Home security buyers often start by counting cameras, but coverage and placement matter more than the number on the box. A smaller, well-planned system can protect key entrances better than a larger poorly positioned one.
Key takeaways
- Choose cameras around the entrances, blind spots, and lighting conditions you actually have.
- Night vision quality and recorder storage are as important as camera resolution.
- Remote viewing needs stable internet and correct setup, not just a camera with an app.
Which camera type fits a home?
Bullet cameras are useful for visible outdoor coverage, while dome cameras are often tidier under eaves or inside entrances. The best option depends on weather exposure, viewing angle, and how easy the camera is to reach.
For a typical home, start with the gate, front door, driveway, and any rear access point. Add more only where there is a genuine blind spot.
- Outdoor weather protection
- Wide-angle coverage
- Night vision range
- Power and cable route
Storage and phone viewing
A camera system is only useful if footage can be reviewed when something happens. Recorder capacity determines how many days are retained, while internet quality affects whether remote phone viewing works smoothly.
Ask how the system behaves during an internet outage and whether footage continues recording locally. That distinction matters for homes with unreliable connectivity.
Questions to ask before installation
Request a clear package that separates hardware, cabling, labour, setup, and any remote-viewing configuration. This makes quotes easier to compare and avoids surprises after installation.
Frequently asked questions
How many CCTV cameras does a house need?
There is no fixed number. Start with entrances, driveways, and blind spots, then add coverage based on the property layout.
Do home CCTV cameras work without internet?
Most recorder-based systems can keep recording locally without internet, but remote phone viewing will not work until connectivity returns.
Is 4MP or 5MP CCTV better for a home?
Higher resolution can improve detail, but placement, lighting, lens choice, and storage capacity also affect the result.
