4G Bug Remote Audio Monitoring Device

This compact 4G bug measuring only 40 x 30 x 12 mm is a discreet and reliable remote audio monitoring device designed for clear live listening over the mobile network. Small enough to be hidden easily, it can be left in a car or room

When you dial into the bug from any location in the world you will be able to silently listen into any conversations taking place within the same room. The compact black casing helps keep the unit unobtrusive, while the straightforward design makes it easy to set up and use. Ideal for those looking for a small, portable, and easy-to-operate listening device, this 4G bug combines discreet appearance with practical performance.

 4G Connectivity

With 2G mobile networks being progressively phased out across Europe and scheduled for closure in the UK in the coming years, choosing a 4G-compatible listening device is becoming increasingly important.

Unlike older GSM listening devices that rely exclusively on 2G technology, the GSMEB operates using modern 4G LTE connectivity, helping to provide continued usability as mobile networks evolve.

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.

Rechargeable Battery – Up to 3 days Standby

The built-in rechargeable lithium-ion battery provides up to 3 days of standby operation, depending on mobile signal strength, network conditions and usage.
