The result of the 2017 SDM 100 was upbeat: Collectively, the industry’s 100 largest security dealers grew their recurring monthly revenue (RMR) 18.4 percent, from $612 million to $725 million, last year.

It’s used in many different ways by different people, but the primary objective of the SDM 100 remains the same after 25 years: to measure consumer dollars gained by alarm companies, in order to present an account of the size of the market captured by the 100 largest security providers.

In 2015 we celebrated the 25th anniversary of the SDM 100 and honored eight companies for being ranked on the first SDM 100 Report in 1991 and all of the reports thereafter.

The security industry looks to the SDM 100 — a group of 100 of the largest security companies ranked by their recurring monthly revenue — as a wellspring of industry trends and operational best practices. So, which manufacturers and distributors are behind the SDM 100, supporting them with the products, solutions and services that have helped make them successful?

Most of the largest security dealers in the industry confirm they were on solid footing in 2014, and their 3.8 percent aggregate growth in RMR proves it. But for many dealers, new competitors are too close for comfort.

The 2014 SDM 100 ranks U.S. companies that provide electronic security systems and services to both residential and non-residential customers. This ranking is based on information provided to or, in few cases, estimated by SDM. Ranked companies were asked to submit an audited or reviewed financial statement, or a copy of their income tax return.

World Wide Security & GC Alarm Inc., ranked No. 73, concurs there was “greater demand for security services and an increase in budgets to accomplish security goals.” The company, which logged a 3.2 percent increase in RMR, notes the best growth areas were video and managed services.
