Ethernet surveillance cameras connect to an active Power over Ethernet (PoE) port on a compatible PoE switch or network video recorder through a single Ethernet cable that carries both power and video data. The switch or recorder then connects to the existing network, allowing authorized users to view camera feeds through compatible software or apps while the NVR manages recording.

Compare 4MP and 8MP options based on the detail your scene requires, then choose a fixed 2.8 mm lens for a consistent view or a motorized 2.7–13.5 mm varifocal lens when installers need adjustable framing. For nighttime coverage, compare infrared ranges up to 25, 30, or 60 meters, or consider color-at-night cameras with low-light imaging and supplemental warm-white LEDs for color video in dark scenes.

Many ethernet surveillance cameras can record locally to a microSD card, so a network video recorder is not always required. Local storage can support standalone viewing and recording through a compatible app, while an NVR can provide centralized storage and management for a larger multi-camera system.

Ethernet surveillance cameras can connect to a compatible network video recorder or video management platform through Ethernet and, when supported, use ONVIF for integration with compatible devices. Many models also support Power over Ethernet (PoE), local microSD recording, mobile app viewing, and smart home control platforms for live video, playback, and camera management.
