The Google Nest Cam with floodlight is supported in the Smart Device Management (SDM) API. This device returns a device type of CAMERA:

sdm.devices.types.CAMERA

Traits

Reference

The following traits, commands, or events are related to this device:

Trait	Description	Commands	Events
CameraLiveStream	This trait belongs to any device that supports live streaming.	GenerateWebRtcStream ExtendWebRtcStream StopWebRtcStream
CameraMotion	This trait belongs to any device that supports motion detection events.		Motion
CameraPerson	This trait belongs to any device that supports person detection events.		Person
Info	This trait belongs to any device for device-related information.

JSON

The absence of a trait in a GET response indicates that the trait or feature is not currently available for the device. See Device types for more information.

Handle camera events

The following events may be triggered from a CAMERA device type or a DOORBELL or DISPLAY that features a camera, such as the Google Nest Doorbell (legacy) or Google Nest Hub Max :

Type	Element	Description
Event	Motion event of the CameraMotion trait	Motion has been detected by the camera.
Event	Person event of the CameraPerson trait	A person has been detected by the camera.

For example, here the camera has detected motion:

Access a live stream

The live stream from a camera can be accessed. The following stream formats are supported for this device:

WebRTC

For a full list of cameras and supported stream formats, see Supported Devices.

To access a live stream, use the appropriate GenerateFormatStream command of the CameraLiveStream trait.

WebRTC

For a WebRTC stream, send an offerSdp in the GenerateWebRtcStream command of the CameraLiveStream trait to get an answerSdp:

Request

POST /enterprises/project-id/devices/device-id:executeCommand
{
  "command" : "sdm.devices.commands.CameraLiveStream.GenerateWebRtcStream",
  "params" : {
    "offerSdp" : "offerSdp"
  }
}

Response

{
  "results" : {
    "answerSdp" : "answerSdp",
    "expiresAt" : "2020-01-04T18:30:00.000Z",
    "mediaSessionId" : "Jg0xSEDCJuJmDe2kohZ1TyNdWU..."
  }
}

We recommend using the Web Application Sample to learn how to generate a successful live stream. This sample generates a valid offerSdp that meets all the SDP offer restrictions for Nest cameras.

An SDP offer for Nest cameras must meet the following restrictions:

Only the Unified format is supported. Plan B is not supported.
All media lines (m=) must be present in the offer and must be in this order:
1. audio
2. video
3. application
Trickle ICE is supported, but not required.
Only the Opus codec is supported for audio.
The audio setting must be set to a=recvonly (receive only).
The offer must end with a newline character of either \r\n or \n.

The answerSdp must be used to generate the live stream within 30 seconds of receiving the response, otherwise it expires. If it expires, execute the GenerateWebRtcStream command again to receive a new answerSdp.

When opening WebRTC channels for the live stream, make sure to create a data channel as well as a video channel.

Extend a live stream

Camera live stream sessions are only valid for 5 minutes. If you need to extend the lifetime of a live stream, use the appropriate ExtendFormatStream command of the CameraLiveStream trait for the stream format you generated.

WebRTC

Wired

A WebRTC stream can only be extended on wire-powered cameras. A battery-powered camera is considered wire-powered while plugged in for charging. If the camera is on battery power, a request to extend an active WebRTC stream will be ignored.

To extend a WebRTC stream, specify the media session ID of the stream with the ExtendWebRtcStream command of the CameraLiveStream trait:

Request

POST /enterprises/project-id/devices/device-id:executeCommand
{
  "command" : "sdm.devices.commands.CameraLiveStream.ExtendWebRtcStream",
  "params" : {
    "mediaSessionId" : "Jg0xSEDCJuJmDe2kohZ1TyNdWU..."
  }
}

Response

{
  "results" : {
    "expiresAt" : "2018-01-04T18:30:00.000Z",
    "mediaSessionId" : "Jg0xSEDCJuJmDe2kohZ1TyNdWU..."
  }
}

Stop a live stream

Any time you are no longer using a camera live stream, you should stop it and invalidate the stream. To do so, use the appropriate StopFormatStream command of the CameraLiveStream trait for the stream format you generated.

WebRTC

To stop a WebRTC stream, specify the media session ID with the StopWebRtcStream command of the CameraLiveStream trait:

Request

POST /enterprises/project-id/devices/device-id:executeCommand
{
  "command" : "sdm.devices.commands.CameraLiveStream.StopWebRtcStream",
  "params" : {
    "mediaSessionId" : "Jg0xSEDCJuJmDe2kohZ1TyNdWU..."
  }
}

Response

{}

Errors

The following error code(s) may be returned in relation to this device:

Error Message	RPC	Troubleshooting
Invalid Offer SDP.	`INVALID_ARGUMENT`	Offer SDP audio must be set to `a=recvonly` (receive only).
Invalid Offer SDP is missing CRLF.	`INVALID_ARGUMENT`	The newline character is missing at the end of the `offerSdp` string when attempting to generate a WebRTC stream. Make sure the `offerSdp` string ends with `\r\n` or `\n` and try to generate the stream again.
Invalid Offer SDP m-lines.	`INVALID_ARGUMENT`	Offer SDP must contain all three of the audio, video, and application m-lines in that order.
Failed to retrieve answer SDP due to timeout.	`DEADLINE_EXCEEDED`	Try to generate the WebRTC live stream again.
