How Many Security Cameras Does Your Property Need?
Cover entry points first, then valuables. Typical camera counts for homes, shops and farms, plus a simple scoring method.
What matters in practice:
- Entry points first, then valuables — a camera on the gate everyone uses beats five on empty walls.
- Score each spot 1 to 3 for likelihood and 1 to 3 for loss, then multiply — cover the highest numbers first.
- Each extra camera costs power, WiFi, storage and alerts — buy for the gaps you can name, not the box that was on sale.
Too few cameras and you leave blind spots. Too many and you pay for cameras that watch nothing useful, and bury yourself in alerts. Here is a practical way to get the number right.
The short answer
Cover the entry points first, then the places that hold your valuables, then add more only where you see a real gap.
Start with a walk-round
Walk your property the way a thief would. Note every door, gate, window and route in, and every spot where something valuable sits. Mark them on a sketch. Then note where the power and WiFi are.
Typical starting numbers
| Property | Starting cameras | Where |
|---|---|---|
| Small home | 2 to 3 | Front door, back door, driveway |
| Larger home with compound | 4 to 6 | Add side access, gate, compound corners |
| Small shop | 3 to 4 | Entrance, till, stock room, back door |
| Larger shop or small warehouse | 6 to 10 | Add aisles, loading area, outside |
| Farm yard and buildings | 4 to 8 | Gate, fuel store, machinery shed, workshop, animal housing |
These are starting points. Your layout decides the final number.
Rules that help
- One camera per entry point
- Every camera should cover another camera's blind spot where possible
- Cover the cameras themselves, so tampering is seen
- Prioritise by value. Cash, stock, tools and fuel come before empty corners
- Choose the resolution per spot, rather than the same for all
- Add cameras later, once you see what you actually need
A simple scoring method
For each spot on your sketch, give it a score from 1 to 3 for how likely someone is to go there, and 1 to 3 for how costly a loss would be. Multiply them. Cover the highest scores first.
Don't forget the practical costs
| Each extra camera adds | Consider |
|---|---|
| Power point or solar panel | Do you have power there? |
| WiFi load | Will the router cope? |
| Storage | More footage to hold |
| Alerts | More notifications to manage |
| Maintenance | More lenses to clean |
Fewer, better-placed cameras beat many badly placed ones
A camera aimed well at the one gate everyone uses is worth more than five cameras pointing at empty walls.
Common mistakes
- Buying a big kit and then finding half the cameras have no good position
- Pointing cameras at the sky or the ground
- Forgetting the back and the sides of the property
- Spending on cameras and nothing on lighting
Frequently asked questions
Do I need cameras inside as well? Only where you want to monitor, such as a shop floor or a store. Respect privacy at home.
Should I start with a kit? A kit with spare channels is a good start for three or more cameras.
Can I add cameras later? Usually yes, if your recorder or app supports more.
