VLF (Very Low Frequency) technology used in 220V power line wiretapping circuit breaker refers to the low frequency (very low frequency) range and is a technology mainly used to prevent wiretapping. There are occasional reports in the media that wiretapping was carried out in the United States, Russia, etc., but in most cases, the actual route of wiretapping cannot be found. VLF listening devices can be installed on walls (outlets), ceilings (light fixtures), and anywhere else where 220V power is available, but they cannot be detected. Even if it is detected, there is no suitable alternative to removing the wiretapping device because the wiretapping device can only be discovered when the property is damaged. (If installed in a hotel during an overseas business trip, it cannot be removed.) Also, once installed, the area can be bugged semi-permanently and it can be used remotely. It can also be eavesdropped on, and it is transmitted by modulating it into a digital signal, making it impossible to detect with a wireless detector.
Accordingly, the 220V VLF wiretapping/eavesdropping prevention (blocker) device (KPM-007) can completely prevent (block) power line wiretapping and wiretapping with simple installation.
