Six questions, honest math. You'll get a camera count with a per-area breakdown — not a sales pitch. Then map the exact spots with the free placement tool.
Your property
Your coverage plan
Answer the questions and tap "Count my cameras" — the per-area breakdown appears here.
Every door people actually use gets a face-height view. That's non-negotiable — it's where evidence comes from.
Vehicles second
Driveways and lots need two angles: context (what happened) and a tighter view toward the entrance (who/plate).
Then the money spots
Registers, front desks, stockrooms, safes — wherever value changes hands or disputes happen.
Answers
Camera count questions
How many cameras for an average home?
Usually 4–6: front door, back/side door, driveway or garage, plus an overview. Detached garages, alleys and bigger lots push 6–8.
How many for a small business?
Typically 6–10: public entrance, employee door, register/desk, stock, parking and an interior overview. Warehouses and restaurants trend higher.
More cameras or better cameras?
Coverage first — every entrance and key area gets a view. Then quality where it counts: 40+ PPF at doors and choke points. Check yours with the PPF calculator.

How to use the how many security cameras do I need
The number of security cameras you need depends on distinct views, not square footage alone. Count entrances, vehicle approaches, exterior sides, transaction or inventory areas and critical interior paths, then separate wide situational views from close identification views. This calculator converts those zones into a practical starting quantity.
Use it in three steps
Count every entrance, driveway, parking zone and exterior side that needs a separate useful view.
Add interior choke points or high-value areas only where cameras are appropriate and lawful.
Review the suggested count against the visual placement tool so one camera is not expected to do two incompatible jobs.
Know the limit
The result is an estimate. Walls, corners, lens choice, mounting height, lighting, privacy rules and the required identification detail can increase or decrease the final camera count.
Questions people ask
How many security cameras does a typical property need?
There is no universal number; count the independent views needed for entrances, approaches, exterior sides and critical interior areas.
Can one wide-angle camera cover two doors?
Sometimes, but a wide overview may not capture enough facial detail at either door. Identification and overview are different camera jobs.
Should I buy cameras before planning locations?
Plan views, lighting, cable routes and recorder capacity first so the equipment matches the property instead of forcing the layout around a camera kit.
