Bay Alarm, ranked No. 13 on the SDM 100 with $7,781,772 in RMR on Dec. 31, 2013, announced that it acquired SDA Security, a family owned and operated alarm company in San Diego.

SDA Security has provided security services to the San Diego and Inland Empire markets for over 80 years. Founded in 1930 by Harold Eales, the company has done well under three generations of family leadership. Throughout the past eight decades, the Eales family has focused on building their business on the foundation of personal relationships and outstanding service.

With this purchase, Bay Alarm will expand its presence in the San Diego and Inland Empire markets. In addition to their suite of security products, Bay Alarm also offers 24/7 alarm system monitoring by their locally staffed employees.

This acquisition ensures that both Bay Alarm and SDA customers continue to receive the same great customer service they’ve come to know and expect, whether they reside in Northern or Southern California.

Matt Westphal, co-president of Bay Alarm Company said, “Over 80 years of dedication to the security of the San Diego community, the Eales family has built a company that closely matches the customer and employee-focused culture of Bay Alarm Company. The Westphal family is excited to continue their mission while expanding Bay Alarm’s 30 year history in the San Diego marketplace and bringing new technologies and processes to the SDA customers.”

With its focus on business security products and services, SDA Security adds strength to the existing business and residential solutions offered by Bay Alarm. This merger of two complementary companies supports Bay Alarm’s commitment to ensuring that local communities are safe, protected and well educated.

“The security industry is advancing at a rapid rate,” said Shandon Harbour, president of SDA Security. “As we researched how we can best prepare ourselves to continue providing cutting-edge services and products, it became clear that joining the Bay Alarm family would ensure our customers have continued access to services they need. We know that Bay Alarm would be the right choice for future growth.”

Both Bay Alarm and SDA Security share a long-time business partnership with NetOne (formerly Security Network of America), a network of independently held alarm companies across the nation with a 25-year heritage in the commercial and home security field.  This shared partnership helped lay the foundation for this acquisition.
