Unverified广角视野覆盖大但边缘畸变会降低AI识别准确率，120°左右是识别精度与覆盖的平衡点；单摄像头难以覆盖多房间，大面积住宅需多机组网而非追求超广角单机83% similarUnverified视角越广（超120°）边缘畸变越明显、单位面积像素密度越低，看清远处细节能力下降；院子全景选广角，抓拍门口人脸车牌选90°左右窄角+高分辨率81% similarUnverified广角视角越大（如120°以上）覆盖范围广但边缘畸变严重、远处物体变小看不清；监控大门等需辨认细节的场景选90°左右+较高分辨率更实用77% similarUnverified视角选择上，广角(≥110°)适合固定安装俯拍整张婴儿床，窄角带云台适合大房间需追踪；但广角边缘畸变会影响细节判断，看面部表情选云台变焦机型76% similarUnverified客厅/大空间监控优先选云台旋转款（水平350°+垂直100°以上）+镜头广角≥130°，单个即可覆盖全屋；固定广角款需要视觉覆盖角度≥150°才能勉强照顾多角落76% similar
