Subj : IR Light Question

Hi Folks!

Have a couple of cameras with Infrared capabilities for night/low light
viewing.  Guess worked OK: I have the cameras inside looking out their
windowd and the built-in IR LEDs reflected in the window pane and
effectively blinded the camera.

Electrical tape over the built-in IR LEDs, so yes, a replacement IR
source installed.  Camera is separated from the IR light by ~6 feet, so 
no reflection.  Also no IR image.  The IR Light is supposed to have a 
distance of 20 m, so ~60 feet.  I don't see any difference; I did go 
outside to test by putting myself well within the camera's detection
area -- nothing.

AFAICT the light is working: I have one of those IR detection strips
(for testing remote controls) - glowed.

So any idea what to do?  Putting everything outside creates another set
of problems.  Half-wondering if the window glass is causing the problem:
has a "UV Block" which does work -- charging via solar panels inside
does not work.  I know UV and IR are on opposite ends of the visible
light spectrum, but maybe this "UV Block" stuff takes out more than just
UV??

Thanks!
