Ghostbusting used to involve walking round New York in odd boiler suits and ducking green slime.
Sadly, the web has made remote spook-seeking possible and now web surfers can look for spectres online.
This camera keeps an automated eye open in a former Belfast mill for the ghost of Helena Blunden, a young linen worker who died in 1912.
A disused printer starts working and faces appear before the camera according to easily confused visitors.
You can even listen to audio files of the sound of ghostly footsteps.
