Covert USB Audio Recorder 4GB
The Covert USB Audio Recorder (4GB) can perform two functions: it can be a USB flash drive, with 4GB of internal memory, or a discrete audio recorder, that can record up to 40 hours. The unit comes with 4GB of internal memory (not upgradeable). It can start recording by sliding a switch so you can record audio easily, and discretely, in just seconds. When finished, just connect the unit to your computer’s USB port for playback. The rechargeable battery will be charged each time you connect the unit to the USB drive, and will allow up to 15 hours of continuous use.
