ULTRA-MICRO GSM listening device

ULTRA-MICRO GSM eavesdropping device – world's smallest solution for covert surveillance

It doesn't get more discreet: The ULTRA-MICRO GSM eavesdropping device fits in any palm and can be placed almost anywhere inconspicuously. Despite its tiny size, it delivers clear audio transmission in real-time. A call is enough – and you can hear live what's being spoken in the monitored area. Thanks to Voice-Activation , the device even calls you back automatically as soon as a noise or conversation is detected.

For investigative purposes, the module additionally offers a recording function: With a MicroSD card (up to 32 GB), conversations can be conveniently recorded and listened to later on the computer. This makes the ULTRA-MICRO the ideal choice for surveillance, research, and evidence collection in particularly sensitive situations.
