If you are accessing the cameras using the links I provided (using the ddns and port information), then it would be slower than normal because you are actually accessing it over the Internet. If you are accessing the cameras though their IP address on the local network, then you shouldn't be having significant issues concerning lag. Also, you might try using a different Internet browser (Mozilla Firefox, etc) to see if it's a problem with how the Internet browser interprets the code from the camera's website. I've seen a camera work flawlessly in one browser and be a real pain in the other browser. At the end of the day, this issue isn't that important as long as you can get your cameras set up the way you want them...because icamsource, when you start using it, will not be pulling the full webpage from the camera. It just uses a script on the camera to login and then just fetches the video images. If the camera freezes when you have icamsource running, THEN you should definitely get new cameras. I can't speak to the quality of those Linksys cameras. I use D-Link DCS-910's and DCS-920's in my setup. The image quality is ok for use as a security camera in combination with iCam, and they are cheap. The cameras have never froze up on me...which is important to me. I'm not sure that they would survive outdoors though...they definitely weren't made for outdoor use.
