Baby monitor system with noise filtering

Abstract

A baby monitor system with noise filtering comprises a capture device and a display device, the capture device comprises a detection module, the display device comprises a DSP processor with ENC module and filters; the detection module detects target signals from baby and environmental noise signals to form audio streaming data, and transmits the audio streaming data to the display device in encrypted format; the display device converts the audio streaming data to analog signals and passes the analog signals to input of ENC module of the DSP processor; the ENC module identifies the noise signals and target signals from the analog signals, and activates the filters to filter the noise signals according to frequency bands of noise for attenuating noise sound and to pass the target signals with signal amplification for improving target sound.
