> Each surveillance technology in our field guide includes the following categories to help you “spot” surveillance technology in the wild
One shouldn't trust their eyes alone to spot all the hidden cameras that private property owners love to have covering the streets. For example, it took me months to realize that a tenant in my own building has three cameras pointed down from the windows of their unit and can track my every coming and going if they so wish, and that's an environment I have my eyes on every single day.
I have a modified Olympus OM-D E-M5â…ˇ MFT camera body that I picked up on a whim because it came with a bunch of lenses and batteries and other things I wanted to use with my PEN-F, and it turned out to be amazing for spotting hidden surveillance cameras.
The way it works is that the underlying camera sensor can see IR by design, and an IR-cut filter is installed over it to restrict it to the visible spectrum for photography. The mod simply opens up the camera body and removes that part. Surveillance cameras in dark rooms (or at night on the street) then show up as bright spots, because the modified body can see the ring of IR LEDs they use to illuminate dark scenes for night surveillance.
I don't have any surveillance-spotting images to share, because I usually only do that via the viewfinder live preview (because tbh a photo of an all-black room with a single bright IR blob isn't interesting enough to shoot), but for example here is my IR photo of the Windows XP “Bliss” hill (near the Sonoma/Napa border) both as-shot and after channel mixing:

Many cheap camcorders have a "night vision" mode that is just as effective. Probably because those cheap camcorders and cheap security cameras are more or less the same under the hood.
I've rented modified cameras for using to shoot the night sky multiple times. Without fail, the weather for the dark sky that I've rented gear has been shite overcast, rainy, and one time even flooded the location. It has been a waste of money every. single. time.
One day, I'll actually get to use a modified camera body for purpose I just know it
