Two cameras with night vision side by side, one has a red glow to the leds while the other does not both function as in can see in the dark. What technologies are in use here?

[G+_Jason Perry]

They both are relying on IR to light the area. I find the cheaper cameras use red LEDs and rely on what spills over to IR. Personally I haven't noticed any difference, I am guessing it is just cost savings.

Jason Perry My reason for bringing it up has to do with stealth security. The red LEDS tend to give away the location of the camera. I can disable the LEDs on the camera

UVC-G3 but would need an alternative night vision lighting source. Any Ideas?

[G+_Jason Perry]

Sounds like a good DIY project. If you look at Fr. Robert Ballecer, SJ?'s grow light from salvaged computer parts I think you would have a good start. You will probably have to substitute the strips for actual LEDs though

Jason Perry Thanks Jason, how do I identify the type LEDs to use which do not glow in the dark?

[G+_Jason Perry]

The data sheet should tell you. The visible spectrum for a typical person is 390 to 700nm so you are looking for something over 700nm

Jason Perry Great, Thanks.

I might already have the correct night vision LEDs. This was my thought after reading this:

Wave length 850nm Infrared light. The beam lights is INVISIBLE to naked eyes but give a red glow.

Did not think it was going to be this difficult to locate the IR spec for the UVC-G3 but so far no luck.

The ones linked are 850-940nm. I hear there are also ones that are 940 with a +/- of 25nm. I think that's the best you can get in surface mount. The+/- constraint should keep out of the human visible spectrum. Be careful with brightness, it could still still at max with some, also consider the eyes of pets/animals.

And they are cheap. If your camera has 850nm LEDs I would try the 940nm LEDs

Jason Perry Contacted the manufacturer but the help could not tell me what part of the spectrum the cameras are setup for so guess if they are cheap I can do my on testing. Thank you David.
