Good lighting is essential. Look in a TV studio of any kind and the most prevalent equipment you will see is the multitude of lights.
Good audio (mic placement) is also very important – use decent mics on boom poles or wireless lav’s if you can.
A tripod is also important, as is a teleprompter and talent that knows how to both run it and read from it (both sides of the camera).
I think the camera is the least important piece of the puzzle as even a good consumer model will yield decent results.
