The front cameras are up and running in HD. However there will be some additional down time to fix some remaining technical issues.
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 :)
I'm currently working on replacing 3 of the front cameras. The old ones were failing. They were actually board cameras which lasted much longer in the elements than I expected. The new cameras are designed for outdoor use and include infrared for nighttime viewing - much like the back cameras.
Update: The front door Cam is up. The other two will return in the next couple of days.
Update #2: All cameras are now up and running.
To make my photo collection easier to navigate, I am now hosting them on smugmug. You can still click the photos button above, or go directly to http://ngcard.smugmug.com.
If you are using a phone or tablet, you can also download the smugmug app and add the user 'ngcard'.
