Wireless Baby Monitor Solution (with SI24R1 Selection)

11/04/2025

Introduction

With advancing technology, parents demand heightened baby monitoring. Smart baby monitors provide real-time activity tracking from anywhere at home. This high-performance solution uses the SI24R1 chip and CB2401 power amplifier for superior safety and convenience.

01. System Components

  • Video/Audio Capture: Camera and microphone for real-time signals.

  • Processing: Encoders compress video/audio.

  • Wireless Communication: SI24R1 (2.4 GHz ISM band, low-power, high-rate) + CB2401 amplifier for extended range and reliability.

  • Control: MCU manages operations and data transfer.

  • Display/Alarm: Parent unit receives, displays signals, and alerts on anomalies.

02. Working Principle

The monitor tracks infant video, audio, and environment via a surveillance end (camera/mic) and control end (display/speakers/app). Surveillance captures data, SI24R1 modulates/transmits (amplified by CB2401). Control receives (amplified by CB2401), SI24R1 demodulates, MCU decodes for display. Features two-way talk, parameter monitoring, cry detection alarms.

03. Recommended Chip

SI24R1: Low-power, high-performance 2.4 GHz GFSK/FSK transceiver (up to 2 Mbps). Paired with CB2401 amplifier, enhances range/stability for long-distance transmission. Enables HD video, audio capture, two-way talk, monitoring, and alarms with strong security/privacy.
