The residents who would not be safe will wear a wrist-band, similar to a watch, which makes the door self-lock.
"The door will open for those who don't need the secure [solutions] . . . the wrist band is unobtrusive and won't be heavy. It can't be cut off," Mrs Jeffs said.
The monitoring software will also let the nurses know when residents are in the communal lounge or their whereabouts in their own home.
In every home, a sensor will be installed alongside each bed, alerting staff when a resident gets up in the night, and depending on the resident the staff will respond immediately.
Mrs Jeffs said the technology would ensure quality of care, while giving all residents the ability to move around the facility, "so they can be involved in daily life and safer in their environment".
The technology was developed by communications technology experts NCS.
Mike Dillon, director at NCS, said the technology all came about from the clients' needs.
"Nurses can respond a lot quicker, and it can prevent a lot of falls and accidents."
Mr Dillon said he had enjoyed the project.
"What [Whare Aroha Care] are doing is totally different from anything anyone else is doing in New Zealand . . . it's great to see, it's been a challenge."
The team at NCS were "absolutely amazing", Mrs Jeffs said.
"I have so much faith in their ability . . . right from the beginning Mike knew what we were trying to do."
Mrs Jeffs said it was exciting to have the dream actualised but there were nerves in getting everything ready in time, especially as the opening had been moved from October to August.
The dementia-friendly village will be the first one to open in New Zealand, and the first of its kind outside of the internationally acclaimed De Hogeweyk in the Netherlands.
