Thank you, Dave. Yeah, I understand that this warning is somewhat
perfunctory, but it was so prominently displayed in the manual and a
friend was just complaining about RFI from LED lights. Those two things
got me to wondering if these things (IR LED arrays) are a know problem
child, or just one of the many things that can be a problem, but not
always are a problem. This one takes +12V input, so I suppose the risk
is low that the array itself is going to be an interference source. I
assume the RFI problem with LED lights is actually the switchers that
supply them rather the the semiconductors themselves and I can always
use a cleaner external supply if the one that comes with this unit is junk.

Here is the required statement:

limits are designed to provide reasonable protection against harmful

uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful

that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one
or more of the following measures:
* Reorient or relocate the receiving antenna.
* Increase the separation between the equipment and receiver.
* Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
* Consult the dealer or an experienced radio/TV technician for help.

I have a couple of south facing security cameras that I have tucked
under the soffits of my high desert cabin so they don't get baked
by the
high desert sun. The tradeoff for this is that I am getting glare off
the soffit from the camera's built-in IR LED arrays which spoils the
night vision image quality. I am thinking of purchasing some
external IR
LED arrays to solve this problem.
I found a positive review of this illuminator, but I got a little
worried when I saw the FCC part 15 warning prominently displayed
in the
user manual:

I am not aware of any interference from the IR LED arrays that are
built
into the cameras, but just in case these illuminators are more
problematic I thought I would run this by the reflector before I
press
the "add to cart" button.
Thanks,
