To Catch a Pisser
It's a stone wall and floor, so all it took was a few buckets of hot soap and a squeegee to clean the place but still, I'd like to see who did it.
At first I'd calibrated the screen picture of the dark hallway to be bright but then the camera shows some shimmering which the internal alarm interprets as ghosts floating by and these need to be filmed and photographed. After I'd calmed down this screen, no false alarms were sent out and I've been surprised at the level of activity. Before, I hadn't realized that there are actually six homes behind the four doors and every household has people going to work, coming back, ordering food delivery, getting mail and parcels.
The camera has a speaker and microphone so I could even have a conversation with my visitor when I'm not home.
When I'm done watching the staircase, I could move the camera to watch passing ships. Or it could be looking at my coffee machine. It wouldn't be the first.
