Rancho Santa Fe Security Systems was founded in 1978 by Myron Mueller to provide superior security services to the Rancho Santa Fe area and surrounding communities. Over the years, there have been many changes in the security industry. Some changes have been positive, such as the vast improvement in security technology. While other industry changes have not been as positive, such as the lack of customer service resulting from the multiple mergers and acquisitions by enormous consortiums interested more in the financial bottom line than providing true peace of mind.

At Rancho Santa Fe Security Systems we have maintained a focus on providing superior customer service for our clients. Since 1978 we have added many valuable services for our customers. Our services include our own local dispatch, 24 hour service department, armed alarm response, long-range radio-frequency back-up monitoring.
