precisejammers

　　The cell phone jammer is the ideal tool for banning cell phones. In addition, cell phone jammer also allows your child to grow up in a good environment. With the development of smart phones, more and more problems have been brought to people's lives, exposing more security and social problems.

　　In addition, there are many or more personal use shields. A lot of people find it weird why do individuals use cell phone jammers? Why do people need to get those devices that are actually quite expensive? But it's not hard to understand that everyone has the right to protect their privacy and now that phone tracking is so easy, on a cell phone information will inevitably be leaked. Then you need to prepare tools to prevent this from happening. When you're enjoying your precious time in a place where you shouldn't be on the phone, like a movie theater, and someone near you keeps talking on his cell phone, so don't you want to shut him up with a cell phone blocker?

　　A simple example, most schools have installed cell phone jammers. On the one hand, it is to prevent students from playing with mobile phones, and on the other hand, it is to prevent students from using mobile phones and other electronic products to cheat, so that students can develop integrity. habits that are very important to their lives. While internet use of cell phone jammers varies a lot for schools, it doesn't stop at schools, and even without a legally mandated response, schools seem to allow you by default. Schools can use gps jammers to prevent cheating on exams, but they don't fully address situations where students are in class.

　　We've heard or known that cell phone jammers have been around for a long time. The original purpose of the cell phone jammer was mainly for police and military applications. In the military, interceptors are used to block enemy communications. police can use jammers to prevent communications from criminals and prevent terrorist attacks, such as jamming some signal-controlled bombs.

　　Now, jammers are being used for more and more urban purposes. Some organizations, such as schools, use jammers to prevent cheating, companies use jammers to block cell phone use, and some factories use it to protect the confidentiality of information.

　　So, to solve the above problem, a simple and effective way is to use cell phone jammer. It's not hard to see why so many people want to use jamming devices.

　　In recent years, various types of gps jammers have emerged in an endless stream, and we are dazzled and dizzy, but in fact not all products are suitable for us to apply to ourselves. Some products are public, so they are not suitable for being used by us. We apply to other fields, there is a very special gps jammer, which also appears in front of us, its name is cell phone jammer, so what kind of advantages does this type of product have?

　　When we use the cell phone jammer, you will find that no matter where we are, as long as such a jammer can be turned on, then everyone has no way to search for our wireless signal, in other words, household products The effect is more obvious than that of ordinary public products. In such an environment, we can always block all signals easily, but if we use a public blocker, it may appear that the shielding effect is unstable. problem, so we need to understand the specific use effect.

　　The cell phone jammer is mainly used in the examination room, and is not limited to the examination room. It can also be used in prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor camps, conference rooms, theaters, churches, etc. Libraries, school dormitories, special security and confidentiality occasions (confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitaries to guard the scene), etc. will be used.

　　Using high-scatter aluminum alloy shell, the working temperature is low, and the shielding effect is more stable.

　　Separate power adapter. 12V/24V DC power supply work, convenient for vehicle mobile work.

　　The external design of the antenna and the unified interface at one end make the appearance more beautiful and decent. And it has an anti-loosening design, and the antenna and the host have a marked working frequency band for one-to-one correspondence.

　　Relevant departments such as petroleum, chemical industry, and security have expressly stipulated that the use of mobile phones in gas stations is prohibited.

　　The equipment of the gas station is controlled by the computer. The signal of the mobile phone will affect the normal operation of the equipment, resulting in inaccurate measurement. More importantly, the mobile phone will spark during the dialing process, which can easily cause a fire and cause the gas station to explode. Therefore, the gas station that belongs to the fire prevention area is not only strictly forbidden to use mobile phones in the station, but also it is best not to use mobile phones within two or three meters around the gas station.

　　At the same time, gas stations should set up obvious signs prohibiting cell phone calls, and widely publicize safety knowledge, so that people understand that using signal cellphone jammer in gas stations is undoubtedly walking with tigers. There have been many fires caused by the use of mobile phones across the country. In a gas station, the driver used a mobile phone when refueling, which caused an explosion and caused a serious accident that caused many casualties.

　　At present, the mobile phone signal is almost everywhere, and all electrical equipment is surrounded by it. When the mobile phone signal amplifier is not used, the interference of the surrounded signal to other electrical equipment is minimal. This is because there is no data exchange between the mobile phone and the base station when the mobile phone is not used, and it is impossible to form a sudden change. signal, electrical equipment is surrounded by a relatively stable electromagnetic field, that is, a static electromagnetic field, the interference of this static electromagnetic field to electrical equipment is almost zero. Therefore, it is absolutely necessary to use a mobile phone gps jammer in the gas station.When using a mobile phone, there is data exchange between the mobile phone and the base station, and random mutation signals are generated, so that a dynamic electromagnetic field is formed around the electrical equipment. This dynamic electromagnetic field signal will induce mutation interference signals. cause malfunction of electrical equipment. When the cell phone battery starts, when the ringer rings, it can generate enough energy to cause a slight spark that can cause a fire.

　　why is it forbidden to make phone calls at gas stations?

　　As we all know, gas stations dealing with flammable and explosive materials are high-risk industries, and "safety first" is the most basic requirement for gas stations. Common safety measures at gas stations mainly include turning off motorcycles to refuel, gas station employees must wear anti-static clothing to work, prohibiting open flames and using mobile phone calls in gas stations, and not refueling in plastic buckets, etc. One of the more difficult to manage is the prohibition of customers using mobile phone calls in gas stations mobile signal jammer.

　　First of all, people have misunderstandings about the safety hazards caused by using mobile phones in gas stations. Why can't you make phone calls in the gas station? Some people think that it is alarmist that a mobile phone can cause an explosion at a gas station, and they have never heard of an explosion caused by a mobile phone. In fact, there is a certain scientific basis for mobile phones to cause explosion accidents.

　　As a radio communication tool, the mobile phone emits radio waves, which can induce radio frequency currents in the antenna that receives the radio. When RF current circulates between metal conductors, RF sparks will be generated in case of corrosion or poor contact. As long as the RF spark lasts for more than one microsecond and the energy is greater than 6 milliwatts, it will ignite the methane-air mixture. Since gasoline is a volatile substance, in the combustible danger area formed by the leakage of oil and gas tanks and natural gas pipelines, the radio frequency sparks generated by mobile phones can easily cause explosions and lead to disasters.

　　When the gas station fills the fuel tank of a car or motorcycle with gasoline through a fuel gun, the oil and vapor in the original empty fuel tank will drift outward, and the newly injected gasoline will also volatilize into the air, causing the density of the fuel and vapor around the refueling vehicle to increase sharply. At the same time, in order to make the communication signal clearer, the frequency of mobile phone use is very high, and the transmission power is relatively strong. Although it meets the national standard, it still poses a serious threat to refueling and gas stations. Because refueling and gas stations are now generally controlled by computers, high-intensity mobile phone signals will cause induction with computer equipment, and the instantaneous electronic friction between the two may ignite fuel vapor and cause an explosion. The current required to ignite the fuel gas is very small, and the static current generated by the mobile phone in the working state can completely reach this limit. If you encounter cloudy or foggy weather with high air humidity and low air pressure when refueling or unloading oil at the filling station, due to poor air circulation, the density of oil and vapor will increase accordingly, and the possibility of explosion caused by receiving a mobile phone will further increase. big.

　　In addition, because the mobile phone itself does not have explosion-proof function, if the mobile phone is used for a long time or the quality of the mobile phone itself is poor, the circuit of the internal chip of the mobile phone is prone to short-circuit, so that the mobile phone can generate a small amount of sparks at the moment of answering, thereby also Can cause an explosion at a gas station.

　　Secondly, there is only one way for customers to use mobile phones in gas stations. At present, the main way for gas stations to prohibit customers from using mobile phone calls at gas stations is to persuade, but sometimes the effect of persuasion is not ideal. On the one hand, the customer does not know the safety management regulations of the gas station, and believes that it is unnecessary for the gas station employees to let them use their mobile phones in the gas station, which is prone to rebellious psychology. On the other hand, the customer knew that he could not use the mobile phone in the gas station, but he was lucky, and one-sidedly believed that the accident would not happen when he was using the mobile phone, so he did not listen to the persuasion of the gas station staff and went his own way.

　　It is not uncommon for car owners to use mobile phones in gas stations. Gas stations should be prepared for danger. They should not turn a blind eye to this phenomenon and let it go. Effective measures should be taken to eliminate potential safety hazards and jammer gps buy ensure the safety of gas stations.

　　Method 1: In non-metallic environments (such as houses, human bodies), metal detectors can detect, but some monitors and locators have almost no or no metal parts, and metal detectors cannot detect them, so this method has limitations .

　　Method 2: The use of radio signal detectors can detect bluetooth, wifi jammer, and mobile phone communication signals, and monitors and locators will also emit such signals when they are working, so they can be detected.

　　Strictly speaking, vehicle anti-monitoring and anti-tracking is a comprehensive professional discipline. It integrates communication engineering, radio technology, electromagnetic research, information science, network security, psychology and other disciplines.

　　The method of shielding the vehicle locator signal:

　　1. If you want to block the GpS locator on the car, you must first look at the size of your car model, and then choose the corresponding power blocker. In addition, there are various GpS signal blockers on the market, and there are many types, so how do you distinguish them? How to choose an effective shield is very important;

　　2. Some people think that as long as they buy a GpS blocker, they can block the positioning. In fact, this is not the case, because the positioning includes satellite positioning and base station positioning in addition to GpS, so it is necessary to buy all shielded equipment to be effective;

　　3. This type of jammer gps can basically be powered by the cigarette lighter, so after being installed in the car, it must be ensured that the jammer gps is always in working state. If the car turns off halfway, the jammer gps will definitely be powered off, then the location information of the car will be exposed again. Therefore, it is recommended to connect the power of the shield to the battery of the car as much as possible to ensure that the device can work continuously.
