Product Details & Technical Specifications
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.
NDAA Compliant
The NVR502-16B-IQ appears on Uniview USA’s current NDAA-compliant product list.
