- 6480e can connect to multiple IP sources so using that will allow you to have one source for viewing, admin, ect. CM3000 is a good thing also, just trying to keep it simple
- viewing via the internet? If it is via Local Area Network (LAN) then yu can leave it stream since it won't impact poorly on overall LAN. If it is via the Wide Area Network (WAN) then it becomes an issue of bandwidth. Why do you want to stream 24/7? The 6480e can send emails with snapshots of motion if you want?
- live monitoring in general is a great idea as long as you can pay to have that service. Otherwise I'd recommned that you tell them "it's recording and you don't need live monitoring" and an occasional lookie evry now and then works great.
line drops??? battery back up will carry the equipment and if this is all lne of site short distance you won't have a line drop issue. chances of the line droping are pretty nill.it will happen, but, the "instance" will be small. If you use the analog with the 1304 you'll have a recording on the pole and on the 6480e so tha linedrop is not an issue.
You can also use the I/O part(s) of the 1304 or 6480e to setup alarm triggers. I've used the following wirless relays to provide 100% trigger events and/or motion detection into the 6480e so that when triggered under specific rules it can perform email with attachement, ect.
http://www.controlanything.com/ they even have wireless network type relays available now which allow you to plant them anywhere in the wireless area you'll have. I've actually mated this up with a PTZ which allowed the relay to move the PTZ to a preset based on triggers...ie. motion on camera #1, preset #3. ie. gate contact opens, preset #6. during specific hours you an also have emails sent, snapshots of cameras, ect.
