Eerie CCTV footage appears to show a man trying to break into a house.
The man tries the handle of the door of a home in Citywest, Dublin to see if it was open, before making a swift exit.
One of the many doors that he is alleged to have tried in the area belonged to resident Ross Dunne.
Ross told Dublin Live : "He tried our door at 3.30am on Sunday the 28th of April.
"We live in an estate in Tallaght. My wife was feeding our four-week-old baby at the time and we knew nothing about it until a neighbour messaged me at 8.30 the next morning to say his cameras caught someone trying his door at 4am.
"When I checked mine, I realised the same guy was at my house 30 minutes earlier and was clearly just checking for unlocked doors, complete opportunist.
"We had issues in the estate with things being stolen from cars, but again they always only get into the unlocked cars. Obviously an easy fix here is to ensure you lock your doors.

"We were lucky that we remembered to lock our door though. We could have easily forgotten as we are a little sleep deprived at the minute with the baby."
Ross contacted gardai and passed the videos onto them.
He added: "Gardai came up to the house and we emailed on the footage, but they didn't recognise him.
In a statement to Dublin Live, a spokeswoman for the gardai said "they attended an incident of public order at a premises in Tallaght".
"A male had been seen by the occupant of the house, trespassing on the grounds of this property, on the 28 April at approximately 3.30am."
