Camera Proxy


The proxy camera platform allows you to pass another camera’s output through post-processing routines and generate a new camera with the post-processed output.

The current post-processing supports resizing and/or cropping the image/MJPEG as well as limiting the maximum refresh rate.

The current proxy capabilities are intended to reduce the camera bandwidth for slower internet connections.

Configuration

To enable this camera in your installation, you must first have an existing working camera configured in Home Assistant. Next, add the following to your configuration.yaml file:

# Example configuration.yaml entry
camera:
  - platform: proxy
    entity_id: camera.<existingcamera>
    max_stream_width: 360
    max_image_width: 720

Configuration Variables

entity_id stringRequired

The ID of another Home Assistant camera to post-process.

name string(Optional)

This parameter allows you to override the name of your camera.

mode string(Optional, default: resize)

The operating mode, either resize or crop.

max_image_width integer(Optional)

The maximum width of single images taken from the camera (aspect ratio will be maintained on resize processing).

max_image_height integer(Optional)

The maximum height of single images taken from the camera, only used for crop operations. If not provided, the original height is assumed by default.

max_stream_width integer(Optional)

The maximum width of the MJPEG stream from the camera (aspect ratio will be maintained on resize processing).

max_stream_height integer(Optional)

The maximum height of the MJPEG stream from the camera, only used for crop operations. If not provided, the original height is assumed by default.

image_top integer(Optional, default: 0)

The top (y) coordinate to be used as a starting point for crop operations.

image_left integer(Optional, default: 0)

The left (x) coordinate to be used as a starting point for crop operations.

image_quality integer(Optional, default: 75)

The quality level used for resulting JPEG for snapshots.

stream_quality integer(Optional, default: 75)

The quality level used for resulting MJPEG streams.

image_refresh_rate float(Optional)

The minimum time in seconds between generating successive image snapshots.

force_resize boolean(Optional, default: false)

Resize the image even if the resulting image would take up more bandwidth than the original.

cache_images boolean(Optional, default: false)

Preserve the last image and re-send in the case the camera is not responding.

Examples

Example of using two Camera proxies along with a Foscam camera:

camera:
  - platform: foscam
    ip: 192.168.1.10
    username: foscam_camera
    password: camera_password
    name: mycamera
  - platform: proxy
    entity_id: camera.mycamera
    max_stream_width: 360
    max_image_width: 480
    image_refresh_rate: 5.0
  - platform: proxy
    entity_id: camera.mycamera
    name: My cropped camera
    mode: crop
    max_image_width: 480
    max_image_height: 320
    image_left: 100
