Why Use Visible IR LED's?
-
I'm curious why the Argus uses IR LED's that emit some visible light? Especially when there are IR LED's that don't emit any visible light and aren't expensive. I don't like the idea of a home invader being able to see my camera's red glow, then single in on it and disable the camera or steal it.

I just got a Reolink camera and noticed the same thing, I never saw IR LEDS that emitted visible light before.
Like you, I would prefer they did not glow, but maybe it was done as a deterrent to let people know the camera is there. -
The problem with it being a deterrent is that once the camera is spotted it can be damaged or stolen. I'd rather its location not be seen.

I am with you. In doing further research I discovered that these visible light LED's emit more infrared light so they light up the things in the dark better. That would give better range to see things so I guess it is a trade off.

We won't know if that's the reason why Reolink picked visible light LED's, because they won't tell us. But I'm thinking that non visible LED's cost a little more and that's the real reason.

Black IR 940nm is not so efficient.
Red IR LEDs is for variable using the better choice.
I hate the red lights also, but I have test a black IR Beam and the results are not good.
The "klick" at start is in my eyes more a problem
And a little percent of people can see the 940nm lights.
