Voice Activated Calculator
No one would guess that this fully working desk best calculator hides a secret. It truly 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 widespread place in any home or office. There is no visible indication that this is anything but a calculator as the voice recording technique is hidden inside.
The calculator recorder makes use of an SD card, as much as 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 really is an really powerful device for covert surveillance as no one would suspect their conversations were getting recorded by such an innocuous item.
