Our CAME-TV Power Dolly System comes with a Remote, Motor, and Dolly that gives the filmmaker the option to move their camera and tripod wirelessly with the included hand held remote. Create an A-B loop on either a straight track or a curved track, adding dynamic movements to your shots! Kits are available with straight and curved rails and for those that already have rails or want to save on shipping costs, there is a kit available without rails.
