Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers


"The Axis 2120 is a networkable camera running an embedded version of Linux for Etrax CPUs. A complete OS for a camera may seem like overkill, but there's a lot more going on here than taking pictures: this device is running an embedded web server (Boa , which has a source tarball of under 100k), is capable of sending pictures via ftp, can handle incoming ftp connections, and has an alarm mode allowing it to take pictures and mail notifications based on motion. Unlike it's much less expensive cousing, the Axis 2100, the 2120 seems very sturdy and durable as it's housed in a metal case, though Axis warns that enclosures are required before operating the camera outdoors."

"All of this is packed into a camera 2.24" tall, 3.39" wide, and 5.43" long. It sports an Etrax 100 32-bit RISC chip, 16MB RAM, and 4MB of flash RAM (2MB of which is available for user-designed HTML files for its server.) According to Axis' documentation, the camera's maximum resolution is 768x494 at 24 bits color and can reproduce motion at a maximum of 30 frames per second."

"The camera is clearly packaged with Windows users in mind, but it includes directions for UNIX-based systems. To get it running with a Linux machine, all that's needed is a pair of commands (arp and ping) plus a peek at the camera's serial number, since the MAC of the device for the arp command is derived from that. Once the camera is talking to the rest of the network, visiting it with a browser gives the user access to a web-based setup page that includes a more detailed setup wizard and a set of general configuration options."
