CCTV Drain Inspection Over the years drains can deteriorate this could be down to poor construction, ground movement, root damage etc. The camera survey will provide us with the most cost effective remedy to your drainage problems. Firstly the camera is inserted into the drainpipe via a manhole. It is then sent along the pipe. As this is happening an operator above ground is watching and recording on video. A report is then provided containing a VHS or DVD recording of the drain, any defects and their location. This can be backed up with a site plan showing the drain's location etc.
