+
+The `push` camera platform allows you to integrate images sent over HTTP POST to Home Assistant as a camera. External applications/daemons/scripts are therefore able to "stream" images through Home Assistant.
+
+Optionally the Push Camera can **buffer** a given number of images, creating an animation of the detected motion after the event has been recorded.
+
+Images are cleared on new events, and events are separated by a soft (configurable) **timeout**.
+
+## Integration with motionEye
+
+The `push` camera can as an example be used with [motionEye](https://github.com/ccrisan/motioneye/wiki) a web frontend for the motion daemon. motionEye is usually configured to save/record files ***only*** when motion is detected. It provides a hook to run a command whenever an image is saved, which can be used together with cURL to send the motion detected images to the `push` camera, as shown in this example:
+
+In motionEye, under **File Storage -> Run A Command** type in:
+```bash
+curl -X POST -F "image=@%f" http://my.hass.server.com:8123/api/camera_push/camera.push_camera
+```
+
+Please take note that you might need to add `-H "x-ha-access: YOUR_PASSWORD"` if you have API authentication enabled.
+
+Optionally configure motionEye to save only motion triggered images by going into **Still Images -> Capture Mode** and setting **Motion Triggered**. Tune your preferences under **Motion Detection**.
+
+In this setup, you can configure the push camera to continuously replay the last motion triggered event using a configuration such as:
+
+```yaml
+camera:
+  - platform: push
+    name: MotionEye Outdoor
+    buffer: 3
+    timeout: 5
+```
+
+## {% linkable_title Configuration %}
+
+To enable this camera in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+camera:
+  - platform: push
+    name: My Push Camera
+```
+
+{% configuration %}
+name:
+  description:  The name you would like to give to the camera.
+  required: false
+  default: Push Camera
+  type: string
+buffer:
+  description: Number of images to buffer per event. Be conservative, large buffers will starve your system memory.
+  required: false
+  default: 1
+  type: string
+timeout:
+  description: Amount of time after which the event is considered to have finished.
+  required: false
+  default: 5 seconds
+  type: time
+field:
+  description: HTTP POST field containing the image file
+  required: false
+  default: image
+  type: string
+{% endconfiguration %}
