 Home Assistant will serve the images via its server, making it possible to view your IP cameras while outside of your network. The endpoint is `/api/camera_proxy/camera.[name]`.
 
-## Configuration
+{% include integrations/config_flow.md %}
 
-To enable this camera in your installation, add the following to your `configuration.yaml` file:
+You must enter a URL in at least one of the fields **Still Image URL** or **Stream Source URL**, the others are optional.
 
-```yaml
+[Templates](/topics/templating/) are allowed in the URL fields, which can be used to select different images or parameterize the URL depending on the status of sensors.  Template validity and network access are checked during the configuration steps.
-# Example configuration.yaml entry
-camera:
-  - platform: generic
-    still_image_url: http://194.218.96.92/jpg/image.jpg

 ### Local image
 
 You can show a static image with this platform. Just place the image here: `/config/www/your_image.png`
 
-```yaml
+- Still Image URL: `https://127.0.0.1:8123/local/your_image.png`
-camera:
-  - platform: generic
-    name: Some Image
-    still_image_url: https://127.0.0.1:8123/local/your_image.png

 ### Sharing a camera feed from one Home Assistant instance to another
 
 If you are running more than one Home Assistant instance (let's call them the 'host' and 'receiver' instances) you may wish to display the camera feed from the host instance on the receiver instance. You can use the [REST API](https://developers.home-assistant.io/docs/api/rest/#get-apicamera_proxycameraentity_id) to access the camera feed on the host (IP address 127.0.0.5) and display it on the receiver instance by configuring the receiver with the following:
 
-```yaml
+- Still Image URL: `https://127.0.0.5:8123/api/camera_proxy/camera.live_view`
-camera:
-  - platform: generic
-    name: Host instance camera feed
-    still_image_url: https://127.0.0.5:8123/api/camera_proxy/camera.live_view
-```
 
 ### Image from HTTP only camera
 
 To access a camera which is only available via HTTP, you must turn off SSL verification.
 
-```yaml
+- Still Image URL: `http://example.org/your_image.png`
-camera:
-  - platform: generic
-    name: Some Image
-    still_image_url: http://example.org/your_image.png
-    verify_ssl: false
-```
 
 ### Live stream
 
 To access a camera that has both a snapshot and live stream URL, utilizing the [stream](/integrations/stream/) component.
 
-```yaml
+- Still Image URL: `http://194.218.96.92/jpg/image.jpg`
-camera:
+- Stream Source: `rtsp://user:pass@194.218.96.92:554`
-  - platform: generic
-    name: Streaming Enabled
-    still_image_url: http://194.218.96.92/jpg/image.jpg
-    username: user
-    password: pass
-    stream_source: rtsp://user:pass@194.218.96.92:554
-```
 
 If a camera only has a live stream URL and no snapshot URL, the [stream](/integrations/stream/) component can also generate still images from the live stream URL.
 
-```yaml
+- Stream Source: `rtsp://user:pass@194.218.96.92:554`
-camera:
-  - platform: generic
-    name: Streaming
-    stream_source: rtsp://user:pass@194.218.96.92:554
-```
 
 ### Secured access to the camera
 
 To access a camera that requires secured access for still image or live stream (an HIK in my case).
 
-```yaml
+- Still Image URL: `http://192.168.1.100/ISAPI/Streaming/Channels/101/picture`
-camera: 
+- Stream Source: `rtsp://USERNAME:PASSWORD@192.168.1.100:554/Streaming/Channels/102`
-  - platform: generic
+- Verify SSL: `false`
-    still_image_url: "http://192.168.1.100/ISAPI/Streaming/Channels/101/picture"
+- Username: `user`
-    stream_source: "rtsp://USERNAME:PASSWORD@192.168.1.100:554/Streaming/Channels/102"
+- Password: `pass`
-    name: "My Camera"
+- Authentication: `digest`
