An audio surveillance device is found in the Libertad anarchist library in Paris, France. The device is hidden inside the printer-copier of the library. It is composed of two microphones, an antenna, a transformer, a battery, a small box containing an electronic card, a 64 GB SD card and a SIM card from the cell phone provider Orange. According to the communique which announced the discovery of the device, it is a surveillance device of model RB800 marketed by the italian company Innova.
Analysis of the SD card revealed that :
[list]
[*]The device was equipped with a 'voice activation' function, i.e. it only activated when its microphone picked up a sufficiently high sound level. In the month and a half prior to its discovery, it was activated 2,061 times, with a minimum activation duration of 58 seconds, a maximum duration of 12 hours and an average duration of 10 minutes.
[*]When the device was 'activated' by the sound level, it transmitted data over the telephone network (presumably the audio data captured by its microphone), generally at a rate of a few KB/s, with peaks of 100 KB/s.
[*]The temperature of the device varied between 14°C and 50°C, with an average of 22°C. Its temperature rose sharply when it was transmitting data.
