GSM 4/6 Gang Extension Plug Bug

If you need to monitor a room from a distance and require a device that blends seamlessly with the environment, the GSM 4 or 6 Gang Extension Plug offers an ideal solution. This is particularly useful for situations where discreet observation is crucial, and the device must not attract any attention.

Auto-Answering GSM Bug – Fully Functional Sockets

This mains extension plug integrates a new 4G GSM module and microphone within a standard, fully functional 4 or 6 gang plug extension lead. The GSM Bug is expertly engineered to ensure that the added technology does not compromise the functionality or appearance of the extension lead. The GSM 4/6 Gang Plug can be plugged into any mains socket for continuous power and immediate remote access, which ensures uninterrupted monitoring. The concealed SIM card enables audio monitoring from any telephone. The multi-plug extension operates silently, with no indication of activity, and automatically answers incoming calls, activating a sensitive microphone to capture surrounding audio. This silent operation is vital for maintaining the device’s covert nature.

Blends Into The Environment – Super Sensitive Microphone

The integrated microphone captures normal speech within a 6-metre radius. This ensures effective audio pickup, even when the extension lead is concealed, such as under a desk. The microphone’s sensitivity is calibrated to capture clear audio without picking up excessive background noise. Powered directly from the mains, the unit is ready to receive calls approximately one minute after being connected to a live outlet. All sockets on the power strip remain fully functional, allowing other mains-powered devices to be used without raising suspicion. This maintains the device’s authenticity and prevents it from appearing out of place.

Listen in From Afar

The device can be called from any distance, similar to calling a mobile phone. This provides unparalleled flexibility in monitoring, as the user can be located anywhere with telephone access. No credit is required on the SIM card for listening (international call charges may apply). This eliminates the ongoing cost of topping up the SIM card. However, Pay-as-you-go SIM cards may be deactivated after a period of inactivity. To avoid this, occasional use is recommended. A low-cost contract SIM can prevent disconnection issues, provided the bill is paid. This offers a more reliable, long-term solution for continuous monitoring.

Ideal for Home, Office or Workshop – Changeable Network SIM

The 4 or 6 gang extension GSM unit is an ideal, inconspicuous listening device for homes, offices, or workshops. Its appearance as a standard extension lead allows it to blend seamlessly, especially when used to power other devices or positioned out of sight. The device’s versatility makes it suitable for a wide range of environments and monitoring needs. An operational EE SIM card (pre-pay, no credit) is supplied, but the SIM can be changed to suit budget or network requirements. This allows the user to select the most cost-effective or appropriate network for their specific situation.

Will this work as a standard 4-way or 6-way mains plug adapter?

Yes, it will power devices plugged into it whilst working as a listening device.

How sensitive is the microphone?

The microphone should easily pick up sounds in an 8 metre radius or more in a quiet environment.

Do all of the sockets work or is one blanked off?

All of the sockets work in the normal manner.

Will the GSM bug still work if it is unplugged from the mains power supply?

No, the unit has no back up battery, so you will not be able to listen in when disconnected.

Does it come supplied with a SIM card?

Yes, we normally supply with an EE SIM card, but this can be easily changed over when you receive the GSM unit if required.

Does the GSM Bug make any noise or are there any indication that it is being used as a listening device?

There are no giveaway signs whatsoever.

Will I need credit on the SIM card?

The device does not require credit on the SIM card to receive the call, however it is worth noting that if using a Pay-as-you-go SIM then after a period of time the SIM supplier may cut off the SIM card from the network.

You will need to consider the following to use this equipment:

• You will need a working phone (mobile or landline) to enable you to listen in to the bug.
• If the supplied EE SIM card then you will require a Philips type screwdriver to open up the extension lead to access the SIM card inside.
• This unit is NOT battery powered and must be plugged into a mains power outlet that is switched on.
• The device does not require credit on the SIM card to receive the call, however it is worth noting that if using a Pay-as-you-go SIM then after a period of time the SIM supplier may cut off the SIM card from the network.
