Hi JavaLawyer, a couple other items:

• I have a DCS-2230 pointed out a window.  When the conditions are sunny, any shadows appear way too dark, much darker than in real life; this decreases contrast of any objects in the shadowed area.  Hikvision has "Wide Dynamic Range" mode which seems to compensate for this and provide more true-to-life range in the image.  This type of feature would be very useful.
• Per a post I made a few weeks ago, the DCS-2230--at least when using MJPEG--does not provide anywhere near its stated frame rates when multiple profiles are in use.  In one case I measured 3-4 fps at 1080p when the profile was set to 1080p@15fps MJPEG.  Would be nice to see this improved!

I haven't had any shadow issues. Are you in outdoor or auto mode with 24 set? Maybe you have more shade than I do.

I always suspected #2. I left 2 of my 2230 cams with 2 profiles.

On the frame rate issue, I have three profiles set:

• 1920x1080 MPEG4 at 15fps setting (because you have to have profile 1 set to 1080p)
• JPEG 1280x720 at 30fps setting (for recording to ZoneMinder)
• JPEG 320x176 at 15fps setting (for motion analysis in ZoneMinder)

Actual framerates achieved for #2 and #3 are 11.1 and 5.6, respectively, so I'm getting about 1/3 of the set frame rate.

Here is a snapshot of what I see with Outdoor/24dB exposure.  The shadow is not dark in real life at all, but the camera darkens it significantly to the point where motion detection is no longer practical.

Might need 2 to 3 cams in that situation.  That's a tough scene.

Does the image get brighter if you turn the cam to shadow only?

Yep!  Unfortunately, putting a cam on the neighbor's house is probably not an option here 

Does the image get brighter if you turn the cam to shadow only?

Yes.  Or, if the sun goes behind a cloud, the shadows get much, much brighter.

The 2230 does quite well in relatively consistent lighting, but it has difficulty with high contrast situations.  Other D-Link cameras I own (942L) have the same issue with indoor scenes.  I have a camera pointed at the front door, and there is a light fixture above the door.  If someone enters and flips on the light, the high brightness of the lamp causes the person's image to extremely dark.

• JPEG 1280x720 at 30fps setting (for recording to ZoneMinder)
• JPEG 320x176 at 15fps setting (for motion analysis in ZoneMinder)

I made an interesting discovery.  Changing to two profiles instead of three, with Profile1=1920x1080@15 MJPEG and Profile2=320x176@7fps, helped a little, with the actual 1080p MJPEG frame rate rising to just over 7fps.

I then changed Profile 1 H.264, instead of MJPEG, but still couldn't get more than 7fps from Profile 1.

I then changed Profile 2 from 320x176@7fps to 640x360@7fps and BAM the frame rate from Profile 1 shot up to 17fps (above the advertised 15fps max) and stayed there!

So now, my profiles are:

• 1920x1080@15fps H.264 (CBR 1M) actual frame rate: 17fps
• 640x360@7fps MJPEG actual frame rate: 7fps

So, it seems that certain image sizes overload the camera.  800x450 seemed to work as well, but 480x270 caused the Profile 1 frame rate to drop.
