Obtain Adequate Visibility Out Of Your High Definition CCTV Camera And Avoid Data Rejections

摘要

Proper image quality is critical for sewer CCTV (Closed Circuit Television) inspections. The value of sewerrninspections relies on the ability to see defects and make observations along the pipeline. A simple drop of water onrnthe lens, fogginess inside the sewer, or inadequate lighting, are some of the factors that contribute to poor visibility.rnThese factors may adversely affect important engineering decisions pertaining to costly rehabilitation methods.rnHaving a high-definition CCTV camera televising a poorly visible sewer pipeline is comparable to driving arnFormula One racing car running at full speed on a dirt road.rnMunicipalities and contractors invest thousands of dollars in high-definition cameras and personnel, both capable ofrnbeing productive in the work place and reliable for documenting high quality images of defects and observationsrninside pipelines. Sewer inspections carried out using this technology more often than not, provide successful visualrnresults; however, when inspection data is rejected by the owner, there are monetary losses incurred by all parties.rnSimple visibility problems should not be the cause of such rejections. This paper analyzes CCTV visibility problemsrnand possible solutions by presenting two case scenarios.
