Most 2K IP cameras use Power over Ethernet (PoE), carrying power and network data over one Ethernet cable connected to a compatible PoE switch, injector, or network video recorder (NVR). They can send video to an NVR or compatible surveillance platform for recording, while some models also support local microSD storage and remote viewing through a camera app.

Dome 2K IP cameras use a low-profile, discreet housing for ceiling or surface mounting, while turret cameras offer a compact design suited to indoor or exposed outdoor installations. Bullet cameras provide a more visible, directional form factor with adjustable mounting, and flexible 2K IP cameras support table or ceiling placement for adaptable indoor setups, with some configurations supporting outdoor use with an appropriate mount.

Many 2K IP cameras use infrared (IR) night vision to illuminate scenes in low-light or no-light conditions, while low-light image sensors and processing help preserve visible detail. True wide dynamic range (WDR) or high dynamic range (HDR) helps balance bright and shadowed areas in high-contrast scenes.

2K IP cameras can connect to compatible network video recorders and monitoring platforms over Ethernet, with Power over Ethernet (PoE) carrying video, data, and power through one cable on supported systems. For smart home integration, select cameras and platforms that support ONVIF or a compatible app and control-system connection for live viewing, recordings, notifications, and camera management.
