Are these Sydney's dumbest crooks?

Security pictures show two men trying bizarre ways to break into homes at Little Bay.

While the Notaras family slept inside their house, surveillance cameras caught two men moving straight to the dog door.

“They didn't care, they took off their hats and looked at the camera as well,” Tania Notaras said.

“We thought it was perfectly safe, they tried so many different ways to get in head first, then with the feet first and then arching the back,” she said.

After half an hour, the men gave up and smashed a window instead, stealing a computer and handbag from the kitchen.

“That worried me a bit because, if they had someone who was a bit smaller than a child… [they would] be able to squeeze through that door quietly, unlock the doors and let a whole bunch of people in of they wanted to,” Tania said.

Tania’s daughter Natalie said the home invasion made her ‘really nervous and really scared’.

Four homes in the street have been robbed within a week.

Resident Colin Vickers recently installed surveillance cameras, which did little to deter the thieves.

“It’s taken away our sense of security to know someone was just outside my door watching me while I was working early in the morning,” he said.

“By this vision, those who wish to commit crimes will go to lengths they can to try get inside the premises, so that's why you need to think about all those avenues around the home where people can get in,” Chief Superintendent Brad Shepard from the Crime Prevention Unit said.

The Notaras family now locks the dog door at night, but the family is considering talking it out altogether.

“We've had dogs for 20 years, but I'm scared about that dog door now and don't know if I want it there anymore,” she said.
