DJI launches drone self-interception system

The recent frequent occurrence of drone accidents shows that drones as a consumer-grade technology product have continued to gain popularity. At the same time, the level of safety of drones is also increasing.

he Verge reported that the famous Chinese drone manufacturer DJI launched a new self-intercepting software system “Geospatial Environment Online” (Geospatial Environment Online, GEO) this week, which can prevent DJI drones from flying in No-fly zone.

The GEO system allows users to know where drones will be restricted, whether it is due to regulatory requirements or safety issues. This is DJI’s innovative approach to respond to the Federal Aviation Administration (FAA), which has been calling for more rules for drone flight over the past year.

According to The Verge, the drone jammer can prevent DJI UAV systems from flying in no-fly zones such as airports and Washington, D.C., and can also let users know which airspaces are temporarily restricted from flying, such as areas close to forest fires or major sports events. Sensitive areas around prisons and power plants are also restricted in the system.

However, users of DJI drones can still temporarily exit the GEO system and unlock some flight restrictions. However, if an accident occurs, the user will be checked by the regulatory authorities. Users who want to temporarily unlock must have a DJI-certified account and have registered credit card, debit card or mobile phone number information. If the drone is found flying in an unauthorized airspace, the supervisory authority can find the person in charge. However, drone users cannot close all flight restrictions, and areas such as Washington, DC are still completely banned from flying.

Something about the frequency of GPS jammers

GPS jammer is the main role is to prevent GPS tracking device. We were told about how it works in the article “what is misery”. If you are concerned about someone chasing you, you may need a GPS jammer to prevent others from using the GPS tracker to track you.

Before you buy it, there is something you should be aware of about these devices. One of the main issues to check when purchasing a GPS jammer is its frequency of operation. Because GPS tracking devices use a variety of frequency bands, especially the GPS L1 band, but there are other frequencies to use, so you need to know the frequency and choose what you need to set their working frequency. Please note that the frequency of the jammer used must be the same as the frequency used by the GPS tracking device for the jammer to work effectively. There are hundreds of GPS jammers on the market so it should be easy to find a jammer that suits your needs and requirements.

If you don’t know the frequency of these trackers, don’t worry. There are many types of GPS jammers, some of which block a primary GPS L1 frequency, and some may be able to block several at once. Of course, there are many high-end models that can block any tracking frequency (GPS L1 L2 L5, GLONASS, Galileo, Compass, etc.) If you want to be sure you haven’t “followed” these tools are yours Option, and of course these devices can be quite expensive, so you should determine how much money you will be making. Surely the GPS jammer can help you keep GPS tracking.

GPS jammers have different qualities – battery life and the frequency of assistance. The most important is the frequency of device support. Battery life is also an important characteristic, and if you plan to use Jammer for a long time, it should be checked carefully. In general, the battery life of portable jammers cannot be used for a long time on a single charge. If you’ve been wanting to use Jammer for a long time. Desktop jammers are better because they are generally used when loading.

Talk about the 4 advantages of wireless signal jammer

In the last few years, various types of cell phone jammer have emerged in an endless stream. We are dazzled and dizzy. In fact, not all products are suitable for us to apply to ourselves. Some products are public, so they are not suitable. There is a very special jammer used in other fields by us, and it also appears in front of us. Its name is wireless signal jammer. So what are the advantages of this type of product?

When we use a wireless signal jammer, you will find that no matter where we are, as long as we can turn on such a jammer, no one can search for our wireless signal. In other words, home The effect of the product is more obvious than that of common public products. In such an environment, we can always shield all signals easily, but if we use a public shield, then the shielding effect may be unstable The problem, so we need to understand the specific use effect.

What are the advantages of wireless signal jammers? The following editor from Chengdu Saiyue will explain the 4 advantages of Saiyue wireless signal jammer one by one.

1. Wide application
Wireless signal jammer is mainly used in examination rooms, but not limited to examination rooms. They can also be used in prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, Only used in libraries, school dormitories, special security and confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitaries guarding the scene).

2. Strong pertinence
Wireless signal jammers can be mainly used for domestic college entrance examinations, domestic college entrance examinations, adult college entrance examinations, self-study examinations and various colleges and universities examinations, as well as various middle schools, technical secondary schools, vocational high schools, prisons, detention centers, conference rooms, etc. Use mobile phones to cheat, send text messages, Adverse effects caused by communication with outside prisoners, collusion with others, etc.

Three, the shielded signals are diverse
Effectively shield GSM/CDMA/DCS/PHS/TD-SCDMA/WCDMA/WIFI/TD-LTE/FDD-LTE.

Fourth, model advantages
1. Using high-dispersion aluminum alloy shell, low working temperature, more stable shielding effect.
2. Built-in silent turbo fan, low working noise.
3. Separate power adapter. 12V/24V DC power supply work, convenient for vehicle mobile work.
4. The antenna is externally designed, and one end of the interface is unified to make the appearance more beautiful and decent. It also has an anti-loosening design, and the antenna and the host have a marked working frequency band to facilitate one-to-one correspondence.

A major feature of the wireless signal jammer is that it is easy to carry, because it is relatively small, so when we go out, we can also carry it around, but there are other types of products around us. There are major drawbacks. Because the public products are relatively large in size and heavy in quality, they may consume a lot of manpower, material and financial resources during the carrying process, and sometimes even extremely difficult problems occur. In comparison, the reputation of household products will naturally be more ideal and more convenient.

Mobile phones bring safety hazards to gas stations

The number of small cars in Shenzhen is growing rapidly at a rate of 200 vehicles per day. How much do new drivers know about the safety regulations of gas stations? Yesterday, the reporter randomly interviewed several gas stations in the city and found that although the safety warning signs in the gas stations were very eye-catching, many drivers turned a deaf ear to the safety regulations such as banning mobile phones and turning off vehicles when refueling.

Most drivers have used their mobile phones at gas stations. How many people have complied with the safety rule of “turn off the vehicle when refueling”? The reporter interviewed several gas stations in the city and learned that 80% of novices often need to remind the fueler to stop the fuel when refueling. Old drivers generally do not need to remind the fuel to stop, but some old drivers do not want to stop the fuel because of trouble.

At the Sinopec gas station on Hongli Road, Ms. Huang from Meilin Village told reporters about her dangerous experience. Once when she refueled, she got out of the car without stalling, and the fueler reminded her to refuel after stalling the car. When she was refueling, her cell phone rang, and the fueler asked her to stand farther away to answer the phone. At that time, she felt a little unhappy in her heart, thinking that the fueler was very unkind. When she was standing far away on the phone, she suddenly heard a strange noise from the spray gun being refueling, and saw a sudden electric spark flashing from the front of the car. Although the spray gun automatically stopped refueling later, Ms. Huang was shocked. She told reporters that if it weren’t for the reminder of the fueler, it might have caused a catastrophe.

At a gas station near Liantang in Luohu District, 15 vehicles came to refuel within 20 minutes. Among them, 9 drivers were talking and laughing on their mobile phones while refueling. When the fueler was refueling a car, the driver’s mobile phone rang, and the driver picked up to answer the call. Although the fueler saw this scene, he did not remind the driver. On a pillar next to him, there was a post “No mobile phone use”. The striking goal.

During the reporter’s interview, two-thirds of drivers said they had used their mobile phones at gas stations, and many drivers even said they didn’t know this rule at all. A Mr. Zhu said: “I have never heard that calling on a mobile phone in a gas station will cause an explosion.” Many drivers think this is a big or small matter, and there is no need to make a fuss. Illegal operations can easily lead to accidents. It is common knowledge that fireworks are strictly prohibited at gas stations, but it is not clear to so many people that dialing or receiving mobile phones at oil depots or gas stations or refueling without turning off the flame may cause an oil and gas explosion. As more and more people use their mobile phones at gas stations and do not turn off the gas to refuel, relevant people warn that such illegal operations may become the fuse of an oil and gas explosion, and its danger is tantamount to playing with fire.

A person from the petrochemical company said that the density of oil and gas around the vehicle will increase sharply when refueling. At this time, the electronic friction generated by the mobile phone in the transmitting or receiving state may ignite the gasoline and cause an explosion. In fact, the manual of general mobile phone products will indicate: Do not use the mobile phone at the gas station! At the same time, the reporter learned that only last year, gas stations in Yueyang, Zhengzhou, Changsha, Lanzhou and other places had exploded due to the use of mobile phones, causing serious incidents of casualties.

What are the advantages of installing a mobile phone signal jammer in an auditorium?

The rapid development of mobile communication has brought great convenience to people’s work and life, but the side effects caused by mobile phones have become increasingly apparent. The unsafe factors of mobile phones are mainly reflected in the fact that in important secret-related places such as agencies, factories, enterprises and institutions, intentionally or unintentionally dialing a mobile phone or forgetting to turn it off may cause a leak at any time. In some important secret-related occasions or meetings, the use of mobile phones is prohibited. At this time, we will use the cell phone jammer, which is a green new information security product that is newly developed using modern high-tech. The principle is similar to that of the communication signal source. A fan-shaped shielded space is customized according to the power of the jammer, and the normal wireless connection between the signal source and the mobile phone is cut off, so that the mobile phone in this space cannot be received or called. To achieve the purpose of compulsory banning of mobile phones, so as to ensure the safety and confidentiality of the scene. The appearance of the equipment is simple and elegant, solemn and beautiful; efficient and intelligent cooling and heat dissipation system, stable performance, safe and reliable; built-in professional directional antenna, without external antenna, can be directly powered on by the mains; good electromagnetic compatibility, integrated design and installation of the whole machine Convenient and simple to use and manage.

Criminals complete the theft in 20 seconds

Recently, the border defense detachment of Dongguan City, Guangdong reported that a series of car property theft cases that occurred in service areas such as Guangzhou-Shenzhen Expressway Houjie this year have been solved. Criminal gangs used signal jammer to transmit signal interference, causing car owners to lock the car and steal the car. Inside property.

From the surveillance video, we can see that in the Dalingshan service area of the Guangzhou-Shenzhen Expressway, a man wearing a white short-sleeved T-shirt got off a black car. He seemed to be moving his muscles and bones. In fact, he was just pretending to rest and looking for the target of the crime. . Soon, a gray SUV drove into the service area and stopped. A man and a woman in the car closed the door and left.

At this time, the criminal suspect appeared again, and saw him approaching the SUV car casually, opened the door easily, quickly got something from the car, turned around and got into the corresponding vehicle and quickly escaped. The entire theft process took less than 20 seconds.

In the end, the Hunan suspect Tan and his associates were arrested by the police in a hotel in Dongguan at the end of September. In the face of hard evidence, Tan and his associates confessed to the crime.

How to deal with “car jammers”?

①When traveling or shopping for parking, try to choose a public parking lot with camera monitoring. Especially when parking overnight, try to park in a parking lot that is supervised by someone.

②When locking the car, pay attention to the phenomenon of locking the car. For example, when some cars are locked, the two rearview mirrors will be retracted; when some cars are locked, the turn signal will flash twice, etc. When an abnormal lock is found in the use of an electronic lock, a manual lock should be used to increase the safety factor and try to avoid unnecessary losses.

③When you lock the car, pay attention to whether there are suspicious people around. Before you leave the car, pull the car door with your hands to make sure it is locked.

④Don’t put valuables such as leather bags, mobile phones, cash, etc. in the car, so as not to let criminals catch them.

6 ways to prevent decoder theft

When the car owner locks the car, it intercepts the decoded signal sent from the car’s key to the car’s central control lock device, analyzes the frequency and data in it, and copies this signal to control the car door lock and easily steal the owner’s car or car property.

The car GPS jammer has a low technical content. The principle is to send out a frequency similar to the original car key signal, and the signal is strong, covering the original car key signal, making the vehicle unable to lock the door, and taking the opportunity to steal the property or the vehicle after the owner goes away .

“This kind of device is a decoder, rather than a codecutter, because it mainly relies on intercepting the signal to copy the signal.” Master Su said, the public need not be too panic, because only when the owner of the car is opening or locking the car, it is illegal. Only the disciples can take advantage of it. However, in order to avoid property damage, Master Su reminded the majority of car owners to be more careful when parking.

Learn the following 6 tips to reduce the chance of theft of vehicles and their belongings:

1. When you lock the car, pay attention to whether there are suspicious persons within 10 meters.
2. When locking the car, the owner should not be too far away from the car to reduce the range of sensor sensing by the decoder.
3. When using the car anti-theft alarm, install a mechanical anti-theft device and install several concealed locks, such as steering wheel locks and gear locks, so you are not afraid of any decoder.
4. Look for a more side-by-side anti-theft method, do not install the anti-theft device in a fixed position, which increases the time of the thief’s crime, and the thief will lose patience, thereby reducing the chance of successful theft.
5. Load the GPS global positioning system on the car. Even if the car is stolen, the police can quickly locate the stolen vehicle and retrieve the stolen vehicle as soon as possible.
6. It is still necessary to emphasize that you should not put valuables such as leather bags, mobile phones, cash, etc. in the car to avoid losses caused by criminals.

How does cell phone signal jammer work!

The current cell phone jammer is full-band. It can shield all the 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals under all the three operators of China Mobile, China Unicom and Telecom. Its principle is sent by itself. The frequency interferes with the mobile phone receiving the frequency from the base station and wireless router, so as to achieve the purpose of shielding them. Generally speaking, the working principle of the mobile phone signal jammer is that the frequency emitted by the jammer interferes with the normal frequency of the mobile phone receiving the base station, making the mobile phone unable to connect to the base station, and thus unable to make calls, receive and send text messages and surf the Internet.

mobile signal jammer 5G

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone. The mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc.

No matter what cell phone card you use, as long as the cell phone cards under China Mobile, China Unicom and China Telecom will be blocked. WIFI will also be blocked. Unless you use 5.8G WIFI to surf the Internet, because the standard configuration of the jammer does not shield 5.8G WIFI. However, some schools may let jammer manufacturers order 5.8G frequencies just in case, so this is not guaranteed to be absolutely foolproof.

Whether it is a high power jammer or a small signal shielding instrument, its principle is to interfere with the mobile phone to receive the normal frequency sent by the base station through its own frequency, so that the mobile phone cannot contact the base station, so as to achieve the purpose of shielding. The principle of shielding WIFI is actually that the signal jammer will send out the corresponding frequency when it is working to interfere with the mobile phone to receive the normal frequency sent by the router, so that the mobile phone cannot connect with the router and cannot access the Internet normally.

Mobile phone signal jammers are mainly used in some school examination rooms, dormitories, detention centers, military units and confidential meeting rooms, etc. So as long as you enter these places, your mobile phones will be shielded, and you will not be able to make calls, receive text messages, and access the Internet normally. There is no exception, and nothing can be set to avoid being blocked.

Playing with mobile phones while praying, priests install mobile phone signal jammers

Maybe you are thinking, is it really appropriate for Father Madonna to use a cell phone jammer privately? According to him, his actions have been supported by the local police. Obviously, not everyone is welcome to the priest’s measure. The owners of the local store are very upset. They claim that the priest’s signal blocker has interfered with their credit card machines.

Now, people are increasingly unable to leave their mobile phones, even when praying. This problem has suffered from the priest Michele Madonna of the Church of Our Lady of the Holy Mountain in Naples, Italy. According to the “Daily Mail” report, the godfather finally found a solution-cell phone signal jammer. Madonna bought this device for $60. The priest said that he did this not because of his lack of patience, but the embarrassment he saw when he advised people to turn off their phones and concentrate on praying.

Maybe you are thinking, is it really appropriate for Father Madonna to use a cell phone signal jammer privately? According to him, his actions have been supported by the local police. Obviously, not everyone is welcome to the priest’s measure. The owners of the local store are very upset. They claim that the priest’s signal blocker has interfered with their credit card machines.

In some countries, the use of signal jammer is illegal. In the first half of this year, a man in Florida, USA, was fined $48,000 for driving around with a cell phone signal jammer.

The anti-drone market has a bright future

Nowadays young people like to play with drones, because small drones can bring people unlimited fun, but some young people who have a shallow understanding of the law will use drones to spy on others’ privacy, thereby invading others Human rights. In order to be able to restrain and prohibit these young people from doing wrongdoing, the drone jammer was launched.

With the continuous progress of society and the increasingly moderate price of drones, more people will own drones in the future, so the intensity of the management of drones will increase, and it is inevitable that some people will not comply Laws, control drones flying everywhere. Or do not register the UAV to do some illegal things, then after the anti-drone system, these illegal things can be properly resolved, that is, interfere with the normal use of the UAV. Forcing the drone to land, thereby ensuring the safety of national airspace and the safety of social security.

In short, the prospects for the development of the anti-drone market are broad, so investors who want to invest may wish to get familiar with the rules as soon as possible to lay a solid foundation for future gains.
