User Insights & Application Scenarios:

Traditional smart doorbells mostly rely on Passive Infrared (PIR) sensors to detect human presence at the door. However, this approach has notable limitations. PIR sensors are highly susceptible to temperature fluctuations. In hot summer conditions, their monitoring range diminishes, while in winter, their sensitivity drops due to the insulating effects of heavy clothing. In addition, PIR sensors lack distance sensing capabilities and leading to frequent false wake-ups by hot wind. Their reliance on Fresnel lenses also compromises the product’s design aesthetics. Users are looking for a smart doorbell solution that accurately detects people at the door, is unaffected by temperature changes, reduces false triggers, extends battery life, and maintains a clean, modern appearance.

mmWave Radar For Smart Doorbell:

mmWave radar enables high-precision human presence detection and accurately identifies movement at the door without the need for Fresnel lenses. This technology remains stable across varying temperatures, effectively reducing false triggers and unnecessary activation. As a result, power consumption is significantly lowered, and battery life is extended.
