i-PRO WJ-NU201K 8-Channel PoE+ Network Video Recorder

Overview

The WJ-NU201K is a compact 8-channel network video recorder with integrated PoE+ (802.3at) power delivery, purpose-built for mid-scale surveillance deployments requiring efficient 4K/8MP recording without separate power infrastructure. The unit supports H.265 and H.264 codecs—H.265 reduces file size by approximately 50% versus H.264, meaningful when managing 24TB of storage across continuous multi-camera recording. Dual codec flexibility accommodates legacy ONVIF NVT-conformant cameras while allowing forward migration to newer i-PRO and third-party equipment. The 8-channel architecture fits standard retail, office, transportation, and facility monitoring layouts. Compact form factor (340 × 44 × 230 mm) and included DC 54V power adapter enable rapid deployment in network closets or control rooms with wall or rack mounting. NDAA-compliant with FIPS 140-2 Level 3 certification—required for federal and defense-adjacent installations.

Compatibility

Direct compatibility with i-PRO series network cameras and any ONVIF NVT-conformant camera or encoder. Supports all standard i-PRO pan/tilt/zoom models with full preset programming (up to 256 positions), auto-focus control, brightness adjustment, and auxiliary relay triggering. Records up to 60 fps per camera depending on source frame rate and image resolution. Aspect ratios supported include 4:3, 16:9, 1:1, and 9:16 to accommodate panoramic, traditional box, and narrow-field sensors. Audio format support includes AAC-LC and G.711 for ONVIF-compliant audio channels. Playback and live-view modes include 4/9 split-screen, wide-view sequences (2–9 screens), and independent sub-monitor cycling for distributed command-center workflows.

Installation Notes

Integrated PoE+ switch delivers up to 802.3at power per port—verify camera wattage against PoE+ availability to avoid oversubscription across all 8 channels. Built-in AC-to-DC adapter (DC 54V, 2.78A) ships with unit; no external PSU required. Wall or rack mount using standard M6 fasteners (torque specs and mounting template available in full datasheet). Pre-event recording up to 15 seconds supported for rapid incident capture when delivery speed from network camera exceeds 4 Mbps minimum threshold. Schedule up to 4 independent recording programs across 6 daily time zones per weekday configuration.
