The best way to make sure that you’re never caught off-guard is to have as much information as possible, about the various situations that you may find yourself in. Whether you’re trying to find out if your spouse is cheating on you, or if you simply want the ability to eavesdrop on people without them knowing, listening devices are great tools to have

These are perfectly legal to buy and own, however, it is important to check your local laws in order to determine if you can also use them openly. Furthermore, these are usually used by authorized private investigators and federal agents, therefore not all recordings may be usable in an official capacity, for example, as proof in court.

This having been said, there are several types of long range listening devices and understanding what each of them can do is essential when it comes to getting a piece of equipment that will get the job done.

Buying Guide – Types of Long-Distance Listening Devices

  • Audio probes and wall amplifiers – These usually come in a pair and are useful when having to monitor someone in another room. The probes are usually extremely thin and can be inserted into keyholes or under doors, while the wall amplifiers can be placed on walls in order to hear what is being discussed on the other side;
  • Microphone amplifiers – These are the types of devices that can be seen in spy movies. They resemble satellite dishes with high-quality microphones in the center and can easily amplify the sound of a discussion at a distance of 300 ft. 
  • Long-range microphones – Often used by private investigators, these can pick-up sound from a distance of around 30ft. This type of microphone cannot be used on its own and requires additional equipment, such as a camera;
  • Wireless microphones – The last category of long range listening devices is made up of microphones and audio-enabled cameras that can connect to a WiFi network and allow the owner to tap into their live feed and actively listen to what is being recorded. These are typically extremely small and easy to hide, and can be placed in furniture and decorative objects;

Each of these devices serves a different purpose and has different capabilities. Furthermore, keep in mind that some may require additional equipment, such as microSD cards, headphones, and also that some devices may be dependent on a stable WiFi connection.

Consider how useful each of these devices is for your particular situation and decide on a type of equipment before looking at the various models that are available. This will ensure that you have as much flexibility as you need and that you will be able to monitor your target without being seen or discovered.

Conclusion

Furthermore, keep in mind that there are legal to buy and own anywhere in the world, however, using them is another matter. Do a bit of research and look into what your local laws say regarding surveillance and the ability to monitor other individuals.
