When you plan a CCTV system, one of the first choices is the type of camera: IP or analogue. They look similar on a wall, but they work differently, need different cables and recorders, and suit different situations. This guide explains the difference in plain language so you can choose with confidence.
What is an analogue (HD) camera?
An analogue camera sends its video along a coaxial cable to a DVR or XVR recorder, which converts the signal to digital and saves it. Modern analogue HD systems (often called HDCVI, AHD, or TVI) give much sharper pictures than the old standard-definition cameras. They need a separate power supply or a combined power-and-video cable.
What is an IP camera?
An IP camera is a small computer that processes its own video and sends it digitally over a network cable to an NVR recorder. Many IP cameras use PoE (Power over Ethernet), so one cable carries both power and video. Read PoE for CCTV explained.
IP vs analogue: the key differences
| IP camera | Analogue HD camera | |
|---|---|---|
| Recorder | NVR | DVR or XVR |
| Cable | Network cable (Cat5e/Cat6), often with PoE | Coaxial cable plus power |
| Resolution | Wide range, up to 4K and beyond | Up to 4K on newer models |
| Smart features | Usually more, such as person and vehicle detection | Fewer, depending on the recorder |
| Cable length | Up to 100 m per run, longer with switches | Often suits longer simple runs |
| Starting cost | Can be higher | Can be lower, especially when reusing coax |
| Expansion | Easy: add cameras through a network switch | Limited by recorder channels |
When to choose IP cameras
- You are building a new system and can run network cable
- You want smart features that reduce false alerts
- You may add cameras later or need cameras across several buildings
- You want one cable for power and video with PoE
When analogue HD still makes sense
- You are upgrading an older building that already has coaxial cable in place
- You want the lowest starting cost for a basic system
- You have long, simple cable runs that are easy to reuse
A hybrid XVR recorder can handle analogue HD cameras and a limited number of IP cameras, so you can keep existing cameras and add new ones gradually.
What about image quality?
Both types can give good pictures. What you actually see depends on resolution, the lens, the sensor, night vision, and placement, not only on IP versus analogue. Read CCTV resolution explained and how to plan placement.
Which one do most people need?
For most new homes, shops, and offices, wired IP cameras with an NVR are the better long-term choice, because of the flexibility, features, and simple PoE cabling. Analogue HD is a sensible option when you are reusing existing cable. If you are unsure, a site survey will show what is already in place. See NVR vs DVR for the recorder side.
What affects the cost of each type
The camera itself is only part of the price. For an analogue system, you pay for the cameras, a DVR or XVR, coaxial cable, and power supplies, and you save money if good coaxial cable is already in the walls. For an IP system, you pay for the cameras, an NVR, network cable, and a PoE switch if the recorder does not have enough PoE ports, but one cable per camera keeps the installation simple. Storage, installation, and the number of cameras usually matter more to the final price than the camera type. Our CCTV price guide explains the full picture.
Questions to ask before you decide
- Is there already coaxial or network cable in the building that can be reused?
- How many cameras do I need now, and might I add more later?
- Do I want smart features, such as person and vehicle detection?
- How long are the cable runs from the recorder to each camera?
- Do I need cameras in more than one building?
Frequently asked questions
Can I use IP cameras with my old DVR?
Standard DVRs only support analogue cameras. A hybrid XVR can accept some IP cameras. For a mostly-IP system, use an NVR.
Are IP cameras always better?
They are more flexible and often have more features, but analogue HD can be a good, lower-cost fit where coaxial cable is already installed.
Do IP cameras need internet?
No. An IP camera system records to its NVR without internet. You need internet only to watch remotely. Read does CCTV work without internet?
