Wow, that's pretty pricey! :0 :(

I wonder if the University of Southampton tech will ever be productized... It sounds just like science fiction.

There are already some Kickstarter projects that offer "life cams" but I don't know what the quality and the capacity are. One way to deal with it is to make the storage selective - just keep a high-speed, high quality buffer loop going and have a "capture" button that lets you archive only the last minute or two once you notice something that you want to save.
