Conversion algorithm analog-digital allows compression and transmission of images structured data. The use of such an algorithm allows for a significant improvement in the quality of the received signal, further expands the dynamic range and improves resistance to rf link interference.
The flexible structure of the system allows broadcasts according to two independent sound signals (stereo) with a high degree of separation with the mesichannel through only one channel. It also allows you to monitor the battery status. It is possible to switch between stereo / mono modes using the remote control.
Digital Stereo RF Link is designed to transmit audio data in stereo mode via an encrypted digital RF connection.

The flexible structure of the system allows broadcasts according to two independent sound signals (stereo) with a high degree of separation with the mesichannel through only one channel. It also allows you to monitor the battery status. It is possible to switch between stereo / mono modes using the remote control. Mono mode provides a double increase in the acoustic signal band. The use of the frequency synthesizer greatly simplifies the selection of the transmitting frequency and allows the control of the frequency from the remote control. Check step performance of the transmitter is performed from the remote control.

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 1 also has a radio receiver paired with a transmitter in the kit. It is a simple single i.e. channel receiver without display, with the possibility of connection to the hearing aid and also with the possibility to connect to the recorder.
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.
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.
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.
A laser listening device can be assempled just in a couple of minutes and it can let you to listen through windows that are located in optimal conditions up to 1,000 meters far. In standard conditions, in daylight there is an operating range of laser listening device about 500 meters.
Functions of StealthLaser P:

virtually impossible to detect
listening and recording simultaneously
no need of plugging any transpoder inside or outside and monitored object
special optical system for quickly finding the reflect laser beam
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)
850mW end stage for transmission of audio and video signals in the 1.2GHz band. This is a professional product. The possible range of audio, video signals is up to 1-2km even on the antennas that are included. There is no problem of using directional antennas, this step will increase the range.
The device uses 8 channels for possible video – audio transmission. This is that you can independently use eight devices at the same time.
Miniature dictaphone capable of recording continuously for up to 15 days. And that's on one charge. A miniature digital voice recorder (audio voice recorder) camouflaged into a black metal keychain for professional audio recording to your internal memory with higher recording quality. 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)
Powerful and versatile, the technology breaks new ground with its ability to operate on highly sensitive and critical operations. The device comes with a multi-function device for listening through walls using a contact or needle, microphones for the phone, or room and telephone operations, and for use with when worn on the body microphone.
Clear or encrypted, powerful and versatile
With the ability to choose a clear or encrypted mode, high or low microphone sensitivity (it registers the type of microphone connected) and voice control with on/off for longer battery life, the operator has a very versatile and compact unit
Hidden audio tracking up to up to 5.6km from the control unit - up to 10m separate microphones. For each of the channels there is a selection of miniature microphones that are powered by the central surveillance control unit. The system is fast easy to set up and operate.
Noise reduction
Microphones can be covertly installed in locations that must be monitored through existing or new wiring. Digital Noise Reduction system allows conversations to be understood, even if there is high background noise, whether introduced intentionally or natural.
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.
