# Camera Overlays

The ARK Jetson PAB Carrier V3 has **2× dual-lane CSI ports** on 22-pin FFC connectors. Camera configuration is managed through device tree overlays, and the image ships with the **IMX219 dual** overlay active — IMX219 cameras work on both ports out of the box.

## Supported Cameras

| Sensor | Resolution | Overlay            | Status            |
| ------ | ---------- | ------------------ | ----------------- |
| IMX219 | 3280x2464  | Camera IMX219 Dual | Working (default) |
| IMX477 | 4056x3040  | Camera IMX477 Dual | Working           |
| IMX708 | 4608x2592  | Camera IMX708 Dual | Working           |

See [cameras.md](https://github.com/ARK-Electronics/ark_jetson_kernel/blob/main/docs/cameras.md) in the kernel repo for sensor details, verification commands, and known issues.

## Switching Overlays

List the overlays available on your Jetson:

```bash
sudo /opt/nvidia/jetson-io/config-by-hardware.py -l
```

Apply one and reboot:

```bash
sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="Camera IMX477 Dual"
sudo reboot
```

## Verifying a Camera

Check that the sensor is detected:

```bash
nvargus_nvraw --lps
```

ARK-OS also ships `check_cameras.sh` (on `PATH`) which stream-tests every connected CSI camera, and the [ARK-UI](http://jetson.local) **Video** page shows a live stream of the first camera.

## Custom Overlays

To build your own camera overlay — or install one on an already-flashed system — follow [camera\_overlays.md](https://github.com/ARK-Electronics/ark_jetson_kernel/blob/main/docs/camera_overlays.md) in the kernel repo.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.arkelectron.com/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier-v3/hardware/camera-overlays.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
