It is a method where your machine registers with a central machine, and a DNS entry is updated for your machine. That allows people external to you, to reach you with a symbolic address. If you're using a router with your cable or ADSL modem, the router may have a setup page in it, which registers the public IP address being used. My router has that feature in it, and since I'm using a router, I would use the router DDNS feature, rather than setting up software on my PC. The service is actually provided in that particular case, by the company that makes the router - they're running a dynamic DNS service. http://en.wikipedia.org/wiki/Dyndns http://en.wikipedia.org/wiki/Dynamic_DNS List of some free and commercial dynamic DNS providers. http://www.dmoz.org/Computers/Internet/Protocols/DNS/DNS_Providers/Dynamic_DNS/ The deal with this is, you shouldn't change the IP address of the computer too frequently. One of the services will only support one change every fifteen minutes. (If you make a nuisance of yourself by changing addresses more frequently, they cut you off.) My setup might average two different IP addresses per day, so I wouldn't have a problem staying within the limits. When your IP address changes, there is some delay before the DNS tables are updated. So if you were attempting to run a commercial enterprise, on top of a residential Internet service with a dynamic IP, your customers would be none too happy. The service is not entirely seamless, but it is better than nothing. It is in your best interest, not to be changing the IP address that often. ******* In terms of your other questions on surveillance cameras, it helps to frame the question in terms of your requirements, or what you hope to do. Surveillance cameras are a bit of a rip off (ask me how I know this :-( ). They can easily be inappropriate for the situation. You might record some activity, but later when you or police look at the recorded footage, it might not be good enough to identify anyone. If you take a 640x480 pixel camera and film a football field, the faces are "three pixels high". Don't expect miracles from the thing. You could easily be throwing away your �250.00 . It all depends on what you're trying to do with it. http://www.ehow.com/facts_5958600_ptz-motion-tracking-camera_.html Paul

If its for your IP CAM then there are probably better ways of setting it up. regarding your IP Cam's I have some very limited experience with them, as I set up a few for someone to monitor his disabled wife while he ran errands, I think they were panasonic cams with pan & tilt, they come with software that allows you to recorded and access them remotely, if you have broadband with a dynamic ip then you can usually set your router to never release the ip address, this isn't perfect tho.
