Listen Through Walls Microphone; with remote infa-red (IR) contact wall microphone

This is a professional high-end Listen Through Wall unit which uses remote invisible infa-red technology with superior listening quality.  Constructed in the finest of materials and designed to government standards - the quality and engineering is truly magnificent enabling the user to listen through solid concrete walls up to 23 inches thick!  The unit is so sensitive that you can place the direction the person/s behind any solid wall from over 800 meters away!

You can simply attach the contact wall microphone to any wall surface and then, without the need to be physically at the target location thereafter - remotely listen from some 800 meters away using the supplied infa-red binocular Receiver!

This LTW device is equipped with an automatic sound filter which helps eliminate unwanted background noises plus a sound limiter for reducing any possible foreground bangs that could damage your ear drum.  The transducer casing is made of full aluminum and coated with special plastic providing an excellent shielding against radiation such as GSM or ISM interferences.

An advantage of using IR (infa-red) over UHF transmitting devices is perfectly legal for use within the EU.
