Small size and great sound quality are the chief assets of the spy bug. A built-in microphone captures sounds within 10-12 meters range. Additionally, an amplifier makes sure that the eavesdropped conversations (even the quiet ones) are clearly audible and noise-free. For live listening in on microphone feed, we recommend a range of receivers available in our shop. The signal transmitted by the bug has a 500 meters range, but please note that high-density housing might reduce it to 200-300 meters.

The device operates within 430-440 MHz frequency band and is quartz stabilized so you do not need to worry that the device will detune during using. Additionally, frequency range differs from the one used in standard radio receivers. Thus, there is no danger that unauthorized persons will be able to hear our transmission.

The appliance is also equipped with very strong neodymium magnet, which allows to attach the bug to any metal surface. It is able to bear weight 1300 times greater than its own mass, which guarantees safety of use.

The spy bug is dedicated for investigators who use similar devices in their everyday work, and for those who want to maintain control over their workplace, or house or install the bug in a car.
