The smallest GSM and PCS bug in the world is probably the tiniest GSM and PCS room audio transmitter for commercial use on the market today.

Three different versions are available depending on power supply mode used: battery powered, 12VDC powered and mains powered.

Overall transmitter dimensions excluding battery are incredibly small, measuring 1.8"x1.4"x0.4" - 4.5x3.5x1cm only.

Operation is extremely easy: simply plug in any SIM card then dial the GSM/PCS infinity bug SIM/telephone number from any touchtone in the world: the GSM/PCS infinity bug will automatically answer your call without making any noise or blink/flash and you will be able to listen in to what is actually going on in the room where the GSM/PCS infinity bug is located.

Additional advanced features and programming are also available as the smallest GSM/PCS audio transmitter can operate in passive (described above) as well as in active call mode. The active call mode operation is made possible by a very special voice detection circuit that will have the transmitter to place an outgoing monitoring call to the listening post phone number (either landline or cellular) whenever the unit detects any voice or room audio.

In addition to the above features, the most relevant goodies available with this product are:

1. outgoing call upon motion detection
2. dedicated earphone plug (GSM speakerphone HF)
3. operational status report via SMS messaging
4. extended operating time (up to 3 days with a single battery charge, stand-by time).

Remote programming and reprogramming is also possible as this unit can be totally remote-controlled by a series of SMS commands.

This transmitter is powered by three ordinary 1.5VDC AA-type batteries that allow many days of continuous operating time (stand-by mode).

This model works WORLDWIDE under any GSM-based cellphone network (GSM 900-1800Mhz and PCS1900Mhz US frequency standard). Rechargeable battery and battery charger provided included.
