This GSM Spy Bug is a special system created for audio surveillance. The GSM Spy Bug uses regular mobile phone SIM services. It is very small and has splicing layer so that it will cling to any surface. It has built-in microphone that can pick up things from a great distance.

They run generally about 24 hours and have a stand by feature up to 15 days. They can capture up to 2-3 hours of data (if you call on it from cell phone with a Dictaphone). Other types can work much longer, but are also more expensive. The GSM Spy Bug is just right for the average person’s needs.
