Network Video Recorder i-PRO WJ-NU301KG — 16‑channel NVR with built‑in PoE+ switch, 3840×2160 max, SATA HDD up to 40 TB

The i-PRO WJ-NU301KG is a 16-channel network video recorder (NVR) with an integrated PoE+ switch, designed for multi-camera surveillance systems in commercial and larger residential installations. It accepts IP camera connections directly via the built-in PoE+ ports, supports video input resolutions up to 3840×2160, and stores recorded footage on internal SATA 3.5" hard drives with total capacity up to 40 TB. Network interfaces support 10/100/1000 Mbit/s and both IPv4 and IPv6 addressing. Audio is supported in AAC-LC and G.711 formats to capture synchronized audio streams alongside video.

Advantages

Integrated PoE+ switch eliminates the need for separate power injectors or midspans, simplifying installation and cable management for up to 16 cameras. High-resolution input up to 3840×2160 enables detailed recording suitable for identification and evidence capture. Large internal storage capacity support — up to 40 TB on SATA drives — provides extended retention periods without relying exclusively on external storage. Dual-stack network support (IPv4/IPv6) and gigabit Ethernet connectivity ensure compatibility with modern networks and reliable remote access.

Suitable for

• Retail stores and shopping centers requiring multi-camera coverage
• Office buildings and corporate campuses with centralized surveillance
• Large residential properties and gated communities
• Warehouses and logistics facilities monitoring goods and operations
• Educational institutions and public buildings needing continuous recording

How to use

Install the i-PRO WJ-NU301KG in a secure, well-ventilated location and mount compatible SATA 3.5" drives following the manufacturer’s instructions. Connect IP cameras to the PoE+ ports using appropriate CAT5e/CAT6 cable; the built-in PoE+ switch will supply power and network connectivity. Configure network settings to match your local network addressing (IPv4 or IPv6) and set up recording schedules, motion detection or continuous recording through the recorder’s management interface. Ensure audio channels are enabled and matched to corresponding camera streams if audio recording is required.

Recommendations

Use quality surveillance-grade SATA drives rated for continuous operation and implement a backup or archiving strategy for critical footage. Place the recorder in a controlled environment with stable temperature and power protection, and regularly verify firmware updates and access credentials to maintain security and reliability.
