Unverified云台摄像头选水平旋转≥350°、垂直≥100°才能实现无死角覆盖；水平旋转不足300°会在墙角留下监控盲区78% similarUnverified运动精度看最小步进角度，优质延时云台应支持0.01°级微步，长焦拍摄或超长时间跨度（数小时以上）时步进过大会造成画面跳格闪烁76% similarUnverified云台机型的水平旋转角度标注355°或340°属正常，因走线预留死区，真正360°需无线/内置电池滑环机型，标称360°者需确认是否有拼接盲区73% similarUnverified云台旋转款（水平355°+垂直可调）适合监控整个房间但存在旋转盲区，人一旦离开画面需等云台转回；固定广角款（水平120°以上）无盲区但视角固定。看娃防坠床优先选大广角固定款而非云台72% similarUnverified云台旋转摄像头(PT/PTZ)的自动追踪功能依赖算法，360°水平旋转机型存在拼接盲区和追踪延迟；固定广角机型(视场角≥130°)反而无死角，看护单一房间选固定广角更可靠72% similar
