Analogue vs IP Cameras: What's the Difference?
Share
IP cameras send digital video over a network cable (or PoE) to an NVR, giving higher resolution and smart features. Analogue cameras send video over coax to a DVR - cheaper and simpler, and great for reusing existing cable. For most new installs, IP is the better long-term choice.
IP cameras + NVR
Each IP camera is effectively a small networked device with its own digital feed. Connected to an NVR by PoE, you get a single cable for power and data, higher resolutions (up to 8MP/4K and beyond), and smart analytics like person/vehicle detection. This is what most modern kits use.
Analogue cameras + DVR
Analogue cameras (modern ones use Turbo HD / HDTVI) send their picture over coax cable to a DVR. They're typically cheaper and very simple, and now reach up to 8MP. The catch is fewer smart features and separate power runs - but they're ideal if you already have coax in the walls.
At a glance
| IP | Analogue | |
|---|---|---|
| Cabling | Network / PoE (1 cable) | Coax (+ power) |
| Recorder | NVR | DVR |
| Resolution | Up to 8MP+ | Up to 8MP |
| Smart features | More (AcuSense etc.) | Fewer |
| Cost | Higher | Lower |
| Best for | New installs, smart features | Reusing coax, simple/budget |
Reusing existing cable
If your property already has coax from an old system, analogue (or HDTVI) lets you upgrade the cameras and recorder without rewiring - often the deciding factor.

Frequently asked questions
Is IP better than analogue?
For new installs IP usually wins - higher resolution, single-cable PoE and smart detection. Analogue is cheaper and ideal if you're reusing existing coax cable.
Can I reuse my old coax cable?
Yes - modern analogue (Turbo HD / HDTVI) cameras and DVRs run over existing coax, so you can upgrade an old system without rewiring.
Do analogue cameras do 4K?
Modern analogue (Turbo HD) cameras now reach up to 8MP/4K over coax, though IP still leads on smart features and flexibility.
