Cable – Ethernet
Like DVR systems, NVR systems connect the camera to the recorder. However, how they connect the camera to the recorder is entirely different. NVR systems use standard Ethernet cables, such as cat5e and cat6, to transmit data. Professional installers prefer ethernet cables due to the number of advantages compared to coaxial cables:
Ethernet cable powers the camera using Power over Ethernet (PoE), which means your camera needs one cable running to capture video, audio, and power the camera, thus eliminating the need for messy splitters like a DVR system.
Ethernet cable tends to be easier to route and terminate because it is thinner and has a smaller connector allowing for less drilling.
Ethernet is cheaper than coaxial cable and much more readily available, making cable replacement or system expansion more accessible and affordable. Many modern homes and businesses are being built wired for Ethernet, making installation even easier.
An added advantage of Ethernet cable is that every camera on the system can transmit audio since Ethernet can send audio data natively.
Cables do not need to run between every camera and the recorder. They need to be on the same wireless network. Installation is more straightforward and cleaner as multiple cables aren’t required.
Despite a shorter max Ethernet cable length, 328ft or 100m, network switches can be used to extend total distance without impacting image quality.
