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.
If you're being surveilled in a way that you don't want to tip the observers is one thing, but if you're in an AirBnB type place, fuck 'em. I'd even be fine with running some lasers in the place that ruins the sensor.
I'm an adult male so I don't care if someone wants to record my dong but this is very helpful for families with kids.
Unless the hidden camera has IR capabilities.
That's actually much easier to detect, any camera without an IR filter would show an LED emitting where your eyes did not, no complicated solution necessary.
