Listening Devices
Listening devices, be they hidden listening devices or covert listening
devices, are generally used for audio surveillance by means of one-way
communications. A listening device can be a voice activated transmitter or voice
transmitter that starts operating once it detects the sound of a persons voice.
When listening devices are active, they may attach to a surveillance
microphone connected to a surveillance recorder, audio transmitter, or Spy Phone, capturing all that
is said and either storing the conversation, or broadcasting it to those who
need to hear the conversation without being present.
Hidden listening devices can be made into mobile configurations to carry on a
person, while covert listening devices may be built into stationary objects or
left covered so no one would notice them.
Note: If you have a question about a listening device, please Contact
Us before ordering. Our goal is to provide you with the listening device to
meet your expectations.
Also: A listening device can always work longer if it employs a vox or voice
activated function.
