Parks officials said Wednesday night that the first step in determining whether video surveillance cameras should be installed at Waveny is to get a formal, detailed opinion from local police. An online petition with more than 1,400 digital signatures that advocates for the cameras and data on how such security systems benefit the public are “very important pieces” of the discussion, Parks & Recreation Commission Chair Rona Siegel said during the appointed body’s regular meeting. And a “recommendation from law enforcement to the town, presented to Parks and Rec is the correct step,” Siegel said at the meeting. “A clear and concise opinion from law enforcement” that includes recommendations on just where the cameras would go “is what the town needs,” she said at the meeting, held in Town Hall. Other questions such as what local agency or agencies would have access and jurisdiction over video content and how long it would remain before officials taped over it also must be part of the town’s decision, officials said.
