Having high-quality audio recordings is crucial for many individuals. These include journalists conducting interviews, students recording essential lectures, and those working in the legal profession. With the most extensive array of audio surveillance systems curated in one place, we can provide you with the right equipment for your needs.


While there are many different analog and digital listening devices suitable for various purposes, the USB Power Bank Audio Recorder is optimal for versatility and discretion. It has an extremely long battery life, can record for 336 continuous hours, and can last up to 150 days while in standby/voice activation. It slips into the USB port of any computer to allow you to save your recordings quickly and starts recording with a single flip of a switch. See all Spy Recorders.


While covert video surveillance systems have to hide cameras, listening devices are tiny and have small microphones fitted inside very neatly. These devices are usually so minuscule that they typically go unnoticed. Often, they are disguised to look like everyday objects, like USB drives or pens. This makes them even more discreet and easy to plant.

There are both active and passive listening devices. With active devices, you can listen to crystal-clear audio while it is being recorded. You must upload and listen to the recorded audio with passive devices after completing the recording. An advantage of passive listening devices is that they have long battery life, and their voice activation feature allows them to remain on standby for days.

However, there are many different types of listening devices; some, for example, are designed for capturing cell phone calls or calls on landlines. Simultaneously, others are built into security cameras for video surveillance security.


Listening devices tend to be on the smaller side to go undetected. For example, some of the most discreet, unnoticeable devices are designed to look exactly like a USB Flash Drive.

Check out the Mini Micro Stick, which is only 2.5 x .8 x .5 inches in size, or our LawMate Audio Keychain, which has the dimensions of only 3.0 x 1.25 x 0.563 inches, or the World's Smallest Micro Voice Recorder measuring 1.8 x .24 x .7 inches and one of our favorites the Magnetic Mini Voice Recorder .82 x 1.05 x .38 inches.


Whether you're looking to record audio over WIFI, improve your home security system, or install a CCTV hidden camera, be sure to check out all the different types of devices and microphones available!

Base Stations: Audio base stations are audio surveillance devices with speakers or microphones for one-way or two-way audio.

Voice Activated Recording Device: Voice-activated devices will begin recording once a voice or noise over a certain decibel level is detected. When no voice or noise is detected, it will remain on standby to conserve power and memory.

Outdoor Microphone: Outdoor microphones are designed to pick up sounds from within an outdoor coverage area. They usually can record sound within a few hundred feet of the device and are generally omnidirectional like digital voice recorders. Some outdoor security cameras don't even record audio, so having this, in addition to a night vision-capable video surveillance system, is a great way to secure your home or business.

Private Investigator Work: Private Investigators will require the highest quality, most discreet recording technology. This might include a voice-activated recorder pen with a 16-hour battery and genuine ink for writing or a digital voice recorder watch with a pickup range of 40 feet.

Gather, Store, and Protect Your Information: Individuals working in law enforcement, private detectives, and private persons rely on recording devices to discreetly capture essential audio recordings. If you need to gather and store audio information, Spycentre Security can provide you with all the required equipment. With such a massive range of high-quality products on our website, there is no doubt that the best audio surveillance apparatus is within your grasp.



When it comes to capturing and collecting audio evidence of any sort, you'll want the ease of use of plug-and-play devices. You may not worry about people seeing a recording taking place, but, being the SpyCentre, we feel you will need to remain as covert and discreet as possible.

That's why it helps to know what type of audio collection devices are available, which devices they support, and how to use them without attracting any attention to yourself. So, with that in mind, let's look at a few of our best audio collection accessories currently available.

Android smart devices are remarkable in terms of interoperability with other devices, and, unfortunately, iPhones and iPads cannot utilize the following product. Our Dual Android OTG Cable can be used with either a Micro USB or a USB-C plug to connect with the Android, and at the other end is a USB port where external memory drives, like USBs and audio recorders, can be inserted. Find the information by locating the external drive from the Android storage settings.

Use the free VLC application to listen to audio recordings and then delete files that are not needed to clear up memory for new recordings. For those business people on the go, reporters on a tight schedule, or people without computers, this can be quite a boon to enable viewing important documents or listening to critical recordings right away.

Tables and desks are not always the best places to set down a recorder: they could alert someone that a recording is taking place or get stolen by someone trying to protect themselves from having their words used against them. Recorders placed in drawers or pockets may only get muffled recordings, so keeping them out in the open is best. It may be better to find a way to affix an audio recording device elsewhere, such as under the table or behind a dresser.

Let us introduce the SCOSCHE MagicMount Surface 2, which is precisely the piece of equipment you've been looking for to help you enhance your portable audio collection game. This kit is used frequently with our World's Thinnest Micro Voice Recorder (Voice activated). It can even be used to create body-worn applications or secured installations with some of our cameras, like the Zetta Max Swivel Security Camera Rotatable 180° Lens.

Two small metal plates and two rubberized magnets come with this kit, enabling the most creative covert placements of recorders imaginable. Attach one of the metal plates to your electronic device, be it a recorder, a smartphone, or a camera; this will block any harmful magnetic interference from the magnets. Use the magnet to hold your item to a metal surface, or get the second metal plate and stick it to a non-magnetic surface to place the device there instead.

Be sure to use both plates and the two magnets if your device is heavy! These audio accessories enable uses beyond the standard applications for many of our audio and video recording devices. Take a moment to think about all the ways you could utilize a more compact and low-profile product than wired cameras or wireless security cameras, then look to these audio recorder accessories for any more ideas you may need.
