Using a directional microphone
When we think of a directional microphone, we often think of a large device, something that mainly occurs in the film industry. However, there are many more types of directional microphones, from very small and almost invisible to wall microphones.
Is using a directional microphone legal? Yes, when sound recordings are made with the permission of others. Certain rules apply to eavesdropping with a directional microphone. For example, it is not permitted to simply make hidden sound recordings public. So check whether the use of such a microphone or the distribution of sound recordings is permitted.
How a directional microphone works
You know what you can do with the directional microphone, but how does this device work? Many directional microphones are equipped with a kind of satellite dish that picks up sounds. You connect the directional microphone to recording equipment. However, there are also mini eavesdropping directional microphones that store recordings internally or transmit them directly, making it possible to listen to them now or at a later time.
Mini in-ear directional microphone
A modern solution for the traditional directional microphone is the mini listening device for the ear. Three different earpieces make this microphone multifunctional. The mini directional microphone is nothing but a sound amplifier. You wear this in your ear, which offers the option of listening to conversations up to 15 m away. Thanks to the volume control, you can determine the volume yourself.
The mini directional microphone for the ear runs on a button cell battery. No hassle with cables: eavesdrop on conversations almost inconspicuously.
Traditional directional microphone with built-in binoculars
Eavesdropping and watching from a distance of 50 m is possible with the directional microphone with built-in binoculars . This microphone not only makes 12-second sound recordings, but can easily be connected to a digital spy recorder. This makes the recording time a lot lower. The built-in binoculars are very practical: with an 8X magnification you can look at what you hear.
Professional wall microphone
Directly eavesdropping on conversations or listening to them at a later time, directional microphones are widely used. Cheaper microphones amplify the sound moderately, so the maximum distance is between 15 m and 50 m. If you want to amplify the sound optimally, use the professional wall microphone . This amplifies the sound up to 50,000 times, which is an unprecedented achievement.
The wall microphone is equipped with thin needle microphones that fit perfectly between cracks and seams. But that's not all, because the needle microphones also serve as directional microphones. It is important to always adjust the microphone towards the sound source. This applies not only to this model but to all models.
How much does a directional microphone cost?
The simple directional microphones are available for a price starting at €50, rising to €500 (professional models). It is important to look carefully at the target: only with professional directional microphones will you experience higher sound quality.
