Most of them will trigger from reflected IR, which is easy to do with some metallic mylar. Those emergency blankets cut into strips should work like a charm.
That requires an IR source. The glow in the dark might trigger without an external IR source. So depends on the capabilities of the system in question. Some have active IR scene illuminators, some are passive.
It's been a while since I did that sort of thing, but from what I remember: The vast majority of "night vision" cameras are active IR, or sensitive enough that proper reflective surfaces trigger activity if they change a large enough area.
And the type of imagery these searches are looking for, would most likely be fooled by a couple of reflective strips blowing in the wind. Although I might recommend using strips of that reflective stuff on safety vests, that way you'd really "poison the pool".
EDIT:
Don't tape the strips across the street. Hang them nearer the camera so they occupy a larger area of the footage and triggers more easily. Although not on/close to the lens, that will make them notice too soon. You can even just tape a stick on top of the camera that goes up like a fishing rod, with some strands of fishing wire to reflect light in the moisture that condenses(basically a fake spiderweb).
