William Lamson’s art-project is delightful: a helium balloon artfully positioned so as to blind a CCTV. This could be a lot of fun for real-world shenanigans or for a piece of fiction. Just got to hope for a windless day.”

CCTV vs Helium Baloon

Cool, but in the comments is a much cooler story…

In the UK we have long been playing with ways to disable CCTV. We have had people use climbing equipment to shin up poles and cover them with black plastic bin bags. We have experimented with running up a daisy chain of helium filled mylar balloons on a collar around the post and I even know of one instance when a couple went along to a car in full view of the cameras with one of those cans meant for holding small amounts of petrol, poured it all over a car in the street and stood back laughing and lighting smokes till they heard a siren and diligently started a random act of kindness and washed the car with the water they had poured over it. Street theater still has the best style.

THAT IS AWESOME!
