AI NVR with Jetson Orin

Deploys a local AI NVR using NVIDIA VST and Jetson Platform Services. DeepStream performs pedestrian detection; results display alongside the original video stream on the VST video wall.

Hardware: Jetson Orin device (e.g. reServer Industrial J4012), IP camera, network Software: JetPack 6.0 (L4T r36.3)

---

Execution model

Run one phase at a time. After each phase:

• If output contains [STOP] → stop immediately, consult the failure decision tree
• If output ends with [OK] → tell the user "Phase N complete" and proceed

---

Phase 1 — prerequisites check (~30 s)

Confirm JetPack 6.0:

cat /etc/nv_tegra_release
# Expected: R36 (release), REVISION: 3.0

Confirm IP camera is reachable:

ping -c 2 <CAMERA_IP>

[OK] when JetPack 6.0 confirmed and camera responds. [STOP] if JetPack version is wrong or camera unreachable.

---

Phase 2 — install Jetson Platform Services (~2 min)

sudo apt update
sudo apt install -y nvidia-jetson-services

Verify services are available:

ls /opt/nvidia/jetson/services/

Expected: directories including ingress/, vst/, etc. [OK]

---

Phase 3 — configure ingress & storage (~1 min)

Create the AI NVR nginx config:

sudo tee /opt/nvidia/jetson/services/ingress/config/ai-nvr-nginx.conf > /dev/null << 'EOF'
location /emdx/ {
    rewrite ^/emdx/?(.*)$ /$1 break;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    access_log /var/log/nginx/access.log timed_combined;
    proxy_pass http://emdx_api;
}

location /ws-emdx/ {
    rewrite ^/ws-emdx/?(.*)$ /$1 break;
    proxy_set_header Host $host;
    proxy_pass http://emdx_websocket;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}
EOF

(Optional) Modify VST storage path:

sudo nano /opt/nvidia/jetson/services/vst/config/vst_storage.json
# Change data_path and video_path as needed
