Here you will find a wide range of listening devices, both covert and overt but with a difference.

 

The advanced devices within this section will not only allow you to remotely listen into the surroundings where the device has been location but will also send you an alert  via SMS (text message) and / or a phone call, if any sound is detected near the device and / or even if the device is moved. This provides the option of you being able to call the device to listen into the surrounding sound when it really matters i.e. when there is activity at the target location.
