|
|
|
|
The ``esp32_camera`` component allows you to use ESP32-based camera boards in ESPHome that
|
|
directly integrate into Home Assistant through the native API.

Configuration variables:
|
|
------------------------
|
|
|
|
- **name** (**Required**, string): The name of the camera.
|
|
|
|
Connection Options:
|
|
|
|
- **data_pins** (**Required**, list of pins): The data lanes of the camera, this must be a list
|
|
of 8 GPIO pins.
|
|
- **vsync_pin** (**Required**, pin): The pin the VSYNC line of the camera is connected to.
|
|
- **href_pin** (**Required**, pin): The pin the HREF line of the camera is connected to.
|
|
- **pixel_clock_pin** (**Required**, pin): The pin the pixel clock line of the camera is connected to.
|
|
- **external_clock** (**Required**): The configuration of the external clock to drive the camera.
|
|
|
|
- **pin** (**Required**, pin): The pin the external clock line is connected to.
|
|
- **frequency** (*Optional*, float): The frequency of the external clock, must be either 20MHz
|
|
or 10MHz. Defaults to ``20MHz``.
|
|
|
|
- **i2c_pins** (**Required**): The I^2C control pins of the camera.
|
|
|
|
- **sda** (**Required**, pin): The SDA pin of the I^2C interface. Also called ``SIOD``.
|
|
- **scl** (**Required**, pin): The SCL pin of the I^2C interface. Also called ``SIOC``.
|
|
|
|
- **reset_pin** (*Optional*, pin): The ESP pin the reset pin of the camera is connected to.
|
|
If set, this will reset the camera before the ESP boots.
|
|
- **power_down_pin** (*Optional*, pin): The ESP pin to power down the camera.
|
|
If set, this will power down the camera while it is inactive.
|
|
- **test_pattern** (*Optional*, boolean): When enabled, the camera will show a test pattern
|
|
that can be used to debug connection issues.
|
|
|
|
Frame Settings:
|
|
|
|
- **max_framerate** (*Optional*, float): The maximum framerate the camera will generate images at.
|
|
Up to 60Hz is possible (with reduced frame sizes), but beware of overheating. Defaults to ``10 fps``.
|
|
- **idle_framerate** (*Optional*, float): The framerate to capture images at when no client
|
|
is requesting a full stream. Defaults to ``0.1 fps``.
|
|
- **resolution** (*Optional*, enum): The resolution the camera will capture images at. Higher
|
|
resolutions require more memory, if there's not enough memory you will see an error during startup.
|
|
|
|
- ``160x120`` (QQVGA)
|
|
- ``128x160`` (QQVGA2)
|
|
- ``176x144`` (QCIF)
|
|
- ``240x176`` (HQVGA)
|
|
- ``320x240`` (QVGA)
|
|
- ``400x296`` (CIF)
|
|
- ``640x480`` (VGA, default)
|
|
- ``800x600`` (SVGA)
|
|
- ``1024x768`` (XGA)
|
|
- ``1280x1024`` (SXGA)
|
|
- ``1600x1200`` (UXGA)
|
|
|
|
- **jpeg_quality** (*Optional*, int): The JPEG quality that the camera should encode images with.
|
|
From 10 (best) to 63 (worst). Defaults to ``10``.
|
|
|
|
- **contrast** (*Optional*, int): The contrast to apply to the picture, from -2 to 2. Defaults to ``0``.
|
|
- **brightness** (*Optional*, int): The brightness to apply to the picture, from -2 to 2. Defaults to ``0``.
|
|
- **saturation** (*Optional*, int): The saturation to apply to the picture, from -2 to 2. Defaults to ``0``.
|
|
- **vertical_flip** (*Optional*, bool): Whether to flip the image vertically. Defaults to ``true``.
|
|
- **horizontal_mirror** (*Optional*, bool): Whether to mirror the image horizontally. Defaults to ``true``.
|
|
|
|
.. note::
|
|
|
|
Camera uses PWM timer #1. If you need PWM (via the ``ledc`` platform) you need to manually specify
|
|
a channel there (with the ``channel: 2`` parameter)

Configuration for M5Stack Camera
|
|
--------------------------------
|
|
|
|
.. warning::
|
|
|
|
This camera board has insufficient cooling and will overheat over time,
|
|
ESPHome does only activate the camera when Home Assistant requests an image, but
|
|
the camera unit can still heat up considerably for some boards.
|
|
|
|
If the camera is not recognized after a reboot and the unit feels warm, try waiting for
|
|
it to cool down and check again - if that still doesn't work try enabling the test pattern.
