(18 U.S.C. § 2511.). There are exceptions to this law, however in general, any conversation that is a person considers to be private in nature is protected by the federal Wiretap Act. If you record someone talking in public in front of several people for example, that would not be considered as private.

When purchasing a spy microphone, there are several criteria that you should keep in mind when deciding which product is best for you. To help make you choice easier, in this section we cover the most important factors you need to consider before buying a spy microphone. We hope this guide you helps you buy the device that is best suited for your needs.
- Intended use
- Sound quality
- Battery life
- Range and coverage
- Shape and size
The first question you should really be asking yourself when buying a spy microphone, is how you to plan to use it. As we mentioned previously, there are many different types and models of spy microphones available on the market, and each of them is designed with a specific function or intended purpose. Therefore, if you want a device for your own personal safety, you might be interested in a spy watch.
On the other hand, if you need to record or monitor conversations in one specific place, you should buy a spy microphone that can remain hidden in that location and go completely unnoticed. Finally, you may only need a microphone for remote listening, or one that also has a record function.
Sound quality is clearly a fundamental aspect when choosing which spy microphone you should buy. To get an indication of the sound quality of a particular device, there are a few different parameters you need to take into account. One of them is the sensitivity, which is the level of electrical voltage the microphone outputs. This gives us an idea of how precisely the device will capture quiet sounds.
Another parameter you should consider is the microphone’s level of noise. This is measured in decibels of sound pressure using the A weighting curve (dBA SPL). A decent level is around 40 dBA SPL. Another important specification is the impedance, which is the amount of AC resistance offered by a microphone depending on its frequency.
Another important factor to consider it the battery life of the microphone. You need to consider how long the device is capable of operating, both when in constant use and when in standby mode. It is important to remember that greater battery life means a larger battery, and therefore a device of larger dimensions.
However, today it is possible to find devices with very small dimensions that offer a battery life of more than twenty hours, which is more than enough for most tasks. Additionally, recharging times are generally quite fast. In fact, some spy microphones can be charged in less than an hour.
Range and coverage
For certain uses, such as recording conversations at a distance or the sound of birds in nature, range is a key aspect. The coverage offered by a particular device will depend on the type of integrated microphone and the technology system it uses. In the case of UHF spy microphones, they usually have a maximum coverage of about 100 yards.
Shape and size
When it comes to spy microphones, size is something that really matters. In general, devices with smaller the dimensions are obviously much more useful. They are easier to hide it, and have less of a chance of being detected. Luckily, these days the dimensions of spy microphones are constantly being reduced, as smaller and smaller units become available.
The shapes and designs of the models available vary greatly. They range from the most typical, concealed in pens, clothes or jewelry, to the more elaborate – such as in computer devices and clocks. Other designs often used are USB sticks, key rings and picture frames.
Most spy microphones connect to the computer via a USB port to transfer their audio files. However, there are devices that are also able to be connected via WiFi or Bluetooth. Devices that work using a SIM card obviously connect to a telephone network.
The applications of spy microphones are becoming more and more varied and best of all, they continue to grow. This means they are therefore becoming more useful, due to the advanced technology integrated into these devices. Today there is a wide variety of different models and designs available on the market.
Spy microphones are becoming increasingly popular and more people are deciding to purchase one for themselves. However, most buyers often do not know what criteria they should follow in order to get something that best suits their needs. Without a doubt, the two main things to consider are the intended use and the quality of the sound the device is capable of delivering.
