DY Security & Technology, LLC was established in De Pere, WI, in 2007 by Dan Young. We began as a Brink’s Home Security authorized dealer, then transitioned through Broadview Security, and we are now a member of the ADT family. Our security system integrations have expanded beyond burglar alarms. We can custom design systems to meet our customers’ needs in fire alarms, access control, surveillance, CCTV, medical monitoring, and much more. Our office is located in Green Bay at 2701 Larsen Road, in the Business Development and Manufacturing Center.
