Idk what I'm doing here. But I love how clearly you explain what you do.
Thank you so much for the video but I cant find the one you are using.. I find mostly square ones for around 5 bucks.. Do you have an exact link?
One question. I saw a similar 12v 30 ir led illuminator. Could I simply connect it to a 12v dc power supply or would I have to add some resistors? If so, do you know which ones?
If you upped the intensity of the light you might see a dull red glow. IR is invisible in most cases but in things such as pulsed lasers or looking a the dot from one you can actually see it through only up to around a certain wavelength. I've seen it before it just looks red but knowing what it is is pretty cool. I could link you to a few papers on the subject if you want though one you need to request.
If could send me those papers i would be happy, i was about to be making a night vision goggles but its shitty if someone without them can see u, cause of the glow…
Hi @furulevi , Thanks for the video. One question from a Noob. Would it be possible to use that as an IR Remote Blaster? Is there a way to send IR signals instead of just On or Off?
Hi, is there any CCTV camera housing that can be used for this pcb?
how do you order the connector , to plug in the IR LEDS
Interesting video, thx. Will a surveillance camera with night vision pick up infrared emitted by an external source, such as a the lamp you built? My camera is inside, and when night vision is on, the ir leds reflect on the window, rendering it useless.
Yes it will pick up because these are IR sensitive, and yes behind a window it is unfortunately pretty useless because of the reflection.
Are the LEDs getting hot when turned on?
Hey man I hada question. what would it look like if u laid your device on the table projected the light vertically and took a photo of your wall?
I guess the light would go a little bit sideways also, but it isn't visible by the naked eye.
Where can I get the same
BUT in a rope setup instead
to spread the the led lights in a line formation say like in a three to five foot spread?
Just order some IR light and place em as you want....
good, some way to always let the infrared access without having to cover the light sensor ?
Maybe short-circuiting the pins of the photo resistor might do that (I'm not sure!)
Hey hi guy's can i use 2 9v battery to connect this please help me with this product which 12 v battery should i use guys
Hello, I have a question about infrared led products
Can I connect the infrared led to the raspberry pi camera
Thank you in advance
i think you can but you will have to remove infra red (ir) filter from there, it will be a violet colour glass or just plate
can you see a little red with the naked eye? my security camers that i have outside, i can see them in the dark shining a little red
850 nanometer is visible, but 940 nm should be 99.9% invisible to the naked eye (but not for cameras).
So you're saying that all red infrared light assist camera are visible to any other camera right ??? Can you make a infrared omnilight that can be used in conjunction with night cameras ??? Please let me know. Thanks
Certain cameras are less sensitive to IR light, they are not all the same. I personally removed the IR lens from my SJ4000 camera, and if I use an IR flashlight that creates a good night vision setup that is invisible to others.
@@furulevi Thanks
How long will a 12v battery power the light?
Depends on the battery. Drain rate is close to 200mA so a 40Ah capacity group 24 battery would run it for 200 hours or so.
which type of LED light did you use?

Is it hot?
* THANKS * *******
Can a smartphone with an app be able to see the light ???
It depends on the lens of the phone camera. If it has IR blocking lens than 90% it won't be visible.
@@furulevi Thank you for letting me know Sir. How about making a FLIR camera would that make the camera invisible ???
. Thanks for the video. Bro you have to put a link to where we can purchase the light
Bro, just look for this on Alibaba:
IR Cut 48 LED IR Infrared Illuminator Board for CCTV Security Cameras DC 12V FY-16048
True he must

@@furulevi are these things safe?
@@unlimitediq1894 obviously?
Im confused, you say its invisible... but some of the light from the visible spectrum must be let out since its glowing purple when you turn it on
Cameras are able to see a bit of the ir light but for your eyes it is invisible
@@barackobama2295 Ok I thought the guy in the video could see it glowing purple. My bad
You can point your smartphone camera to your tv remote
Try pressing a button can you see it with your bear eyes, then try seeing through the smartphone camera
@@antreaskonstantinou8585 yes I know that "trick" - doesnt work with iphones as far as I know since they have an IR filter.
If im in the dark I can see some weak brownish color coming out of it. Did it with several remotes, so suppose they leak a bit of the visible light as well 😊
He doesn't see purple, the camera does because he took off the IR filters to see it
You took that out of a security camera

0:25 That connector is likely a JST-XH 2.54mm male. Pls verify if it is, and include it in the description. It will save us time.
2mm (measured)
@@furulevi JST-PH is 2mm pin to pin.

Will it run on a nine volt battery
Even if it would work at that voltage, at 200mA typical current draw for a light of this size it would last for less than 2hrs. Probably closer to 1 hour at that drain rate.
se ven pocos vídeos mostrando la cámara en la oscuridad como emiten ese haz de luz roja (ir led) lo cual hace la cámara totalmente detectable y siendo fácil de inutilizar no entiendo porque no aplican leds IR de 940nm
Para mi las cámaras en cuestión fallan en que no dispone de IRled de 940nm por lo que e la oscuridad la cámara será bastante llamativa y accesible (emite una serie de luces rojas) pudiéndola destrozar o robar o inutilizarla. Las cámaras deberían llevar un sistema de IRleds que en la oscuridad no se iluminasen en el mercado ya hay modelos que utilizan leds de 940nm los cuales no emiten ningún tipo de luz en la oscuridad y por tanto hace que las cámaras pasen mejor desapercibidas, es importante que dispongan de WDR, IRCUT, P2P, codec H.265 o H.265+, conexión POE, wifi , aspectos como sensor PIR, PTZ, son cuestiones a valorar y que mejoran bastante la seguridad
y las prestaciones de la cámara. Dahua por ejemplo ya tiene unos modelos (DAHUA UIR) y HIKVISION creo que también en algunos modelos está implementando los leds de 940nm
Is it 3mm or 5mm IR lED ??
5mm
I bought this exactly IR light from Amazon.
In a complete dark room it doesn't iluminate anything AT ALL.
@fluffyhamster9471 my phone was able to see the light from a remote control, so I thought it meant it could see in a dark room illuminated with that IR light. Not the case, though
Hey bro I have too these exact thing how i connect them to Esp32 help I have project urgent thx
can you put a link ?
Isn't 940 dangerous to human eyes?
Looking into a light for too long without realizing it's on can be dangerous. However, small LEDs aren't very powerful and you aren't normally staring directly into them at short distances. A powerful infrared floodlight could hurt your eyes but only the military uses them.
Good
No led glow are no red glow
People need to tell Google to f*** off and stop telling people to switch to Chrome. I don't like Chrome, it's a shitty browser. I like Internet Explorer where I can virtually change all the browser background to any color I like. With Chrome you get this bright white light that will destroy your eyes after a day stuck on a monitor. Try each day and see how you start to go and see an Optometrist. With Internet Explorer you can actually change the background of anything, including Microsoft Word, Outlook, Excel, etc., to the color of your choice, the color and size of Fonts, etc. I wish Google stopped telling people what to do with their lives. They are actually forcing to kill Microsoft, their IE browser, etc. and grab the sheep for themselves. I find Google quite offensive in my opinion. And the ads, oh these fkn ads, they're everywhere. Go back to IE and see you will watch a video without being bombarded by ads on gambling, cars, cars and more cars, dating agencies and scammers. One has to be really blind not to see what Google is doing to us all just to grab every penny out of your pocket. And I am sick of this pushy-pushy attitude with Google.
You can change colour on google chrome
