Thanks to the 5 x-split microphone, the voice recorder can record sound from a certain direction over a distance of up to 15 meters and significantly reduces the background noise of the microphone. Why is that possible? If the recorded object is located sideways from the direction of the microphones signal "cancel - cancel" due to the phase difference of downloading the sound of each microphone.

With a newly redesigned user interface, Sound Cleaner II provides high-performance intuitive tools for best results. Powerful noise filters and other special features help you get results faster than ever.

This camera is mounted on a malfunctioning GSM phone. Put it simply on the table and no one sees that you are monitoring it, it has the ability to make both audio and video transmission. The camera is positioned to directly track the person in front of the phone. ( That's when you're antennae. Classic GSM phones have a camera in a flat place of cover, so its location prevents people from tracking.) This technology was developed only for hidden surveillance of persons.

The built-in high-quality electric microphone with compression amplifier with an extremely wide range of sensitivity control and noise filter (ACOUSTIC ZOOM) allows you to capture the sound of the compressor and the ticking of the wall clock. By pinching the short-circuit clutch in front of the module, it is possible to optimize the noise properties for voice operated recording (VOR) recording systems.

The device is able to eavesdrop on conversations through various obstacles by amplifing sound vibrations.

Wiretap through the walls classic ver-929-435, High Sensitive Partition Monitor.

The device is able to eavesdrop on conversations through various obstacles by amplifing sound vibrations. Its main advantages include the ability to eavescent through different types of material, the ability to record an SD card, the choice of an eavesdropping method via an antenna or probe, and the ability to operate continuously for 100 hours.

Set consisting of an audio receiver and three bedbugs (a large-range bedbug, a medium-range bedbug and a miniature bedbug). The receiver uses a quality lithium battery with a capacity of 800 mA/h. Its dimensions are 90 x 57 x 23 mm.

The range of the large-range bedbugs is up to 2800 metres in the open and the battery life is up to 12 hours, its dimensions are 50 x 33 x 20 mm. Medium-range bedbug range is 500 meters in the open, battery life is 36 hours because it uses a high-quality lithium battery CR2032. Its dimensions are 25 x 22 x 15 mm. The smallest bedbug has a range of 500 meters, the battery life is also 36 hours, but its dimensions are only 20 x 10 x 8 mm.

Portable wireless receiver and receiver next generation 2013.

Professional UHF eavesdropping with the ability to record on a memory micro SD card. This UHF interception has a range in ideal conditions (there are no obstacles between the receiver and the transmitter) up to 150 meters and offers perfect sound quality (in the room you will also hear the clock ticking). In the case of eavesdropping, for example, in the office, the range is shorter (about 50 meters), because the walls are obstacles to signal transmission.

So if you want to be able to remotely eavesdrop on the selected space while being able to procure a record, then this interception is the perfect option for you. This is a professional eavesdropping suitable for demanding users.

UHF wireless bedbug CW423 - sigint complete Microsada, Portable wireless transmitter assembly and receiver next generation 2014.

Wireless Audio Transmitter (bedbug) with voice recording, range up to 100-500m as provided in 430MHz band

Microwireless audio transmitter, professional audio collection.

It is made up of a transmitter and receiver.

The range has 100-500 m, where the sensitivity of the microphone in the room is so good that you can hear the ticking of the clock.

In addition, you can also record audio signal – chats from 2GB SD card support, or via external JACK output

The device is used to eavesdrop on and monitor people from any part of the globe using the GSM (mobile phone) network. Just insert any SIM card into your device (some models are for the operator only), PIN code protection must be disabled on the SIM card. When you call the SIM number, the device automatically receives the call and you can hear everything that's going on in that environment. The device can be controlled using SMS commands. By sending an SMS to the SIM card number, you can create a snapshot of the environment, an audio recording, even a video from the environment where it is located.

This device allows you to spy on anyone, anywhere. You just need to buy a new SIM card and put it on your device. You can dial a SIM card number immediately, automatically answer the device, and it works like a phone with automatic lifting without a microphone. So you can hear anyone talk about you or everything when you call your SIM card number on your phone. No one will notice, because this device looks like a USB hub or a small USB device. But in reality it's a spy device - a bug. If you place the device next to your computer and plug it into a USB port, the device is charging so you can call the device anytime, anywhere, or you can put it in your car or other location where it will work for 1 to 2 days.

LVA-i is an interactive multi-language and fully automated questionnaire platform based on the technology of vorate voice analysis.

The standard application offers a series of questions in the following areas:

c Workplace theft

c Corruption and bribery

c Reservation and protection of information

c Drug use

(ć) the effect of alcohol

c Gambling

The eavesdropping transmitter operates at a high and completely discrete frequency in the UHF band. The transmitting toss is controlled by saw resonator. The device is equipped with a special microphone brand knowles with a large sound range of 15-25m.

You get the cleanest audio from the eavesdropping room in hifi !!!

The device is fundamentally different from the VHF eavesdropping devices, especially with a short but precisely tuned helical antenna. In practice, this means that the energy from the power supply cell is more efficiently used, while the transmitter's range is significantly greater than that of the VHF transmitter, the same power. This product is the highest quality and at the same time the most expensive equipment on the market.
