“？！ - "Everyone was dumbfounded when they heard this.

Putting surveillance equipment in the chief's room? The people at the hotel are crazy. Or are the people in Lingxi Province crazy? Even if you are very happy with the arrival of the chief, and want to record the words and deeds of the chief in detail for later admiration, you will not install surveillance equipment in the room, right?

Could it be that you even want to know a thing or two about the chief's habit of taking a bath, changing clothes and going to the toilet?!

This is obviously ill-intentioned, not only the faces of the main leaders of Lingxi Province have changed greatly, Fan Heng's expression is also very bad, as for the person in charge of the hotel, he has been stupid at all, he can't tell how his crime should be determined, should it be classified as an intention 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 can a good five-star hotel be equipped with monitoring equipment?

"I'll take a look—" Fan Wuxian asked his father, Fan Heng, to stay outside, and then followed the guards into the room.

Fan Wuxi was also very curious about the installation of monitoring equipment in the hotel room, in his mind, people in Lingxi Province would not be so brain-dead, right? What are the benefits of doing this? Could it be that someone really wants to spy on the leader's personal **? The stakes are a little too great.

The Yuhe Hotel has a floor height of 21 floors, which can be regarded as the first luxury hotel in Lingxi Province. It's just that because Ningshi, the provincial capital of Lingxi Province, lacks a similar reception place for public servants, the frequency of use here is very high, which leads to the fact that cadres below the deputy department level are not qualified to live in it at all.

Even if you live in, you have to divide it into three, six, nine and so on according to the administrative level.

Generally speaking, the bottom three floors are the renovated venue, restaurant and activity hall, the parking lot is on the two underground floors, the fourth to the twelfth floor, are for cadres at or above the deputy department level, the thirteenth to sixteenth floors are for cadres at or above the deputy department level, as for the seventeenth to eighteenth floors this is for the provincial deputy provincial cadres, the nineteenth and twentieth floors are dedicated to receiving important officials of the central government, and the twenty-first floor is a special place for leading cadres at or above the deputy department level to hold meetings. It was also held on the 21st floor.

This is why Ye Nan's jump that day was from the window on the twelfth floor, this is because his husband Wu Shengyong is Pang Mingyu's secretary, and the level is deputy director, but he has the advantage of being around the leader, so he can pick a floor with the best location, and the room he came to book is naturally impossible in the name of Pang Mingyu, so the highest is on the twelfth floor.

Fan Heng's room is on the nineteenth floor, and although the twentieth floor is also used to entertain the central leaders, under normal circumstances, when the central leaders are staying in, there are no people here, mainly to ensure that no one walks on the top of the leaders' heads, which will not affect their rest. Otherwise, as soon as the chief here fell asleep, there was a sound of high-heeled shoes above his head, wouldn't that be ruined?

Fan Heng's guards are all master bodyguards at the central level, not only fists and feet, but also proficient in various means of investigation and counter-investigation, usually always have to receive regular training and exercise of the latest technology, so as soon as he entered the house, he used the electronic equipment he carried with him to detect it, and immediately found that there was a problem inside, and he immediately found the problem as soon as he surveyed the signal source, and immediately found the problem, which turned out to be in the bedroom, living room and bathroom, a total of seven miniature camera probes were installed, And I also found a wireless transmitter installed behind the TV to borrow the hotel's power supply.

"Mr. Fan, you see, it's this kind of thing-" Fan Heng's guards are still used to calling Fan Wuxian President Fan, and if you say that calling him Fan Advisor, it is indeed a little uncomfortable.

"Yankee's product—" Fan Wuxi looked at the pinhole camera that came out, and immediately found the logo on it.

The principle of various pinhole cameras is similar, they project the light collected through the lens on the image sensor, which converts the light signal into an electrical signal. The electrical signal is converted into a digital signal, which is compressed and transmitted to a monitor or recording device to display or record an image that can be seen.

Due to the limitation of size, this type of camera generally does not have too complex functions, can not adjust the focal length, can not adjust the aperture size, they are generally composed of lens, image sensor, analog-to-digital converter, image controller and other parts, if with audio function, but also add sound collection, processing and transmission components.

The pinhole camera that Fan saw was about the same size as the lens he later used on his mobile phone, using a fisheye lens.

The so-called fisheye lens is a short-focal length ultra-wide-angle lens, which has a lens arc that is very close to a spherical surface, and the angle of view can be close to or even 180 degrees, and the shooting range is much larger than other lenses, which can cover more scenes.

However, the expansion of the shooting range comes at the cost of the distortion of the subject, and the object captured with the fisheye lens is very distorted, which can only ensure that the scene in the center of the picture remains unchanged, and other horizontal or vertical scenes will be distorted and look unrealistic.

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

Generally speaking, fisheye lenses are generally used when shooting scenes with a large range, but if you want to save costs, you should use a flat lens to get better shooting results. There are many cases where conical lenses are used.

Wireless cameras will send data outward, and the transmission range can reach tens or even hundreds of meters, as long as the receiver is installed in this range, the video signal can be collected. Wired cameras, on the other hand, 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 needs a power supply, detect whether there is a small lens that can reflect on the wall, ceiling, chandelier, furniture, and even tissue boxes and vases, dim the light, can make the pinhole camera unable to get a clear image, turn off the power of the room, and also make the pinhole camera unable to work, the general security personnel will use special detection tools to scan the signal emitted by the wireless pinhole camera, and accurately locate it.

Fan Heng's guards use a special pinhole camera detection equipment, this equipment can emit infrared visible light to the surface of the object to be detected, if the surface of the object has a spherical lens similar to a pinhole camera, from the position of the professional eyepiece on the equipment can clearly see the pinhole position of the pinhole camera, to achieve the purpose of discovery.

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

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

"It's not like the work of a professional. It's rough to install, and the wires are crappy. The guard replied.

Fan Wuxian nodded and said, "Since it is wireless, then there will definitely be a receiver nearby, try to find it, and then see what is going on." ”

Generally speaking, the location of the receiver is definitely not too far, and the people on the hotel side, give them two the guts, and they don't dare to do such a big rebellious thing, since the guard said that it is not like a professional to do it. Then it's likely that someone who has access to these rooms did it.

Fan Wuxi directly thought of some possibilities, such as someone who could enter the hotel room to clean? But this is unlikely, because all the work in the hotel is done by internal personnel, so there are some other groups of people left, such as plumbers, but it doesn't look like it from the line, so he called a hotel executive and asked, "Has this floor been overhauled or something recently?" ”

"Overhaul?" The people in the hotel were frightened now, and after thinking for a while, they said, "By the way, the carpet was replaced once last month because it was a long time, and it seems that there was no more before that." ”

Fan Wuxi glanced at the guard, and immediately thought that there must be a problem here, because judging from the installation of the camera, it was a matter of a month, so he asked again, "Is it possible that the person who replaced the carpet still has access to here?" ”

"Yes, it's usually our staff who clean it, but they come once a month to clean it thoroughly." The hotel man replied.

Fan Wuxi discussed with the guards for a while, and then said to the officials of Lingxi Province who were nervously following behind him, "Well, it's best to let the technical experts from the Provincial Public Security Department come over, extract fingerprints or something, and then immediately go and control all the people who replaced the carpet to see if they did it." ”

At this time, the officials of Lingxi Province were most concerned about whether they could get rid of this injustice, and at this time, hearing that Fan Wuxi was arranging work here, someone immediately called and notified the technical experts of the Provincial Police Department to rush over, and said to Fan Heng with some trepidation that this incident was really accidental, and it was definitely not made by Lingxi Province.

Fan Heng hasn't expressed his position yet, in fact, he is also very disgusted by this matter, originally he came to Lingxi this time because he had a lot of work to correct for them, but he didn't expect that a camera could be installed in his room, which is really infuriating. That is, he has a good cultivation now, so he did not have a seizure on the spot, but his face was expressionless, which made several leaders of Lingxi Province feel uneasy.

Within ten minutes, the technical experts of the Provincial Police Department rushed over, and everyone was frightened when such a big incident happened.

There are no pop-ups
