Some Kensington neighbors are on edge Tuesday night after strange encounters in their front yards.
The community is so worried, some residents are increasing security measures to their homes.
One woman had a man scratching at her back door at 2:30 a.m.
Another neighbor says a man nearly walked into his home in broad daylight.
Skip Motsenbocker and his wife had a strange visitor at their home a few weekends ago.
"The guy standing here just like leaning against our gate just staring and peering into our backyard. It's weird and creepy," Motsenbocker said.
His wife called police while he went outside to make sure the man left.

"He was parked outside of our gate for almost four minutes just kind of waiting for passersby to go by and then just casually got up, opened up both locks on the gate like it was just nothing," he said. "He walked right in and you could actually see him reaching for the door handle like he was just going to walk in."
Motsenbocker has surveillance video around his home and believes the man had ill intentions.
Fast forward to last weekend just a few blocks away.
Jen, who didn't want to be identified for safety reasons, got up in the middle of the night to use the restroom when she heard some scratching at her back door.
"And as I'm standing here, I see a man walk by, and it scares me and I go to the window and I start hitting the window and the man comes back, and puts his face right in the glass. And I'm yelling at him and screaming at him, 'why are you here? Get out of here!'" said Jen.
The man left, but neighbors are concerned.
"Kensington has always been such a safe little neighborhood. We love it here," Jen said.
"It's a little disconcerting knowing that there's people wandering around lurching just kind of looking for a crime of opportunity," she said.
San Diego police advise residents that if they think someone is trying to get into their home, they should call 911.
They also recommend neighborhood watch programs.
