Hidden Listening Device

A hidden listening device can sometimes be accidentally found, which is why a concealed listening device can remain masked from discovery. Hidden listening devices can be buried under furniture, above cabinets, while concealable listening devices can be in plain site, yet unrecognizable.

Hidden listening devices, such as a telephone listening device, are hard to notice. Telephone listening devices can be placed by or near a conversation and capture both room and phone conversations. In that instance, a hidden listening device can be placed inside the telephone, or somewhere on the telephone line.
