I have a warehouse that has occasional trespass issues. There are several doors and possible entrances. Only the bottom floor is really secure. The other 4 stories have no product, but the doors and windows are OLD, so old that we have difficulty getting them all to close and lock. Trespassers generally climb a fire escape and enter via the roof and one of the upper 4 floors. I have some cameras on the main floor with a wide angle to review warehouse activities, not for trespass ID. My only real pinch point is the stairway. The upper floors & stairwells are unlit. I'm thinking about putting a camera at the bottom of the stairs, lookup up. I'd add a few lights to get a decent image. Sounds simple, but I've never seen an install like this, so I'm concerned that I've overlooked something.
These guys wear hoodies so I want a low angle on them as they come down the stairs, hopeful I get a good shot of their face.
