ISN-SM seismic detector monitors objects and surfaces, has a low-profile design, and can be installed effortlessly, even in tight spaces. ISN-SM seismic detectors are designed to monitor safes, night safes, and automatic teller machines.The seismic detector recognizes vibrations caused by explosives and tools such as diamond-tipped drills, mechanical and hydraulic rams, flame cutters, thermal lances, or water jet cutters. The SENSTEC sensor and the digital signal processing monitor a narrow frequency range, thus offering reliable detection. The seismic detector tolerates environmental conditions such as air movement and noise.
