GSM 4 Gang Extension Lead
 
Mains Powered GSM Socket Lead; with 4G LIVE Audio Listening and Sound Detection
 
The GSM Socket Lead powers small office and home 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 Socket 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 suitable 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 socket lead, so it can be visually examined without raising suspicion. No batteries or recharging are required, providing very long-term mains-powered audio surveillance.
 
4G NETWORK COMPATIBLE
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.
 
SOUND DETECTION FEATURE
This optional feature can be enabled or disabled by sending a coded SMS from a smartphone to the Socket 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 smart way to know when someone has entered your room or if an activity occurs when you are absent without constantly calling in to check.
Note: A 4G SIM card is pre-fitted; however, if you purchase the optional Sound Detection feature, you must top up the associated SIM card with credit (or any SIM card that you use) for this feature to function.  No top-up credit is supplied.
 
RECORD THE AUDIO AS EVIDENCE
If you wish to record the audio you hear through the GSM Socket 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 Socket Lead is a well-made product that will provide additional security for your office, home, workshop, holiday, or caravan home when absent.
