In this paper, the effectiveness of implementing DSP algorithms necessary to realize the fact of glass breaking in a controlled room is considered. In the course of the research, existing schemes for constructing glassbreak detectors used in existing fire and security alarm systems are analyzed. The possibility of constructing digital filtering algorithms on microcontrollers STM32F4XX of medium degree of integration is investigated. Studies have shown the fundamental possibility of implementing DSP algorithms necessary to detect the fact of glass breaking on STM32F4XX microcontrollers in real time.

Keywords: digital signal processing, burglar alarm system, glass break detector, digital filter, finite impulse response, microcontroller performance.
