🏡 Home Security Planner
Enter your floors, exterior doors, ground-floor windows, and garage to get a recommended count of cameras and sensors, plus an estimated hardware cost.
🔒 Layout & Coverage
What is a Home Security Planner?
It turns a few facts about your home — floors, doors, ground-floor windows, and garage — into a sensible starter system: a recommended number of cameras, door and window sensors, and motion sensors, with an estimated hardware cost including a hub.
Use it to scope a DIY or professionally installed system before you shop — the results are estimates for planning, and a security pro should confirm coverage on site.
❓ Frequently Asked Questions
How many security cameras does a large home need?
It depends on the layout. This planner recommends cameras to cover the main entry points (about one per two exterior doors), each floor, and the garage. A large house typically needs several cameras to watch entrances, the perimeter, and key interior zones — the tool gives a sensible starting count you can refine on site.
What sensors should I include?
The planner suggests a door sensor on every exterior door, a window sensor on each ground-floor window (the most common break-in points), and motion sensors scaled to the number of floors. Together these create layered coverage so the system detects both entry attempts and movement inside.
Will my real security cost match this estimate?
These are estimates only; verify with professionals. The figure covers typical hardware and a hub but not wiring, monitoring subscriptions, or professional installation — a security pro should survey the property for blind spots and any code requirements.
