So-called spy-cam porn has existed in China for at least a decade, despite the fact that producing and distributing porn is illegal in the country.

But in the past couple of years the issue has become a regular talking point on social media, with people - particularly women - swapping tips on how to spot cameras as small as a pencil eraser. Some have even resorted to pitching tents inside hotel rooms to avoid being filmed.

Isn't there a method using your camera flash to detect cameras?

[–] ageedizzle@piefed.ca 1 points 10 hours ago (1 children)

One option discussed in the article is pitching a tent in the room to avoid being seen. Sounds extreme but honestly might be worth it as these cameras get harder and harder to spot

Pitching a tent when I was in high school didn’t help me not be seen.

Where? I’ll make an account and share for a bit of cash…

Rather than a flash, you could turn it on as a flashlight to look for reflections from hidden can lenses.

You can also point your phone camera around to look for the IR led on a hidden camera. Note that the rooms lights should be turned off and any curtains closed for this to make sure the hidden camera goes to "nighttime" mode. You can check if your phone will work for this using a good old fashioned remote control with an IR led and see how well its picked up by your phone.

You can also use your phone to check for WiFi networks that seem suspicious.

Don't forget Bluetooth. I have a handy app called "Bluetooth scanner" which scans for Bluetooth signals.

It creates a list with the names of the devices it finds, plus other info like the device's internal name, vendor name, BT address, signal strength, protocol and so on.

It even has a feature which helps you find the device based on changes in signal strength as you walk around.

The theory is to detect infrared light for the cam who utilise infrared night vision, but from the article it seems that they don't use that at all, so when the light's out no one can view anything. This might be the reason why it went undetected.

That's one method, also camera sensors have a retro-reflective effect that makes using a camera flash highlight other cameras in its field.

[–] alaphic@lemmy.world 13 points 1 day ago

I suppose you could theoretically utilize the flash functionality in an attempt to catch some sort of glare/reflection back from the hidden camera's lens... maybe? This is just a guess, however, tbh, and I have my doubts of its efficacy against the borderline frighteningly tiny lenses in use on more modern equipment that is designed specifically to be hidden. The pricier gear could (potentially) even utilize special coatings or treatments intended to mitigate such a detection method for that matter, as there's clearly no shortage of money surrounding the... "industry," for lack of a better term.

I certainly wouldn't consider it a reliable test, that's for sure

Joke's on you. I'm into flash porn.

[–] runsmooth@kopitalk.net 1 points 1 day ago (1 children)

Share bud, there's ladies living in tents in hotel rooms. I'm considering it.

[–] otter@lemmy.dbzer0.com 1 points 18 hours ago

Hell, living in hotel rooms sounds intense enough as it is.
