For those who are interested in this sort of thing: My website and home network are managed by OS X and a Linksys router. I put in most of the cabling (the so-called physical layer) myself. The wireless legs of the net run through an old Airport station (the original gray model) and two Linksys WAP-11 wireless access points. (Though you wouldn't know it from the sorry documentation, these devices are a breeze to configure with a Mac.)

The adobe walls in the house make it necessary to have two wireless zones for full coverage. One is served by the Airport, the other by the pair of WAP-11s. The first of these units acts as a bridge, relaying signals from a network camera, an Axis 2100, to the second unit, which is connected by cable to the router upstairs. (Unfortunately, you cannot yet do this with Airport stations.)

The Axis cameras are amazing devices, each with its own built-in webserver. You just assign the camera an IP address, configure it through a browser and off it goes, uploading images (with the FTP protocol) to your server. (The documentation here is also wanting but once you thrash through to a solution it all seems quite simple.) You can also get the Axis to send you an email every day -- or every hour or every minute -- with a picture attached. You can even set up the camera to dial up your Internet Service Provider to mail the pictures.

The whole system is connected to the Internet through an ordinary DSL line with a static IP address. The Web site runs on Unix Apache software, which is included as part of OS X.
