Important PoE Notice

The NVR502-16B-IQ has no built-in PoE camera ports. All cameras must connect through external PoE switches, PoE injectors, network switches, fiber uplinks, or other properly designed network infrastructure. Confirm total camera bitrate, switch PoE budget, uplink speed, VLAN design, and network topology before ordering.

Recorder-Side AI Search and Analytics

The IQ platform adds AcuSearch, AcuTrack, image search, vehicle comparison, face detection, Smart Intrusion Prevention, and Ultra Motion Detection. Only one recorder-side analyzer mode can be active at a time. Enabling Smart On reduces incoming bandwidth from 320Mbps to 160Mbps, so system design must account for the selected operating mode.

Key Features

AcuSearch and AcuTrack

Search and follow human or vehicle targets across recordings from compatible UNV SIP and UMD cameras.

Recorder-Side AI Analytics

Supports face detection, Smart Intrusion Prevention, and Ultra Motion Detection in supported analyzer modes.

320Mbps Smart-Off Bandwidth

Provides up to 320Mbps incoming bandwidth when recorder-side smart processing is disabled.

External PoE Switch Required

This model has no built-in PoE camera ports. Cameras must connect through external PoE switching or network infrastructure.

Two SATA HDD Bays

Supports two hard drives, disk groups, redundant storage, RAID 1, and ANR.

Hard Drives Are Not Automatically Included

Unless the listing specifically states otherwise, surveillance hard drives are sold separately. Confirm the current UNV-compatible drive list, individual drive capacity, operating-temperature limitations, and retention requirements before ordering.

Smart Mode and Compatibility Notice

Recorder-side analyzer modes cannot operate simultaneously. AcuSearch and AcuTrack require compatible UNV SIP or UMD cameras. Third-party cameras may require manual configuration, and smart events, metadata, audio, alarms, image search, and firmware management may be limited.

Installation Tip

Design the system around external PoE switches and the selected AI operating mode. Confirm camera bitrate, Smart-On bandwidth, switch PoE budget, uplinks, VLANs, fiber links, storage retention, RAID design, UPS capacity, remote-viewing bandwidth, and camera compatibility before installation.

3-Year UNV Manufacturer Warranty

This product includes a three-year UNV manufacturer equipment warranty when purchased through NSI Security, subject to applicable warranty terms, eligibility, exclusions, serial-number verification, and return procedures.

Note: Specifications, AI capacities, bandwidth, decoding, HDD compatibility, analytics, search functions, and NDAA status are subject to firmware, region, and manufacturer changes. Smart-On mode reduces incoming bandwidth to 160Mbps. This recorder has no built-in PoE ports. Verify current official Uniview specifications and external PoE network requirements before ordering.

Important product information: Specifications are subject to change without notice. Features, storage support, audio functions, image performance, PoE behavior, compatibility and overall system performance may vary depending on firmware, recorder model, installation environment, network setup and system configuration. NVRs do not include hard drives unless explicitly stated.
