charlie street   March 26, 2019

Listening devices are an excellent way to collect evidence and monitor a variety of situations. Audio spy products can also get the edge over video surveillance as they are a lot more discreet to use and therefore less thought and planning needs to be put into their usage.

Furthermore, their adaptability and versatility make them the ideal solution for both personal and professional use. This article looks to breakdown five of Spy Equipment UK’s best-selling hidden audio recording devices, to help you make a more informed purchase.

1. Enduro Black Box Recorder

Introducing one of our best-selling products, the Enduro Black Box Recorder. This is the ideal hidden audio & voice recording device for a number of reasons, including:

  • Its discreet, inconspicuous design
  • Its small, pocket-size, which makes it perfect to use on-the-go, or to hide in smaller, undetectable places
  • Ideal for long term deployment, especially within a car or other vehicle
  • Its voice activation capabilities mean that when there is no sound in the vicinity of the device, it will save memory space
  • Conserves battery life extremely well – the listening device can remain in standby mode for 166 days

This recorder is also highly versatile as it is compatible with both Windows and Mac computers. Additionally, the sensitivity of the microphone gives it a ten-metre radius.
