I know it's possible but...?
A couple of suggestions:
1. From what I know, Trendnet only offers PoE switches and and access points but no routers. Unless your modem supports handing out multiple IP addresses, you'll need a router that does DHCP and NAT, else the cameras cannot be reached via the Internet.
2. A further problem is is that only one camera behind the firewall can be reached. It appears you need a server on site that provides you with a public interface (i.e a web server) that allows you to select which camera you want to watch remotely (and possibly at the same time records what all cameras see). Their software makes heavy use of ActiveX controls and only runs on Internet Explorer (see demo at http://www.trendnet.com/VideoIPHelper/de mo.asp -- be prepared to deal with potential firewall issues).
