Until someone develops hidden cameras with AI that will be auto turned on couple of hours later after detecting presence at that time a scan was already performed and nothing was found.....
this works by looking at the physical characteristics of the lens, so on or off should work regardless, you could have something with some kind of internal shutter to cover the lens maybe
But then you would need an IR camera instead of using the phone's camera. An IR camera should be able to find some hidden cameras passively by detecting a heat source.
Perhaps to avoid tipping off the entity recording you by blasting their hidden cameras with bright lights. Granted, the PoC device in the article is not exactly subtly looking, but if you could turn it into a sleek device it would be more useful. Not playing your hand while you're under surveillance lets you control the information they're receiving.
Though the bigger issue with my theory is that while most cell phone and webcam devices have IR filters, many surveillance cameras intentionally do not.
For now, but there's really no point in detecting them anyway, since there are plenty of truly concealed options for those that really want to be pervs.
Yeah I don’t think this will be effective, cameras can be put in certain angles that it can see with being seen, or how police do it, entirely behind clothes or similar fabric where it can see through and identify but not seen even if you’re looking straight at it.

If this worked with IR, and so non visible, it might be even more useful.
Great idea though.

Can’t phone cameras pick up IR?

Pining for the days when phones had IR blasters (e.g. galaxy s6); that would work perfectly for this
some more modern phones from xiaomi still have IR blasters
Why would that be more useful?

I wonder if it works with smart glasses.
You don't need this to detect smart glasses, they're very obvious.

Proctologists agree on this one thing that smart glasses can never conceal.
Cool, but we need that for microphones.
Anything can be a microphone:
