Edge Jetson Deploy

Production counter: direct LAN RTSP + YOLO11n TensorRT + SQLite batch store.
Replaces MQTT frigate-counter on the edge Jetson.

Quick install

# 1. Copy this folder to Jetson
sudo mkdir -p /opt/jetson-counter
sudo cp -r jetson-counter/* /opt/jetson-counter/
sudo chown -R jetson:jetson /opt/jetson-counter

# 2. Configure
cd /opt/jetson-counter
cp config.env.example .env
nano .env   # SOURCE, MODEL_PATH, CAMERA_NAME, etc.
sed -i 's/\r$//' .env

# 3. Venv + services
chmod +x setup-venv.sh install-services.sh
sudo ./setup-venv.sh
sudo ./install-services.sh

YOLO11n TensorRT engine (one-time)

On the Jetson (must match IMGSZ / HALF in .env):

source /opt/jetson-counter/venv/bin/activate
export PYTHONNOUSERSITE=1

yolo export model=/media/jetson/DATA/yolo11n.pt format=engine half=True imgsz=416 device=0

Verify classes:

PYTHONNOUSERSITE=1 python -c "
from ultralytics import YOLO
m = YOLO('/media/jetson/DATA/yolo11n.engine')
print(m.names)
"

Expect ayam and talenan.

Direct camera RTSP

Set in .env:

SOURCE=rtsp://user:pass@192.168.x.x:554/stream1

Test before install:

ffplay -rtsp_transport tcp -t 5 "$SOURCE"
nc -zv <camera-ip> 554

Cutover from MQTT frigate-counter

install-services.sh automatically:

Disables frigate-counter and frigate-counter-dashboard
Enables jetson-counter + jetson-counter-dashboard

Archive old DB (optional):

sudo cp /opt/frigate-counter/frigate_counter.db ~/frigate_counter.db.backup

Validation checklist

sudo systemctl is-active jetson-counter jetson-counter-dashboard
PYTHONNOUSERSITE=1 /opt/jetson-counter/venv/bin/python -c "import torch; print('cuda', torch.cuda.is_available())"
sudo journalctl -u jetson-counter -n 20 --no-pager

Good signs:

Stream ready!
Loaded engine size: ... MiB
Frame 100 | Batch ...

Logs & restart

sudo journalctl -u jetson-counter -f
sudo systemctl restart jetson-counter   # after .env change

JetPack 6.0 torch wheel

If setup-venv.sh fails on torch URL, list wheels:

curl -s https://developer.download.nvidia.com/compute/redist/jp/v60/pytorch/ | grep cp310

Set TORCH_WHEEL_URL=... when running setup-venv.sh.
