The mouse spy bug listening device can be activated by calling or sending an SMS to the SIM card number inside the device or by voice activation. It automatically activates when it detects any sound in the area, without any visual, auditory, or vibration signals.
The GSM spy device features a microphone amplifier (able to pick up whispers from several meters away) and a special filter that eliminates noise and interference. The sound is exceptionally clear and pure, and the encoded GSM frequency keeps the line free from external interference. The mouse spy bug listening device is highly suitable for monitoring children and employees, as well as eavesdropping in offices and other work and residential spaces.
