Thermal imaging
对于热成像，团队使用星形Safire 380-HD系统向前查找红外线（FLIR）设备（如下图）。
这是一个完整的高清系统，提供一个陀螺稳定图像，其中嵌入数字视频中的元数据。
The Star SAFIRE 380-HD is fully hardened for fixed-wing and helicopter operations so it can operate continuously in all conditions, even while sitting on the tarmac.
它包括两个主要组件：炮塔FLIR单元（TFU）和通用手动控制器（UHCU）。
观察者用UHCU控制TFU，可以使用安装在TFU中的激光测距仪瞄准故障。
Visual imaging
该团队使用陀螺稳定系统（GSS）来稳定在船上佳能相机上的图像。
The camera itself can be fitted with a variety of lenses depending on what it's being used for.
The 600mm lens (shown in the photograph) allows close-up photography of the infrastructure. It will allow the identification plates of equipment to be read from the helicopter at normal operating altitudes (1000 feet).
300mm镜头对检查线路建筑物和结构更有用。
The 85mm lens is likely to be used for RouteView imagery.
