4/6 Way Extension Voice Recorder

When long-term room audio surveillance requires continuous, uninterrupted operation without reliance on battery power, deploying an extension lead voice recorder provides the ultimate covert solution.

Disguised as a standard UK 4-gang or 6-gang trailing power socket, this versatile listening device blends seamlessly into home, office, workshop, or retail environments.

Because trailing sockets are universally found beneath desks, behind TV cabinets, or alongside office machinery, an extension lead voice recorder sits in plain sight without raising suspicion from staff, visitors, or room occupants.

Fully Operational UK Mains Power Lead & Covert Audio DVR

Unlike portable battery-powered units that require frequent retrieval for recharging, this extension lead voice recorder draws power directly from the 240V AC mains connection.

This delivers unlimited operational lifespan for continuous monitoring over weeks or months.

All 4 or 6 electrical sockets remain fully operational, allowing you to plug in and power lamps, computers, monitors, or chargers in the normal way.

The internal recording mechanism is concealed entirely inside the outer housing and cannot be detected from the outside.

Accessing the internal MicroSD card slot simply requires unplugging the unit and unscrewing the rear housing panel with a standard screwdriver.

Voice-Activated VOX Mode & Evidential Time/Date Stamping

To ensure memory space is used efficiently, the mains-powered voice recorder operates exclusively in Voice-Operated System (VOX) mode.

Equipped with a high-gain internal microphone, the system captures clear conversational speech across a 7-metre (23-foot) radius in quiet room settings.

Recording initiates automatically when sound is detected and safely closes the file when room silence resumes.

Every audio file created by the extension lead voice recorder is watermarked with an accurate time and date stamp for evidential verification.

This precise time reference is invaluable when establishing timelines for corporate investigations, workplace disputes, or domestic safeguarding.

Up to 128 GB MicroSD Storage & Flexible File Playback

Recording storage capacity is determined by your chosen MicroSD card size (supplied with a 32 GB card as standard, storing approximately 336 hours of WAV audio; supports up to 128 GB).

Reviewing captured files is straightforward and requires no specialist software.

Simply remove the MicroSD card and insert it into a PC or Mac using the supplied USB card adapter, or connect directly to a smartphone using an On-The-Go (OTG) reader cable.

The unit operates in total visual and acoustic discretion, emitting zero operational sounds, clicks, or indicator lights while actively recording.

Provided you deploy your surveillance equipment for lawful purposes, the situations that suit using a voice recording device cover a wide range of asset protection, elder care safeguarding, and workplace compliance needs.

Will plugging appliances into the extension lead voice recorder affect its recording capability?

No. This power strip voice recorder is designed so that its internal recording system operates independently on its own fused internal circuit, allowing you to power electrical appliances normally without interfering with microphone sensitivity.

Is the extension lead voice recorder completely silent during operation?

Yes. This device is 100% digital with no mechanical moving parts, buzzers, or relays. It operates in total silence with zero external indicator lights or give-away sounds.

Does the extension lead voice recorder work if unplugged from the mains socket?

No. The extension lead voice recorder relies entirely on continuous 240V AC mains electricity for power and contains no internal battery. Unplugging the lead or switching off the wall socket stops recording immediately.

How do I access and listen to files recorded on the extension lead voice recorder?

Safely unplug the unit from the wall, remove the rear panel screws using a screwdriver, and extract the MicroSD card. Insert the card into the supplied USB adapter and plug it into a PC, Mac, or OTG smartphone adapter to play WAV files.

Can the voice activation feature be turned off to allow continuous recording?

No. The product operates exclusively in Voice-Activated System (VOX) mode to maximize storage efficiency and avoid filling the memory card with long stretches of silent room audio.

How do I set the time and date on this recording device?

Setting the time and date stamp requires connecting the MicroSD card or unit to a computer running Windows OS using the supplied configuration cable and editing the text setup file.

What happens if the 9,999 file limit is reached on the MicroSD card?

In environments with frequent, short bursts of background noise, the internal file index may reach its 9,999 individual file limit before filling the card’s total memory capacity. Once reached, you will need to offload or delete files using a computer.

Can I use a higher capacity MicroSD card in the extension lead voice recorder?

Yes. While the unit comes with a 32 GB MicroSD card as standard (providing approximately 336 hours of storage), it supports MicroSD cards up to 128 GB in capacity.

Will this mains-powered audio recorder pick up voices if hidden behind furniture?

Yes. The internal high-gain microphone captures room audio effectively across a 7-metre radius. However, placing the extension lead behind thick padded cushions or deep inside wooden cabinets will deaden overall microphone pickup.
