A system for inspecting pipelines utilizing a wireless device preferably includes a push cable inspection system, a data display unit, an interface software program and a WiFi transmitter. The push cable inspection system includes a push cable, a distance encoder and a cable reel. A video camera is attached to an end of the push cable. The distance encoder measures the distance traveled by the push cable. The data display unit receives an output from the distance encoder and the video camera. The data display unit overlays a changing numeric distance on the video feed to create a numeric video feed. The numeric video feed is transmitted by the WiFi transmitter to the wireless device. The interface software program is installed on the wireless device. The interface software program receives the numeric video feed from the data display unit and stores the numeric video feed on the wireless device.
