Configuration System

Configuration Files

All configuration is stored as JSON files, managed centrally on the AppServer and synced to each keyboard.

appsettings.json (Main)

{
    "UseSoftwareRendering": true,
    "AppServerConfiguration": {
        "Uri": "https://copilot.test.d6.colsys.cz",

    }
}

Setting	Value	Purpose
`UseSoftwareRendering`	`true`	Forces WPF software rendering (no GPU) for LattePanda

            "Allowed": true,
            "Speeds": [1, 2, 5, 15, 30, 100, 250]
        },
        "AlarmHistoryOptions": {
            "CameraIdExtractionRegex": "^\\D*(?<CameraId>\\d{6})\\D*$",
            "DefaultSearchInterval": "30.00:00:00"
        }
    }
}

`PlaybackOptions.Speeds`	Shuttle playback speeds (1x to 250x)
`AllowPrepositionsInterval`	Valid preposition range (10-99)

appsettings-camera-servers.json

{
    "CameraServerConfig": {
        "CameraServers": [
            {
                "IpAddress": "192.168.102.20",
                "UserName": "sysadmin",
                "Password": "masterkey",
                "CameraServerType": "GCore"
            },
            {
                "IpAddress": "192.168.102.186",
                "UserName": "sysadmin",
                "Password": "masterkey",
                "CameraServerType": "GeviScope"
            }
        ]
    }
}

Supported server types: GeViScope, GCore, GeViSoft

appsettings-monitor-wall.json (Topology)

Defines the physical monitor wall layout:

graph TD
    subgraph "Wall (WallId: 1, Name: HDŘÚ TSK/DIC)"
        subgraph "Segment 1 (4 rows × 8 cols)"
            M1["Monitor #01<br/>2×2 span<br/>VM: 151,152,153,154"]
            M2["Monitor #02<br/>2×2 span<br/>VM: 155,156,157,158"]
            M3["Monitor #03"]
            M4["Monitor #04"]
            M5["Monitor #05<br/>...etc"]
        end
    end

Hierarchy:

Wall
  └── Segment (grid: RowCount × ColumnCount)
        └── Monitor (physical screen, positioned at Row/Col with RowSpan/ColSpan)
              └── VirtualMonitor (individual video feed, positioned within monitor grid)

A single physical monitor can display multiple virtual monitors (e.g., 2×2 quad view). Each VirtualMonitor has a unique VirtualMonitorId that maps to a ViewerId in the camera server.

appsettings-function-buttons.json

Maps F1-F7 and Home keys to actions per wall:

{
    "FunctionButtonsConfig": {
        "FunctionButtons": [
            {
                "WallId": 1,
                "Buttons": [
                    {
                        "Button": "F1",
                        "Actions": [
                            { "ViewerId": 1001, "ActionType": "CrossSwitch", "SourceId": 501111 },
                            { "ViewerId": 1002, "ActionType": "CrossSwitch", "SourceId": 502345 }
                        ]
                    },
                    {
                        "Button": "F4",
                        "Actions": [
                            { "ViewerId": 1001, "ActionType": "SequenceStart", "SourceId": 258 }
                        ]
                    }
                ]
            }
        ]
    }
}

Action types: CrossSwitch (switch camera to viewer), SequenceStart (start camera cycling)

appsettings-sequences.json

{
    "SequencesConfig": {
        "Sequences": [
            {
