A 64-year-old man accused of five charges of voyeurism and one of administering poison appeared before magistrates in Bury St Edmunds on Monday.
James Leonard Smith, of Boundary Road, Chatham, in Kent, is accused of setting up a camera in the bathroom of a home in Suffolk and recording the private acts of two women and three children.
Prosecuting, Andrea Reynolds said that Smith subsequently watched the recordings for the purpose of gratifying himself sexually. He is also accused of giving a glass of urine to one of the voyeurism victims.
Smith did not enter a plea and was released on bail with conditions not to contact the alleged victims or enter Suffolk, except when attending court.
He is due to appear at Ipswich Crown Court on March 25.
