DSC is very popular with do-it-yourselfers. The tutorials on the site are built around the DSC PC1616, PC1832, and PC1864. All three panels share the same programming and installation procedures, their differences lie mostly in the number of zones they're able to accomodate. The PC1616 has six on-board zones, with a maximum of 16 hardwired zones through the use of zone expanders. It also has the ability to support up to sixteen wireless zones. Both the PC1832 and PC1864 have eight on-board zones, expandable to thirty-two, but the PC1864 has the edge in wireless capability, sixty-four wireless zones as compared to the thirty-two available in the PC1832. Which is best for the do-it-yourselfer? I'd lean towards the PC1832, but the PC1616 is more than capable for the vast majority of installations.
