Key Fob Style Voice Recorder

The Key Fob Style Voice Recorder (DR100, LawMate model AR-100) looks like an ordinary car key fob and records clear audio from a built-in microphone with automatic gain control. It is made by LawMate and supported by KJB, and it is used by private investigators, companies, asset protection teams and law enforcement.

Voice-activated or continuous?

Voice-activated mode records only when there is sound, which saves memory and battery over a long day, but it can clip the first word or two when someone starts speaking. Continuous mode captures everything, which is better when a complete record matters. For anything that may be important later, use continuous.

Choosing between our key-fob recorders

The DR100 is the professional choice, with voice activation, AGC and a vibration alert. If you want the simplest possible one-button recorder with more memory, see the Personal Car Key Voice Recorder (AR-300).

Recording law, in plain terms

Arizona is a one-party consent state (A.R.S. § 13-3005): you may record a conversation you are part of, or one where a participant has agreed. Federal law follows the same rule. Several states require every party to agree, including California, Florida, Washington, Illinois, Pennsylvania, Maryland and Massachusetts, and a call between two states can bring the stricter rule into play. Recording a conversation you are not part of, without consent, is a crime almost everywhere. This is general information, not legal advice; if a recording may end up in court, speak to an attorney first.

If the recording may become evidence

Copy the original file off the device as soon as you can, keep that first copy untouched, and work only from duplicates. Note the date, time and place of the recording and who had the device. Do not edit, trim or convert the original. If a recording matters to a case, our digital forensics team can preserve it with a documented chain of custody.
