i-PRO WJ-NU300K 16-Channel PoE+ Network Video Recorder
Overview
The WJ-NU300K is a 16-channel network video recorder built for mid-to-large enterprise surveillance deployments where bandwidth efficiency and storage cost matter. It accepts 4K/8MP resolution streams from i-PRO and ONVIF-compatible cameras, recording up to 16 concurrent feeds via dual H.265/H.264 codec support. H.265 (HEVC) cuts bitrate roughly 50% versus H.264 at equivalent quality—a tangible saving when recording 24/7 across dozens of cameras or managing limited WAN backhaul. The unit ships with a DC 54V power adapter (2.78A included), eliminating separate PSU procurement. Supports wall-mount or rack-mount installation, fitting network closets, server rooms, or on-site control centers. ONVIF protocol compatibility enables mixed-vendor camera integration alongside i-PRO models.
Compatibility
Accepts video streams from i-PRO network cameras and any ONVIF NVT-conformant IP camera or encoder. Supports up to 16 concurrent camera channels. Records at frame rates up to 60 fps per camera (subject to network bandwidth and camera capability). Handles multiple aspect ratios: 4:3 (up to 3072×2304), 16:9 (up to 3840×2160), 1:1, and 9:16 portrait modes. Audio input supported via AAC-LC or G.711 codecs from compatible sources. Playback control includes standard VCR-style functions: play, reverse play, pause, fast-forward, fast-reverse, frame-by-frame navigation, and date/time search. Multiscreen display modes available: 4/9/16 split-screen on main monitor and 1-screen sequence or 4/9/16 split on sub-monitor for distributed control environments.
Installation Notes
Dimensions: 340mm (W) × 44mm (H) × 230mm (D)—compact form factor for shallow rack deployment or wall mounting. Requires standard 120/240V AC outlet for included power adapter; outputs regulated 54V DC to the NVR. NDAA-compliant unit with Intel CPU and FIPS 140-2 Level 3 certification—meets U.S. federal procurement requirements. Supports up to 24TB HDD capacity for long-term retention planning. Pre-event recording (up to 15 seconds at <4 Mbps per camera) available during event-triggered operation to capture activity preceding alarm conditions. Camera control features enable pan/tilt/zoom command, focus and brightness adjustment, and up to 256 programmable PTZ preset positions with auto-mode and click-centering for field operator convenience.
