NIAGARA FALLS NY-- The City of Niagara Falls Police Department wants to catch more criminals, by catching them on camera.

Mayor Paul Dyster and other leaders announced the plan to put up seven surveillance cameras around the city by the summer.

Three are going up along Pine Avenue, where police say there's been more crime recently.

They won't have people watching them 24 hours a day, but they will give investigators video to work , and leaders also hope they'll be a deterrent.

"Perpetrators don't necessarily know where those cameras are located, they don't know what their reach is, and they may think twice if they think an image of their face or maybe the license plate of their vehicle is likely to turn up in evidence against them," says Dyster.

Niagara Falls already has three cameras and the District Attorney's office is donating four more of them.
