Footage from a police officer's body worn camera was shown for the first time in Tasmania in a Supreme Court criminal trial on Monday.
Crown prosecutor John Ranson submitted the footage shot by Constable Glen Dawson in the rape trial of a 33-year-old Launceston man.
The footage showed a contemporaneous account by a 33-year-old female complainant about her allegation of vaginal and anal rape on June 15, 2019.
The man, who cannot be named for legal reasons, has pleaded not guilty.
Constable Dawson said that body worn cameras were activated by pushing a button twice although vision preceded audio by about 30 seconds.
In his opening address, Mr Ransom said the defendant and complainant had been in a nine year on-again, off-again relationship which ended in April 2019.
He said that man appeared intoxicated when he arrived uninvited at the woman's residence.
In a video recorded interview with Detective-Constable Sarah Campbell the woman said the man grabbed her from behind in a bear hug and pushed into the bedroom.
She said he yelled abuse at her and called her a slut.
"I don't want nothing to do with you," she told police that she had said.
"I was begging for him to stop and I tried to push him off but I just couldn't." she said.
She said she had howled and cried with pain after he entered her "back passage".
Detective-Constable Campbell also interviewed the defendant.
Under cross examination from defence counsel Evan Hughes she said that after the video interview ended the man volunteered: "I did have consensual sexual intercourse with .... but my penis slipped and went into the wrong hole."
The statement's admissibility, because it came after recording equipment was turned off, was subject to legal argument.
Justice Michael Brett ruled it admissible.
