# SurveillanceClient

.NET 10 host for driving the vendor `RSNet.dll` (32-bit) to download
recorded video from a surveillance NVR/DVR.

## Layout

- `src/SurveillanceClient.Core` — class library that wraps the `RSNet.dll`
  native exports behind a service interface (`IRsNetClient`).
- `src/SurveillanceClient.Cli` — console host used for iterative,
  manual testing of the Core library against a real device.

## Platform

`RSNet.dll` is a 32-bit Visual Studio DLL using `__stdcall`. Every
project in this solution targets `x86` via `Directory.Build.props`.

## Running

The vendor DLL and its dependencies live in
`i:\Apps\Surveillance_client`. The CLI sets that directory as the
native DLL search path at startup so the DLL and its `.ini` config
are found.

## Credentials

Credentials are **never committed**. Configure them via .NET user
secrets (recommended) or a `appsettings.Local.json` file (ignored by
`.gitignore`).

### User secrets (recommended)

```powershell
cd src/SurveillanceClient.Cli
dotnet user-secrets set "Device:Host" "192.168.100.92"
dotnet user-secrets set "Device:Port" "9000"
dotnet user-secrets set "Device:Username" "admin"
dotnet user-secrets set "Device:Password" "your-password-here"
```

### appsettings.Local.json (alternative)

Create `src/SurveillanceClient.Cli/appsettings.Local.json`:

```json
{
  "Device": {
    "Host": "192.168.100.92",
    "Port": 9000,
    "Username": "admin",
    "Password": "your-password-here"
  }
}
```

## Build / Run

```powershell
cd SurveillanceClient
dotnet build
dotnet run --project src/SurveillanceClient.Cli
```
