Please note the appearance of the calcualtor may be subject to changes as we update our portfolio.  This fully functional Canon desk calculator with solar panel is an ideal solution for gathering high quality voice recordings from within the home and office for evidential purposes.  Professionally hand built within the casing of the calculator, the recording mechanism provides a huge 75 days standby time, with a total of 45 hours of actual recording time (per charge).

This Calculator Voice Activated Recorder, as expected from our range of audio surveillance equipment, is a cut above the mustard and can be closely examined and used as a normal functioning digital calculator without revealing its recording capability.


The recording mechanism works independantly from the normal working function of the calculator and is activated by a tiny pin.  Once triggered, audio is easily captured some 25 feet away from where the calculator is placed.


The calculators four (4) GB flash memory is enough to store 144 hours of voice activated MP3 audio encoding @ 64 KBPS for a richer and clearer sound.  To play back audio, the calculator must be opened and the unit connected to a Windows or Mac computer.  No special software is required to play the audio files.

More Information
Can I use the Calculator as normal?

Yes.  Every aspect of the calculator retains its full working functionality.

Is it possible to tell when the calculator is recording?

No.  The recording aspect has no moving parts, external LED's, beeps or any other alerts or indicators that would bring unwanted attention.

Is it possible to record audio whilst using the calculator at the same time?

Yes.  The voice activated recording mechanism operates completely separately to the functionality of the calculator so you (or others) can use the calculator as normal.

How good is the voice recording sensitivity?

The microphone is very high quality, therefore, you can expect conversations to be recorded clearly and without any audio interference.  Audio can be recorded some 25 feet away from where the calculator is placed.  In some cases the microphone can pick up even further depending on the room environment.

Do I need any special software to play the recorded audio?

No.  Each audio file is recorded in MP3 format which is compatible with most media players of a Windows and Mac computer.  We do however, recommend downloading the FREE VLC Player from which supports all kinds of audio & video media.

How long is the standby time and recording time?

A fully charged battery can power the recording aspect for a huge 75 days of standby time, and is capable of recording upon voice activation for a total of 45 hours.  Each recording that is triggered by sound will create a new audio file and the final list will be labeled chronological order 001, 002, 003 etc.

Is it possible to integrate a time & date function?

No. This product does not support a time & date option.
