IP Camera vs Analogue Camera — Which is Right for Your Business?

How Each Technology Works

An analogue camera captures video and sends it as a continuous electrical signal over a coaxial cable to a DVR (Digital Video Recorder), which converts and stores the footage. The processing happens at the DVR — not the camera.

An IP camera (Internet Protocol camera) digitises and compresses the video inside the camera itself, then transmits it as data packets over a CAT5e/CAT6 network cable (or Wi-Fi) to an NVR (Network Video Recorder) or directly to cloud storage. Because the camera handles its own processing, each unit is effectively a small computer on your network.

Image Quality

This is where IP cameras win decisively. Analogue cameras are limited to resolutions of 720p or 1080p (with HD-CVI/AHD/TVI variants). IP cameras are available in 2MP (1080p), 4MP, 5MP, 8MP (4K) and even higher — delivering significantly more detail, wider field of view and better digital zoom without losing clarity. For licence plate reading, facial identification or large open areas, IP cameras are the clear choice.

Cabling and Infrastructure

Analogue systems use RG59 coaxial cable — thicker, less flexible, and running one cable per camera back to the DVR. If you already have coaxial cabling in your building, analogue can be a cost-effective upgrade path using HD-CVI or AHD cameras on existing cables.

IP systems use standard CAT5e or CAT6 network cable with PoE (Power over Ethernet) switches — one cable carries both power and data. This simplifies installation, supports longer cable runs (up to 100m standard, further with extenders) and shares infrastructure with your IT network.

Cost Comparison

Analogue cameras and DVRs are generally cheaper upfront — a basic 8-channel analogue system costs less than its IP equivalent. However, IP systems offer better long-term value: lower installation labour (one cable per camera), higher resolution without extra cost at scale, and no need to replace cabling if you upgrade cameras later. For new installations with no existing coaxial cable, IP is usually comparable or better value at total project cost.

Scalability and Remote Access

IP systems are far more scalable. Adding cameras simply means connecting to your network switch — no need to run additional cables back to a central point. Multi-site viewing, cloud storage and remote access via mobile apps are native to IP systems. Analogue systems require additional hardware (network bridges or hybrid DVRs) to achieve the same remote access capabilities.

Which Should You Choose?

• Choose Analogue/HD-CVI if you have existing coaxial cabling you want to reuse, or if you have a very small site with a tight budget and no plans to expand.
• Choose IP for all new installations, larger sites, high-security areas requiring better image quality, multi-site deployments, or anywhere you want cloud or remote access built in from day one.

For most businesses installing or upgrading a CCTV system today, IP cameras are the recommended choice — the technology is mature, costs have come down significantly, and the long-term flexibility is far superior.
