Hi-Def San Francisco is project of CloudView Photography. The camera is a 3 megapixel StartDot Technologies Netcam XL mounted in a weather proof enclosure high in the hills of Sausalito. Images are captured every 15 seconds cropped from the full resolution to 1920×1080 and uploaded in 480, 720 and 1080 resolution to the web server. Periodically the software (running on a FreeBSD server) creates a time lapse that collapses the prior 24 hours into 240 seconds of video.
