Huh?  RG6 is almost invariably more costly than RG59.  Professional
installers have been using RG59 for CCTV systems for years.  If you
were using high definition (HDTV) cameras you'd need to use RG6,
preferably quad shielded. However, it is highly unlikely you'll find a
need for HD in a typical surveillance project.
