HD vs IP Cameras
Which CCTV technology is right for your property?
Understanding the differences between HD-over-coax and IP camera systems will help you make the right choice for your CCTV infrastructure and long-term security investment. Here’s what you need to know before upgrading or deploying a new surveillance system.
HD-over-Coax
Also known as: HDCVI, HDTVI, AHD
HD-over-coax sends high-definition video over traditional coaxial cabling used in older CCTV systems.
Best For:
- Upgrading existing analogue systems
- Long cable runs (300m+)
- Budget-conscious installations
IP Cameras
RecommendedNetwork-based surveillance
IP cameras transmit video over Ethernet networks, enabling higher resolutions, AI analytics, with modern IT infrastructure.
Best For:
- New installations and fit-outs
- AI-powered intrusion detection
- Enterprise and multi-site deployments

Our Recommendation
Choose HD-over-Coax if:
- You have existing coaxial cabling in good condition
- Cable runs exceed 100 metres
- Budget is the primary concern
- You don’t need advanced AI analytics
Choose IP Cameras if:
- You’re installing a new system or building
- You want AI-powered intrusion detection
- Future scalability is important
- You need enterprise-grade features
