The transition to HD
I have replaced the back 4 "Cat Cam" cameras with 720p HD cameras. This means much clearer images. As part of this upgrade I'm also switching to some new software to provide the feeds.
By default when you go to the back cameras page, you'll see that the "Jpeg" button is selected. This will give you the most compatible mode which is a stream of jpeg images. The frame rate in this mode tends to be around 4 frames per second.
If you are running the Chrome or Firefox browsers, try the "Video" button, then click on one of the images. This will give you an HTML5 video stream that runs at about 10 frames per second.
The front cameras will be upgraded sometime during the next year, but will take more effort on my part :)
