The video, which has since been uploaded to YouTube, was filmed using a doorbell camera.
At the start of the unsuspecting clip, nothing appears out of the ordinary.
The camera is filming from the front door of a house and is looking out onto the street.
At 47 seconds into the footage, a creepy voice appears to say: “I’ll kill you.”
Paranormal YouTube channel Haunted AF uploaded the video only days ago with the caption: “Ghost Caught On Ring Says ‘I’ll kill you’.”
One viewer wrote: “I heard it. To me, it sounds much different from all the wind noise you hear before the 47-second mark.”
Another wrote: “I suggest burning your house to the ground and running as fast as you can.”

It’s not the first time a “ghost” has been caught on camera.
Weeks ago, a couple filmed “ghost’s feet walking” during their stay in a haunted house.
And one mum was convinced of ghosts existing after making a chilling discovery on a baby camera.
