SEM Security Systems has been using DSC brand panels and components
since 1998. While we have tried other panels, we have found the DSC line to
provide reliable service with all the features that are necessary for an easy to
operate alarm system. With that said, the panels featured below are DSC
panels but if your requirements call for some capability that DSC dosen't
offer, we do work with other manufacturers.
