+# GeViScope SDK Analysis
+
+## Overview
+
+GeViScope is Geutebruck's DVR (Digital Video Recorder) system that handles:
+- Video recording and playback
+- Camera management (PTZ control)
+- Event handling
+- Action-based communication
+
+## SDK Components
+
+### Native Win32 DLLs (32-bit)
+| DLL | Purpose |
+|-----|---------|
+| GscDBI.dll | Database interface - connection, registry, data access |
+| GscActions.dll | PLC (Process Logic Control) - action/event handling |
+| GscMediaPlayer.dll | Video display and playback |
+| GscHelper.dll | Helper functions |
+
+### .NET Wrapper DLLs (.NET 4.0)
+| DLL | Purpose |
+|-----|---------|
+| GscExceptionsNET_4_0.dll | Exception handling |
+| GscDBINET_4_0.dll | Database interface wrapper |
+| GscActionsNET_4_0.dll | Actions/PLC wrapper |
+| GscMediaPlayerNET_4_0.dll | Media player wrapper |
+
+## Key Namespaces
+
+```csharp
+using GEUTEBRUECK.GeViScope.Wrapper.DBI;
+using GEUTEBRUECK.GeViScope.Wrapper.Actions;
+using GEUTEBRUECK.GeViScope.Wrapper.Actions.SystemActions;
+using GEUTEBRUECK.GeViScope.Wrapper.Actions.DigitalContactsActions;
+using GEUTEBRUECK.GeViScope.Wrapper.Actions.ActionDispatcher;
+using GEUTEBRUECK.GeViScope.Wrapper.MediaPlayer;
+```
+
+## Connection Flow
+
+1. Create GscServer instance
+2. Encode password: `DBIHelperFunctions.EncodePassword(password)`
+3. Set connection parameters: `GscServerConnectParams`
+4. Connect: `GscServer.Connect()`
+5. Create PLC: `GscServer.CreatePLC()`
+6. Subscribe to actions/events
+7. Register action dispatcher callbacks
+
+## Key Classes
+
+### GscServer
+- Main connection class
+- Methods: `Connect()`, `Disconnect()`, `CreatePLC()`, `CreateRegistry()`
+
+### GscPLCWrapper
+- Process Logic Control for actions/events
+- Methods: `OpenPushCallback()`, `SendAction()`, `StartEvent()`, `StopEvent()`
+- Methods: `SubscribeActionsAll()`, `SubscribeEventsAll()`
+
+### GscActionDispatcher
+- Dispatches received actions to handlers
+- Events: `OnCustomAction`, `OnDigitalInput`, `OnCrossSwitch`, etc.
+
+### GscViewer
+- Video viewer for live/recorded media
+- Methods: `ConnectDB()`, `SetPlayMode()`, `Refresh()`
+
+## Action Categories
+
+1. **ATM/ACS** - Banking/Access control
+2. **Audio Control** - ABC (Audio Back Channel)
+3. **Backup Actions** - Auto/event backups
+4. **Camera Control** - PTZ, focus, iris, presets
+5. **Digital Contacts** - Digital I/O
+6. **Switch Control** - CrossSwitch (video routing)
+7. **Viewer Actions** - Remote control GSCView
+8. **System Actions** - Login, shutdown, events
+
+## Sample Actions
+
+```csharp
+// Custom Action
+GscAction action = new GscAct_CustomAction(1, "Hello world!");
+plc.SendAction(action);
+
+// CrossSwitch
+GscAction crossSwitch = GscAction.Decode("CrossSwitch(1, 2, 0)");
+plc.SendAction(crossSwitch);
+
+// PTZ Control
+GscAction ptzAction = GscAction.Decode("CameraPanLeft(1, 50)");
+plc.SendAction(ptzAction);
+```
+
+## TACI - Telnet Action Command Interface
+
+Alternative method for sending/receiving actions via Telnet (ASCII format):
+- Default port: 12007
+- Requires GscTelnetActionCommandInterface.dll plugin
+- Format: Action text commands like `CustomAction(1,"HelloWorld")`
+
+## Default Credentials
+
+- Username: `sysadmin`
+- Password: `masterkey`
+
+## Demo Mode
+
+- Full functionality for 2 hours
+- After timeout, restart GeViScope server for another 2 hours
+
+## Integration Approach
+
+Similar to GeViServer, create a C# Bridge service that:
+1. References the .NET wrapper DLLs
+2. Exposes REST API endpoints
+3. Handles connection lifecycle
+4. Forwards actions/events
+
+### Proposed Endpoints
+
+```
+POST /geviscope/connect
+POST /geviscope/disconnect
+GET  /geviscope/status
+GET  /geviscope/channels
+POST /geviscope/action
+POST /geviscope/event/start
+POST /geviscope/event/stop
+POST /geviscope/camera/ptz
+```
