An Alberta man is sharing surveillance footage recorded outside his home that shows an apparent string of vehicle break-ins in his Edmonton neighbourhood.

Barry LeBlanc says he was shocked by the speed of the break-ins, estimating that the three thieves would get in and out of unlocked vehicles on the street in as little as six seconds.

"They were just going, rummaging through vehicles with their flashlights, and if they hit the jackpot they would just shut the doors and continue on with their flashlights," LeBlanc told CTV Edmonton. "You see them coming around the turn and checking every vehicle on the way down," he said.

LeBlanc said he installed the cameras about a year ago, after his vehicle was broken into.

"(I'm) still not smart enough to lock my doors," LeBlanc joked.

He said, this time around, the thieves made off with some change and a hunting knife, but they left a pair of glasses he said are worth around $300.

LeBlanc said the three suspects were each wearing backpacks.

"So it looks like they were just looking for things that were small but worth money," he said.

The break-ins have since been reported and the footage has been turned over to police.

Police in Edmonton are warning that vehicle break-ins typically increase this time of the year.

Sgt. Rowan Jennings says keeping car doors locked can make all the difference.

"Then the person actually has to work to get into the vehicle, and…maybe draw attention to themselves, which is the last thing somebody wants if they're going to commit a crime."
