Her husband, Michael John Gregory, aged 77, is currently serving a 10-year prison sentence.
He was convicted at Portsmouth Crown Court in May this year, after pleading guilty to assaulting her at their home on the Isle of Wight in October 2013.
One of the police officers who was on the scene said he'd never seen injuries as serious as the ones she'd suffered.
In the video, Dawn says:
The last time he was punching me, I thought 'this is it', you're going to die tonight. I was thinking of my children, my grandchildren and thinking, if I could just get help, but if he does do it again, that's it...He just meant to do me harm, which he did, but I didn't realise how much harm, I knew my head was bleeding, basically, I was terrified.
People don't realise how bad these things are. But with that footage they can see how bad it was. A picture does tell a story but watching it they could see that I was totally confused...They could see the emotion of me and how frightened I was. And if anyone does see it, they don't want to feel like that If they (police) had left that night and that camera wasn't on, and it had been a little bit later, they wouldn't have found me as they did, they would have found a body.
Dawn said: "You've got a life, and you deserve that life."
Hampshire Constabulary’s lead on tackling domestic abuse, Detective Superintendent Ben Snuggs, said:
The effects of domestic abuse can be profound and persistent for the survivors, their families and the wider community.
We have the utmost respect and admiration for Dawn Marmoy and her decision to speak out and give strength to encourage other victims not to suffer in silence.
Hampshire Constabulary is dedicated to supporting survivors like Dawn to ensure they have trust and confidence in reporting their experiences to police.
This case provides a graphic insight into the power of Body-Worn Video (BWV) as an independent witness that captures crucial early evidence in an investigation.
Dawn's story, along with several other incidents recorded using BWV, is featured in this Panorama documentary.
