A compact spy calculator is something that will never look out of place left on the desk at the office, at home or as an everyday object to produce in-hand at meetings or similar occasions.

Fully Functional Calculator

Maintaining the standard functionality of the calculator is of course of absolute importance, however, the outward appearance of the device must always be preserved as close to the normal standard unit as possible. Here the installation of the recording system within has not had any detrimental effect on either of these considerations. The donor calculator unit is a Canon 10 digit display device with enough standard functionality for everyday calculation requirements and an inbuilt solar panel to negate the need to change the battery regularly. Compact enough to carry around with you in your bag or briefcase ready for swift deployment.

Voice Activated Recording – Exceptional Battery Life

The sensitive microphone is discreetly positioned on the side of the calculator where a 1mm hole has been drilled to allow sounds into the internal microphone. A listening radius of up to 10 metres is easily achievable, especially in a quiet environment. The high-quality voice activated audio recording system is completely concealed within the body of the unit. This is powered by a separate lithium rechargeable battery that can, after a full charge, provide sufficient power for up to 75 days standby time and/or a straight recording time of over 72 hours. Because the recording unit is voice (sound) activated the operating time will invariably be a combination of these two quoted figures. As a result, if the spy calculator was deployed in a room where there was noise for a few hours per day, then the battery would actually be able to keep the audio recorder running for weeks before needing a recharge.

Large Recording Memory – Auto File Storage

The recorded sound files are automatically stored on the internal flash memory system that has a capacity of up to 288 hours of recorded audio. On each occasion that the unit makes a sound activated recording, the event is recorded to a separate audio file in the device memory. This makes navigating between different recording events a far simpler task. The recording memory can catalog up to 9999 separate recording events (which may not use the full memory capacity). Each time the device’s microphone picks up a sound, a recording will start and will stop and save the file when there is no noise for at least a minute.

Time/Date Stamp – Adjustable Sensitivity/Quality

This updated unit now has a time and date reference for each recorded file, which is important to identify when something actually occurred. In addition, through the included software on the device memory it is now possible to alter the sensitivity to suit the deployment environment of the unit and there is also an option to increase the quality of the recorded file, albeit the increase in quality will mean a reduction in memory storage capacity from 288hours to 144 hours. It should be noted that the operating system, of course, cannot distinguish between a human voice, sound from a TV or other noises in the environment and so will record all of them as they occur.

Very Discreet Design and Operation

Starting and stopping recording is achieved through a very discreet a pin operated switch accessible from the outside (pin is supplied).When recording is triggered there is no audible or visual indication whatsoever that audio recording is taking place, so the operation is completely discreet.. Charging the battery and offloading recorded files requires the spy calculator to be opened by unscrewing only four screws (screwdriver supplied). This is a very simple operation and takes a matter of minutes. Because everything is hidden within the calculator recorder gives nothing away and can still be used without arousing any suspicion.

Is the device silent and discreet in operation?

Yes, the device is digital and there are no moving parts or sound alerts that would alert attention in any way.

Are there any lights that would indicate that the device is recording?

No, there are no external lights or other indicators that the device is recording..

Do the recordings have a time and date stamp?

Yes, each time the device makes a separate sound recording a time/date reference is added to the file name, so when their is no sound the recording stops, then when there is more noise/sound a fresh time/dated file is started.

Will the recorder still record if it is hidden away from view?

The unit is designed so as to be completely discreet when left in view, however if hidden away the recorder will still pick up sounds from the environment, although if it is heavily buried out of site, the microphone effectiveness may be reduced.

How can the recordings be played back?

Recordings can be played back through computer speakers by plugging into the USB port of a Windows or Mac computer using the supplied connection cable. No special software is needed.

Can the voice activation feature be switched off?

No, the Calculator Recorder is always set to voice activated recording. There is no straight record option.

Does the device record one big long file with no breaks or does it recorder numerous shorter recording files?

The recorder will record a new file each time the microphone picks up enough sound to start the recording process and then ends the file when the sounds, voices, etc. have stopped.

Will the Calculator still have the ability to make normal calculations?

Yes, the standard functionality of the Calculator is retained. There will be no difference to the standard version in this respect

You will need the following to use this equipment:

  • A suitable screwdriver (philips style is preferable) to open up the device giving access to the charging port inside.
  • A computer with speakers attached if wishing to playback recordings through your PC or Laptop
  • A media player on the computer for playback of audio files. It maybe worthwhile downloading a free media player. We use VLC Media Player at Spy Equipment UK
