Since working more with this camera in an attempt to resolve the 'foggy' viewing conditions at night, I've identified the source (or indirect source) of my problem.
As mentioned above in the previous comment, I mounted this dome camera within a fake 'bird-house' looking out the round port hole. By using another video camera, I was able to "see" the infrared emitting from this dome camera as mounting in its installed location.
What I discovered was that while the camera had a wide clear view looking through the port hole, the IR energy from the IR LED's was strong enough to reflect off of the plywood 'port hole' edges (painted amber yellow), and reflect back up into the glass lens area of the dome camera.
The simple fix was to just paint the plywood edge "flat black" to eliminate the IR reflection. Presto - a beautiful night time image with no haze or foggy appearance. The area of our mailbox at the street is pitch black, but the IR from this dome lights up the entire area and out to +100'.
What seemed like an issue with this camera, has turned out to be a plus since the power of the IR LED's are that powerful and nearly invisible to the naked eye. Therefore, I'm raising my rating to 4+ stars for this dome camera.
I would have liked to show a before/after snapshot, but don't see a way to insert the jpg's here. Also, this dome camera is bigger (compared to other like domes) than one might expect from the photos.
The all metal construction, sturdy/compactness, IR emitter power, remote Vari-focal lens and 1080p HD make this camera one that I would purchase again. The daylight view is very clear/HD quality and the night time view in total darkness is quite impressive.
