# Class: Camera
[Camera](../modules/camera.md).Camera
### A powerful `<Camera>` component.
The `<Camera>` component's most important (and therefore _required_) properties are:
* `device`: Specifies the [CameraDevice](../modules/cameradevice.md) to use. Get a [CameraDevice](../modules/cameradevice.md) by using the [useCameraDevices](../modules/hooks_usecameradevices.md#usecameradevices) hook, or manually by using the [Camera.getAvailableCameraDevices](camera.camera-1.md#getavailablecameradevices) function.
* `isActive`: A boolean value that specifies whether the Camera should actively stream video frames or not. This can be compared to a Video component, where `isActive` specifies whether the video is paused or not. If you fully unmount the `<Camera>` component instead of using `isActive={false}`, the Camera will take a bit longer to start again.
**`example`**
```jsx
function App() {
const devices = useCameraDevices('wide-angle-camera')
const device = devices.back
if (device == null) return <LoadingView />
return (
<Camera
style={StyleSheet.absoluteFill}
device={device}
isActive={true}
/>
)
}
```

## Properties
### context
• **context**: *any*
If using the new style context, re-declare this in your class to be the
`React.ContextType` of your `static contextType`.
Should be used with type annotation or static contextType.
```ts
static contextType = MyContext
// For TS pre-3.7:
context!: React.ContextType<typeof MyContext>
// For TS 3.7 and above:
declare context: React.ContextType<typeof MyContext>
```

## Methods
### UNSAFE\_componentWillMount
▸ `Optional`**UNSAFE_componentWillMount**(): *void*
Called immediately before mounting occurs, and before `Component#render`.
Avoid introducing any side-effects or subscriptions in this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use componentDidMount or the constructor instead
**`see`** https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#initializing-state
**`see`** https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#gradual-migration-path
**Returns:** *void*
Defined in: node_modules/@types/react/index.d.ts:716
___
### UNSAFE\_componentWillReceiveProps

Called when the component may be receiving new props.
React may call this even if props have not changed, so be sure to compare new and existing
props if you only want to handle changes.
Calling `Component#setState` generally does not trigger this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use static getDerivedStateFromProps instead

This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use getSnapshotBeforeUpdate instead

Avoid introducing any side-effects or subscriptions in this method.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use componentDidMount or the constructor instead; will stop working in React 17

Called when the component may be receiving new props.
React may call this even if props have not changed, so be sure to compare new and existing
props if you only want to handle changes.
Calling `Component#setState` generally does not trigger this method.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use static getDerivedStateFromProps instead; will stop working in React 17

Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call `Component#setState` here.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use getSnapshotBeforeUpdate instead; will stop working in React 17

Runs before React applies the result of `render` to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before `render` causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated
lifecycle events from running.

# Class: Camera
[index](../modules/index.md).Camera
### A powerful `<Camera>` component.
The `<Camera>` component's most important (and therefore _required_) properties are:
* `device`: Specifies the [CameraDevice](../modules/index.md#cameradevice) to use. Get a [CameraDevice](../modules/index.md#cameradevice) by using the [useCameraDevices](../modules/index.md#usecameradevices) hook, or manually by using the [Camera.getAvailableCameraDevices](index.camera.md#getavailablecameradevices) function.
* `isActive`: A boolean value that specifies whether the Camera should actively stream video frames or not. This can be compared to a Video component, where `isActive` specifies whether the video is paused or not. If you fully unmount the `<Camera>` component instead of using `isActive={false}`, the Camera will take a bit longer to start again.
**`example`**
```jsx
function App() {
const devices = useCameraDevices('wide-angle-camera')
const device = devices.back
if (device == null) return <LoadingView />
return (
<Camera
style={StyleSheet.absoluteFill}
device={device}
isActive={true}
/>
)
}
```
**`component`**

* *PureComponent*<[*CameraProps*](../modules/camera.md#cameraprops), CameraState\>
↳ **Camera**
## Constructors
### constructor
\+ **new Camera**(`props`: [*CameraProps*](../modules/camera.md#cameraprops)): [*Camera*](camera.camera-1.md)
#### Parameters:
Name | Type |
:------ | :------ |
`props` | [*CameraProps*](../modules/camera.md#cameraprops) |
**Returns:** [*Camera*](camera.camera-1.md)

## Properties
### context
• **context**: *any*
If using the new style context, re-declare this in your class to be the
`React.ContextType` of your `static contextType`.
Should be used with type annotation or static contextType.
```ts
static contextType = MyContext
// For TS pre-3.7:
context!: React.ContextType<typeof MyContext>
// For TS 3.7 and above:
declare context: React.ContextType<typeof MyContext>

Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use componentDidMount or the constructor instead
**`see`** https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#initializing-state
**`see`** https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#gradual-migration-path

Called when the component may be receiving new props.
React may call this even if props have not changed, so be sure to compare new and existing
props if you only want to handle changes.
Calling `Component#setState` generally does not trigger this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use static getDerivedStateFromProps instead

Called when the component may be receiving new props.
React may call this even if props have not changed, so be sure to compare new and existing
props if you only want to handle changes.
Calling `Component#setState` generally does not trigger this method.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps
prevents this from being invoked.
**`deprecated`** 16.3, use static getDerivedStateFromProps instead; will stop working in React 17

Runs before React applies the result of `render` to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before `render` causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated
lifecycle events from running.

Called to determine whether the change in props and state should trigger a re-render.
`Component` always returns true.
`PureComponent` implements a shallow comparison on props and state and returns true if any
props or states have changed.
If false is returned, `Component#render`, `componentWillUpdate`
and `componentDidUpdate` will not be called.

* `"dual-camera"`: A combination of wide-angle and telephoto cameras that creates a capture device.
* `"dual-wide-camera"`: A device that consists of two cameras of fixed focal length, one ultrawide angle and one wide angle.
* `"triple-camera"`: A device that consists of three cameras of fixed focal length, one ultrawide angle, one wide angle, and one telephoto.
* `"true-depth-camera"`: A combination of cameras and other sensors that creates a capture device capable of photo, video, and depth capture.
Defined in: [src/CameraDevice.ts:20](https://github.com/cuvent/react-native-vision-camera/blob/daa3c48/src/CameraDevice.ts#L20)
___
### PhysicalCameraDeviceType
Ƭ **PhysicalCameraDeviceType**: *ultra-wide-angle-camera* \| *wide-angle-camera* \| *telephoto-camera*
Indentifiers for a physical camera (one that actually exists on the back/front of the device)
* `"ultra-wide-angle-camera"`: A built-in camera with a shorter focal length than that of a wide-angle camera. (focal length between below 24mm)
* `"wide-angle-camera"`: A built-in wide-angle camera. (focal length between 24mm and 35mm)
* `"telephoto-camera"`: A built-in camera device with a longer focal length than a wide-angle camera. (focal length between above 85mm)

___
### VideoStabilizationMode
Ƭ **VideoStabilizationMode**: *off* \| *standard* \| *cinematic* \| *cinematic-extended* \| *auto*
Indicates a format's supported video stabilization mode
* `"off"`: Indicates that video should not be stabilized
* `"standard"`: Indicates that video should be stabilized using the standard video stabilization algorithm introduced with iOS 5.0. Standard video stabilization has a reduced field of view. Enabling video stabilization may introduce additional latency into the video capture pipeline
* `"cinematic"`: Indicates that video should be stabilized using the cinematic stabilization algorithm for more dramatic results. Cinematic video stabilization has a reduced field of view compared to standard video stabilization. Enabling cinematic video stabilization introduces much more latency into the video capture pipeline than standard video stabilization and consumes significantly more system memory. Use narrow or identical min and max frame durations in conjunction with this mode
* `"cinematic-extended"`: Indicates that the video should be stabilized using the extended cinematic stabilization algorithm. Enabling extended cinematic stabilization introduces longer latency into the video capture pipeline compared to the AVCaptureVideoStabilizationModeCinematic and consumes more memory, but yields improved stability. It is recommended to use identical or similar min and max frame durations in conjunction with this mode (iOS 13.0+)
* `"auto"`: Indicates that the most appropriate video stabilization mode for the device and format should be chosen automatically

### VideoStabilizationMode
Ƭ **VideoStabilizationMode**: *off* \| *standard* \| *cinematic* \| *cinematic-extended* \| *auto*

* `"off"`: Indicates that video should not be stabilized
* `"standard"`: Indicates that video should be stabilized using the standard video stabilization algorithm introduced with iOS 5.0. Standard video stabilization has a reduced field of view. Enabling video stabilization may introduce additional latency into the video capture pipeline
* `"cinematic"`: Indicates that video should be stabilized using the cinematic stabilization algorithm for more dramatic results. Cinematic video stabilization has a reduced field of view compared to standard video stabilization. Enabling cinematic video stabilization introduces much more latency into the video capture pipeline than standard video stabilization and consumes significantly more system memory. Use narrow or identical min and max frame durations in conjunction with this mode
* `"cinematic-extended"`: Indicates that the video should be stabilized using the extended cinematic stabilization algorithm. Enabling extended cinematic stabilization introduces longer latency into the video capture pipeline compared to the AVCaptureVideoStabilizationModeCinematic and consumes more memory, but yields improved stability. It is recommended to use identical or similar min and max frame durations in conjunction with this mode (iOS 13.0+)
* `"auto"`: Indicates that the most appropriate video stabilization mode for the device and format should be chosen automatically
