The Canon Remote Controller RC-V100 is an accessory designed for operating compatible Canon Digital Cinema Cameras and HD Camcorders remotely. It connects directly to the camera's REMOTE terminal via a cable, granting the user control over many of the camera's functions from a distance. A convenient feature is that the remote draws its power directly from the camera, so it doesn't require its own batteries. For specific details on which functions are supported, users need to consult the most current instruction manual for their particular camera model.
