If you are not sure which CCTV system is right for you, this guide will help explain the differences between camera systems in simple terms.
Whether you need CCTV for your home, shop, warehouse, restaurant, or office, choosing the correct system depends on your budget, the image quality you need, and the size of the property.
Analogue HD vs IP CCTV Systems
There are two main types of CCTV systems available today:
1. Analogue HD CCTV Systems
Analogue HD cameras use traditional BNC coaxial cables (similar to old TV aerial cables). They can also use CAT5 or CAT6 network cable with video baluns.
Advantages
Lower cost
Easy to install
Very reliable
Excellent for homes and small businesses
Typical Camera Prices
2MP to 5MP cameras: around £20–£40
8MP 4K cameras: around £60–£70
Best For
Homes
Small shops
Restaurants
Customers on a budget
2. IP CCTV Systems
IP cameras use CAT5 or CAT6 network cables, similar to internet or router connections.
IP cameras contain more advanced electronics and work like mini computers, which is why they cost more.
Advantages
Better image quality
Sharper digital zoom
Easier to identify faces and number plates
Better for large buildings and long cable runs
Typical Camera Prices
Entry-level IP cameras: around £40–£50
Advanced models: £200–£300+
Best For
Warehouses
Large businesses
Customers needing high-detail images
Long-distance cable runs
👉 CCTV Resolution Explained
Modern CCTV cameras are available in different resolutions:
2MP – Basic HD
5MP – Very popular for homes and shops
6MP / 3K – Improved clarity
8MP / 4K – Highest detail and best digital zoom
The higher the resolution, the clearer the image will be — especially when digitally zooming in to identify faces or read vehicle number plates.
Both Analogue HD and IP systems are available up to 8MP 4K resolution, but IP systems usually provide better image definition when zooming in.
❓DVR vs NVR – What’s the Difference?
DVR (Digital Video Recorder)= used with Analogue HD systems
NVR (Network Video Recorder)= used with IP systems
The prices of DVRs and NVRs are generally similar.
👇Things to Consider Before Buying CCTV
Before choosing a CCTV system, consider the following:
Your budget
Home or business use
Indoor or outdoor installation
Required image quality
Distance you need to see clearly
Preferred brand or generic/OEM equipment
👇Best CCTV Systems for Different Situations
👉 CCTV for Homes
Mid-Terraced Houses
Usually 2 cameras are enough:
Front
Rear garden
5MP or 6MP Analogue HD systems are normally sufficient.
End-Terraced Houses
Usually 2–3 cameras:
Front
Rear
Side access if applicable
Semi-Detached Houses
Usually 3–4 cameras:
Front
Side drive
Rear garden
If extensions create blind spots, additional cameras may be required.
Detached Houses
Usually 4–6 cameras depending on:
Side entrances
Windows
Garden coverage
Garages and driveways
👉 CCTV for Shops and Small Businesses
Turret dome cameras are the most popular choice because they are:
Neat looking
Waterproof
Suitable for indoor and outdoor use
Often supplied with built-in audio
Recommended Setup
One camera over the till
One camera per aisle
Additional cameras for blind spots
For best identification, 5MP, 6MP (3K), or 8MP cameras are recommended.
👉 CCTV for Warehouses and Larger Buildings
IP systems are usually recommended because:
Cable runs can be much longer
Image quality remains high
Better for higher ceilings
Easier to expand later
2.8mm wide-angle cameras are commonly used and provide approximately 90° coverage.
Remember: Cameras only see in one direction and cannot see around corners. Always check for blind spots when planning camera positions.
👉 Turret vs Bullet Cameras
👉 Turret Cameras
Most popular option for homes and businesses.
Advantages
Better night vision performance
More discreet appearance
Less reflection from infrared LEDs
Excellent for indoor and outdoor use
👉 Bullet Cameras
Bullet cameras provide the same image quality as turret cameras but have a longer visible shape.
Some customers prefer them as a visual deterrent.
👇 PTZ Cameras Explained
PTZ stands for:
Pan
Tilt
Zoom
PTZ cameras can move and zoom remotely.
They are ideal when:
A security guard is monitoring live footage
Large outdoor areas need active monitoring
Auto-tracking PTZ cameras can automatically follow movement, but not all PTZ models include this feature.
❓Which CCTV Brand Is Best?
Some of the most popular CCTV brands in the UK are:
Hikvision
Dahua
HiLook
Uniview
Hikvision & Dahua
The two best-known brands with excellent reliability and image quality.
HiLook
A more budget-friendly option made by Hikvision.
Uniview
Very good quality and often slightly cheaper.
OEM / Generic CCTV Systems
Many OEM systems are manufactured to the same specifications as branded systems and can offer excellent value for money.
Some Hikvision OEM products are fully compatible with Hikvision equipment but come with shorter warranties.
❓ Can You Install CCTV Yourself?

You should be comfortable with:
Using ladders
Drilling holes
Running cables
