I have an IP cam based on the ICamView software. Just successfully compiled this proxy to get streaming working
http://www.barkered.com/2008/04/07/icam ... -icamview/
sudo yum install SDL SDL_net SDL-devel* SDL_net-devel*
unzip ICamViewProxy.zip
cd ICamViewProxy/
chmod 755 ./linux_build.sh
./linux_build.sh
./ICamViewProxy -camhost 192.168.1.110 -camport 9001 -camuser viewer -campass viewer -proxyport 8888
where 192.168.1.110 is the IP of my camera and created a user viewer with password viewer (view only). Remember to configure ZM settings to your PC IP address or localhost on port 8888
