USA Mains Extension Plug; with 4G GSM Listening Audio
 
The GSM 6 Gang USA Extension Plug powers home and office small electrical appliances as normal; however, it is also fitted with a professional and highly sensitive 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 Plug from anywhere worldwide, and the microphone will pick up sounds and conversations from approximately 20-25 feet around the device.
 
If you use a pair of Apple AirPods, the audio sound is enhanced with higher clarity.  You will notice an uplift in clarity 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 Plug externally looks like an average extension lead, so it can be visually examined without raising suspicion.  No batteries or recharging are required, providing long-term mains-powered sound surveillance.
 
SOUND NOTIFICATION FUNCTION
This optional function can be enabled or disabled by sending a coded SMS from a smartphone to the Extension Plug.  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 good way to know when someone has entered your room or if an activity occurs when you are absent without constantly calling in to check.
 
NETWORK 4G COMPATIBLE
Be cautious of poor-quality imitations.  They may work initially, but low prices often lead to poor craftsmanship and a limited lifespan.  All our GSM products are built professionally and without mains interference, humming or static crackling associated with inferior types.  We only endorse the best sound quality, built by engineers who know what they are doing and use genuine 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 function, you must top up the associated SIM card with credit for this feature to work.  No top-up credit is supplied.
 
CAPTURE AUDIO EVIDENCE
If you wish to record the sound you hear through the GSM Extension Plug, consider the iPhone / Smartphone Mobile Call Recorder.  This smart device uses Bluetooth technology to sync with any modern Bluetooth 3.0 compatible 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 Extension Plug.  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 Plug is a well-designed product that will provide extra security for your home and office when absent.
