Standard Non-PoE Recorder
The NVR504-32B does not include built-in PoE camera ports. IP cameras must connect through a compatible external PoE switch or network infrastructure.
This is the standard NVR504-32B model and should not be confused with the NVR504-32B-IQ or NVR504-32B-P16-IQ models.
Enterprise-Grade Recording

Connect and manage up to 32 compatible IP cameras for centralized live viewing, recording, playback, event review, and system administration.
Up to 16MP Recording
Supports high-resolution recording from compatible cameras at resolutions up to 16 megapixels for detailed evidentiary video.
High Network Bandwidth
Provides up to 320Mbps incoming and 160Mbps outgoing bandwidth for demanding multi-camera surveillance installations.
Four SATA Hard-Drive Bays
Accommodates up to four compatible surveillance hard drives, allowing storage capacity to be configured around recording duration, camera count, resolution, and frame rate.
RAID 1 and RAID 5 Support
Supports RAID storage configurations and redundant recording options to help improve storage resilience in professional surveillance environments.
Independent HDMI and VGA Outputs
Provides HDMI output up to 4K resolution along with independent VGA output for flexible local monitor configurations.
Ultra 265 Video Compression
Supports Ultra 265, H.265, and H.264 video formats to help reduce storage and network-bandwidth requirements when used with compatible cameras.
Automatic Network Replenishment
ANR technology can retrieve supported edge recordings from compatible cameras after a temporary network interruption, helping improve recording continuity.

Camera-Side Intelligence
Compatible Smart Event Integration
When paired with compatible intelligent IP cameras, the NVR504-32B can receive, display, record, and search supported camera-generated analytics and VCA events.
Supported functions may include face detection, vehicle detection, license-plate recognition, intrusion detection, cross-line detection, Ultra Motion Detection, temperature events, people counting, video metadata, heat maps, and traffic-monitoring events.
This standard recorder does not add IQ-series recorder-side analytics to ordinary cameras. Smart functions depend on the connected camera, firmware, feature licensing, system resources, and configuration.

Third-Party Camera Integration
Third-party IP cameras may not be plug-and-play and may require manual network, ONVIF, RTSP, user-account, stream, codec, resolution, and frame rate configuration.
Compatibility may vary depending on the camera’s ONVIF profile, firmware version, authentication method, video codec, resolution, frame rate, audio format, stream profile, and supported smart events. Full functionality is not guaranteed with every third-party camera.
Storage and Recording-Retention Notice
Recording retention depends on the number of cameras, resolution, frame rate, bitrate, compression format, scene activity, recording schedule, smart-event configuration, hard-drive capacity, and storage redundancy settings.
Surveillance-grade hard drives are recommended. Hard drives are not included unless specifically stated in the selected product option.

Important Product Information
Specifications are subject to change without notice. Features, smart functions, camera compatibility, hard-drive support, storage capacity, recording performance, decoding capability, bandwidth, display output, mobile access, browser support, cloud functionality, and overall system performance may vary depending on firmware version, connected camera, hard-drive model, network configuration, installation environment, system settings, and regional product revision.
Smart analytics listed for this standard recorder are generated by compatible IP cameras and do not mean the recorder includes the same recorder-side analytics available on an IQ-series model. Always double-check the manufacturer’s current documentation and confirm system requirements before ordering.
NDAA status should be verified against the manufacturer’s latest compliance documentation before purchasing for government, public-sector, or compliance-sensitive projects.
