Kevin Johnson smiled and said, "Mr. Tang, in fact, this pressure alarm can not only alarm for changes in space pressure, but also for the pressure outside the glass ceiling. ”

Tang Feng looked at Kevin suspiciously. Johnson, who said he didn't know, but seemed to be very conscious.

Kevin. Johnson said: "In fact, if you want to destroy the glass ceiling without maintaining pressure, there are still ways to do it, such as building a sealing layer on the outside of the glass ceiling in advance, so that when the glass is broken, it will not cause a change in pressure." Then, when the glass is broken, the pressure inside and outside is balanced with a very small gap, which will delay a long time, but will not cause the pressure alarm to alarm. Therefore, in response to this possible situation, this pressure alarm has another function, that is, it can monitor the pressure change outside the glass ceiling at all times. ”

Kevin. Johnson pointed to the glass ceiling and said: "Mr. Tang, in fact, our glass ceiling design is very good, for example, the outermost layer of the glass ceiling is paved with two meters of bulletproof glass, which creates a pre-made fact, if you want to destroy any piece of glass, then someone has to step on the glass ceiling to complete such a work." Mr. Tang, this is the conclusion we have come to after hundreds of experiments, because no one can complete the destruction of glass without stepping on it. Of course, you can set up a set of shelves on top of the glass ceiling and people walk over the shelves, but I don't think it's possible to have such a big battle if it was a jewelry thief."

Tang Feng nodded with a smile, Kevin. Johnson is right, those jewelry thieves who want to steal the items in the museum must travel lightly, and if they want to get Kevin. The kind of thing that Johnson is talking about. That's almost impossible.

Kevin. Johnson clicked on another interface and said: "Mr. Tang, in order to prevent this from happening, we have thought of corresponding countermeasures, that is, infrared reflection devices. Inside the glass ceiling, we have placed 32 infrared reflectors that emit multiple beams of infrared rays of a specific wavelength that can penetrate bulletproof glass. The exterior of the glass ceiling is monitored at specific intervals. Because there is a distance limit, so these infrared alarms will not be affected by the fallen leaves, those fallen leaves are too small, but once there are things that should not appear outside the glass ceiling, such as high-strength plastics, metal products, as long as the volume exceeds the infrared separation distance, then the infrared alarm will alarm. With this set of devices and the pressure alarm, the protection of the glass ceiling can be described as leak-proof! ”

Tang Feng tilted his head and thought about it, thinking of himself as a jewelry thief. But after thinking about it for a long time, I couldn't figure out how to break through these damn alarm devices. Because these alarms are all installed inside the building, they are simply indestructible from the outside, which creates an almost impenetrable status quo.

"Yes, yes!" Tang Fengxiang's head hurt a little, so he smiled and agreed.

After looking at the glass zenith, the place where problems are most likely to occur, Tang Feng and their guests in Kevin. Johnson led the way to the first floor, which was completely done. Just waiting for the opening in three days, so whether it's security or whatever. It's all on track.

"Mr. Tang, there are a total of 64 small exhibition halls on the first floor, each of which is equipped with three fixed high-definition cameras, in addition, there are also 32 high-definition spherical cameras installed in the hall, and these cameras exist. It can be a good way to complete the monitoring of the exhibition hall during the day. At night, in addition to these cameras, 32 spherical infrared cameras are installed throughout the museum, and the security personnel on duty every night wear an identification card. As long as the security guards wearing this identification card patrol their respective patrol areas, they will not be alerted by these infrared cameras. However, if the patrol security guard walks out of his patrol area, he will be alerted by the infrared camera, even if he is wearing an identification card. Although this arrangement is very restrictive to security, it can be a good guarantee that once the identification card is obtained by outsiders, it will not be used. Because outsiders have no way of knowing the area where the security guards patrol every night. Similarly, if there is no person wearing an identification card to enter the building at night, it will also cause an infrared camera alarm at the first time. ”

Tang Feng nodded, this kind of security measure can greatly prevent many accidents from happening, and this arrangement is undoubtedly very good. The security of the museum at night is undoubtedly a top priority, and it is worth the hassle to do so.

Kevin. "These bulletproof glass boxes that protect the exhibits are made with the most advanced technology, which can resist the shock wave generated by the explosion of half a kilogram of T.N.T. equivalent explosives, and can also prevent 0.50 caliber bullets from firing at close range," Johnson said, pointing to bulletproof glass boxes in a small exhibition hall. At the same time, there are audio alarms installed inside the glass box, because the bulletproof glass is also glass, which may be shattered by sound waves, and the audio frequency set by these audio alarms is the same frequency as the audio that can resonate with the bulletproof glass, so as long as this sound wave frequency appears, the alarm will automatically alarm. ”

After a pause, Kevin. Johnson continued: "There are pressure alarms in the glass boxes, and once the glass box is broken or the pressure in the glass box fluctuates, then the exhibits will automatically sink into the safe within one meter of the ground within 0.1 seconds, which is also to prevent anyone from attacking the glass box during the day and stealing the exhibits with the help of the panic of the crowd. With this automatic safety device, the possibility of the exhibits being stolen is minimized. ”

In addition, the entire museum's security system and power system are divided into three separate systems, one of which is directly connected to the monitoring room of the Tang Ranch through underground cables buried deep in the ground, so even if someone destroys the system server in the museum, the system in the ranch can still provide security precautions for the place. In addition, we have quietly installed two sets of high-definition cameras on the two mobile phone signal towers outside the museum, which can monitor the external situation as a whole, and these two cameras are separate systems, unless they know that there is monitoring here, and destroy this place in advance, otherwise, the internal and external monitoring of the entire museum is perfect. ”

Tang Feng is really satisfied this time, you must know that the budget for the security system made for the museum was as high as 20 million US dollars, and now it seems that the absolute value of these 20 million US dollars is spent, with the existence of these security measures, the entire museum can be called a drop of water!
