The text alert service is a joint initiative between community members and gardaí.
It sees gardaí issue a text message to those who've signed up in the event of suspicious activity in the area.
Sinn Fein Councillor Pat Fitzgerald told WLR News that the scheme has been well received.
"It's the community doing something for itself about it's own security," he said. "People are very supportive - we gave ourselves 3 months to get 300 names and within the first 2 weeks we had well over 1 hundred.
He says that the type of crime they're trying to combat isn't just a rural issue.
"I always suspected that it was rural people that were most vulnerable, but we're finding people even in the village of Dunmore East that are also worried."
Callers will be visiting households in the coming weeks with registration forms.
