Jason Good, from Henrico county in Virginia, US, was caught by his wife after he used his cell phone to record his mother-in-law taking her clothes off, said the Daily Mail.
His wife was horrified to discover the footage taken at their home in Laurel, Virginia, was of her 57-year-old mother.
She phoned the Henrico county police after finding the tape.
Police found a hole in the wall between the garage and the bathroom, and arrested Good.
If found guilty, Good could face up to a year in prison or a fine of up to $2,500.
His mother-in-law, who was filmed, does not live with the couple.
