Camera Inspections
Unmanned camera inspections can include the use of manually or power propelled systems equipped with still, real-time and recorded video, and/or closed circuit television (CCTV) cameras. Camera inspections are beneficial because manned entry is not required, small diameter conduit can be inspected, the recording can be compared to previous recodings, and an engineer can perform an off-site evaluation. Hiring an experienced camera operator is important because it can be easy to overlook deficiencies within the conduit.
Manned Entry (>36 inch diameter conduit)
Manned entry is beneficial because it allows for a detailed evaluation of the conduit. Inspectors can usually see deficiencies in the conduit easier with his or her own eyes than with a camera. Appropriate safety precautions must be taken before entering the pipe.
