Centralize recording for up to eight IP cameras with 4K video support and eight integrated Power over Ethernet ports. The UNITED DIGITAL NVR502-08B-P8 combines network video recording and camera power delivery in one appliance, allowing supported PoE cameras to connect directly to the recorder rather than requiring separate PoE switching for every camera connection. An eight-channel design fits focused surveillance deployments such as small offices, retail locations, entrances, equipment rooms, and perimeter camera groups. Each built-in PoE port provides a direct connection path for a camera, helping keep camera network and power cabling concentrated at the recording location. The recorder handles the core NVR functions required for camera recording and video review while supporting 4K-resolution recording. This model pairs its eight-camera capacity with an equal count of integrated PoE ports. That one-to-one port arrangement is the defining configuration for installations where every connected camera is intended to receive power from the NVR. Select it when the system calls for an 8-channel 4K recorder with local PoE camera connections, rather than a recorder that depends entirely on an external PoE switch.
