A resilient, flexible video push cable is coiled in a stack of coils inside an annular portion of a non-rotating cable storage drum. A video camera head is electro-mechanically connected to a distal end of the push cable. A display is connected to a system interconnect cable which is in turn connected to a proximal end of the push cable. While the drum is held stationary, the push cable can be unwound from its main annular portion and the camera head pushed down a length of pipe. This unwinding of the push cable is facilitated by routing it through a centrally located frusto-conical guide portion of the drum. The video camera head can be pulled out of the pipe, and the push cable can be manually re-inserted through the guide portion to facilitate re-forming of the stack of coils within the main annular portion of the drum.
