However, without the sensor operating, the lights didn’t come on, so I was looking at a dim corridor which would turn pitch black once the door closed. Infrared vision would help some, but I’d still have to go slow. As soon as I started walking, though, lights came on. Motion sensors. Hopefully all they did was control the lighting. With a sigh, I accepted that I simply wasn’t going to be able to plan for and control everything. As usual, winging it would form a large percentage of my strategy.
