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.

Watching and mixing 8 audio channels - portable set. One operator is able to monitor and mix up to 8 microphones. Each channel has its own smooth high amplification level for pre mixing using a 10 bar volume indicator.

Very sensitive miniature microphones give high-quality sound via cable up to 10 km long. As a wired microphone the system is immune to detection of radio frequency detectors. There is also an output device for recording.

The ESH800K suppresses background noise and delivers instant crystal clear and intelligible sound. This is achieved by the operator choosing one of 8 levels of Digital Signal Processing (DSP) to match the noise in the environment, whether from air conditioning and from a construction site, or deliberately introduced noise.

The eavesdropping transmitter operates at a high and completely discrete frequency in the UHF band.

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 knowles microphone with a sound range of up to 15m -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. 

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

A miniature digital voice recorder (audio voice recorder) camouflaged into a colored metal roller for professional audio recording to your internal memory. The device is characterized by extremely small dimensions and weight, long enduminate, very low power consumption, wide frequency range, large dynamic range, highly sensitive built-in microphone and voice recording activation (VAS) function. ( voice activation – recording is only performed if you hear sound in the room)

Complete audio surveillance through the walls. Comprehensive cable set for listening through the wall. Up to 5 walls can be monitored at the same time.

If your target is on the other side of a solid wall even under poor surveillance conditions, you can listen locally or remotely with a high degree of flexibility for temporary or permanent monitoring using this sophisticated amplifier and accelerometer.

Exact location of the target

The accelerometer and 2 channels of the control unit with instant stereo display more than 12 meters apart give exact information about what is happening on the other side of the wall. Microphone sensitivity level is adjustable on each (stereo) channel.

A miniature digital voice recorder (dictaphone) camouflaged into a wooden jewelry box for professional sound recording to your inner memory. The device is characterized by extremely small dimensions and weight, long enduminate, very low power consumption, wide frequency range, large dynamic range, highly sensitive built-in microphone and voice recording activation (VAS) function. ( voice activation – recording is only performed if you hear sound in the room)

LVA-i is an interactive multi-language and fully automated questionnaire platform based on the technology of vorate voice analysis. It provides an unprecedentedly profound analysis of the integrity and risks associated with the test person through a series of pre-prepared questions. 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

Multichannel surveillance. easy to use LCD display allows viewing operator to monitor up to eight channels. On-screen information includes channel identification, signal strength and status (battery transmitter level, on/off) that supports successful monitoring of traffic. When recording tracking activity is needed EPR is equipped with recording output device.

Digital system with remote control

Using the controls on the receiver, the operator can switch between continuous, VOX and off modes, and change the output power setting on each transmitter. This robust receiver is powered by a network adapter or internal rechargeable batteries that provide up to 8 hours of operation. The system includes a magnetic mount antenna of the vehicle.

Audio surveillance and counter-surveillance agent case

The new upgraded Agent Case provides an experienced professional with carefully selected devices for cable and Radio Frequency hidden viewing and recording. This is complemented by a powerful handheld RF and camera detector lens.

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.

SET 2 also has a radio digital receiver paired with a transmitter in the kit. It is a digital multi-channel digital receiver including the possibility of setting the frequency in the 400MHz-450MHz band, with the possibility of connecting to the hearing aid and also with the possibility of connecting to the recorder.

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.

A miniature digital voice recorder (micro audio dictaphone) camouflaged into a leather pendant (embossed leather) on keys for professional audio recording to your internal memory. The device goes on sale in a beautiful wooden case. 

The device is characterized by extremely small dimensions and weight, long enduminate, very low power consumption, wide frequency range, large dynamic range, highly sensitive built-in microphone and voice recording activation (VAS) function. It records a routine conversation up to 12 metres away with the high quality of interview registration.

Voice recorder capable of recording a conversation from telephone line 650-D956A

To which you can record 72 - 1120 hours of recording directly to MP3 format using a built-in or external microphone, as well as directly record the phone's calls from a landline !

You just plug it into a landline and the answering machine takes care of everything. Record all conversations from your landline.

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.
