Seems like someone should make a wifi security cam that has several hours worth of internal storage to cache video when wifi is unavailable. Storage is cheap is hell. A 4GB micro-SD card adds like a dollar to the cost of a mass produced embedded system and could save a few frames per second for hours.

That's exactly what the cheap wifi security cameras do. They capture the video on onboard microSD cards and wifi is only for viewing of that data. If you loose wifi, it will still record.
