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.
