Anne Bertrand's office has posted guidelines for video surveillance, outlining where cameras can be installed and how the information gathered must be protected.

The privacy commission doesn't have jurisdiction over private institutions. But when Bertrand heard about a case at the Fredericton YMCA this week where a video camera was hidden in the men's locker room, she wanted to wade into the resulting discussion.

"Cameras cannot be a covert operation, cannot be anything secretive about it," said Bertrand.

"It's not intended to spy on people.

"I think that is why the reaction has been vociferous about it.`Oh, there were cameras at the Y and we didn't know about it?'" she said.

"People need to know about it."

The Fredericton YMCA informed the police about the camera in the locker room and the case is under investigation.

Coincidentally, Bertrand's office has posted best-practice guidelines for video surveillance. It includes a step-by-step guide on where cameras can be installed and how the information gathered must be protected.

Bertrand's guidelines state cameras should never be used to monitor areas of privacy, such as washrooms and changing areas.

Bertrand said placing a camera in such a location in order to deter thieves should be done as an "absolutely last resort."

"Really a golden rule — do not use cameras to view into private areas," said Bertrand.
