Means you have 1 "Live" (manned) camera and 1 remote control camera (no live operator) to cover your event simultaneously. (still using 2 cameras operated by 1 person)

2 cameras give you the advantage of different angles for better point of view and coverage. This will allow your editing to give a "Movie Like" appeal.

In most situations "1 live + 1 remote camera" can be nearly as effective as "2 live cameras" with proper advance planning and placement.
