Centralize recording for up to 16 IP cameras with 4K recording capability and integrated Power over Ethernet connections. This network video recorder combines camera connectivity, video recording and local surveillance management in one appliance for sites that need a dedicated on-premises recording point. Its 16 built-in PoE ports can connect compatible cameras directly, providing both network access and power from the recorder. The UNITED DIGITAL NVR502-16B-P16 fits medium-size camera systems where a separate PoE switch would otherwise be required at the recorder location. It supports 16 camera channels, allowing coverage across entrances, corridors, loading areas, offices and other monitored zones while keeping recording traffic concentrated at the NVR. 4K capability supports deployments using higher-resolution IP cameras where scene detail is important for review. Integrated 16-port PoE is the defining connection capability of this configuration. Each compatible camera can home-run to the recorder rather than terminate at a separate power source or switching layer. Use it where the camera count aligns with the recorder's 16-channel capacity and a centralized PoE-connected NVR is preferred for installation and ongoing camera management.
