Unifi Protect Event Manager

The Unifi Protect Event Manager is a Flask-based service that integrates with UniFi Protect to manage and trigger video exports based on events like motion detection or doorbell rings. It allows for controlling video recording events by specifying past and future times and filtering cameras.

Here’s the updated Features section to include the new functionality of combining exported files:

---

Features

• Event Management: Start, extend, or cancel video recording events.
• Multiple Camera Support: Trigger events for one or multiple cameras.
• Flexible Timing: Configure how far back and how far into the future to record.
• Video File Combination: Automatically combine exported video files from the same camera into a single file based on timestamps.
• Manage Original Files: Choose whether to delete or keep the original split video files after combination using the UPEM_KEEP_SPLIT_FILES environment variable.
• Status Logging: Periodically logs the status of active events, including remaining time, start/end times, and involved cameras.
• Home Assistant Integration: Easily trigger events from Home Assistant automation.
• Dockerized Deployment: Easily deploy via Docker Compose.

How it Works

The service runs as a Flask web app, exposing several API endpoints to manage events. Events represent time periods during which video footage from one or more UniFi cameras is exported. These events can be started, extended, or canceled.

Each event has a start time, an end time, a list of cameras, and an associated identifier. Events can be managed via the following operations:

• Start/Extend Event: Create or extend an event by specifying how many minutes in the past and future to record.
• Cancel Event: Cancel a running event before it completes.
• View Status: View the status of all running events, including remaining time, start/end time, and cameras.

The system is designed to periodically log the current status of active events and automatically delete them once they are complete.

Video Export Using Protect-Archiver

This project integrates with unifitoolbox/protect-archiver, a command-line utility for managing UniFi Protect recordings. Protect-archiver enables seamless downloading, listing, and deleting video footage from UniFi Protect systems.

How Protect-Archiver is Used in This Project

By leveraging protect-archiver, this service automates the video export process when events are triggered via the API. Here’s how it works:

1. Event Handling: When an event is started or extended through the API, the system calculates the appropriate start and end times for the video export.
2. Dynamic Command Construction: Based on the event details, the system constructs a protect-archiver command to export video footage. This includes defining the time range and selecting the cameras involved.
3. Background Execution: The service executes the protect-archiver command in the background, ensuring the video is downloaded to a specified output folder.
4. Camera Selection: Users can specify which cameras to include in the export. If no cameras are provided, the system defaults to exporting footage from all cameras.

Example Command

Here’s an example of a protect-archiver command dynamically generated by the system for video export:

protect-archiver download \
  --address <UNIFI_PROTECT_ADDRESS> \
  --username <UNIFI_PROTECT_USERNAME> \
  --password <UNIFI_PROTECT_PASSWORD> \
  --start <start_time> \
  --end <end_time> \
  --cameras=<cameras> \
  --no-use-subfolders <output_folder>

• <UNIFI_PROTECT_ADDRESS>: The IP or domain of your UniFi Protect system.
• <start_time> and <end_time>: Time range for the export, calculated dynamically based on the event.
• <cameras>: A list of camera IDs to include in the export. If not specified, all cameras will be included.
• <output_folder>: The folder where the exported footage is saved.

Why Protect-Archiver?

Using protect-archiver allows this service to streamline interactions with UniFi Protect, making it easy to manage video exports with precise control over time periods and with cameras. Whether for security, event monitoring, or archival purposes, this integration automates the process and simplifies video management.

Home Assistant Integration

This system can be easily integrated into Home Assistant to trigger video exports based on motion or other triggers.

REST Command

In Home Assistant, set up a REST command to trigger UniFi Protect Event Manager events.

1. Add the following to your configuration.yaml:

rest_command:
  start_unifi_protect_event:
    url: "http://<server_ip>:8888"
    method: POST
    headers:
      content-type: "application/json"
    payload: >
      {
        "identifier": "{{ identifier }}",
        "past_minutes": {{ past_minutes }},
        "future_minutes": {{ future_minutes }},
        "cameras": [ {% for camera in cameras %} "{{ camera }}"{% if not loop.last %}, {% endif %}{% endfor %} ]
      }

Automation Example

You can trigger the REST command in an automation based on motion or other sensors:

alias: Trigger Video Export on Motion
trigger:
  - platform: state
    entity_id: binary_sensor.front_door_motion
    to: 'on'
action:
  - service: rest_command.start_unifi_protect_event
    data:
      identifier: "front_door_motion"
      past_minutes: 5
      future_minutes: 5
      cameras:
        - 65eb91b702d34c03e40316c2

This automation starts an event to export video footage from the past 5 minutes and future 5 minutes when motion is detected.

The home page provides an intuitive interface for starting, extending, and canceling video recording events. Here’s a breakdown of the different sections and functionality available:

Running Events Table

• Event Identifier: A unique identifier for each event, either auto-generated or user-provided.
• Start Time: The time when the event was started.
• End Time: The time when the event will end.
• Remaining Time: The time remaining before the event completes.
• Cameras: This field lists the camera IDs involved in the event. If no specific cameras are provided, "All Cameras" is displayed.
• Actions: Two buttons allow you to Extend or Cancel an event. When extended, the event continues recording for the minutes specified in the Future Minutes field.

Controls Section

This section allows you to create or extend a recording event for specific cameras.

• Event Identifier: A text input where you can specify a unique identifier for your event.
• Past Minutes: Input the number of minutes in the past that should be included in the recording. This is useful for capturing footage just before the event is triggered.
• Future Minutes: Input the number of minutes in the future that the recording should continue.
• Camera IDs: Optionally, specify a comma-separated list of camera IDs. If no cameras are specified, all available cameras will be used.

Buttons:

• Start/Extend Event: This function starts a new event or extends an existing one with the specified identifier, past, and future minutes.
• Cancel Event: Cancels the event with the provided identifier.

API Documentation

The web interface also provides examples of how to use the exposed API endpoints with curl. You’ll find this documentation at the bottom of the page, making it easy for users to interact with the service programmatically. The available examples include:

• Start Event
• Cancel Event
• Check Event Status

You can modify these examples to match your specific setup by changing the identifiers, cameras, and time intervals.
