  • Patent number: 11665321
    Abstract: A pipe inspection system includes a cable storage drum and a housing configured to removably receive and rotatably support the cable storage drum. A push-cable with a plurality of conductors is stored in the cable storage drum. A camera head is connected to a distal end of the push-cable. A slip-ring assembly has first and second mating portions that when mated provide conductive paths between the plurality of conductors at a proximal end of the push-capable and a display device. The first portion of the slip-ring assembly is mounted on the housing and the second portion of the slip-ring assembly is mounted on the removable cable storage drum. The system connection cable joining the inspection system with a display unit is removable and may be replaced with cables compatible with various alternate image display systems.
