DVR vs NVR: which is right for your premises?
The practical differences that actually affect your footage.
When you buy a CCTV system, the recorder is just as important as the cameras. It's where your footage is stored, managed and viewed — and the two main types, DVR and NVR, work quite differently.
Choosing the wrong one can leave you with poor image quality, limited expansion or higher costs down the line. Here's how they compare in plain terms.
What is a DVR?
A DVR (Digital Video Recorder) works with analogue cameras connected over coaxial cabling. The camera sends a raw video signal to the DVR, which processes and records it.
- Works with analogue cameras
- Uses coaxial cabling
- Lower initial cost
- Best for small, simple setups
What is an NVR?
An NVR (Network Video Recorder) works with IP cameras over your network. Each camera processes its own video and sends it to the NVR digitally, often over a single Ethernet cable that also supplies power (PoE).
- Works with IP cameras
- Uses Ethernet (LAN) cabling, PoE optional
- Higher image quality, up to 4K and beyond
- Easy to scale and expand
The key differences
Image quality
DVR systems typically top out around 1080p (2MP). NVR systems support much higher resolutions — 4MP, 5MP and 4K — which matters when you need to identify faces or vehicle number plates.
Cabling and installation
DVRs need coaxial cable plus separate power, which means more wiring. NVRs use a single Ethernet cable per camera with PoE, making installation cleaner and more flexible — especially across multiple floors.
Scalability
Adding cameras to a DVR is limited by physical ports and cabling. NVR systems are far easier to expand as your needs grow.
Features
NVRs generally offer more advanced analytics, smart motion alerts, better remote access and easier integration with other systems.
Choose a DVR if…
- You're on a tight budget
- You already have coaxial cabling in place
- You need a simple system for a small area
Choose an NVR if…
- You want high-quality, high-resolution video
- You need advanced features and reliable remote access
- You plan to grow or add more cameras over time
Our advice
For most modern businesses and growing premises, NVR systems offer better performance, flexibility and long-term value. DVRs still make sense for small, budget-focused installs or where good coaxial cabling already exists.

We'll assess your premises, cameras and budget, then recommend and install the right recorder and system for your needs — whether that's a simple DVR setup or a scalable NVR solution.
Frequently asked questions
Not directly — NVRs are designed for IP cameras. You can bridge analogue cameras using encoders, but if you're upgrading it's often better to move to IP cameras to get the full benefit.
Not always. NVRs offer higher quality and easier expansion, but a DVR can be the smarter choice for a small, budget-conscious setup or where coaxial cabling already exists.
Both support remote viewing, but NVR systems generally offer smoother apps, higher-quality streams and more advanced alerts.
Yes. We survey your premises and recommend the recorder, cameras and storage that best fit your security needs and budget.
