Appearing to hold something in his hand he then waved it over a silver car on the drive.
The man then walked away and did the same over the back of the vehicle.
He then wandered off down the street as the 14 second video came to an end.
The man was spotted allegedly doing the same thing up and down the road.
It happened at 10:30pm last Friday (23 Jan), in Southall, west London, as reported on Need To Know.
The homeowner – who wished to remain anonymous – alleged: “This suspicious individual was caught on camera walking up driveways in Southall.
“With potentially a signal relay device in his hand, trying to scan for keys to unlock vehicles.”
He advised homeowners to put their car keys in a signal block pouch or metal tin.
“Don’t leave keys near the front door or hallway,” the resident – who didn’t report the matter to police – said.
One local – called John – said: “And the police aren’t in a position to do anything, to track him down?”

Fadia added: “Get bollards put in at the beginning of the driveway.”
Dave joked: “Personally I believe if he has a scanning device it needs placing where the sun doesn’t shine.”

One said: “Yeah he is trying to pick up signals.”
