Have you ever grown suspicious about who your spouse is talking to on the phone? Or maybe, you are concerned about your kids. Perhaps you run a business, and you think you are losing your sales because your employees are unethical.

You have a reason why you want to hide a spy recorder. Therefore, it is essential to know how to place the device well. And here are the tips to do it efficiently.

If you suspect something strange, you can hide a piece of a recording device to listen to a conversation. It may not be perfectly legal in some places, but it doesn't mean you cannot do it. The government and police are using them to track down criminals and illegal transactions.

Now, you need to make sure that the spy recorder perfectly fits the task you need it to perform. Take a look at these features that a spy recorder must-have.

1. Battery

The battery determines the operation period of the recorder. For example, if you want to hide it in a place you don't often visit, the device should be able to hold on for a longer time.

The battery life of spy voice recorders varies depending on the style. For instance, a USB flash stick voice recorder can handle a 10-hour of continuous recording. Some have a long recording duration, such as the voice recording pen, which can record for up to 71 hours on a single charge. In high-quality mode, 35 hours is possible, while in low-quality, 17 hours duration is possible.

However, keep in mind that the battery's life goes into standby time and recording time.

2. File Storage 

The essential function of a spy audio recorder is to record communications discreetly and to be able to retrieve and playback the recordings when needed. The most simplistic approach is to use an onboard micro SD card with a storage capacity of at least one gigabyte (GB). (1)

You only want ample file storage if you work in a law firm, government, or the police. That is because they are working on complex cases and need to record indefinitely for documentation.

3. Microphone Quality

The quality of the mic will regulate how audible the recorder’s audio is. Most cheap spy recorders are using non-condensed microphones. So the output is always hard to understand, which means it is useless. It would be wise if the recorder can also absorb high-quality sound. This is important if you are presenting the audio as evidence in court.

In this post, we will only focus on hiding these tiny spy recorders.

Here are the Effective Ways to Hide a Spy Recorder

Concealing an audio recorder takes place in different forms. It may be in the workplace, in the house, even inside your car, or in meetings and interviews, etc.
