After a 71-year-old woman was murdered in her home, her Sandy Springs community is taking a step to protect their neighborhood.

Signs at the front of Derby Hills subdivision in Sandy Springs warn that the community is under video surveillance. For now, home-surveillance are the primary means of video surveillance, but that’s changing soon. The community is purchasing a video surveillance system that will track every car tag that enters the community.

“I think a lot of people are installing cameras in the homes, upping security systems,” said Ellen Sullivan, who lives in the subdivision.

The move comes less than three months after their neighbor, 71-year-old Kay Thomasson, was stabbed to death inside her home here on Old Woodbine Road in June.

Her own camera caught the suspect roaming outside her home. Sandy Springs Police are still looking for the killer. They are offering a $100,000 reward.

“It's horrible for a neighborhood to go through this,” said Ruth Laws. “It's really a shock to all of us,” she added. Laws and her husband have lived in Derby Hills since the mid-60s. They donated to the community camera system. “We hope to keep some people out and we hope that the friendly people will come in because it’s a beautiful neighborhood,” Laws told CBS46.

Homeowners say the cameras may not prevent actual crimes but they’re hoping it will deter them.

They’re hoping this will help them be better partners with police. “I understand that it gives them instant data and as I understand, there is new technology in the police department where they can immediately scan those license plates and get that information to find people,” Sullivan said.

Police are still looking for a suspect in Thomasson's death.
