Certified Alarm Distributors is a leading low voltage supplier in the tristate area; independently owned, and operated since 1976.

Our story began during WWII. Kalman Drebin, founder of Certified Alarm Distributors invented the concept of 'Radar Technology' for the US Army. His career continued as an engineer for the Bulova watch factory. Using the technology of Radar, Mr. Drebin founded his own company called 'Radar Sentry' and installed the first motion detector, used to deter buglaries in a friend's factory. Through word of mouth, his installation company grew, employing 30 installers. He took in anyone who needed work especially young men who had a hard time sitting in school. He taught them a trade for life. He encouraged them to compete against him and open their own installation  companies.
