An amateurish spy microphone with just 20 dollars?

September 29, 2010 Technology 1 Commento

Nowadays, on the Net you can find instructions for everything, ranging from the recipe for a pasta dish all the way to details for making a homemade bomb.
Therefore, it does not come as a surprise if you happen to find the instructions for making a amateur spy microphone.

At a cost of about $ 20, virtually anyone can be able to build a small laser light spy microphone. This microphone is able, through an invisible infrared laser beam, to detect the slightest vibrations of a door or window, caused by sounds produced by the human voice beyond the wood, metal or glass.

The laser beam is collected by a transistor, and thanks to a small amplifier it is then converted into an audio signal. The process of building up the whole thing is relatively easy and would not take too long.

Obviously though, this is amateur equipment, which at most can be used to spy on your neighbor (possibly with harmless intentions and just for fun!). For professional use, it is definitely advisable to use a completely different kind of equipment, such as a directional microphone.

Based on the same concept, laser directional microphones are capable, if their invisible beam is pointed at the glass of a window, to read vibrations and pick up conversations behind it, up to a distance of over a mile. This kind of equipment for remote listening is recommended for use in completely different situations, for example for police forces gathering evidence, or for private detectives during an investigation.

Obviously, compared to this amateurish spy microphone, these devices have a much higher cost, but the result you can achieve are in a class of their own, and can also be used as evidence during trials.

Directional microphones for remote covert listening

July 16, 2010 Technology 1 Commento

As we said yesterday, possibilities to intercept a suspect’s conversations by law enforcement and detectives are countless, although sometimes one has to cope with a little bit of risk when it’s not possible to use telephone wiretapping and micro bugs.
If you do not have the opportunity to hide in the room next to your subject to pick up his conversations, technology still comes to the rescue, for example thanks to directional microphones.

Directional microphones are microphones with high sensitivity features, and with an operating range which can cover a few tens of meters, up to almost a mile for laser type models. In the first case, one can hide in a car behind a fence to pick up, just to name one, conversations of a drug dealer hidden in a park with his clients.

In case the suspects you want to listen to are taking more precautions and hiding in an apparently safe place like an apartment or hotel room, and there is no safe way to come close, the best solution is a laser microphone. As the name goes, this model uses a laser beal, with an operating range of roughly a mile.

To use it, just point the laser beam at the right angle towards the window behind which your suspects are talking. The laser will now read vibrations in the glass, caused by human voices behind it, will translate them into voices and sounds and transmit them to the detectives, hidden at a safe distance, who can record them and use them as evidence.

There are several possibilities to use directional microphones; we invite you to visit the Endoacustica website to find out and contact our experts.
