A Korner system costs $98 for a three-tag setup (converted, about £65). You can add additional tags for $25 each (a little over £15). After the first year, you'll need to start paying a $40 yearly fee to continue using the system (a little over £25). For more on the Korner Home Security system, check out our complete review.
