+The `Xeoma` camera platform allows you to view the video feeds from a [Xeoma](http://felenasoft.com/xeoma) video surveillance server.
+
+To enable Xeoma camera feeds, add the following lines to your `configuration.yaml`:
+
+```yaml
+# Example configuration.yaml entry
+camera:
+  - platform: xeoma
+    host: http://localhost:10090
+```
+
+{% configuration %}
+host:
+  description: The URL of the Xeoma server's web interface.
+  required: true
+  type: string
+username:
+  description: The username used to access the Xeoma server's web interface.
+  required: false
+  type: string
+password:
+  description: The password used to access the Xeoma server's web interface.
+  required: false
+  type: string
+new_version:
+  description: Set to false if the Xeoma server version is 17.5 or earlier.
+  required: false
+  default: true
+  type: boolean
+cameras:
+  description: List of customizations for individual Xeoma cameras.
+  required: false
+  type: list
+  keys:
+    image_name: 
+      description: The name of the JPEG image for this camera as configured in Xeoma (without .jpg extension).
+      required: true
+      type: string
+    name:
+      description: The name to display in the frontend for this camera.
+      required: false
+      default: The `image_name` for this camera.
+      type: string
+    hide:
+      description: Don't show this camera in Home Assistant.
+      required: false
+      default: false
+      type: boolean
+{% endconfiguration %}
+
+## {% linkable_title Full examples %}
+
+```yaml
+# Example configuration.yaml entry
+camera:
+  - platform: xeoma
+    host: http://localhost:10090
+    username: user
+    password: secretpassword
+    new_version: false
+    cameras:
+      - image_name: front_porch
+        name: Front Porch
+      - image_name: back_patio
+        hide: true
+```
+
+To use this platform, you must have the Xeoma Web Server module enabled in at least one of your camera chains.
+ 
+This platform will parse the Xeoma web interface to find all enabled cameras and add them all to Home Assistant. You can 
+hide individual cameras using the platform configuration.
+ 
+The `image_name` configuration value for each camera should match the name supplied to the Xeoma Web Server configuration (under _Path to access images_) with the _.jpg_ extension removed.
