# Edge Jetson Deploy

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

## Quick install

```bash
# 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`):

```bash
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:

```bash
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`:

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

Test before install:

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

---

## Cutover from MQTT frigate-counter

`install-services.sh` automatically:

1. Disables `frigate-counter` and `frigate-counter-dashboard`
2. Enables `jetson-counter` + `jetson-counter-dashboard`

Archive old DB (optional):

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

---

## Validation checklist

```bash
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

```bash
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:

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

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