European Mains Extension Lead; with GSM 4G Audio Listening
 
The GSM 6 Gang European Extension Plug Lead powers small home and office electrical appliances as usual; however, it also contains a highly sensitive and professional audio microphone and a 4G SIM card.  You can call the number from a mobile or landline anytime to listen to the surrounding room environment.  There are no distance limitations; you can call the GSM Extension Lead from anywhere in the world, and the microphone will pick up conversations and sounds from approximately 20-25 feet around the unit.
 
If you use a pair of Apple AirPods, the audio sound is enhanced with higher clarity.  You will notice a pleasing difference between listening on your smartphone and listening through a pair of Apple AirPods.  Conversations can be easily picked up at distances exceeding 25 feet, depending on the room's ambience.  Other brand earphones may be equally as good.
The Listening Extension Gang Lead externally looks like a normal extension lead, so it can be visually examined without raising suspicion.  No batteries or recharging are required, providing very long-term mains-powered audio surveillance.
 
SOUND NOTIFICATION FEATURE
This optional feature can be enabled or disabled by sending a coded SMS from a mobile phone to the Extension Lead.  When enabled, the microphone will monitor the room level and call your mobile phone when it detects sound above an average -50 Db threshold.  This feature is a neat way to know when someone has entered your room or if an activity occurs when you are absent without constantly calling in to check.
 
COMPATIBLE WITH 4G NETWORKS
Be cautious of poor-quality imitations.  While they may work in principle, low prices often lead to shoddy craftsmanship and a limited lifespan.  All our GSM products are professionally built to last without humming, mains interference, or static crackles associated with inferior types.  We only endorse the best audio quality, crafted by engineers who know what they are doing and use real 4G modem technology.
 
Note: A 4G SIM card is pre-fitted; however, you must fit a 4G network SIM card for your country.  If you purchase the optional Sound Detection feature, you must top up the associated SIM card with credit for this feature to work.  No top-up credit is supplied.
 
EVIDENCE RECORD THE AUDIO
If you wish to record the audio you hear through the GSM Extension Lead, consider the iPhone / Smartphone Mobile Call Recorder.  This clever device uses Bluetooth technology to sync with any Bluetooth 3.0 compatible modern smartphone, allowing the conversation you hear through the Socket's microphone to be recorded onto the Call Recorder device.
 
The Call Recorder's primary function is designed to record both sides of a mobile phone call and works equally well for the GSM Socket.  The Call Recorder also functions as a standalone digital voice recorder, should you wish to use it as an additional evidence-gathering tool.
 
The iPhone / Smartphone Recorder can be optionally purchased from the menu above.
 
The GSM Listening Extension Lead is a well-made product that will provide additional security for your indoor premises when absent.
