Panasonic proudly introduces System Controller WV-CU650, the total system controller solution for our WJ-HD300 Series of Digital Disk Recorders. The Jog Dial and Shuttle Ring, positioned in the center of the unit, give you quicker, smoother, total control of every search operation and system setting. Plus, it also gives you one-touch access to record, replay, and search functions. The detached joystick allows you to pan, tilt and zoom, seamlessly following the subject you are viewing. Use the larger numeric keypad for direct access to the camera of your choice when using cascade-linked WJ-HD300 Series recorders.
