This recorder fits easily into small spaces thanks to its 31x22x8.5 mm size, making it suitable for discreet placement at home, in the office, or during meetings. Voice activation ensures it only records when there is sound, while circular recording keeps it running by overwriting older files when memory fills.

You can customise how it records using the included PC software. Adjust audio quality, set recording schedules, control voice activation sensitivity, and manage file encryption. With support for multiple compression formats and sampling rates from 5461Hz to 22050Hz, you can balance clarity and storage based on your needs.

Powered by a CR2025 battery, it delivers up to 55 hours of recording, 400 hours on standby, and up to 3200 hours in scheduled sleep mode. This makes it practical for both short sessions and long-term monitoring without constant attention.

Unlike bulkier recorders, this device stays unobtrusive while still giving you full control over how and when audio is captured, stored, and secured.
