The Story of RHR Systems begins in the 1950s post world war II era when, Reice Hamel, a Grammy Nominated Audio Electronics Engineer, developed the first Remote Recording Studio. Magnetic tape recorders, video cameras, alarm security, telecommunication systems, and custom audio were the systems that he designed and integrated into his mobile unit. These systems were used for his client base of legendary record companies and entertainers.


Today, RHR Systems dba Trend Systems Group, is a C-10 electrical systems contractor specializing in custom engineered systems for commercial and residential applications.


I carry on my fathers legacy by providing solutions for today's demanding building requirements. The current construction market requires the Low Voltage Systems Contractor to be experienced with the convergent systems that we are all now so familiar with.


No matter what your needs are, Fire Alarm, Security Alarm, Access Control, Audio & Video, Voice & Data Networks we have the technical and construction experience to complete your project on time and on budget.
