepiece position on the equipment, achieving the purpose of detection.

Because of this, they were able to find seven cameras in the hotel rooms in such a short time.

"Who do you think did this?" Fan Wubing asked.

"It doesn't look like the work of a professional. The installation is rather crude, and the wiring is rather poor." The guard replied.

Fan Wubing nodded and said, "Since it is wireless, there must be a receiver nearby. Try to find it and see what's going on."

Generally speaking, the location of the receiver must not be too far away. The people in the hotel would not dare to do such a rebellious thing even if they had the courage. Since the guard said it didn't look like it was done by a professional. Then it is very likely that someone who can access these rooms did it.

Fan Wubing immediately thought of some possibilities, such as someone who can enter the hotel room to clean it? But this is unlikely, because all the work of the hotel is done by internal staff, so there are some other groups left, such as plumbers, but judging from the wiring, it doesn't seem like it, so he called a hotel executive and asked, "Has this floor been inspected recently?"

"Inspection?" The hotel staff were now very scared, and thought for a while before saying, "By the way, the carpet was replaced once last month because it was old, but it seemed that it hadn't been replaced before."

Fan Wubing looked at the guard and immediately thought that there must be a problem here, because judging from the installation of the camera, it was only a matter of a month, so he asked again, "Is it possible for the person who replaced the carpet to come into contact with this place?"

"Yes, it is usually cleaned by our staff, but they come to clean it thoroughly once a month." The hotel staff replied.

Fan Wubing discussed with the guards, and then said to the Lingxi officials who were nervously following behind him, "Well, it's best to let the technical experts from the Provincial Public Security Department come over to extract fingerprints and so on, and then immediately control all the people who changed the carpet to see if they did it."

At this time, the officials of Lingxi Province were most concerned about whether they could clear this unjust accusation. At this time, listening to Fan Wubing arranging work here, someone immediately called to notify the technical experts of the Provincial Police Department to rush over, and at the same time told Fan Heng a little anxiously that this matter was really unexpected and definitely not caused by Lingxi Province.

Fan Heng has not yet expressed his opinion. In fact, he also feels very disgusted with this matter. Originally, he came to Lingxi this time to correct many tasks for them. Unexpectedly, cameras were installed in his own room. This is really infuriating. It was because of his good self-cultivation that he did not do it on the spot, but his face was expressionless, which made several leaders of Lingxi Province feel uneasy.

Within ten minutes, technical experts from the Provincial Police Department arrived. Everyone was scared by such a big incident.
