SolarNode Camera Control via Motion

This SolarNode plugin provides a component that can integrate with motion to support controlling a monitored camera.

Install

The plugin can be installed via the Plugins page on your SolarNode. It appears under the Control category as Camera Control via Motion. Once installed, a Camera Motion Detection Control component will become available.

Configuration

Each service configuration contains the following settings:

Setting	Description
Control ID	The ID to use for the SolarNode control.
Motion URL	The base URL to the motion web control API to integrate with.
Connection Timeout	A connection timeout to use for the motion web control API, in milliseconds.
Media Path	The path to the directory where motion is configured to save its captured images.
Media Filter	A regular expression to filter non-snapshot files in Media Path, so that only files matching the filter are considered as non-snapshot images.
Snapshot Media Filter	A regular expression to filter snapshot files in Media Path, so that only files matching the filter are considered as snapshot images.
Auto Snapshots	A configurable list of camera snapshot schedules, to take periodic snapshots from cameras.

Each Auto Snapshot configuration contains the following settings:

Setting	Description
Camera ID	The motion camera ID to request the snapshot for. Camera IDs start at 1 for the first camera.
Schedule	Either the frequency in seconds to capture snapshots at, or a cron expression.

Configuration notes

The Media Path setting allows this plugin to display the latest motion-detection and snapshot images created by the configured motion service, as long as that service is running on the same device as SolarNode and the path is accessible to the SolarNode runtime.

The Auto Snapshots feature allows you to create snapshot images from any camera connected to motion at a defined schedule. For example you can define the schedule as a simple number like 300 to take a snapshot every 5 minutes, or use a cron expression like 0 0 12 * * ? to take a snapshot at noon each day.

Instruction support

This component supports the Signal instruction. A snapshot signal name requests motion to capture a new snapshot image. Besides the required control ID parameter, an optional cameraId parameter can be included to request the snapshot from a specific motion camera. If no cameraId parameter is provided, a default of 1 is assumed.

For example, to request a snapshot from control /camera/1 camera ID 2 the following instruction parameters would be used:

Parameter	Value
parameters[0].name	/camera/1
parameters[0].value	snapshot
parameters[1].name	cameraId
parameters[1].value	2
