Depending on your budget nuuo.com sells software to monitor cameras at the same site, or several sites. They give you a 30 Day full demo version to try, and I must say it's some pretty good code! You'll really like their "digital PTZ, and Zoom fetures! As for me I'm looking for a "Really Good Expaination" of D-Link's DIR-825's "WISH" tool (Wireless Intelligent Stream Handling). I haven't found anyone that knows ANYTHING yet... Try nuuo, and I beleive you'll be a believer too!
