We're still in the design phase of our new build, but have received some preliminary bids for the construction. We plan to pre-wire for low voltage - cameras, A/V, internet etc. But there's another line item for security: $5500 for prewire, contacts, key pad, glass breaks, etc. It seems that there are more and more wireless systems out there that would be a fraction of this cost. Is it worth it do pay more for the wired security? And any recs for good wireless systems if that's the way to go?
