Mains Powered GSM USB Plug; with 4G Audio LIVE Listening and Sound Detection
This functional mains-powered USB Charger GSM Audio Plug and recharge small home and workplace electrical items in a usual manner; however, a professionally fitted GSM SIM card with a sensitive audio microphone will allow you to dial the associated SIM number from a smartphone (or landline) to listen into the room environment clearly. There are no distance limitations; you may call the USB Plug from anywhere worldwide, and the microphone will pick up conversations and sound from approx. 20-25 feet around the Plug, without any humming, cracking or mains interference.
The audio sound is boosted further with superior clarity if you insert a pair of Apple AirPods. You will hear a noticeable difference when listening through a pair of Apple AirPods or other similar brands of earphones. Conversations are easily picked up at distances exceeding 25 feet, depending on the room ambience.
The device can be casually handled as a normal-looking USB Charger Plug. No batteries or recharging are required, thus providing extremely long-term mains-powered audio surveillance.
4G NETWORK COMPATIBLE
Please be aware of poor-quality imitations. In principle, they work, but low prices encourage shoddy workmanship and a poor 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 by engineers who know what they are doing and use real 4G modem technology.
SOUND DETECTION FEATURE
This optional feature can be enabled/disabled by sending a coded text message from a smartphone to the USB Plug. Once enabled, the microphone will actively monitor the room level and call your smartphone when the microphone detects sound above a normal -50 Db threshold. When this feature is enabled, the microphone monitors audio levels in a heightened state and calls your smartphone whenever sound | noise | conversations are detected. This feature is an intelligent way to know when someone has entered your room or activity is taking place when you are absent.
Note: A 4G SIM card is pre-fitted; however, if purchasing the optional Sound Detection feature, you must top up the associated SIM card with credit (or any SIM card 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 USB Plug, consider the iPhone / Smartphone Mobile Call Recorder. This clever device uses Bluetooth to sync with any Bluetooth 3.0 compatible modern smartphone so that the conversation you hear through the USB Plug's microphone can be recorded onto the Call Recorder device.
The Call Recorder's primary function is to record both sides of a mobile phone call. It works equally well with the GSM USB Charger Plug. The Call Recorder also works as a standalone digital voice recorder should you wish to use it as a further evidence-gathering tool.
The iPhone / Smartphone Recorder can be optionally purchased from the menu above.
The GSM Listening USB Plug is a high-quality product that provides additional security to your home | office | workshop | caravan, or holiday home when you are absent.
