In factory NVR scenarios, 99% of cameras are standard network cameras. They output H.265/H.264 streams over Ethernet and are pulled by NVRs or analytics servers via RTSP/ONVIF.
So the right way to evaluate the EA250 is: Ethernet access + RTSP/ONVIF + video decoding + AI compute.
2.What AI NVRs Really NeedTraditional NVRs only record and play back. AI NVRs analyze video in real time — detecting abnormal behavior, identifying safety hazards, and pushing alerts.
Industrial requirements differ from commercial security:
Orin NX supports 1× 8K30 / 2× 4K60 / 4× 4K30 / 9× 1080p60 / 18× 1080p30 H.265 decoding. Even with 15 cameras, the hardware decoder is not a bottleneck — decoding does not consume CPU or GPU, leaving AI inference free to run models.
Important distinction: 18-channel decoding is VPU capability. AI inference runs on the GPU. The practical EA250 configuration is 4–8 channels of 1080P real-time AI analysis, determined jointly by decoding and 157 TOPS inference.
4.How EA250 Matches4.1 Dual NICs: 1GbE for Management, 2.5GbE for Video
EA250 supports RTSP/ONVIF and pre-installed Ubuntu 22.04, so it can deploy standard frameworks such as NVIDIA DeepStream without replacing existing cameras or NVRs.
4.2 AI Inference: 157 TOPS for 4–8 Channels
Typical factory detection tasks include:
Huayue Machinery’s AI “three violations” capture system has already validated these scenarios, using an edge server as the brain to identify unsafe behavior with second-level discovery and immediate handling.
4.3 Storage: M.2 NVMe for Alarm Clips
EA250 offers an M.2 Key-M (2280) PCIe Gen4 x1 NVMe SSD slot with 128GB or 256GB options. Alarm clips (10–30 seconds before and after an event) are stored locally; only alarm information and structured data are uploaded.
NVMe advantages over mechanical HDDs:
Recommended retention: 7–30 days; external NAS via 2.5GbE for longer storage.
4.4 Real-Time Alarms
Via the Y-series IO board:
Network topology:
Factory cameras (4–8× 1080P) → Gigabit switch → EA250 2.5GbE (video)
EA250 1GbE → management network
EA250 pulls RTSP streams → VPU decode → GPU inference → DO/RS485/4G alarm
Software:
NVIDIA DeepStream for multi-stream decode, inference, and tracking
YOLO models for object detection
RTSP client and DO alarm linkage
Storage:
256GB M.2 NVMe SSD for local alarm clips, retained 7–30 days
Remote O&M:
Optional OOB out-of-band management and 4G/5G modules
