A man named Chris posted footage from a camera at his front door to the Texas-based paranormal podcast (audio story) site Haunted AF.
According to Chris, this camera turns on when triggered by motion, and some time ago it started turning on every night at about 3 o'clock. There was no one on the recordings.
But one day, when Chris was watching another blank night video, he thought he heard a human voice. When he made the sound louder, he was horrified: the disembodied voice clearly said the phrase "I'll kill you".
Turn the volume up to full to listen to the recording. The phrase "I'll kill you" can be heard at around 0:24, but invisible attempts to say something else can be heard throughout the recording, only the words there are almost impossible to make out.
According to Chris, when these strange nighttime camera triggers started, he initially thought it was just a technical glitch. But one evening, everything changed.
None of the people can be seen in the recording, however, after 5 seconds, something like a translucent whitish ball-orb appears in the frame. The ball floats to the left and disappears.

True, it is not known whether this orb is associated with a threatening voice; it may be just a fluff caught in the frame or a speck.
According to Chris, he still continues to live in this house, while his security system soon after this recording was completely cut off and until he debugged it.
