Listen and record your room and vehicle environment in real-time.
Clearly listen and record the audio through solid brick walls.
Audio Listening Equipment
This category showcases a range of self-contained, portable battery powered, and mains powered secret audio surveillance solutions for use in almost any room environment.
Covert audio listening devices have evolved considerably over the years, the most popular method of listening from a distance was via UHF technology (Ultra High Frequency) which is transmitting crystal controlled signals from audio device to a hand held receiver some short distance away. The upshot of such equipment is the extremely small size and exceptional listening quality, however, a broadcasting license is mandatory to operate.
This forced the technology to move forward and utilise a newer, better form of eavesdropping transmission compliments of the GSM networks. To the present day, the reliable form of audio monitoring is using GSM based, spy listening technology whereby the sound quality is truly excellent and without the range restrictions in comparison to UHF.
Such devices can be found as battery powered GSM bugs for portability, or connected to the mains power supply by way of adapter plugs, double wall sockets and extension socket leads. The additional benefit of these devices is the full functionality of use too.
Amplified audio listening can also take the form of listen through walls devices that operate in much the same way as a doctor’s stethoscope – with the exception the contact microphone is placed on the wall. Vibration travels through the wall from the other side into clear audio waves allowing you to hear with incredible reception. The audio can also be recorded onto a standard voice recorder and used as evidence.
Audio listening devices are more sophisticated than ever before, while the technology remains easy to use. They can be used in almost any room environment and come in portable, battery powered devices and mains-powered solutions. One of the standout features of these devices is that once placed, you can use them for monitoring and recording no matter where you happen to be in the world.
These devices offer:
- Discreet and reliable real-time listening
- Exceptional audio quality, using the very latest technology
- Simple access to the target room from anywhere in the world
- Voice-activated functions, including alerts and recording
- Extra-long operational lifespans and standby times
Listening devices are most commonly used for collecting evidence, but they can also be used for security and general surveillance purposes. Ultimately, they provide audio access when it isn’t safe, convenient or practically possible to manually monitor a room.
How do listening devices work?
GSM listening bugs work on the same networks as mobile phones, which is what makes them so easy and convenient to use. To listen live, you can simply dial in by calling the SIM card located inside the device. As for the devices themselves, they are cleverly disguised as everyday household objects from plug adaptors to iDock chargers, which are also fully functional.
To make the best use of your time and not waste hours waiting for something to happen, choose a voice-activated device. These devices can send you an alert when voices are detected, so that you can listen in live, and they can also start to record audio when voice detection is activated.
Listening through walls
Thanks to new technology, listening and recording through walls up to 20 inches thick with crystal clear audio clarity is now possible. You can choose from affordable contact devices which convert vibrations into audio or high-spec infrared and laser remote devices that allow you to listen to what’s happening from as much as half a kilometre away.
