Centralize IP camera recording, live viewing, and stored-video access for systems with up to 64 camera channels. The UNITED DIGITAL NVR502-16B-P16-IQ is an AI network video recorder with 16 built-in PoE ports, allowing directly connected compatible cameras to receive network connectivity and power from the recorder. This layout reduces the number of separate network connections required at the recorder for installations using up to 16 directly attached PoE cameras. Sixteen HDD bays provide substantial capacity for locally retained surveillance video. The recorder suits sites that need to retain footage from a larger camera estate without limiting storage to a small fixed drive count. Camera channels beyond the built-in PoE port count can connect through the surveillance network, making the platform applicable where cameras are distributed across existing network switching as well as where a group of cameras terminates directly at the recorder. AI NVR classification distinguishes this configuration from a conventional recorder focused only on video transport and storage. It provides an AI-capable recording platform for deployments that require video analytics as part of their surveillance workflow, while retaining the channel density, PoE connectivity, and HDD-bay count needed for larger installations. Select it where 64-channel management, 16 direct PoE connections, and 16-bay local storage are required together.
