Watching a double webcam feed from Safari on my iPad, while controlling the Raspberry Pi using Panic Inc's SSH application Prompt was kind of fun! As you might guess from past blog posts, I was trying (several) Microsoft Live Vision USB webcams , with the aim of using them via the RPi and a long ethernet cable to monitor my bird nesting box cameras . My plan (outlined back on this post ) is to use power-over-ethernet (POE) to supply 5V to the Raspberry Pi , which will be down the garden within USB range of the birdbox or birdboxes.
