Which CCTV camera is best for home?

For most homes, 2 MP (1080p) dome cameras indoors and bullet cameras outside give clear coverage. Choose 4–5 MP for gates and parking where you want to identify faces or number plates, and colour night vision for more useful footage at night.

Is DVR or NVR better?

A DVR with HD analogue cameras is economical for small homes and shops. An NVR with IP cameras gives sharper video, uses one cable for power and data (PoE) and is easier to expand — better for offices and larger houses.

CCTV buying guide: choosing cameras for your home or shop

Dome or bullet, DVR or NVR, 2 MP or 5 MP, and how much storage you really need — a plain-language guide before you buy.

A good CCTV system is less about the most expensive camera and more about the right camera in the right place. Here's what to decide before you buy.

1. Where do you need coverage?

Walk around the premises and list the entry points — main gate, front door, back door, parking, cash counter. Most homes need 2–4 cameras; most shops need 4–8.

2. Dome or bullet?

Dome cameras are compact and discreet — ideal indoors and under porches.
Bullet cameras are visible, deter intruders and usually see further — ideal for gates, parking and outdoor walls.

3. HD analogue (DVR) or IP (NVR)?

HD analogue systems cost less and suit homes and small shops. IP systems give sharper video, use a single network cable for power and data, and are easier to expand later.

4. Resolution

2 MP (1080p) is enough for general monitoring. Choose 4–5 MP where you need to read number plates or identify faces from a distance.

5. Night vision

Check the IR range printed on the camera. For dark areas, colour night-vision cameras give much more useful footage than black-and-white IR.

6. Storage

Four 2 MP cameras recording continuously fill roughly 1 TB in 10–15 days. Use a surveillance-grade hard disk, and put the recorder on a UPS.

7. Installation matters

Camera height, angle, cable quality and weather-proof connectors decide whether you get usable footage. A site survey before installation avoids blind spots and rework.
