Just an old guy with some IT experience and a burgeoning surveillance system. I've lurked around here for a while an have corrected the mistakes I've made in the past by buying based on price and, alleged, performance offered by vendors and manufacturers. Money wasted, lessons learned.
From another old IT guy... You learn the lesson the hard way, But most of us have made the same type of mistake.
