The RM-1BP Remote Commander controller is a small hard-wired controller designed to work with the HVR-Z1U HDV Camcorder, the HVR-A1U HDV Camcorder, and other Sony camcorders that have a LANC port.

This LANC remote controller can be connected to a tripod's pan handle for convenient control of zoom, focus, and record start/stop. Using the rocker switch to select either slide-wheel zoom or zoom speed, it is easy to perform the sort of slow zooms that are tricky using the camcorder's own controls.
