i-PRO WJ-NU301K 16-Channel PoE+ Network Video Recorder
Overview
The WJ-NU301K is a 16-channel network video recorder built for enterprise surveillance deployments requiring consolidated power delivery and storage scaling. This unit integrates a built-in PoE+ switch, eliminating the need for a separate managed switch in medium-scale installations — all 16 cameras draw power through a single device, reducing rack clutter and simplifying installation in security control rooms, facility offices, and distributed monitoring points. Support for both H.265 and H.264 codecs lets you mix legacy and modern cameras without compatibility friction; H.265 cuts storage costs roughly in half compared to H.264 when recording at the same frame rate and resolution.
Compatibility
The WJ-NU301K works with i-PRO series network cameras and any ONVIF NVT conformant camera or encoder from third-party vendors. This means you can deploy a mix of i-PRO PTZ and fixed cameras alongside compatible models from other manufacturers without vendor lock-in. Camera control includes pan/tilt, zoom, focus, brightness adjustment, and up to 256 preset position programs — useful for large-scale facilities where operators need quick camera positioning without manual adjustment. The unit supports up to 4K (8MP) image resolution across any combination of connected cameras and handles up to 60 fps per camera depending on your network bandwidth and HDD throughput.
Storage and Recording
The WJ-NU301K accepts up to 48TB of HDD capacity, supporting continuous 24/7 recording across all 16 channels or flexible event-based recording with 15-second pre-alarm buffering. Four independent recording schedules with six time zones per day let you tailor retention policies to different facility zones — for example, high-traffic areas might record 24/7 while backup areas record only during business hours. Scheduled sub-stream recording reduces storage overhead for lower-priority camera feeds.
Security and Compliance
NDAA-compliant design with Intel CPU and FIPS 140-2 Level 3 certification meets federal procurement requirements for sensitive installations. Power input accepts standard North American / Asian AC supply (100–240V, 50/60Hz), and the unit mounts to a wall or standard 19-inch rack with 4GB onboard memory for stable operation during network interruptions.
