Why this recorder

High-Bandwidth 16-Channel PoE Recording

The NVR502-16B-P16 is designed for professional surveillance systems that need direct PoE camera connections, high-resolution recording, flexible storage and reliable remote access without requiring a separate PoE switch for the first 16 cameras.

16 Independent PoE Interfaces

Connect and power up to 16 compatible IP cameras directly from the recorder using IEEE 802.3af/at PoE.

320Mbps Incoming Bandwidth

Provides substantial network capacity for multi-camera systems using higher resolutions, frame rates and bitrates.

Up to 16MP Recording

Supports recording resolutions up to 16 megapixels, depending on camera, codec, stream settings and available recorder resources.

Dual Independent Displays

One HDMI and one VGA output support independent display configurations, with HDMI resolution up to 4K.

Two-Hard-Drive Storage

Two SATA interfaces support large-capacity surveillance storage, disk groups, redundant storage and RAID 1.

ANR Storage Protection

With compatible cameras, Automatic Network Replenishment can backfill video to the NVR after a temporary network interruption.

Smart Camera Events

Supports compatible camera-side analytics such as intrusion, cross-line, vehicle detection, people counting and video metadata.

Third-Party Camera Support

Supports mainstream ONVIF Profile S, G and T cameras plus RTSP, subject to third-party compatibility and feature limitations.

Built for Professional Surveillance Systems

Strong bandwidth, 16 built-in PoE ports, dual-drive storage, independent display outputs and extensive alarm connectivity make this recorder a practical choice for commercial systems requiring reliability and room for higher-resolution cameras.

16-Channel Synchronous PlaybackReview up to 16 supported channels at the same time.
RAID 1 SupportMirror compatible drives to improve storage redundancy.
8 Alarm Inputs / 2 OutputsIntegrate supported external sensors and alarm devices.
Remote User CapacitySupports up to 128 remote users under suitable network conditions.
Ultra 265 CompressionHelps reduce bandwidth and storage requirements with compatible UNV cameras.
Cloud Upgrade SupportSupports compatible cloud-based firmware upgrade workflows.

Important PoE Notice
