This article discusses in detail the overall design of the system, as well as the realization of the hardware. The main use of pyroelectric infrared chips for the police to enter the regional induction of the human body, and then the infrared signal processing chip for signal processing, the corresponding output level, the ultimate use of the direct simulation of voice chips voice storage features designed to stabilize the work of a voice recording system cycle.  After the hardware and software system debugging, you can achieve the voice storage and playback signals, and only some small modifications can be applied to voice at stations, district police, the police warehouse, it is important to place the warning, as well as in areas such as intelligent home alarm.
