Voice Activated Calculator
No one would guess that this totally working desk best calculator hides a secret. It is an perfect device for any private detective or private investigator in corporate or personal investigations as it wouldn't arouse suspicion, as a calculator is frequent place in any home or office. There is no visible indication that this is anything but a calculator as the voice recording system is hidden inside.
The calculator recorder uses an SD card, up to 32GB, which can store 570 hours of recording, and is battery powered, giving about 12 hours of sound activated recordings. The back of the calculator has to be removed, by the private investigator or private detective, to access these and to operate the start/stop control. The use of an SD card reader enables the private detective’s or private investigator’s evidence to be retrieved on his or her PC to support the investigation in progress. This is an incredibly efficient device for covert surveillance as no one would suspect their conversations had been getting recorded by such an innocuous item.
