Digital Mini Audio Transmitters is a digital encrypted miniature audio transmission system. These listening devices are designed to transmit acoustic data via radio channel with digital encoding. Thanks to an encryption, any risk of unauthorized interception of the transmitted informations is virtually eliminated. Due to its tiny size the transmitters can be concealed in various items. Transmitted signal can be received by specially designed digital receiver with built-in decoder only; the detection of these Digital Bugs is extremely difficult. Due to the modulation process interception without a special decoder is very difficult. |
