The VV600 Plus seismic detector is designed to detect attempts to break into vaults and safes. This seismic detector reacts to the characteristic vibration patterns of all breaking-and-entering tools, such as hammers, drills, diamond saws, hydraulic pressure tools and thermal tools like welding torch and thermal lance. It will sense vibrations that occur within a 3 to 14 meter radius of where it is mounted, depending on the material and design of the protected object.
