The i-PRO WJ-NX510K is a high-capacity network video recorder engineered to manage 64 to 128 camera streams with advanced H.265 and H.264 compression, delivering enterprise-grade recording and playback performance for large-scale surveillance deployments.
This NVR supports 4K (8MP) resolution across multiple video streams, leveraging dual H.265 and H.264 codec flexibility to optimize storage efficiency and bandwidth utilization. The intelligent compression technology allows operators to maintain premium image quality while reducing storage footprint—critical for facilities managing dozens or hundreds of cameras simultaneously. The system handles real-time encoding and decoding across its full channel capacity, ensuring smooth, synchronized playback of multiple video sources without degradation.
The WJ-NX510K includes comprehensive PTZ (Pan/Tilt/Zoom) camera control capabilities, supporting preset position programming up to 256 unique locations per camera. Operators can trigger rapid position recalls, focus adjustment, brightness control, and zoom operations directly from the NVR interface. The display modes support both single-screen PTZ monitoring for focused tracking and 4-screen PTZ layouts for multi-camera oversight, providing flexible operator workflows across different monitoring tasks.
Full ONVIF compliance ensures seamless integration with third-party IP cameras and management platforms, eliminating vendor lock-in and enabling mixed-brand ecosystem deployments. This standardized protocol support simplifies system expansion and future upgrades without requiring proprietary licensing or specialized integrations.
Powered by universal AC input (100-240V, 50Hz/60Hz), the system accommodates regional electrical standards across diverse installation environments. The dual-voltage design eliminates the need for power conditioning equipment in most facilities, reducing deployment complexity and total cost of ownership.
Key Features:
- 64-128 channel capacity for enterprise-scale deployments
- 4K (8MP) native resolution support with H.265/H.264 dual codec
- Up to 256 programmable PTZ preset positions per camera
- ONVIF compatibility for third-party camera integration
- 1-screen and 4-screen PTZ display modes for flexible monitoring
- AC100-240V universal power input (50Hz/60Hz)

Expert Take from Ted Perry
The WJ-NX510K addresses the operational demands of large installations where camera count and codec flexibility are non-negotiable. H.265 dual-codec support is particularly valuable for environments with legacy H.264 deployments that are transitioning to newer infrastructure—you can mix codecs without performance penalties. The 256-preset PTZ capacity and ONVIF backbone make this recorder a solid anchor point for mixed-vendor camera strategies common in multi-site enterprises.
