How does the Acustek GEM-CARD RX spy micro recorder work??

The GEM CARD RX voice recorder is configured with specific software that encrypts the files. Without this software, which is accessed by password, the files cannot be played back.

The configuration is very easy and intuitive. Just select the recording quality (high, low or medium) and the mode (continuous recording, sound detection, calendar).

The GEM CARD RX recorder is started with the included remote control. The recordings are stored on the card itself and transmitted in real time so that your partner can listen to them.

What is the difference between the Acustek GEM CARD RX mini recorder and the GEM CARD RX recorder??

Both recorders are software-configured and have AES-256 encryption systems so that no one else can listen to the recordings. The only differences between the GEM CARD RX spy recorder and the GEM CARD RX is that it is started by a remote control (the GEM CARD by magnet) and that it transmits the conversations in real time up to 150 meters away.
