It looks for infrared light. This will only detect a small subset of surveillance cameras that actively use infrared light for illumination. There are tons of dome cameras, and such that don't use infrared light.
It's a cool art project.
There was a research paper I found on detecting hidden cameras that emitted high power IR light, and looked for reflective sources. Potentially, you could listen to EM noise, and then introduce visual noise to the environment. It turns out, this is a hard problem to actually solve.
- mikro2nd 13y agoI have read - and I'd love to have this confirmed or refuted - that pretty much all those cameras are tuned somewhat into the IR so that they can still do useful surveillance in low light situations. My ~solution~ hack is to fasten a couple of small IR LEDs into my hat and flood the cameras with lots of lights ;)
- Palomides 13y agocameras are sensitive to IR and usually have a filter to block it, since it it usually unwanted. you'd need extremely and impractically powerful IR lights to do anything useful.
