Any mobile device can be listened to. This does not require the owner's consent. A large number of programs have been invented, with which you can control the microphone and camera in any phone. And this can be done remotely. The owner will not suspect that he is being tapped. After all, there will be no changes in the operation of the phone, indicating the fact of espionage. Any secret information can be recorded and dropped using a simple mobile phone. You don't even need special spy equipment.
Turning off the phone completely will not save you from listening. A person can be spied on, even if the cell phone is taken offline. Modern methods allow eavesdropping on any gadget. Therefore, if a person suspects that he is being monitored, then you can use a mobile communication damper. By connecting such a device, you do not have to worry about your safety.
There is another good reason why you need a communication suppressor. This is to ensure the silence during public speaking. If the speaker is annoyed by phone calls, beeps and melodies while delivering a speech, then you can use a neutralizer. The device will provide a fertile environment where the audience will not be distracted by extraneous noises of mobile phones.
Signal jammers are used to neutralize wireless communication channels 3G, 4G, Bt, Glonass / gps. This is usually done in places where the use of the ranges listed above is prohibited or desirable.
In some cases, cellular dampers are used as protection during negotiations. The device can be used both separately and in systems of mass protection of conversations in office buildings.
The weak point of any mobile phone is the microphone. From a long distance it can be activated using special means, and then eavesdrop on all conversations in the office where the gadget is currently located. Therefore, any mobile phone in our time is a device for transmitting and reading information.If a person has access to classified materials, then he will have to protect his phone with a communication jammer. Confidentiality of negotiations is impossible without the use of a damper.
Before choosing a device, it is worth knowing which parameters to pay attention to:
The distance over which cell jammers work varies. The range of operation largely depends on the power of the device and the distance between the base station of mobile operators to the radiation source of the phone damper. Typically, devices for jamming cellular communications are produced with a range of 2 to 50 meters.
One and the same signal neutralization device located in different parts of the same building will produce a different damping effect for certain telecom operators. This suggests that the power of the wave from the base station differs in different parts of the premises.
Strong suppressors are more expensive than their less powerful counterparts. When buying such a product, you need to check it. You will need to test all the functions of the device on your territory. Indeed, in different conditions, the device can produce a different range of action. The user needs to make sure that the purchase suits him in all respects.
Signal suppressors are produced in circular and directional action. The first ones work on a certain diameter near the apparatus. The latter act on a specific place, emitting a signal in a strictly defined direction. Therefore, when choosing a wave damper, it is necessary to take into account the distribution radius and the range of the directional signal effect.
Modern manufacturers produce outdoor stationary and portable units.
Stationary suppression devices are needed to jam a signal of a certain frequency range along a given radius, provided that the power supply is constantly supplied from the 220 V network. Another power option is a car cigarette lighter or other methods of supplying electric current. The installation of the signal muffler is carried out indoors and is moved in rare cases. This is due to the size of the device. In most cases, such devices are used:
Small devices stand out for their dimensions, due to which they are easy to transport and will always be there. The battery charge allows you to block the signal while on the road or where there is no fixed electrical network.
For portable devices, signal jamming occurs within a small radius, which allows for personal safety not to affect others. Another criterion in their favor is low cost. All this expands the possibilities of application:
There is no specific device that is better at everything. Each suppressor is good for a specific task that can be accomplished with it. Here we will talk about the devices that are in the greatest demand among consumers, indicating the features of the devices.
A novelty for suppressing mobile phone signals - "Alligator 80 Unified State Exam" allows you to block cellular signals and data transmission via the mobile Internet in classrooms and offices during examinations or important negotiations. The prototype is the successfully implemented model "Examiner 80 Unified State Exam".The new model is more expensive, but it also has more options. Suitable for use in classrooms, universities, company meeting rooms.
Experts advise to mount the device at the highest point of the office or room away from metal structures that can serve as a screen. Before mounting, you need to attach the supplied antennas and adjust the settings for each band. When operating a suppressor in a small room or room, it is worth setting half the power or a little more so that the suppression radius does not go beyond the office, interfering with other office inhabitants.
The signal blocking device is stationary and has an impressive radius. It has a wide blocking range and the ability to suppress individual frequencies. Blocks mobile communications, data transmission on the Internet, spy devices using the same frequencies. With the help of 6 antennas, efficient work with each subband is performed under any conditions of use.
The model is irreplaceable:
The device has six transmitters, each with a separate antenna with a radius of 10-40 m (with a signal level of 75dBm). The blocking device will provide a confidential meeting, seminar, scientific presentation, prevent information leakage, annoying calls.
The radius of work depends on some criteria (obstacles to work, the value of the signal level). Suppression occurs in two planes: horizontally, vertically. After launch, a ball is created. There is a connection outside of it, but there is no inside. This operating principle ensures reliability and efficiency. If the device is placed on the 2nd floor, there will be no communication on the 1st and 3rd floors.
The device for blocking signals of mobile phones "Sprut" carries out the suppression of cellular communications and data transmission, which uses the mobile Internet. The channel is blocked in any modern network, including the 4G, LTE / WIMAX standard, it has the ability to additionally block GPS devices. The radius of effective work is 50 m. Using the device, you can provide confidential meetings in business, conduct various seminars, block tracking of trackers, information leaks, and prevent annoying calls to the phone.
The range depends on external sources (obstacles, how strong the signal from the operator, etc.). Suppression occurs in two planes: vertical and horizontal. After launch, it creates a ball around itself, located in its center. In the inner part of the ball, there is no connection, on the outer part it is present. The approach provides high blocking efficiency and reliable protection. If it is placed on the 2nd floor, then there will be no communication on the floor above and below.
The Black Hunter 800 mobile phone blocking device has a long range of up to 50 m. It is equipped with 8 operating ranges, each of which has its own antenna and adjustable power. It can be used to suppress mobile communications and the Internet using Wi-Fi standards; NMT (Skylink); 3G / 4G. The metal body allows you to work around the clock. The aluminum case is used for the stand, it has a nice design.
The unit generates interference in the form of noise in the required frequency range. This helps prevent information leakage and unauthorized recording using mobile devices. The jammer blocks cell phones and other devices that use the GSM network, high-speed networks, and wireless data transmission.
It can be used not only to protect information, but also the working atmosphere (in the office or assembly hall) to ensure order (in the church, cinema, theater) and as a control technique (in the classroom or classroom).
When choosing portable mufflers for mobile channels, or as they are called in a simple way - jammers, it is almost impossible to choose the best model. Different brands have both pros and cons. Therefore, when choosing, you need to look at the specific task that the jammer should perform, and select the right one for a specific purpose.
This cell phone jammer has some very good characteristics that make the model quite popular. Berkut-8 has a fairly good autonomy, it can operate on a battery for about 1 hour. In addition, its range of action reaches 20 m, and the dimensions of the gadget are quite compact. Suppresses channels in 8 frequencies, charges from a standard outlet or from a car cigarette lighter using a special adapter. If necessary, you can select those frequencies whose channel you want to mute.
The dimensions allow you to put it in your pocket, and move freely in any direction, without fear that someone will be able to track the movement or overhear an important conversation. Very unpretentious in work, resistant to natural temperatures.
Thanks to the powerful lithium battery, you can be sure that the device will keep the battery charged for an hour of continuous operation.
Can be used while driving. The kit includes a special adapter that allows you to charge the device from the cigarette lighter.
The Berkut-6 mobile signal jammer has an excellent range, rather compact dimensions and allows you to charge the battery, both from the outlet and using a car cigarette lighter. The device can jam 6 frequencies, which include mobile communications and the Internet. Using a special toggle switch, you can selectively muffle signals.
If you carry such a device with you, you can be sure that at a distance of 20 meters to the side, it will not be possible to use any spyware and devices. Thus, it will be excluded the possibility of listening to the phone, tracking movement and video surveillance of a person in whose pocket there is a similar signal suppressor.
It is almost impossible to answer such a question, because it is necessary to take into account and consider each case on an individual basis. If it is necessary to protect the office of the company from eavesdropping on competitors or other people, it is better to choose communication mufflers with a long range. The same should be done during the exam, to eliminate the signals of the mobile phones of the examinees. Therefore, it would be better to use stationary, more powerful mufflers.
If the device is to be used for personal purposes, then a portable silencer will be enough. The range of such a device is quite enough to ensure personal safety.
