Hi,
Here's some pictures of what the video mirrors look like at dusk and near dark -- it's a little tricky getting an exposure that shows it close to what I can actually see!
These are getting progressively darker top to bottom -- the middle one makes it look darker outside than it actually is, and the cameras really seem to open up their apertures in this light, and they sometimes are slightly overexposed on one or the other, depending on the direction of the sun. The last one is sitting in my driveway, and there is very little ambient light -- you can kinda make out the light thrown by my taillights in the right screen...the light ahead is my porch light.
