Analogue vs IP-Based CCTV
When planning a new CCTV installation or upgrading an existing system, one of the first decisions to make is whether to choose an analogue or IP-based CCTV system. Both provide effective surveillance but differ in image quality, scalability, and cost.
Understanding these differences helps you make an informed choice for your home or business.
What Is an Analogue CCTV System?
Analogue CCTV systems have long been the traditional choice for security installations across the UK. They transmit video signals over coaxial cables to a Digital Video Recorder (DVR).
Key Advantages
- ✅ Reliable wired connection – consistent performance without internet reliance.
- ✅ Cost-effective setup – lower equipment and installation costs.
- ✅ Simple to operate – straightforward playback and maintenance.
Limitations
- ⚠️ Lower resolution than IP cameras.
- ⚠️ Fewer smart features such as motion analytics or cloud access.
- ⚠️ Weaker performance in low-light conditions.
Analogue systems remain reliable and affordable for basic surveillance needs.
What Is an IP-Based CCTV System?
IP (Internet Protocol) systems transmit digital video signals over a local network or the internet to a Network Video Recorder (NVR) or the cloud
Key Advantages
- 🚀 High-definition clarity up to 4K resolution.
- 🧠 Smart features like motion detection, facial recognition, and alerts.
- 🌍 Remote viewing via smartphone or computer.
- 💡 Excellent colour night vision using ColorVu or Starlight.
- 🔒 Flexible storage options – NVR, SD card, or cloud.
Considerations
- ⚠️ Dependent on network quality.
- ⚠️ Slightly higher upfront cost, but future-ready and scalable

| Installation Cost | Lower | Higher but scalable |
| Remote Access | Limited | Full mobile/cloud access |
| Best For | Homes, small sites | Commercial & advanced setups |
Which CCTV System Is Right for You?
Your decision depends on budget, property type, and performance needs:
- Analogue CCTV – reliable and affordable, great for smaller installations.
- IP CCTV – advanced, flexible, and ideal for businesses or large properties.
Modern IP systems are becoming the preferred choice due to their high image quality and smart analytics

Frequently Asked Questions
Analogue CCTV uses coaxial cables to transmit video signals to a DVR, while IP CCTV uses a digital network to send footage to an NVR or cloud storage. IP cameras generally offer higher resolution, better features, and remote viewing capabilities.
Yes. You can usually upgrade your analogue system to IP using your existing cabling and hybrid DVR/NVR recorders. This lets you replace cameras gradually without starting from scratch.
IP CCTV systems offer superior image quality (up to 4K), smart analytics, and remote access. Analogue CCTV systems, however, are reliable and more affordable for smaller sites or basic setups.
No. IP cameras can record locally to an NVR without an internet connection. The internet is only required for remote access or cloud backup.
Yes, when properly installed. Using strong passwords, encryption, and regular firmware updates helps keep IP CCTV systems secure from unauthorised access.
Yes. Hybrid recorders allow you to connect both analogue and IP cameras on one system, ideal for gradual upgrades or mixed installations.
IP CCTV provides sharper images, flexible installation, advanced motion detection, and remote monitoring — making it ideal for both homes and commercial sites.
Yes. Many businesses and homeowners still use analogue CCTV effectively. However, most new installations now favour IP systems due to the benefits of higher quality and remote access.
While analogue CCTV is still supported and available, IP CCTV has become the preferred standard for new systems thanks to improved technology and smarter functionality.
Costs vary depending on camera resolution, storage type, and installation requirements. Typically, upgrading from analogue to IP starts around £600–£1,200 for a small 4-camera system with professional installation.
No licence is needed for private CCTV use, but if your cameras cover public areas, you must comply with UK GDPR and ICO guidelines regarding data privacy and signage.
