This sub-category defines GSM audio listening into mains powered devices. The advantage of GSM products that are powered by the mains provides around the clock 24/7 standby and operation time. This is ideal for extremely long term remote audio surveillance without the need to return on a regular basis but also have less chance of being stumbled upon.
GSM mains powered products can be integrated inside electrical sockets and plugs or within any device powered from an electrical plug like a desk lamp although today's technology does not restrict limitation on the product range and variations possible.
Listening devices are an invaluable tool for monitoring a room, especially when you can’t be there. These clever bugs discretely listen into conversations and other activity, while you’re miles away or even in a different country. They act as your ears in the room, picking up audio for you to listen in to live or record for later review.
With mains-powered listening bugs, you can listen for longer. You don’t have to worry about the battery running out, as these devices are powered by mains electricity. What’s more, they are often disguised as common items plugged into electrical sockets – such as extension leads, phone chargers, adapters and plugs. These devices look perfectly ordinary, but they conceal sophisticated listening technology. However, at first glance or even a closer inspection, no one would ever guess.
How GSM listening bugs work
Many mains-powered listening devices use GSM, which is the Global System for Mobile Communication. This is a digital mobile system commonly used for mobile networks, and GSM listening bugs work in much the same way. Many contain a SIM card, which you can dial into in order to listen into a room or space. It’s easy to call the card and instantly find out what’s happening.
Why use a listening device?
There are lots of occasions when a listening bug could come in very handy. For example:
Provided you use the device for its intended and specific purpose and you keep the recordings for your own personal use, listening bugs are perfectly legal in all of these circumstances.
Mains-powered listening bugs offer many advantages over battery-powered devices. They are the ones to choose if you have any concerns over battery life or you need to listen for longer. If you’re running a long investigation, you need to monitor premises for an extended period or you simply don’t know when audio activity will take place – a GSM mains-powered listening device is the one to choose.
GSM listening bugs have many useful features. When researching the device you wish to buy, make sure to check:
The disguise
One of the most important aspects of your new listening device to get right is the disguise. In situations where you need to listen discretely and without anyone guessing there is a bug in the room, your device needs a believable disguise. Listening bugs come in disguises including phone chargers, extension leads and adapters, many of which are fully functional to add an extra layer to the cover story.
