Mini Spy Contact Microphone

$49.95 $39.95

Vibrations carry interesting information. Termites or bees in a wall cavity produce vibrations, so do footsteps, voices, and machinery. Even flipping a switch or tapping on a
keyboard produces detectable vibrations if you have the right equipment!


The Mini Spy Contact Microphone, when placed against a hard surface, will translate those vibrations into an electric signal which can be heard and/or recorded and analyzed. Listen directly
with the supplied earbuds, or connect 3.5 mm stereo output jack to your voice recorder to log the information for later review (separate cable required). Or better yet,
connect to your PC (mic input) and view frequency and spectrum data with freely available software such as Audacity. 

Definitely sensitive enough to eavesdrop through walls as it picks up voices with amazing clarity, and maybe to hear the tumblers drop in a high quality combination lock. Could be used in rescue work.

Volume is adjustable. Rechargeable. Runs for about 12 hours per charge, recharges in about 3 hours.
Includes everything you need to get started:
- Mini Spy Contact Microphone Sensor
- AC charger (110-220V, 50/60Hz)
- USB cable for charging from your computer
- Stereo earbuds
