EXIT SIGN HIDDEN AUDIO (GSM-BASED) MONITORING DEVICE
When used in the spy mode, the Exit Sign is called (from anywhere) and will answer immediately without any ringing so it will not alert anyone. The caller can then hear all conversations around the Exit Sign and on ending the call, the unit resumes standby. Just plug and play. This model is conveniently portable. We are using the same technology that we put into our Spy Phones . In the United States the coverage is available through AT&T (now Cingular) or T-Mobil. See the FAQ for more details.
Optional: Sound or Voice-Activation!
* The unit will call YOU when it hears sound or voices (approx. 15ft. or 4.57 meters).
Digital Voice Recorders for permanent evidence storage!
