5.2.4 监视目标有不同的摄取要求时，其镜头类型的选择宜符合下列规定：
1 监视固定目标时，宜采用定焦镜头；
2 需要监视目标全景并兼有目标图像局部细节时，宜采用变焦镜头；
3 监视目标照度恒定或变化较小时，宜采用手动可变光圈镜头；
4 监视目标环境照度变化范围高低相差100倍以上或昼夜使用的摄像机，应采用自动光圈镜头；
5 监视目标视距较大时，宜采用长焦距镜头；
6 监视目标视距较小且视场角较大时，宜采用广角镜头；
7 在高温、热辐射强、粉尘大的场合，宜采用针孔镜头。
5.2.5 变焦距镜头，其变焦和聚焦响应速度应与移动目标的活动速度以及云台的移动速度相适应。
5.2.6 云台的选择应满足生产工艺对监视目标的要求，且应符合下列规定：
1 监视固定目标时，摄像机宜采用固定云台；
2 监视多场景动态目标时，摄像机应采用电动云台；
3 云台的标称承载值应大于或等于安装负载值的1.2倍；
4 云台转动停止时应具有自锁性能。
