Wireless charging of audio transmitters

This product is designed to control acoustic information transmitted over a digital radio channel.

This set is designed for covert audio monitoring with covert transmission of audio information via a radio channel and with the possibility of remote control of the radio channel.

Digital Stereo RF Link with REMOTE CONTROL II VIP

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. 

The transmitter is designed to control acoustics and transmit acoustic information via a radio channel.

Multifunctional wireless FF audio sound system. Flexible, long-range supervision.

Listening through walls

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

Designed to control acoustic information via elements of building structures (wall, ceiling, etc.) With the transmission of information via a radio channel with quartz frequency stabilization.

The product is designed to control acoustics and transmit acoustic information via a radio channel.

The acoustic information transmission set is intended for controlling the acoustics of a room with information transmission via a 220 V network on auxiliary carriers.

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.

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.

The product is designed to control acoustics and transmit acoustic information via a radio channel. It is a universal basic module for built-in radio transmitters.

Transmission of acoustic information via a two-wire unshielded cable.

The product is designed to control acoustics and transmit acoustic information via a radio channel. It is a universal basic module for built-in radio transmitters.

The miniature digital voice recorder is designed to record high quality sound.

This product is intended for the control and transmission of acoustic information via a radio channel.

The recorder is designed to control and record acoustic information obtained using a small accelerometer (stethoscope sensor) through the elements of building structures (wall, ceiling, etc.), or using a remote cable microphone (cable length up to 10 km).
