infrared trailcams
I know these are advertized as having no flash but I want to know from people that have them, are they really undetectable when they go off. I'm wanting to do a little surveillance on one of my properties that's getting vandalized. And how is the picture quality?

RE: infrared trailcams
I haven't read anything about these yet since I don't own a trail cam and hunt public ground, but if they truly have an IR-only flash, then deer won't see them. Humans can't either, even though we see regular red just fine.
Deerjust don't have the right photoreceptors in their eyes to be able to pick up anything at the red end of the spectrum. Even blaze orange looks like a washed out very pale yellow to them. They can see very well in the blue region though, and possibly UV.
The flash is probably IR only. If the light source consists of LEDs, then you can be assured it's only putting out a single wavelength. The nature of the LED makes it monochromatic (one color only).
There are several sources of IR only lights and strobes that are being used for IFF (Identify Friend or Foe) applications with military units to prevent BOB (Blue on Blue incidents or 'friendly fire'). There are lots of IR spotlights, flashlights, and filters on conventional lights that help make use on NV gear so they can light up the night, and leave the enemy unaware.
It was only a matter of time before it got into the civilian market. The civilian technology will just always be a generation or two behind the newest/best stuff.
