This digital audio
recorder is identical in size to modern bank card, comfortable for covert audio recording. There are no buttons and connectors on the body and it has an hidden indication of operating.
The battery operates up to 24 hours in record mode and up to 1500 hours in standby mode. The
recording is of high quality also in noisy environments. The card recorder has a wide dynamic range of recorded signals and high level of data protection. Nobody other than the owner has access to stored data secured by a password.
Time and quality settings are easily adjustable via user-friendly software. All recorded audio data are identified by a date and time stamp.
The micro recorder involves the voice-activated recording system (VAS) andň it has the timer-controlled start/stop of the recording. The user can set up two timers: non-recurring and quotidian. Quotidian timer, once set, will start and stop the recording at specified times every day. Non-recurring timer, once set, will start and stop the recording at a specified date and time. The recording will go on uninterrupted, provided the device has enough free memory and enough battery charge.
The device supports looped recording mode. When this mode is set, the device continues the recording even the free memory is out overwriting the earliest files with the latest audio data. The files being written before activation of this mode remain intact.
The files can be protected trough password protection and ID number that can be digitally signed to every audio file.
The card recorder has a built-in free memory and battery charge LED indicator. Just pressing the ‘gold’ contacts of the recorder you can easily estimate battery charge and free memory capacity.
