Factors to Consider When Buying

Spy microphones are the kind of products where you cannot compromise on the efficiency of their features, overall performance, and reliability. Therefore, when buying a spy microphone, you should look for some features that must be present in the selected product.

Voice Activation System

There is no point in having a spy microphone that needs you to click several buttons before it can turn ON and start recording. Anybody that identifies such a microphone might be so curious to understand what is contained inside, which might contain some delicate details, that they might not stop until they've found the truth.

Deciding to purchase a voice-activated password-protected microphone can conserve you the embarrassment and protect your cover. There are numerous such microphones in the market that you can choose from however selecting one that is user-friendly and easy-to-use is imperative. You also need to make sure that you know and understand the security system of your selected microphone like the back of your fingers so you don't get locked out of your recorder and its contents.

Recording Capability

Any spy microphone that cannot record for a long time is pointless to have. Take meetings, calls on a computer, and conversations for example. All these can potentially stretch into hours and if your microphone stops in the middle of recording, either due to a lack of storage or because its hours limit is reached, it can be extremely frustrating because another such opportunity may not come back again where you can record like that.

Therefore, when buying a spy microphone, always make sure to check its recording hours capability. Some very good ones can record for a total of 600+ hours.

Memory Capacity

If you are looking to record conversations, meetings, lectures, and whatnot, anything that can be long and needs to be done discreetly will require large storage capacity. In some cases, you may even want to plant the microphone somewhere and leave it for hours so that everything can be recorded throughout the duration. For this, too, you will need at least 16 gigabytes of storage capacity and a considerable recording hours limit to make it happen.

On the other hand, if you just want to use the microphone for prank purposes or to record your passing thoughts without letting anyone know, then you might not need large storage. Any storage will work for you in this case because you will not be keeping the files forever in the microphone as they can be shifted to your computer and that will clear up space too.

However, if you are unsure of how you are going to use the microphone then, you should just go for the one with the maximum storage capacity. Besides, you can utilize the extra space in the future for other purposes, so it’s not like the extra bucks spent will be wasted.

Shape and Size

The size and the shape of your spy microphone can significantly affect how successfully you would be at hiding it and the ease of use in general. If you have a large microphone hiding in your pocket like a bulging smartphone, that will destroy the purpose of it being hidden. Therefore, small-sized recorders are the way to go as they’re less likely to be detected, easy to move around without anyone noticing, and possible to plant somewhere to record all the audios and sounds there.

Also, the shape of the voice recorder should be kept in mind as well. Spy voice recorders that are integrated inside objects of everyday use are nearly impossible to detect. Take for example a bracelet, pen, ring, etc. In case of sensitive meetings where recorders might be forbidden, a safe pen geared up with voice recording technology can be useful beyond measures.
