Add a Power Dolly System from CAME-TV to your kit to perform super-smooth dolly motion shots along the included 1" rails. The system includes a tripod dolly with track wheels, a wireless remote, and a wireless receiver motor. This bundle also includes eight straight 3.3', three curved 3.4', and three curved 2.3' rails. The track wheels are compatible with standard 1" rail and the dolly has a 44 lb maximum load.
The motor is built into one of the track wheel assemblies, and it is powered using a separately available 14.8V V-mount battery using its integrated battery plate. The wireless remote connects to the motor via the 2.4 GHz frequency and provides 10 speed levels and the ability to set A/B endpoints and travel loops. A carry bag is included with the kit and fits all components.
