Signal Service

In 1976, Wilbert Wilson started a small alarm company in Murphys California; today Signal Service is the largest family owned alarm company throughout the Sierra foothills. Owned and managed by Wilbert's three sons, Andy, Mark and Will who have made Signal Service the success it is today. We have 45 years of proven experience partnering with our customers to bring them the best in the security industry. From installation to service to ongoing inspection and maintenance; we hire, train, and develop our own employees.

Signal Service began in the small Sierra Nevada Mountain town of Murphys, California but over the past 45 years has expanded throughout all Northern California. We measure our success by the quality of our relationships and the service we provide our customers. Our professional team has years of experience, and as a family business, you still receive warm and friendly service.
