That depends on how much you want to see.
Typically we install cameras in hallways, entry and exit doors, stock rooms, equipment rooms, tool cages, isles, and in wide open areas, 1 camera per 250-1000 sq. feet. Don’t forget to have cameras outdoors too.  Storage yards, driveways, laneways, access roads, parking lots are all key ares to protect as well.
