I worry that when the product becomes "obsolete," they just stop updating it. I did request that they add DVD menu support--that would be enough for me to love the product.
I just got two DCS-900 Dlink cameras and was so impressed that I ordered two more. The included software supports 4 at a time so I thought I'd stop there..and in the past I've always had 4 USB cams hooked up. These ethernet cams are much better. I am even impressed with the low light performance a bit. While it is grainy, you can actually see quite a bit of detail. When it's pitch black, you do see grain, but I'm still impressed. I will get them setup to post a pic to my local ftp server and then I'll write a little Perl script to navigate the images...I like to save an image every minute and then include the Day name...so Monday_13_34 would be a pic Monday at 1:34 PM. That way, I can easily navigate the past week of pictures...I'm not sure how great it can get there..haven't played with the FTP posting timelines but I do see some variables that can be used. lol. Way to get off topic but it's another network appliance to think about. If part of the screen is light and another is dark, the dark part gets very grainy. They are $80 on Amazon which seems to be the cheapest of anywhere. In good light, they look amazing. I like setting my web script to auto advance every second and auto advance a minute or two at a time...then I can watch the sun set.
I think the desktop software is somewhat unnecessary in many situations. It has more motion capture settings and other things but the web interface is probably enough and at that point, I don't have to be limited to four cameras. I like to have one aiming out each window. Considering how nice these are, we may try to install one in our front driveway and then we'll want a monitor showing all of them all the time or cycling. Ahhh..security. How fun?
