- kcmastrpc 8y agoOr just turn off all the lights in the room and use your iPhone camera in live mode - hidden cameras (and their IR emitters) will light up like a Christmas light.
- ungamedplayer 8y agoIs this an iphone specific thing ? Have you tested it.
- henryackerman 8y agoDepends on whether your camera is equipped with an infrared filter. Some older camcorders actually have low-light modes based on infrared or near infrared light. You should be able to use those as well.
- zeta0134 8y agoIt's not actually. Most digital cameras pick up infrared light, especially cheaper ones. Maybe not professional cameras, which might have an IR filter for better color accuracy. The filters are not cheap and IR doesn't affect the image quality all that much. Try it out; point your TV remote at your smartphone camera and push the buttons. You might be able to barely see the light with your eye in dark conditions, but the blinking pattern should be bright and easy to see through your phone.
- Cthulhu_ 8y agoI've tried this; you can definitely pick up the IR light with the front camera of your phone. Rear camera has an IR filter in modern cameras or something.
- PopeDotNinja 8y agoCan confirm. Just saw red light on my TV remote w/ my LG G5. Pretty interesting!
- jpindar 8y agoEvery camera I've tried this with displays the IR as a pinkish purple color. You can sometimes see that same color in photos of things like sunlight reflecting off of chrome, or refracting through windows.
- derrasterpunkt 8y agoI only have an iPhone 5, it works with the front camera. The back camera has an IR Filter.
- huhtenberg 8y agoNo, it's not iPhone specific. You can always test yours with any IR remote control - just point it at the camera, press any button and you should see the LED blinking.
- ataturk 8y agoIt's pretty sad that these days we are using tech that would make a 1960s spy feel ill-equipped just so some a-hole can't film your wife in a shower at a rental house.
- martin-adams 8y agoYou can test it with a classic remote control where you can see the beam when you press a button if you point it directly at the camera lens.
- llampx 8y agoThat's only if the hidden camera is actually using an infrared led / led array. Also you might have better luck using the front camera because it is more sensitive to IR.
- icebraining 8y agoIf it isn't using infrared leds, you can at least get undressed in the dark with little worry.
- abstractbarista 8y agoThis may vary based on the wavelength emissions from the IR LED's: https://ellipsesecurity.com/2018/05/850nm-vs-940nm-ir-illuminator/ https://ellipsesecurity.com/2018/05/850nm-vs-940nm-ir-illumi...
- artiscode 8y agoAnother option is to get a camera lens detector device. It works by detecting the curvature of camera lens.
- icebraining 8y agoHow does it detect the curvature?
- nzjrs 8y agoI think it probably measures the curvature and if the curvature exceeds the normal parameters of non-lens objects then the device has curvature and can be detected.
- throwaway2048 8y agoYou can also use a non linear junction detector https://en.wikipedia.org/wiki/Nonlinear_junction_detector https://en.wikipedia.org/wiki/Nonlinear_junction_detector They are electronically very simple (they are the boxes with wands and earphones you always see in espionage movies)
- h0l0cube 8y agoQuoting from the wiki article: > As a countermeasure against an NLJD, professional covert listening devices (bugs) of the Central Intelligence Agency were equipped from 1968 onwards with a so-called isolator. An isolator is a 3-port circulator of which the return ports is terminated with a resistor. Any energy injected into the bug by an NLJD, will be absorbed by the resistor, resulting in no (or very little) reflected energy. An example of such a bug is the CIA's SRT-107. Do modern concealed spy cameras have this kind of tech? Is there anyway to counter such a counter-measure?
- throwaway2048 8y agoIt would require it being built into the IC itself, and no ICs except ones intelligence agencies have access to are going to offer this feature, because it has no other real purpose than evading NLJDs
- owenversteeg 8y agoBut they are about $10k, and sadly one of the few things where I don't think there are any working DIY ones.
- appleflaxen 8y agothis doesn't help when it's hidden in the workings of another electronic device which creates heat.
- usefulcat 8y agoI think the general assumption here is that a hidden camera would be likely to use active IR illumination.
- appleflaxen 8y agoah; I misunderstood. thanks.
- Cthulhu_ 8y agoI saw a random video clip yesterday where they clipped a red transparent card over the phone camera; turning on the camera flash, and scanning the room using the camera's video camera mode. The light from the phone reflected in small spy cam lenses, showing up as tiny red dots on the screen.
- hokumguru 8y agoCan you link a source to this? It sounds incredibly cool.
- copperx 8y ago> You can get a used FLIR for around $100. The cheapest ones I have found are around $500. What FLIR device are you talking about?
- RandallBrown 8y agoYou can get the one for smartphones for $200 brand new. https://www.flir.com/products/flir-one-gen-3/ https://www.flir.com/products/flir-one-gen-3/
- dwighttk 8y agosidebar: Why did "forward looking" get glued onto that acronym? Why not just IR camera or detector? Did the military have less popular rear or side looking infrared devices? maybe "FLIR" was just fun to say? On a rocket powered missile rear-looking infrared seems pretty useless.
- alexhutcheson 8y agoYes, early infrared imaging systems were "push broom"[1] scanners facing perpendicular to the direction of travel. Forward-looking sensors required some additional tech to be developed: https://en.wikipedia.org/wiki/Forward-looking_infrared#Origin_of_the_term https://en.wikipedia.org/wiki/Forward-looking_infrared#Origi... FLIR is arguably a misnomer when applied to handheld devices, though. [1] https://en.wikipedia.org/wiki/Push_broom_scanner https://en.wikipedia.org/wiki/Push_broom_scanner
- taxidump 8y agoAlso remember, thermal heat would be present and difficult to isolate from hidden cameras located in seemingly harmless electronics.
