GSM eavesdropping in a 3-socket extension cord with 4 USB ports

The GSM listening device integrated into a 3-socket power strip with 4 USB ports provides a discreet solution for remotely listening to sounds in a room while maintaining the appearance and full functionality of a standard electrical power strip. The built-in GSM listening device is concealed directly inside the unit. There is no visible external SIM card slot or other element that would normally indicate the presence of a listening module. The power strip features three sockets for electrical appliances and four USB ports, allowing it to be used simultaneously for standard power supply and charging electronic devices. To use the listening function, a compatible SIM card must be inserted and the phone number of the inserted SIM card must then be called. The device answers the call and allows you to remotely listen to sounds in its surroundings. Thanks to the GSM connection, the distance between the user and the device is not limited by a conventional radio transmission range – sufficient coverage by the supported mobile network is the key requirement. A major advantage is the direct power supply from the electrical mains. When the power strip is plugged into an electrical outlet, there is no need to regularly recharge an internal battery, allowing long-term operation. The sensitive microphone can pick up surrounding sounds from a distance of up to approximately 7 metres, depending on the acoustic conditions of the room. The device also supports voice activation and is particularly suitable for situations where long-term operation without regular charging is required.

GSM listening device with remote listening function

The integrated GSM listening device operates via the mobile network. After inserting a compatible SIM card, you can call its phone number and use your mobile phone to listen to sounds picked up by the device’s microphone. You do not need to be in the immediate vicinity of the power strip.

The distance between the user and the listening device is therefore not limited to a few dozen or a few hundred metres, as is the case with conventional radio devices. The main requirement for proper operation is sufficient coverage by a compatible GSM network at the location where the device is used. According to the available specifications, the device supports 850, 900, 1800 and 1900 MHz frequencies.

Sensitive microphone and voice activation

The integrated microphone can pick up surrounding sounds from a distance of up to approximately 7 metres. The actual range and audio clarity depend on the specific environment, room size, background noise, obstacles and the distance between the people speaking and the device.

The GSM module also supports adjustable voice activation. This function allows the device to react to sounds in its surroundings and expands its possible uses according to the user’s specific requirements.

Continuous power supply from the electrical mains

One of the main advantages of this model is its method of power supply. The GSM listening device integrated into the power strip is connected directly to the electrical mains during normal use, meaning its operating time is not limited by the capacity of a conventional battery.

This makes the device suitable for long-term operation. As long as the power strip remains connected to the electrical mains and a sufficient GSM signal is available, the listening device does not need to be regularly disconnected and recharged like portable devices powered exclusively by a rechargeable battery.

Fully functional power strip with 3 sockets and 4 USB ports

The integrated listening device does not interfere with the standard functionality of the power strip. It provides 3 electrical sockets and 4 USB ports, which can be used to connect, power and charge compatible electrical and electronic devices.

This allows the power strip to blend naturally into a home, office or other indoor environment. The USB ports can be used, for example, to charge mobile phones and other electronic devices that support USB power. The combination of a fully functional standard power strip and an integrated GSM module enables long-term operation without requiring a separate power source for the listening device.
