To enhance public safety, the village of Lemont, Ill., recently installed a municipal networked security system. The system integrates wireless video surveillance with broadband communications, allowing first responders to send high-speed data and streaming video over a licensed 4.9-GHz frequency. “Keeping Lemont’s community, citizens and visitors safe and secure is our top priority,” said Lemont Chief of Police Kevin Shaughnessy. Municipal broadband networks can integrate public-warning devices (such as sirens or tone-alert radios), first-responder notification (ranging from text alerts to telephone messages) and communications infrastructure (4.9- or 2.4-GHz frequencies and 900-MHz data networks).
