Does the black Fresnel affect the PIR sensor?  Reason I ask is that it seems like the Fresnel is the first thing I spot when looking for a camera.  If it was black I think it would help on camo for 'prying eyes'.

i does not affect the range it picks up but with the black fresnel it is a bugger to see the red blinking light for the walk test

Doesn't affect the PIR sensor but if you have a build with an internal slave flash and the CDS is behind the black Fresnel, the board will always see it as being night and the slave will fire even during the daytime.

Just trying to clarify it some more. Know for the internal slave to flash it has to be triggered by the camera flash so if the control board is also hidden by the black fresnel that the camera (whether with an internal slave or no slave) also will flash everytime?
And again liked you and Ken and others have told me when I keep forgetting and asking you you could route the cds so it is facing through say a small piece of clear glass, etc. that is set somewhere other then behind the black fresnel...but is another place for possible problem from a leak.
What about using a black marker and rubbing some on a white fresnel and immediately wiping it so it is shaded darker but not black. Just sense later and earlier in the day/evening?

You can always move the cds off the control board and put it in the case so it will see the sun.

I guess I should amend my statement above as it isn't entirely true. The slave flash will fire during the day if the camera is set to forced flash and the CDS is behind a black fresnel. Even if the camera isn't set to forced flash, if the CDS is behind the black Fresnel the slave would still go through the refresh cycle during the daytime and waste battery life that it wouldn't normally use. Yes, you can mount the CDS in another location and that would prevent the slave flash from refreshing during the daytime and I have some builds that I have routed the CDS out the bottom of the case and enclosed it in a small glass bottle and I have seen other builds where the CDS was positioned behind the camera flash glass so it can detect the light level. You also have to realize that I am only talking about the CDS that is on a slave controller board and not the CDS that is on a camera controller board unless the camera controller is designed to control both the camera and the slave flash such as the AIO and the Safari with Flash Backpacker.

Boy you don't read my replies do you Charles. [rofl]

So none of my builds have slaves yet, and the ones I have so far I have no slaves planned for.  It won't hurt on those to just color in the Fresnel's right?  It will only become a problem on an internal slave in which the CDS is on the control board.

Correct, as long as you did not use the SnapshotSniper LCD board in the build you will be fine.
With the LCD board you must use the white Fresnel although you could still color it in without affecting the detection ability or distance.

Here's what I did on my first internal slave build. I was using a Bigfoot slave board and not knowing better just ran the cds to where it says glass (was old glass from a s40 lens) and the pt to the camera flash hole. Just used black sharpie and would put a few squigglies on it and immediately rub it with my finger to get it to darken some. You can see the difference. Is just enough that doesn't stand out.
btw I usually find mine by seeing the Python lock around the tree. [biggrin]

I agree the strap or python gives it away first.  I use Joe's mount when I ca, but that gets expensive after awhile.  The ones I have to use a strap with I am going to get up in the air.  The best hidden one I have is following Don's mini build in the 1010 case with Joe's mount.  Once I color the Fresnel (which was what this question is about) it will be virtually impossible to pick out unless you know to look for it.
(Now having said this, it will be stolen in a week.)

I like to color the fresnel with a little coat of face paint. It helps the freznel blend in with the rest of the cam and doesn't restrict the sensitivity or day/night capability and still lets you see the red leds for the walk test. It will rub off though so you have to reapply every now and then.
