Lindsay Holman has been found to have stored 1,500 depraved photos and 20 videos on five devices at his home which he shares with his wife in Haddington, East Lothian.
Holman, 64, was at home with his wife when police raided the property armed with a search warrant last year following a tip of indecent images of children being uploaded.
He denied any involvement in possessing the disturbing material, but was forced to admit guilt after devices including his mobile phone and computer were examined by experts.
The recently retired IT manager was arrested and charged and he pleaded guilty to two counts when he appeared in Edinburgh Sheriff’s Court last month.
Holman is listed online as a former director of engineering development company Televisua Ltd and is also listed as a former director of Panasonic.
He returned to the dock to be sentenced and was placed on the sex offender register for three years.
Sheriff Kenneth Maciver also placed Holman under the supervision of his local social service for three years and ordered him to perform 225 hours of unpaid work.
Defense agent Peter O’Neill told the court that Holman “had an interest in adult pornography” but got involved in “a [online] group where all kinds of pornography was shared”.
Mr O’Neill said the perv’s family were ‘shocked but supportive’ after his arrest.
Earlier, the court was told that police arrived at Holman’s family home with a search warrant on May 25 last year after receiving intelligence footage uploaded to the property.
Prospector Anna Chisholm said officers raiding Holman’s home on a warrant discovered 1,500 images including 130 images that would be classified as Category A – the worst end of the spectrum.
Holman pleaded guilty to possessing indecent images of children in his home between August 20, 2016 and May 25 last year.
He also admitted to being charged with permitting the taking or making of indecent images of children between the same dates.
