Glasstrek’s innovative Model 456 incorporates state of-the-art audio frequency glass break detection and infra-sound impact analysis in its full spectrum.
Model 456 can simultaneously recognize the low frequency signal generated when pressure is applied to glass surfaces in protected areas, as well as the characteristic sound created when glass is broken. The result of this dual analysis is virtually “false alarm free” glass break detection. Combine bilevel analysis with sensitivity adjustment and you’ve got Glasstrek 456, the most advanced glass break detector available on today’s security market.
