"Invisible" IR camera behind a window?

[ch0wd0wn 0]

Hello

 

I want to buy a security camera that has "invisible" IR...no visible red lights. I also want to put this camera behind a window pointing outside. Will this work?

 

I ask because the regular IR cameras with night vision, when I put behind a window and point it, those little red lights reflect off the window and makes a huge glare...you can't see anything.

 

I'm hoping since the camera's with the invisible IR doesn't have those red lights...it should work behind a window.

 

Please help me confirm before I purchase.

 

THanks!

The 940nm light will reflect back too, you just won't see the red glow.

Ok then will that affect the night vision? Basically will this still work behind a window at night pointing outdoors?

Yes, it will reflect back and blind the camera. One option would be turn off ir lighting on camera and mounting a separate ir light outside. Or possibly a seperate ir light inside shining out through the window would work.
