The smallest available micro GSM bug on the market, unlimited range. 641-WT2810

The smallest bug available – eavesdropping device in our market in unlimited range. This is actually a miniature GSM voice module. You can also hear what's happening in another city in your selected room and hear it simply on your GSM phone.

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.

Audio transmitter designed as a board with surface mounting protected by a plastic cover. The power supply forms a frame and is located on the back of the printed circuit of the board. 

The product is designed to transmit audio signals through a radio channel. You insert a flashlight and you can eavesdrop on your interest room within 100m.

Comfortable camouflage;

High sound quality;

- Easy battery replacement.

The product is designed for use on the body or in the dress. Flexible modular design allows you to hide the audio transmitter in clothing.

The product consists of three modules: compact microphone – amplifier transmitter and power unit. These modules are connected to a soft cable that also functions as an antenna.

The product is rated both for telephone line and room acoustics monitoring, with transmission of the obtained intelligence via crystal controlled radio channel.

All operation modes are user-defined and are set with internal keys or with RC. RC unit is optional. 

Basic user-defined operation modes:

Room acoustics or Telephone line control (with use of external microphone or inductive sensor accordingly);

Open/encrypted radio channel (delta modulation encoding);

Transmitter output power control (100 mW/450 mW);

VOX ON/OFF;

RC ON/OFF;

Wireless FM transmitter, bedbugs on the half of the room. Microphone Pickup Monitor Spy Mic-415

Working voltage is 3V, use two batteries 

Transmission distance is about 50 m

A normal new battery can work continuously for about one week! 

This product has a high sensitivity! You can hear very faint sounds, like silent ticking clocks.

This product uses FM modulation, you can use FM radio reveive signals. You can also use your phone's wireless connection or car radio for reception!

Microphone is built into the product, the cable is like an antenna , the switch is in the process except you can put it off when you do not want it to work so that it can increase battery efficiency!

Radio professional listening equipment built into a fully functional power grid and permanently powered from the 230V~ distribution to the UKV frequency. The device is equipped with a special microphone with controlled noise gain from the eavesdropping room with a range of 15m -25m. The device itself can be captured only within a radius of 200m.

FUNcube Dongle Pro + has the same design objectives as the original FUNcube Dongle, but we have taken into account many comments on the original FCD and have improved both performance and functionality. Although it may look similar from the outside, it's a whole new design.

In terms of performance, we have added 11 discrete hardware filters to the front, including narrow SAW filters on amateur 2m and 70cm bands. This has a hugely beneficial effect on blocking the front-end, especially on the VHF.

There is also a new LNA used with much better performance, which improves OIP3 to 30dBm (around 10dBm). In addition, the rf grades are at 3.15 V compared to the original 1.5 V FCD, which significantly increases the dynamic range.

Special Multi-Channel Receivers

A special multi-channel receiver is designed for radio reception.

It is possible to choose to receive an open radio channel + Spectrum Inversion Decoder; or open radio channel + Delta modulation decoder.
