very long audio and video cables

[WellCam]

I need to put a video camera down a dry well to record the condition of the walls. I need to add audio describing the depth/direction the cam is facing. It is 25- 30 ft deep. My quest. is…Can I make an av cable that long to attach my camera to a monitor above ground? Is there a way to record by voice the depth/direction of the cam??? (I can only find short AV cables)

Over 6 feet video cables start to loose high frequencies and that means you loose quality. For long runs consider a video amplifier.
