 Once a minute a picture is uploaded to the DCARA VPS. Once an hour, a cron job will rsync all photos from the hourly directory to a server on Guinn Hall (the "Fog Server"​),​ which will then compile the pictures into a timelapse and upload them to the VPS. Every morning a similar process is repeated for the daily timelapses, and every Sunday it is repeated for the weekly timelapses. Once a minute a picture is uploaded to the DCARA VPS.

 The Pi is powered via ethernet. On some designs a simple device is used to pull the power pairs from the Ubiquiti PoE standard and feed those to a 5v switching DC buck. In other designs a 48v PoE to 5v adapter is used. By regulating in the camera box, line loss over a long CAT5 run can be compensated for.  The Pi is powered via ethernet.

-The camera is mounted on standoffs inside the box. A hole is drilled to allow the camera to see out of the box, and is covered by a UV filter. The filter is sealed with RTV. See [[http://​vps.dcara.net/​rosston/​:Rosston]] for a picture of the box. +The camera is mounted on standoffs inside the box.
