Viewline works in these two modes:
-
Either the CCTV surveyor collects video files from site. One video file per section (a typical section would be from one manhole to the next manhole).
-
The CCTV surveyor uses a system that allows them to record live video, reporting live and saving each video file to the completed section header.
Option 1 is used extensively in the drainage industry, as is option 2. There is no right or wrong or recommended methodology. There are pros and cons for each. Option 2 is good for getting the work completed live, however it might lead to double handling as the work may need to be checked prior to going to the client anyway. Option 1 means some site work, collecting video files and then some office work, reporting on the same.
It is often down to the company’s preference and Viewline caters for both options.
