E-VMA Audio Recorder, audio listening devices

The E-VMA recorder provides a reliable solution for secret remote reception of audio recordings.
The system includes a miniature voice recorder and a radio receiver that allows full control of the recorder.
The registration process can be activated according to schedules, VOX or via a radio control.
By default, the radio module of the transmitter operates only in reception mode - the data transfer starts on the order of the receiver. This allows extended operation of the device and protects the transmitter from radio-scanning discovery. The data transmission time can also be programmed.

The E-VMA transmitter can operate in five different modes :

• Live audio streaming
• Live audio streaming with simultaneous recording on the transmitter
• Audio recording only, no RF activity
• Audio file transmission
• Standb

The receiver features an LCD screen, which provides a clear interface for controlling the E-VMA system. The operator can request information on the status of all transmitters in the coverage area and select any of them to download records or start the live stream.
The receiver is equipped with an audio output for connecting headphones for listening to the recordings right from the receiver. In addition, transmitter settings can be remotely changed from the receiver.
The downloaded audio files are stored on the micro SD card.
