GBD 20
GBD 20 is digital glass break detector, suitable for use in premises where intrusion through windows or glass – case is probable. The working algorithm of GBD 20 is based on methods of digital signal processing.
Spectral analysis is carried out together with analysis of the amplitude and the breaking process development to ensure error – free detection.
GBD 20 recognizes breaking of 4 types of glass.
