# Release Notes - MVP v1.0.0
**Release Date**: December 9, 2025
**Status**: MVP Complete ✅
---
## Overview
This MVP delivers a complete REST API for Geutebruck GeViScope/GeViSoft cross-switching control. Route cameras to monitors via simple HTTP endpoints with JWT authentication, role-based access control, and comprehensive audit logging.
**What is Cross-Switching?**
Cross-switching is the core operation of routing video from camera inputs to monitor outputs in real-time. This API provides programmatic control over the GeViScope cross-switching matrix.
---
## Key Features
### ✅ Core Functionality
**Cross-Switching Operations**
- Route camera to monitor (`POST /api/v1/crossswitch`)
- Clear monitor (`POST /api/v1/crossswitch/clear`)
- Query routing state (`GET /api/v1/crossswitch/routing`)
- Routing history with pagination (`GET /api/v1/crossswitch/history`)
**Camera Discovery**
- List all cameras with status
- Get camera details
- Search cameras by name/description
- Filter online/PTZ cameras
**Monitor Discovery**
- List all monitors with current camera assignment
- Get monitor details
- Filter available/active monitors
- Get routing state (monitor → camera mapping)
### 🔒 Security
**Authentication**

- Configure firewall rules
- Use secure vault for secrets
- Monitor audit logs for suspicious activity
---
## Known Limitations
1. **SDK Bridge**: Single instance per GeViServer (no load balancing)
2. **Protobuf Generation**: Python gRPC stubs need to be generated from .proto files before SDK Bridge communication works
3. **Default Credentials**: Admin account created with weak password (change immediately)
4. **Rate Limiting**: Not implemented (add in production)
5. **WebSocket**: No real-time updates (polling required)
---

---
## Health Checks
Verify all components are healthy:
```bash
curl http://localhost:8000/health
```
Expected response:
```json
{
"status": "healthy",
"version": "1.0.0",
"environment": "production",
"components": {
"database": {"status": "healthy", "type": "postgresql"},
"redis": {"status": "healthy", "type": "redis"},
"sdk_bridge": {"status": "healthy", "type": "grpc"}
}
}
```
---
## Security Hardening
### 1. Change Default Credentials
**Admin User:**
```python
from passlib.hash import bcrypt
new_password_hash = bcrypt.hash("your-new-secure-password")
# Update in database: UPDATE users SET password_hash = '...' WHERE username = 'admin';
```
### 2. Configure HTTPS
Use reverse proxy (nginx, IIS) with SSL certificate:
```nginx
server {
listen 443 ssl;
server_name api.your-domain.com;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/key.pem;
location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
```
### 3. Firewall Rules
- **API**: Allow port 8000 only from trusted networks
- **SDK Bridge**: Port 50051 localhost only
- **PostgreSQL**: Port 5432 localhost only
- **Redis**: Port 6379 localhost only
### 4. Environment Variables
Store sensitive values in secure vault (Azure Key Vault, AWS Secrets Manager, etc.)
---
## Monitoring
### Logs
**Python API:**
- Location: `logs/api.log`
- Format: JSON (structured logging with structlog)
- Rotation: Configure in production
**SDK Bridge:**
- Location: `logs/sdk-bridge.log`
- Format: Serilog JSON
- Rotation: Daily
### Metrics
- Endpoint: `GET /metrics`
- Consider adding Prometheus exporter for production
### Alerts
Configure alerts for:
- Health check failures
- SDK Bridge disconnections
- Database connection failures
- High error rates in audit logs
---
## Backup & Recovery
### Database Backup
```bash
pg_dump -U geutebruck geutebruck_api > backup.sql
```
Restore:
```bash
psql -U geutebruck geutebruck_api < backup.sql
```
### Configuration Backup
Backup `.env` and `appsettings.json` files securely.
---
## Troubleshooting
### SDK Bridge Connection Failed
1. Check GeViServer is reachable
2. Verify credentials in `.env`
3. Check SDK Bridge logs
4. Test SDK connection manually
### Database Connection Issues
1. Verify PostgreSQL is running
2. Check connection string in `.env`
3. Test connection: `psql -U geutebruck geutebruck_api`
### Redis Connection Issues
1. Verify Redis is running: `redis-cli ping`
2. Check Redis host/port in `.env`
### Authentication Failures
1. Check JWT_SECRET_KEY is set
2. Verify token expiration times
3. Check audit logs for failed login attempts
---
## Scaling
### Horizontal Scaling
- Run multiple API instances behind load balancer
- Share Redis and PostgreSQL instances
- Run single SDK Bridge instance per GeViServer
### Vertical Scaling
- Increase database connection pool size
- Increase Redis max connections
- Allocate more CPU/RAM to API process
---
## Maintenance
### Database Migrations
When updating code with new migrations:
```bash
cd src\api
alembic upgrade head
```
### Dependency Updates
```bash
pip install --upgrade -r requirements.txt
dotnet restore
```

# API Usage Guide
Practical examples for using the Geutebruck Cross-Switching API.
---
## Getting Started
### 1. Login
First, authenticate to get your access token:
**Request:**
```bash
curl -X POST http://localhost:8000/api/v1/auth/login \
-H "Content-Type: application/json" \
-d '{
"username": "admin",
"password": "admin123"
}'
```
**Response:**
```json
{
"access_token": "eyJhbGciOiJIUzI1NiIs...",
"refresh_token": "eyJhbGciOiJIUzI1NiIs...",
"token_type": "bearer",
"expires_in": 3600
}
```
**Save the access token** for subsequent requests.
---
## Common Operations
### Discover Available Cameras
```bash
curl -X GET http://localhost:8000/api/v1/cameras \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
**Response:**
```json
{
"cameras": [
{
"id": 1,
"name": "Entrance Camera",
"status": "online",
"has_ptz": true
},
{
"id": 2,
"name": "Parking Lot Camera",
"status": "online",
"has_ptz": false
}
],
"total": 2
}
```
### Discover Available Monitors
```bash
curl -X GET http://localhost:8000/api/v1/monitors \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
**Response:**
```json
{
"monitors": [
{
"id": 1,
"name": "Control Room Monitor 1",
"status": "idle",
"current_camera_id": null
},
{
"id": 2,
"name": "Control Room Monitor 2",
"status": "active",
"current_camera_id": 5
}
],
"total": 2
}
```
### Find Available (Idle) Monitors
```bash
curl -X GET http://localhost:8000/api/v1/monitors/filter/available \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
Returns only monitors with no camera currently assigned.
---
## Cross-Switching Operations
### Route Camera to Monitor
**⚠️ Requires Operator role or higher**
```bash
curl -X POST http://localhost:8000/api/v1/crossswitch \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"camera_id": 1,
"monitor_id": 1,
"mode": 0
}'
```
**Response:**
```json
{
"success": true,
"message": "Successfully switched camera 1 to monitor 1",
"route": {
"id": "uuid",
"camera_id": 1,
"monitor_id": 1,
"executed_at": "2025-12-09T12:00:00Z",
"executed_by_username": "operator"
}
}
```
### Clear Monitor
**⚠️ Requires Operator role or higher**
```bash
curl -X POST http://localhost:8000/api/v1/crossswitch/clear \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"monitor_id": 1
}'
```
### Get Current Routing State
```bash
curl -X GET http://localhost:8000/api/v1/crossswitch/routing \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
**Response:**
```json
{
"routes": [
{
"camera_id": 1,
"monitor_id": 1,
"executed_at": "2025-12-09T12:00:00Z",
"is_active": true
}
],
"total": 1
}
```
### Get Routing History
```bash
curl -X GET "http://localhost:8000/api/v1/crossswitch/history?limit=10&offset=0" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
**Filter by camera:**
```bash
curl -X GET "http://localhost:8000/api/v1/crossswitch/history?camera_id=1" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
**Filter by monitor:**
```bash
curl -X GET "http://localhost:8000/api/v1/crossswitch/history?monitor_id=1" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
---
## Use Case Examples
### Use Case 1: Quick Camera Check
**Scenario**: Operator wants to quickly view entrance camera on their monitor.
**Steps:**
1. Find available monitor
2. Route entrance camera to that monitor
```bash
# Step 1: Find available monitors
curl -X GET http://localhost:8000/api/v1/monitors/filter/available \
-H "Authorization: Bearer $TOKEN"
# Step 2: Route camera 1 to monitor 1
curl -X POST http://localhost:8000/api/v1/crossswitch \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{"camera_id": 1, "monitor_id": 1}'
```
### Use Case 2: Monitor Rotation
**Scenario**: Automatically rotate through cameras on a monitor.
**Script (PowerShell):**
```powershell
$token = "YOUR_ACCESS_TOKEN"
$monitor_id = 1
$cameras = @(1, 2, 3, 4) # Camera IDs to rotate
foreach ($camera_id in $cameras) {
# Switch camera
Invoke-RestMethod -Uri "http://localhost:8000/api/v1/crossswitch" `
-Method POST `
-Headers @{ "Authorization" = "Bearer $token" } `
-ContentType "application/json" `
-Body (@{ camera_id = $camera_id; monitor_id = $monitor_id } | ConvertTo-Json)
# Wait 10 seconds
Start-Sleep -Seconds 10
}
```
### Use Case 3: Incident Response
**Scenario**: Security incident detected, switch multiple cameras to control room monitors.
```bash
# Cameras 1-4 to monitors 1-4
for i in {1..4}; do
curl -X POST http://localhost:8000/api/v1/crossswitch \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d "{\"camera_id\": $i, \"monitor_id\": $i}"
done
```
### Use Case 4: Audit Trail Review
**Scenario**: Review who accessed which cameras today.
```bash
# Get routing history for today
curl -X GET "http://localhost:8000/api/v1/crossswitch/history?limit=100" \
-H "Authorization: Bearer $TOKEN" \
| jq '.history[] | select(.executed_at | startswith("2025-12-09"))'
```

return response.json()
def crossswitch(self, camera_id, monitor_id, mode=0):
"""Execute cross-switch"""
response = requests.post(
f"{self.base_url}/api/v1/crossswitch",
headers=self._headers(),
json={
"camera_id": camera_id,

def get_routing_state(self):
"""Get current routing state"""
response = requests.get(
f"{self.base_url}/api/v1/crossswitch/routing",
headers=self._headers()
)
return response.json()
# Usage Example
api = GeutebruckAPI()
# List cameras
cameras = api.list_cameras()
print(f"Found {cameras['total']} cameras")
# Route camera 1 to monitor 1
result = api.crossswitch(camera_id=1, monitor_id=1)
print(f"Cross-switch: {result['message']}")
# Get routing state
routing = api.get_routing_state()
print(f"Active routes: {routing['total']}")
```

## C# Client Example
```csharp
using System;
using System.Net.Http;
using System.Net.Http.Json;
using System.Threading.Tasks;
public class GeutebruckApiClient
{
private readonly HttpClient _client;
private string _accessToken;
public GeutebruckApiClient(string baseUrl = "http://localhost:8000")
{
_client = new HttpClient { BaseAddress = new Uri(baseUrl) };
}
public async Task LoginAsync(string username, string password)
{
var response = await _client.PostAsJsonAsync("/api/v1/auth/login", new
{
username,
password
});
response.EnsureSuccessStatusCode();
var result = await response.Content.ReadFromJsonAsync<LoginResponse>();
_accessToken = result.AccessToken;
_client.DefaultRequestHeaders.Authorization =
new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", _accessToken);
}
public async Task<CameraListResponse> ListCamerasAsync()
{
var response = await _client.GetAsync("/api/v1/cameras");
response.EnsureSuccessStatusCode();
return await response.Content.ReadFromJsonAsync<CameraListResponse>();
}
public async Task<CrossSwitchResponse> ExecuteCrossSwitchAsync(int cameraId, int monitorId, int mode = 0)
{
var response = await _client.PostAsJsonAsync("/api/v1/crossswitch", new
{
camera_id = cameraId,
monitor_id = monitorId,
mode
});
response.EnsureSuccessStatusCode();
return await response.Content.ReadFromJsonAsync<CrossSwitchResponse>();
}
}
// Usage
var api = new GeutebruckApiClient();
await api.LoginAsync("admin", "admin123");
var cameras = await api.ListCamerasAsync();
Console.WriteLine($"Found {cameras.Total} cameras");
var result = await api.ExecuteCrossSwitchAsync(cameraId: 1, monitorId: 1);
Console.WriteLine($"Cross-switch: {result.Message}");
```

## Testing with Postman
1. **Import Collection**: Import the OpenAPI spec from http://localhost:8000/openapi.json
2. **Set Environment Variable**: Create `access_token` variable
3. **Login**: Run POST /api/v1/auth/login, save token to environment
4. **Test Endpoints**: All subsequent requests will use the token automatically
---
## Troubleshooting
### 401 Unauthorized
**Problem**: Token expired or invalid.
**Solution**: Re-authenticate:
```bash
# Get new token
curl -X POST http://localhost:8000/api/v1/auth/login \
-d '{"username":"admin","password":"admin123"}'
```
### 403 Forbidden
**Problem**: User role insufficient (e.g., Viewer trying to execute cross-switch).
**Solution**: Use account with Operator or Administrator role.
### 404 Not Found
**Problem**: Camera or monitor ID doesn't exist.
**Solution**: List cameras/monitors to find valid IDs.
### 500 Internal Server Error
**Problem**: SDK Bridge communication failure or database error.
**Solution**:
1. Check health endpoint: `/health`
2. Verify SDK Bridge is running
3. Check API logs
---
## Best Practices
1. **Always check health before operations**
2. **Cache camera/monitor lists** (refreshed every 60s)
3. **Handle 401 errors** by re-authenticating
4. **Use refresh tokens** to extend sessions
5. **Log all cross-switch operations** to external system
6. **Implement retry logic** for transient failures
7. **Monitor audit logs** for security events
