What's wrong with the image?
All the lights are on and no one is home.
This is a massive corporate campus on a Saturday morning with about 6 cleaning personnel on site, yet all the lights were on. It makes you wonder if they ever turn off. Maybe they're controlled by a panel with a timer. Maybe not. What a waste.
The use of occupancy sensors can turn these lights on when people are present, and either dim or turn them off when no one is around. Pretty simple. Lighting a space without an observer is like using money as kindling to burn a tire in the front yard - well, almost. Grace your lights with intelligence and feel good about avoiding unnecessary operating costs and emissions.
