Listening to a conversation is one of the best ways to gather information. Overhearing a verbal exchange between two people can reveal a lot of important details that can be useful. There are various reasons for spying, like to gather information about a cheating spouse, help in a criminal case, and it can also be fun to spy on friends and play pranks on them.
Most of the spy gadgets and gizmos shown in the action movies are fictitious. There may be very few of them which are actually real. But, using the right kind of device will not only help you bather sensitive information, but also keep you undetected. The following are some of the common listening devices, that can not only be used by professional investigators, but also by anyone with a purpose.
Cell phone Listening Devices
Cell phones are a necessity today, and almost everyone carries one. Hence, it has become very easy to spy using this device. Now, these cell phones come either as a separate equipment or are in-built in a cell phone. To use this device the person who is spying will call on an alternate number which connects to a bug inside the cell phone, and once this happens you can easily listen to the person you are spying on.
These are probably the most popular and the best wireless spying devices. You must have seen it in movies, that the agent leaves a small device in the car and follows them to be able to hear the entire conversation. This small device is known as a bug. A bug can look like a lighter, a wrist watch, clock, etc. The best part about this device is that, you can not only listen to the conversation but you can also record it at the same time. Thereby, giving you the freedom to store the proof. Few of the advance bugs come with specialized recorders, which records voice only when on phone or while talking. Hence, it does not record all that unwanted silence.
Few of the modern spy microphones are much smaller and advanced. Few of these come with super-sensors, which allows them to listen to the minutest of voice vibration with exceptional voice clarity. Apart from this, there are few others which come with instruments that allow you to listen many yards away.
This one falls under the category of wearable-spying devices. The best part about it is that, it doesn't look like one. You may also gift it to the person whom you want to spy on, and then listen to his/her conversations. These have exceptional voice quality because of the microprocessors, which fit into the device, and are long-lasting.
Parabolic Ear Listening Device
It comes in different varieties and shapes, and is one of the most used devices. The sound clarity is noteworthy within permissible limits. The device works in a simple way, you just need to point it at the direction where your suspect is and listen. A few of the devices will let you listen clearly from a distance of few yards to hundreds of meters. There are few devices which allow you to listen sharply from as far as 600 meters.
Apart from this, there are many other products available out there depending upon your purpose. If you're a professional, then you may get professional devices, otherwise, you may indulge in saving a lot by getting a decent and more generic device. So the next time if someone gifts you a watch, make sure that it's not a listening device.
