Digital Wireless Doorbells (433.92MHz)
Core Technology
Digital doorbells use learning code technology operating at 433.92MHz frequency. This advanced system employs microprocessor-based signal processing for superior performance.
Key Features:
- Operating Range: 100-120 meters in open air
- Interference Resistance: Excellent – learning codes prevent cross-interference
- Volume Control: Adjustable Low/Middle/High settings

Non-Digital Wireless Doorbells (315MHz)
Technical Foundation
Non-digital systems use traditional crystal oscillator technology at 315MHz. These employ simpler analog circuits for straightforward signal transmission.
Characteristics:
- Operating Range: 80-100 meters typical
- Audio: Standard 36 dual-tone melodies
- Reliability: Proven technology with fewer components
