Base Line Data, Inc. performs numerous types of remote video viewing for our clients. We have almost any type of camera system either in-house or at our disposal. These cameras are equipped with articulating heads, crawler capability, and pan and zoom lenses. Some have the capability of crawling down 600 feet and saving these images to a VCR tape. One of the smallest cameras available to our clients has a width of 6mm or .236". If you are looking for a valve that doesn't operate properly or other notable deficiencies, this is an excellent tool for revealing issues at hand.
