Some domestic abuse victims could have security alarms fitted in their homes as part of a £2.5m package of extra funding.
Officials say victims in Gwynedd could have home safety devices, so that they do not have "seek refuge elsewhere".
Eighteen organisations which support victims will receive the extra money, on top of £4.3m already committed by the assembly government.
Social Justice Minister Carl Sargeant said the groups' work was inspiring.
The money will go towards facilities and support for victims and their families.
Groups in Anglesey and the Vale of Glamorgan will use the funding "to run perpetrator programmes to rehabilitate offenders and help them rebuild their family life".
Mr Sargeant said: "Domestic abuse affects all members of the family, from the person on the receiving end to the children who witness violent behaviour.
"No-one should feel threatened or scared in their own home and I am committed to supporting victims in everyway that I can.
"These organisations work tirelessly to take victims out of harms way and help them to rebuild their lives. Their work is inspiring with so many innovative approaches to tackling domestic abuse, such as installing safety devises which allow victims to live in safety in the comfort of their own home."
