The time lapse video is automatically generated each night and then downloaded to the web server. It’s kind of fun to see how much can be done with limited bandwidth. The is dial-up has a data rate of of 56k baud and usually connects a bit slower than that. The camera is set up to take 4 images per minute x 60 min/hr x 12 hrs = 2880 frames in a movie.
The upload file is more than 10MB and the whole process takes a about 5 hours to complete. Think about the mars rover. It operates remotely (very) and does not have broadband comm back to earth. Looking it up I see the maximum downlink data rate from a rover is 11060bps or 11.06k. Our dialup is 56k. So, if they can do with 11k I think we can do ok with 56k.
Below is an example of a Sebec Lake Webcam time-lapse video. Go to www.SebecLake.net for the latest daily update.
