You can certainly record full face non-blurred images. Otherwise the recording would be almost useless. There are requirements for secure storage and disclosures. The blurring is required if the video is shared/published. So for example if there you request footage of yourself for whatever reason, and others are present in the video, they would have to be blurred. There are also other use cases for patients in medical facilities etc.
Doubtful, this takes lots of work. Sighthound spent serious money/dev time on the face/person/object recognition. I dont think he is capable of something like that on his own and more importantly, its of little use to his base.
