Wall Socket GSM Listening Device – Dual Gang, Voice Activated, Call-Back

Unlike our plug-in options, this GSM listening device replaces an existing wall socket outright, making it the most permanent and integrated option in the range. Fitted as a genuine BG-style double switched 13A socket, it's built for situations where you want monitoring built into the room itself rather than something that can be unplugged, moved, or noticed sitting in a socket. Because it's a proper fixed installation, it includes hardware the smaller plug-in devices don't: an enhanced microphone and a high-gain antenna, both aimed at giving noticeably better pickup and network reception than a compact adapter can manage.

Once installed, it runs on continuous mains power indefinitely, supports remote audio check-ins via a standard voice SIM, and can place a call-back alert when sound crosses a set threshold. SMS control lets you toggle monitoring features remotely without needing physical access to the socket. This is the option to choose when long-term reliability and stronger audio quality matter more than the flexibility of something you can unplug and relocate, for authorised, lawful installations only, with clear permission from anyone who may be monitored.

Key Features

• Genuine dual-gang wall socket: Fully functional BG-style double switched 13A socket, not just a disguised adapter.
• Enhanced microphone and high-gain antenna: Built for stronger audio pickup and more reliable network reception than a compact plug-in device.
• Voice call alert: Notifies a preset number when sound above a set threshold is detected.
• Remote audio access: Standard voice SIM supports live call-in listening.
• SMS feature control: Toggle monitoring on or off remotely by text.
• Continuous mains power: Built for long-term, always-on installation.
• Quad-band GSM: Covers 850, 900, 1800 and 1900 MHz.

Ideal For

This is the right choice for a permanent, fixed-location installation where signal quality and long-term reliability matter more than the ability to move the device — a property you want continuously monitored over months rather than a short-term or flexible setup. Its enhanced hardware makes it the strongest option in this range for larger rooms or spaces with weaker signal. For authorised, lawful indoor installation only, with clear consent from anyone who may be monitored.
