Detectives said they wanted to talk to a man seen in the video, but did not call him a suspect.
"Somebody that's going to be casual enough and confident enough to go into a residence when somebody is there and they know they're there, we feel like they may be connected," Cary Police Department Capt. Michael Williams said.
The thefts happened in Cary's Lochmere neighborhood.
Residents reported televisions, purses, wallets, electronic equipment and jewelry stolen from their homes. No one was harmed during the burglaries.
"Completely violated knowing that somebody was in your home and walked around your home, knowing you were upstairs and your children were upstairs," victim Tracy Roberts said.
The Roberts family is one of three in Cary that have been robbed while they were sleeping. Roberts says her husband made the discovery Tuesday morning.
"About 10 minutes into being downstairs he realized that the window was open, the TV was gone and then he looked around," she said.
Roberts said they noticed several other electronics were also gone, including a camcorder with video of family holidays.
"The material possessions you can replace, but it's the memories you can't replace," she said.
Police are warning residents to keep all doors and windows locked to help prevent these kinds of thefts. They also want residents to call if they see suspicious or idling cars in neighborhoods - especially at night.
The Roberts family says it is taking extra steps to enhance their sense of security.
"Now the window treatments will go up and the alarm system will go in," Roberts said. "I don't feel particularly safe, but I probably have one of the safest homes in Cary, because there's nothing left."
Cary police have stepped up patrols in the Lochmere and Highland area.
There's also talk of a meeting next Tuesday to address the concerns of residents.
