IP vs HDCVI: Choosing the Right Surveillance Technology for Your Project
Both carry high-definition video. The right choice depends on your existing cabling, the size of the site and how the system needs to grow.

Choosing between network (IP) and HDCVI cameras is one of the first decisions in any surveillance project. Both can deliver high-definition video. The difference is in how the signal travels, how the system is powered and how it scales.
How each technology works
HDCVI sends high-definition video over coaxial cable to a recorder, usually called an XVR. Each camera has its own cable run back to the recorder.
Network (IP) cameras send video over standard Ethernet. Cameras connect to network switches — often with power-over-Ethernet (PoE) — and the video is recorded on a network video recorder (NVR) or a central platform.
When HDCVI makes sense
- The building already has good coaxial cabling you want to reuse
- The site is small to medium with cameras close to the recorder
- You want a straightforward upgrade from older analog cameras
When IP makes sense
- New buildings or new cabling
- Larger or multi-building sites that need to grow over time
- Projects that need analytics, central management or integration with access control
- Sites where one network cable for power and video simplifies installation
Questions to answer before you choose
- What cabling already exists, and what condition is it in?
- How many cameras do you need now, and in three years?
- How long must footage be kept?
- Who needs to view video, and from where?
- Will the system connect to access control, alarms or a control room?
