The real-time images provided by an on-site camera let you view what your target looks like.
The real-time images provided by an on-site camera let you view, along with other measurement data, what your target looks like at that exact moment. In this way, you can combine visual observations with automatic measurement data without the need to actually visit the site.
In some situations, the camera image can also provide explanations for changes in other measurement data if something extraordinary has happened at the site, which can be detected visually. At water sites, using a real-time camera image lets you see, for example, whether the riverbed is frozen, whether there is water in the riverbed during high water, or whether it is flooded.
