No chance for wireless bugging  devices. Conferences often take place in order to discuss future projects, internal affairs or to settle financial details. Some conferences talk is absolutely confidential, and it can cause great damage if it is published e.g. by the press without hindrance and without authorization. The PKI 6705 Conference Guard is able to eliminate all these dangers and therefore has developed this new device. The PKI 6705 Conference Guard is a lightweight, mobile device which can be located anywhere. It is a highly sensitive surveillance-counter to analyze frequencies from 10kHz – 6GHz. Frequency changes or field intensity variations are immediately output acoustically or visually. The required antenna system is located invisibly in the case.
