So is it a myth that we can’t see above 800nm lights ?

All depends on your digital sensor, what wavelength you need.

The advantage of a 940nm IR, is that it is less visible to the naked eye. This makes it much better, especially if you need to be covert. Night Hunting etc.

@sergiosecreto3189 Жыл бұрын

hello what is the camera modell you tested them? I think it also depends a lot on the camera. or am I wrong? I have already seen cameras that could see perfectly the 940 too but of course for the human eyes it was invisible.

Thank you. Your video is very informative. I'm definitely buying a 940nm based on your video.

IR is used for stealth. It makes ZERO sense to use 850nm as it glows really well to be spotted easily.

Beware if the IR light frequency (850 or 940nm) doesn't match your camera sensor frequency you will have much less intensity (half??) resulting in significant loss of range.

@sergiosecreto3189 Жыл бұрын

so yes exactly, that's what I have written too. the big question is the sensor of the camera. but I also think it is very diffocult so decide cause only later and via testing you can see the result

The military uses the 920 to 940 nm illuminators since it provides better lighting and it won't give your position away to those using conventional optics searching for that telltale pink glow from the 840 equipment.

Good evening. Sorry for the inconvenience. I ask you a question. I need a powerful infrared led system so that when placing it next to a written plate, and I need that when someone takes a photo (during the day) of that plate, the photo appears "burned" or at least it is not understood what it has written. Is there any led with which I can achieve that? What do you recommend? The important thing is the clarification that is that it has to work also during the day (not only at night). Thank you very much and sorry for the inconvenience.

@hamitinan6422 2 жыл бұрын

Light the plate with and shoot a film on the plate. The IR lights from the cameras will be stuck in the filter and will be invisible ;)

The 940nm has a more evenly distributed light and yes, it is also brighter than the 850nm. I think you should check your video and see which is brighter. I would rather have the 940nm IR in my cameras than the 850nm to keep them away and hidden from preying night owls (vandals, intruders). The 940nm doesn't attract flying insects than the 850nm which pull insects towards the camera like magnets, resulting in constant fake alarm and sleepless nights.

Hello, @cahoc99. A night vision camera has no infrared filter inside the camera lens, whereas normal cameras like on an iPhone has a filter so the image looks the same as the naked eye.

It's pretty cool how with the naked eye when you turn on an infrared lighting device you don't see anything at all however when you look at it through the camera it shows you how bright the light source actually is.

@wtfvids3472 6 жыл бұрын

That is strange, humans are not supposed to see 850nm in fact anything over 760... Do you know why this light can be seen?

@usbtower4358 6 жыл бұрын

If it only produced 850 we would in fact not be able to see it, but no LED is perfect, and alongside 850 it emits some light in the visible range. The 940 LEDs produce light mostly in the 940 nm range and a lot less visible light, if you load them to capacity, or overload them they too will produce some visible light, a lot less than the 850s though.

May I know the camera you use.. And if I use 50 940nm ir led,how much voltage and amp I need?thanks

@tocadisco4166 6 жыл бұрын

Ir LEds typically have a forward voltage of 1.5V, so if you want to use 50 of them connected in series, ou simply need to multiply 1.5V x 50 leds = 75 volts. The current will depend on the type of led. Small 5mm leds will require about 25mA. Instead of using theses 5mm leds, I recommend you to test some larger 3W power leds. Each one will require 700mA and 1.5 volt to work.

@CoolShot906 6 жыл бұрын

Toca Disco well,thanks!

@usbtower4358 6 жыл бұрын

I would add that the LEDs require constant current rather than constant voltage power and if you are experimenting with a regular constant voltage power supply, I would connect a small resistor in series.

@miguelangelsimonfernandez5498 4 жыл бұрын

@@usbtower4358 Actually they don't . They are more efficient in pulse mode and a higher voltage than nominal DC voltage. You would need a pulsing (forward ) current at a frequency higher than your camera shutter frequency. Using direct DC depletes your batteries fast.
