Pros: Solid case
Reasonable picture quality
IR night time lightinig
Replaceable lens

Cons: Windows-only configurator
Non-standard output format
No API documentation

Other Thoughts: I've done some research and placed results at http://kuklin.ru/ip400cam/
Config;
Smth like 192.168.1.135 by default
Windows-only config
You can get two config sessions tcpdump files: http://kuklin.ru/ip400cam/tcpdump/.
First one is for static ip, second - for dhcp. config.png - config program screenshot.

http://$ip/image.jpg - still image

Still mode is rather slow. Streaming is about 20fps.
I wrote some scripts to convert non-standard output to usable one (see tools subdir) - uicam2jpg.pl outputs MotionJPEG to stdout, uicam2jpg1.pl writes frameXXXX.jpg. See samples at 'pictures' dir.

Bottomline: Good device for IT specialists. Could be used for real surveillance systems.
Just a toy for user.
