Unverified85% confidenceDecision RuleTime unknown
虹膜识别门锁的误识率(FAR)应≤0.0001%（百万分之一），且拒识率(FRR)≤1%，才能兼顾安全与日常体验；FAR是核心安全指标，远优于指纹锁的0.002%

Unverified识别精度看误识率(FAR)与拒识率(FRR)，安防级门禁应选FAR≤0.001%(万分之一以下)、FRR≤1%的设备；FAR只标注1%的多为消费级，防尾随和冒用能力不足86% similarUnverified虹膜识别精度高但成本和维护复杂度远高于指纹，普通家庭安防需求下指纹+密码组合已足够，虹膜锁的溢价主要来自安全等级而非日常便利性69% similarUnverified感应距离并非越大越好：家用一般5-10mm感应距离足够贴近导线检测，声称隔厚墙远距离感应的产品往往灵敏度虚高、误报率上升，日常验电优先选灵敏度可调而非盲目追求超远感应61% similarUnverified频闪判断认准IEEE PAR1789'豁免级'或'无风险'标注，用手机慢动作/高帧率拍摄灯面无滚动条纹可初步验证，波动深度应<5%59% similarUnverified精度越高的计量芯片（如带独立计量IC）成本越高，普通用户日常监测用±2%精度已足够；仅电费核算、光伏结算等场景才需追求±1%以内59% similar
