Unverified夜间与逆光表现主要取决于红外补光和宽动态(WDR)能力，选带主动红外补光+WDR≥100dB的设备；纯依赖可见光摄像头的门禁在夜间或强逆光门口识别率会明显下降88% similarUnverified宽动态范围(WDR)≥100dB且带主动红外补光的设备才能应对逆光和夜间，纯白光补光会造成用户眩目且夜间体验差85% similarUnverified夜间识别能力优先选带850nm或940nm主动红外补光的机型，940nm波长无红光外溢不刺眼，850nm成本低但夜间会有微弱红点。无红外补光的纯可见光摄像头在黑暗环境下检测率会骤降到50%以下81% similarUnverified户外强光监看场景（相机监视器/日间办公）建议亮度≥400nit且优先雾面/防眩光屏，配合内置电池；室内影音娱乐用途200-300nit亮度即够，可选更轻的机型81% similarUnverified户外强光下优先选MIP半反射屏（常亮低功耗）或峰值亮度≥1000nit的AMOLED，普通AMOLED在正午强光反光下几乎看不清地图78% similar
