Listen Through Walls Devices

How to listen through walls

The voice in the room vibrates the walls, ceiling and floor. A sensor similar to a medical stethoscope captures these vibrations, electronics amplify them and you hear the conversation in the headphones. You adjust the volume and sensitivity with a knob. The devices work through concrete, brick, wood, metal and glass.

What to consider when choosing

• Amplification - the thicker the wall, the more amplification you will need.
• Recording - if you want to save audio, choose a model with a recorder.
• Power supply - built-in battery charged via USB or replaceable batteries.
• Probes - a long probe will pick up sound even from cavities in the wall or behind doors.

Use a listening device legally

You may use a listening device to protect your own property and in your own premises. Recording or eavesdropping on someone else's conversations without permission is against the law and may even be a criminal offense. If you suspect that someone is eavesdropping on you, a bug detector can help.

You can find other types among our spy listening devices or remote listening devices.
