### addCamera

* **addCamera**(`opts`): `Promise<RoomSessionDevice>` - See [RoomSessionDevice documentation](/docs/browser-sdk/v3/js/reference/video/room-session-device) for more details.

Adds a camera device to the room. Using this method, a user can stream multiple video sources at the same time.

#### Parameters

<ParamField path="opts" type="MediaTrackConstraints & { autoJoin?: boolean }">
  Specify the constraints for the device. In addition, you can add the `autoJoin` key to specify whether the device should immediately join the room or joining will be performed manually later.
</ParamField>

#### Returns

`Promise<RoomSessionDevice>` - See [RoomSessionDevice documentation](/docs/browser-sdk/v3/js/reference/video/room-session-device) for more details.

#### Permissions

* `room.self.additional_source`

You need to specify the permissions when [creating the Video Room Token](/docs/apis/video/room-tokens/create-room-token) on the server side.

#### Examples

Adding any of the camera devices to the room (duplicate streams are possible):

```javascript
await roomSession.addCamera();
```

Adding a specific camera:

```javascript
await roomSession.addCamera({
  deviceId: "gOtMHwZdoA6wMlAnhbfTmeRgPAsqa7iw1OwgKYtbTLA=",
});
```

Adding a high-resolution camera, joining it manually:

```javascript
const roomDev = await roomSession.addCamera({
  autoJoin: false,
  width: { min: 1280 },
});
await roomDev.join();
```
