How mathematical DORI optical calculations beat an $18,000 alarm installer proposal — saving $9,400 while achieving complete perimeter detection.
The Harrisons built a custom 5,100 sq ft home backing onto a desert wash in North Scottsdale. A local security sales company quoted them $18,000 for 14 cameras. However, an inspection of the plan revealed that cameras were placed purely where power conduits were easiest, leaving a 45-foot unmonitored blind spot along the wash.
Furthermore, standard 2.8mm wide-angle lenses were spec'd for a 90-foot driveway, rendering license plates completely illegible.
The Harrisons achieved 100% gapless perimeter coverage using only 8 cameras instead of the 14 proposed by the installer—saving $9,400 in equipment and wiring costs.
Their property defense rating increased from 34/100 to an outstanding 96/100.
The Camera Placement Planning blueprint was like having an architect for our security. We saved nearly $10,000 and ended up with a far better layout than the big-box installer designed.
