Smoke experts share the mystery of anti-theft smokers (1)

Anti-theft smog
Expert introduction
Zhang Xiulin, senior engineer, chief expert of Beijing Funitek Security Technology Co., Ltd., has been engaged in chemical weapons and smoke research for many years. A number of technologies have filled the domestic gap and reached the world's advanced level.
After retirement, he joined Beijing Funitek Security Technology Co., Ltd. to develop an anti-theft and anti-smoke device suitable for the security market, which greatly reversed the passive defense situation of the security industry and can easily drive the intruders away from the scene.
In response to some of the problems that recent partners often care about for anti-theft and smoke smugglers, we have put them together so that partners can have a clearer understanding of anti-theft and smog, and they will better play their powerful driving role.
Question 1: Is the smoke emitted by Funi burglar-proof smoker toxic?
Dean Zhang: When it comes to smoking devices, many people will associate the poisonous gas bombs used in warfare. Once inhaled, it will kill people. The smoke machine we developed, the core ji technique is derived from the various smokers of the bu team, but there are differences. The various types of smoke bombs used by the bu team zuo warfare have nearly 20 types from their basic distribution ratios, and with changes in shape and structure, hundreds of products will be derived. We conduct comprehensive evaluation and screening on the stability, toxicity and easy operation of these products, select several matching methods of Zuijia, and then further improve the civilian demand, and completely replace some toxic components. Drop, so that the generated smoke will not cause harm to the human body. The smoke has been tested by the national authority Bu door and is completely non-toxic.
Question 2: Does the Finnish smoker use cold smoke, does it mean that the smoke is cold?
Dean Zhang: When it comes to this cold smoke, it will be easy for people to confuse with the humidifier and the fog machine used on the stage or bonsai, thinking that the smoke from the smoker is also cool. There is still a certain difference between this. The cold-smoke technology we mentioned refers to the process in which the Fini smoker does not smoke by consuming oxygen, which in turn produces smoke. That is to say, the solid materials we use are completely smoked by our own reaction, and do not depend on the oxygen in the air. This is different from the way we cook and smoke, and we need oxygen to burn firewood. To be extreme, when it is smoked, it will continue to smoke even if it is placed in the water. Of course, the temperature at which the smoke is emitted is not high, and the heat is much lower than the fire from the firewood or the stove, and does not cause a fire.
Question 3: Since the cold smoke technology is used, the surface of the smoker is also the same as the room temperature?
Dean Zhang: This should be emphasized. The smoker has just been sprayed, and it must not be touched by hand. It is easy to burn. Through our actual test, the temperature of the smoker is close to 500 °C just after the smoke is sprayed. Therefore, when installing, be sure to pay attention to the inability to have flammable and explosive materials around, as well as some shells and related electronic equipment that are easily deformed at high temperatures.
Question 4: Can the smoker be integrated with the camera?
Dean Zhang: Integrating the camera and the smoker is our special product. The smoker and the camera are placed in different chambers to avoid the camera due to the high temperature of 500 °C. Damaged. Generally, the melting point of solder is between 180 and 300 ° C. After the aerosol is sprayed, the solder of the circuit board is basically in the open state. As a component on the circuit board, its working range zui high will not exceed 80 ° C, and the image sensor of the camera Zui core - CMOS is more delicate, after the smoke is finished, the electronic components around the smoker are basically nothing left. . Therefore, despite the requirements of the partners, we have to order a small, highly integrated camera with a smoke-emitting function. Zui is still the popular panoramic camera. It is strongly recommended that the two devices be installed separately as zui , and the smoke machine can be replaced after the spray is finished, and the camera can not be turned into a dice.
Question 5: Are there any strict requirements for the installation and installation methods of the smoker?
Dean Zhang: The smoker is not suitable for any occasion.
First of all, the outdoor is absolutely unacceptable, and a gust of wind will quickly dissipate and will not serve as a deterrent.
Then there is the storage center in the big open space, such as the one of thousands of square meters, we do not recommend installation. Because it is necessary to quickly fill the smoke in a short time, but to achieve the purpose of blocking the line of sight, it is necessary to arrange a large number of smokers, and the construction cost of the project will be relatively high.
For the installation method, we can share our relevant experience of measurement with you:
If ceiling mounting, such as our KM6804A, is recommended, the height should not exceed 2.7 meters. Too high will affect the diffusion of smoke. There are many drawbacks to the ceiling installation method (because the height of the roof of each site is different, and it is often more than 3 meters), we have developed a KM6800A-1, which is designed for various indoors. The environment is very convenient to arrange, and it can be installed in various ways such as lifting and wall mounting. And the directionality of the smoke jet can be adjusted at will, and it can be effectively controlled for some key areas, so that once the smoker starts, the key areas will be quickly protected first.
In terms of installation height, according to our practical application experience, it should be low and not high .
This time, we will unify the five issues that everyone is concerned about. After that, we will continue to organize the common concerns and share them with our peers. We hope that all security colleagues can actively contribute to our products. In order to develop products that are closer to the market demand.
