Professional 4G Remote Audio Monitoring – Listen from Anywhere in the World

Operation couldn't be simpler. Just insert a compatible SIM card, position the device in the required location and call its mobile number from your phone. The device automatically answers, allowing you to hear live audio from its surroundings, wherever you are in the world.

The sensitive microphone can pick up conversations and other sounds from up to 10 metres away, depending on the surrounding environment, without producing any audible ringing tones or alerts.

Purpose-Built for High Performance

Unlike modified mobile phones or basic consumer listening devices, the Eyetek GSMEB is a dedicated 4G audio monitoring system, professionally assembled in our own workshops. Designed with reliability and discretion in mind, it offers straightforward operation without complicated applications, Wi-Fi connections or specialist equipment.

Automatic Sound-Activated Calling

For additional convenience, the device features an automatic sound-activated callback function.

When enabled, the unit can automatically call your designated telephone number when surrounding sound exceeds approximately 45dB.

This allows you to be alerted to activity without having to continuously call the device to check its surroundings.

Future-Ready 4G Connectivity

The device supports both TDD-LTE and FDD-LTE technologies and is designed for use with compatible UK mobile networks, including EE, Vodafone, O2 and Three, subject to SIM compatibility, supported frequency bands and network coverage.
