Listen Through Walls

LISTEN THROUGH WALLS AND ACOUSTIC MICROPHONES

Capturing acoustic audio surveillance through solid structures can present unique challenges but can be crucial in certain situations. When it's essential to understand what's occurring behind closed doors, you'll need dependable and precise equipment.

• Penetrate solid brick walls up to 20 inches thick
• Monitor and document conversations through solid masonry
• Capture high-fidelity audio for evidential purposes

We provide a range of products for diverse solutions, from cost-effective contact microphone recording devices to sophisticated infra-red and laser equipment. These tools enable you to monitor indoor audio precisely from distances up to 500 metres.

HOW DOES ONE LISTEN THROUGH WALLS?

Two primary methods for listening through walls are using a contact microphone or a remote audio capture device, such as infrared or laser technology. A contact microphone affixed to the exterior of a brick wall converts acoustic vibrations from the opposite side (essentially any sound or conversation within the target room) into clear audio, providing a robust evidential recording.

A non-contact device allows for remote listening or monitoring of a room or environment, focusing on a specific location with millimetre-level accuracy.

The critical factor in through-wall listening is the clarity of the audio output. All our devices feature advanced audio filtering functions that eliminate unwanted noise, allowing you to focus on the target audio, such as conversations or telephone calls. These filtering functions also enhance the recording quality, amplifying the desired sounds whilst minimising distractions.

BUYERS GUIDE

Through-wall listening devices are a tech enthusiast's dream gadget. Professionally known as 'Contact Wall Microphones', they can be used for various wall thicknesses depending on the specific device:

• 12 inches
• 20 inches
• 23 inches
• 36 inches

The concept behind such a device is that you can hear occurrences in an adjacent room while remaining in your space. These devices have numerous positive applications.

Here are five potential uses:

• Detect animal pests in the home
• Identify loose pipes or knocking sounds
• Monitor potential domestic disturbances next door and alert authorities if the situation escalates
• Keep tabs on a suspicious lodger's behaviour
• Assess the situation behind a door before entering a premises or room—particularly useful for law enforcement

The list of applications is extensive, and individuals will have their reasons for acquiring these devices. It's important to note that it is entirely legal to gather evidence to present to the police if necessary and for submission in a court of law.

Devices Under £200

Entry-level devices can detect audio sounds and conversations through solid walls up to 30 centimetres thick. To operate, position the stethoscope against the wall surface and gently adjust the volume control to suit your hearing sensitivity. This will transform inaudible vibrations into clear audio signals that can be listened to through headphones.

Devices £201 – £500

For a bit more investment, you'll get advanced volume and sensitivity controls, and pricier models might include extras like comfort straps.

Devices Over £500

Top-tier devices offer hands-free capability and often come with wall-mounting equipment. Sound quality is exceptional, featuring the best filtering technology available. Many high-end products use infrared technology, penetrating up to 36 inches of solid brick.

This overview is quite general, as there are many options, each with unique features and applications. The choice depends on your specific needs and budget. Remember, while these devices are powerful tools, using them responsibly and within legal boundaries is crucial.
