Professional and discreet recording

DVR-SD32 micro operational voice recorder in SD memory card

Brilliant in simplicity, with the best technology and useful features of wireless connection, remote configuration setup and downloading via a computer or smartphone gives you great opportunities for discreet evidence recording.

Recordings are stored on the built-in 32 MB memory (can hold more than 12 weeks of recordings). The data can be encrypted with any key of up to 32 characters with the AES256 algorithm. In addition, the card can be formatted as 1 or 2 partitions (hidden or visible, encrypted or unprotected).

Recording can be carried out in continuous mode, with sound activation (the user can set thresholds for recording activation, recording termination and time delay), time-activated (4 schedules with a one-time activation scenario, weekly on working days and holidays) or activated remotely via Bluetooth. The Bluetooth module used provides high-speed data transfer of up to 1 Mbps over a distance of up to 50 meters.

Access to the configuration and recordings is achieved in two ways:

  • via a PC after inserting the card into the reader
  • via an Android device after connecting via Bluetooth (minimum BT 4.0, for real-time audio streaming BT 5.0 required)

The voice recorder is powered by a built-in 13 mAh battery. Energy-efficient technology of the device is characterized by low power consumption - recording time up to 10 h. The device can be powered from the card reader, which gives unlimited operation time. The DVR-SD32 micro recorder is so small that it fits inside an SD memory card - perfect camouflage and ease of use in many situations. Even such a miniature device offers very high quality audio processed by a converter with 24bit resolution and 44 kHz sampling.
