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  ;D

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.
