<human>:  Are there spy cameras that are virtually undetectable that a civilian could buy?
<bot>: Hm, good question. I’m not sure if there are any out there that are legal, and definitely would have to be extremely good to avoid getting detected. The people who want to spy on you, and not have their surveillance discovered, usually prefer a physical camera, rather than a camera that’s controlled remotely. There are cameras with very tiny lenses that can be hidden in regular objects, like a picture frame or a clock, so it might be possible to install a camera of some kind that’s inconspicuous.
