Strange 'Elf' Captured on Security Camera?

A strange video has surfaced purporting to be from security camera footage which captured what appears to be a creature resembling “Dobby the Elf” from the Harry Potter film franchise.

A woman calling herself “Vivian Gomez” published the video on Facebook on June 6th, writing, “So I woke up Sunday morning and saw this on my camera and am trying to figure out...what the heck?? First I saw the shadow walking from my front door then I saw this thing....has anyone else seen this on their cameras?? The other two cameras didn’t pick it up for some reason.”

The clip has been shared and tweeted extensively and has over 5 million views. Speculation is rampant that the video was faked, based on inconsistent shadows, strange movement, and evidence of editing. Others have also guessed that the clip shows a puppet or a child in a costume.
