Centralize surveillance video from up to 32 IP camera channels in a dedicated 4K network video recorder. The UNITED DIGITAL NVR504-32B provides the recorder layer between an IP camera network and the operators responsible for viewing, searching, and retaining site video. Its 32-channel capacity suits deployments that exceed the scale of a small camera installation while keeping recording under one appliance. Use the recorder as the video-management endpoint for cameras connected through the surveillance network. A 4K recording capability supports deployments where image detail matters for identification, incident review, and monitoring across wide scenes. Camera channel capacity is a primary sizing consideration: account for every camera expected to record to the appliance, including cameras planned for future installation within the same recorder domain. NVR504-32B is specified as a 32-channel 4K NVR, making channel count and recording resolution the defining selection points for this configuration. Integrators can pair the recorder with storage, cameras, networking, and display equipment appropriate to the retention period and surveillance workflow required at the site. Confirm camera interoperability, storage sizing, recording schedules, and network bandwidth as part of the system design before installation.
