Calculator Voice Recorder (Voice Activated)
This product is a normal looking, fully-functioning desk calculator which hides a built-in, voice-activated covert audio recording device. This is the ideal unit to leave innocently lying on a table/desk.
The calculator itself is a solar powered Sharp unit, and the internal voice recorder is powered by a separate built-in rechargeable battery. The battery allows for approximately 12 hours of recording time, and 12 hours of life when on standby.
The product holds an SD card, up to a maximum of 32GB. The voice recording system is completely and discretely hidden within the calculator, and the controls are concealed under a panel on the back. This means the device can be operated secretly without arousing any suspicion.
