Hello all. Long Time Lurker. First time poster. I am looking for opinions from more experienced people than myself on this. I am looking for a decent 4 Channel DVR based system. My requirements that I am looking for is, DDNS Motion - Email Notification Web Browser capability - only if they have a static IP. <- Not mandatory if it doesn't have it. The one I currently am using is having issues with DDNS not keeping up. Let me hear your thoughts. I appreciate all your help in advance.

What routers are available out there that support DDNS. Actually what are proven ones?

It is about 30.00 a month more in Southern Cal and Arizona. They require you to be on a business plan. Also it is not so Much the DDNS as the DVR with Email Notification motion detection.
