# go-onvif Architecture & Design
## Overview
go-onvif is a modern, performant Go library for communicating with ONVIF-compliant IP cameras and devices. It provides a clean, type-safe API with comprehensive support for device management, media streaming, PTZ control, and imaging settings.
## Architecture
### Core Components
```
┌─────────────────────────────────────────────────────────────┐
│ Client Layer │
│ - onvif.Client: Main entry point │
│ - Context-aware operations │
│ - Connection pooling │
│ - Credential management │
└─────────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────────┐
│ Service Layer │
│ - Device Service (device.go) │
│ - Media Service (media.go) │
│ - PTZ Service (ptz.go) │
│ - Imaging Service (imaging.go) │
└─────────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────────┐
│ Transport Layer │
│ - SOAP Client (soap/soap.go) │
│ - WS-Security Authentication │
│ - XML Marshaling/Unmarshaling │
└─────────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────────┐
│ Network Layer │
│ - HTTP Client with connection pooling │
│ - TLS support │
│ - Timeout management │
└─────────────────────────────────────────────────────────────┘
```
### Discovery Component
```
┌─────────────────────────────────────────────────────────────┐
│ WS-Discovery Service │
│ - Multicast UDP probe │
│ - Device enumeration │
│ - Service endpoint discovery │
└─────────────────────────────────────────────────────────────┘
```
## Key Design Decisions
### 1. Context-First Design
All network operations accept `context.Context` as the first parameter, enabling:
- Request cancellation
- Timeout control
- Request tracing
- Graceful shutdown
```go
ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()
info, err := client.GetDeviceInformation(ctx)
```
### 2. Functional Options Pattern
Client configuration uses functional options for flexibility:
```go
client, err := onvif.NewClient(
endpoint,
onvif.WithCredentials(username, password),
onvif.WithTimeout(30*time.Second),
onvif.WithHTTPClient(customClient),
)
```
### 3. Type Safety
Strong typing throughout the API with comprehensive struct definitions:
- Clear data structures for all ONVIF types
- Type-safe service methods
- Compile-time error detection
### 4. Error Handling
Multiple error handling strategies:
- Sentinel errors for common cases (`ErrServiceNotSupported`, `ErrAuthenticationFailed`)
- Typed `ONVIFError` for SOAP faults
- Wrapped errors with context
```go
if err := client.ContinuousMove(ctx, profileToken, velocity, nil); err != nil {
if errors.Is(err, onvif.ErrServiceNotSupported) {
// Handle missing PTZ support
} else if onvif.IsONVIFError(err) {
// Handle SOAP fault
}
}
```
### 5. Concurrency Safety
Thread-safe operations with proper locking:
- Mutex-protected credential management
- Safe concurrent API calls
- Connection pool management
### 6. Performance Optimization
Multiple performance optimizations:
- HTTP connection pooling
- Reusable HTTP client
- Efficient XML marshaling
- Minimal allocations in hot paths
## Service Implementations
### Device Service
Provides device management functionality:
- Device information retrieval
- Capability discovery
- System operations (reboot, date/time)
- Service endpoint enumeration
### Media Service
Handles media profiles and streaming:
- Profile management
- Stream URI generation (RTSP/HTTP)
- Snapshot URI retrieval
- Encoder configuration
### PTZ Service
Controls pan-tilt-zoom operations:
- Continuous movement
- Absolute positioning
- Relative positioning
- Preset management
- Status monitoring
### Imaging Service
Manages image settings:
- Brightness, contrast, saturation
- Exposure control
- Focus management
- White balance
- Wide dynamic range (WDR)
## Security
### WS-Security Implementation
Authentication uses WS-Security UsernameToken with password digest:
1. Generate random nonce (16 bytes)
2. Get current UTC timestamp
3. Calculate digest: `Base64(SHA1(nonce + created + password))`
4. Include in SOAP header
```xml
<Security>
<UsernameToken>
<Username>admin</Username>
<Password Type="...#PasswordDigest">digest</Password>
<Nonce EncodingType="...#Base64Binary">nonce</Nonce>
<Created>2024-01-01T12:00:00Z</Created>
</UsernameToken>
</Security>
```
### Transport Security
- Supports HTTP and HTTPS
- Configurable TLS settings via custom HTTP client
- Certificate validation control
## Discovery Protocol
WS-Discovery implementation:
1. Send multicast probe to `239.255.255.250:3702`
2. Listen for probe matches
3. Parse device information from responses
4. Extract service endpoints (XAddrs)
5. Deduplicate devices by endpoint reference
## SOAP Message Flow
```
Client Request
↓
Build SOAP Envelope
↓
Add WS-Security Header (if authenticated)
↓
Marshal to XML
↓
HTTP POST
↓
Receive Response
↓
Parse SOAP Envelope
↓
Check for Fault
↓
Unmarshal Response Data
↓
Return to Caller
```
## Testing Strategy
### Unit Tests
- Client initialization and configuration
- Error handling
- Type validation
- Option application
### Integration Tests (with mock servers)
- SOAP message formatting
- Response parsing
- Error handling
### Real Device Tests
- Full service workflows
- PTZ operations
- Media streaming
- Discovery
## Performance Characteristics
### Benchmarks (typical)
- Client creation: ~100 µs
- SOAP call: ~10-50 ms (network dependent)
- Discovery: ~1-5 seconds
- Memory usage: ~1-5 MB per client
### Scalability
- Supports hundreds of concurrent clients
- Connection pooling reduces overhead
- Minimal memory footprint per device
## Future Enhancements
### Planned Features
- Event service (event subscription, pull-point)
- Analytics service (rule engine, motion detection)
- Recording service (recording management)
- Replay service (playback control)
- Advanced security (X.509 certificates)
### Optimizations
- Response caching for static data
- Batch operations support
- Streaming data handling
- WebSocket support for events
## Best Practices
### Client Lifecycle
```go
// Create client once
client, err := onvif.NewClient(endpoint, options...)
if err != nil {
return err
}
// Initialize to discover services
if err := client.Initialize(ctx); err != nil {
return err
}
// Reuse client for multiple operations
// ...
// No explicit cleanup needed (HTTP client manages connections)
```
### Error Handling
```go
info, err := client.GetDeviceInformation(ctx)
if err != nil {
// Check for specific errors
if errors.Is(err, context.DeadlineExceeded) {
// Handle timeout
}
return fmt.Errorf("failed to get device info: %w", err)
}
```
### Resource Management
```go
// Use contexts with timeouts
ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()
// Operations automatically respect context cancellation
result, err := client.Operation(ctx, ...)
```
## Dependencies
Minimal external dependencies:
- `golang.org/x/net`: HTTP/2 support and IDNA
- `golang.org/x/text`: Character encoding
- Go standard library: Everything else
## Compliance
- **ONVIF Core Specification**: ✓
- **ONVIF Profile S** (Streaming): ✓
- **ONVIF Profile T** (Advanced Streaming): Partial
- **ONVIF Profile G** (Recording): Planned
- **WS-Security**: ✓ (UsernameToken)
- **WS-Discovery**: ✓
## Conclusion
go-onvif provides a modern, performant, and easy-to-use Go library for ONVIF camera integration. Its architecture prioritizes:
- Developer experience (simple, intuitive API)
- Type safety (compile-time error detection)
- Performance (connection pooling, efficient operations)
- Reliability (comprehensive error handling)
- Standards compliance (ONVIF specifications)

# Camera-Specific Integration Tests
This directory contains integration tests for specific ONVIF camera models based on real-world testing.
## Bosch FLEXIDOME indoor 5100i IR Tests
The `bosch_flexidome_test.go` file contains comprehensive tests verified against a real Bosch FLEXIDOME indoor 5100i IR camera running firmware 8.71.0066.
### Running the Tests
Set the following environment variables with your camera credentials:
```bash
export ONVIF_TEST_ENDPOINT="http://192.168.1.201/onvif/device_service"
export ONVIF_TEST_USERNAME="service"
export ONVIF_TEST_PASSWORD="Service.1234"
```
Then run the tests:
```bash
# Run all tests
go test -v ./... -run TestBoschFLEXIDOMEIndoor5100iIR
# Run specific test
go test -v -run TestBoschFLEXIDOMEIndoor5100iIR_GetDeviceInformation
# Run all tests with race detection
go test -v -race -run TestBoschFLEXIDOMEIndoor5100iIR
# Run benchmarks
go test -v -bench=BenchmarkBoschFLEXIDOMEIndoor5100iIR -benchmem
# Run full workflow test
go test -v -run TestBoschFLEXIDOMEIndoor5100iIR_FullWorkflow
```
### Test Coverage
The tests cover the following ONVIF operations:
- ✅ **GetDeviceInformation** - Device identification and firmware info
- ✅ **GetSystemDateAndTime** - System time retrieval

### Test Without Camera
If environment variables are not set, tests will be automatically skipped:
```bash
go test -v ./...
# Output: SKIP: Skipping test: ONVIF camera credentials not set
```
### Performance Benchmarks
The test suite includes benchmarks for critical operations:
- `BenchmarkBoschFLEXIDOMEIndoor5100iIR_GetDeviceInformation` - Device info retrieval performance
- `BenchmarkBoschFLEXIDOMEIndoor5100iIR_GetStreamURI` - Stream URI retrieval performance
### Adding Tests for Other Camera Models
To add tests for a new camera model:
1. Create a new test file: `<manufacturer>_<model>_test.go`
2. Follow the same pattern as `bosch_flexidome_test.go`
3. Update environment variable names to be model-specific if needed
4. Document expected values and behaviors for the specific model
5. Add README entry with camera-specific details
Example:
```go
// hikvision_ds2cd2xxx_test.go
func TestHikvisionDS2CD_GetDeviceInformation(t *testing.T) {
// Test implementation
}
```
### Continuous Integration
These tests can be integrated into CI/CD pipelines using secrets management:
```yaml
# GitHub Actions example
- name: Run Camera Integration Tests
env:
ONVIF_TEST_ENDPOINT: ${{ secrets.ONVIF_ENDPOINT }}
ONVIF_TEST_USERNAME: ${{ secrets.ONVIF_USERNAME }}
ONVIF_TEST_PASSWORD: ${{ secrets.ONVIF_PASSWORD }}
run: go test -v -run TestBoschFLEXIDOMEIndoor5100iIR
```
### Troubleshooting
**Tests fail with "connection refused":**
- Verify camera IP address and network connectivity
- Check firewall settings
- Ensure camera is powered on
**Tests fail with authentication errors:**
- Verify username and password are correct
- Check if camera requires digest authentication
- Ensure user has appropriate permissions
**Tests fail with unexpected values:**
- Camera firmware may have been updated
- Camera settings may have been changed
- Update expected values in tests to match current configuration
### Notes
- These tests require a physical camera or camera simulator
- Tests modify NO camera settings (read-only operations)
- Some tests may take several seconds due to network communication
- Camera responses may vary based on firmware version and configuration

# ONVIF Debugging Solution
## Problem
The diagnostic utility (`onvif-diagnostics`) logs only parsed JSON results. When XML parsing fails or responses are unexpected, you can't see the raw SOAP XML to debug the issue.
## Solution
The `onvif-diagnostics` utility now includes built-in XML capture functionality via the `-capture-xml` flag. This captures raw SOAP request/response XML and creates a compressed tar.gz archive.
## What Changed
### 1. Enhanced SOAP Client (`soap/soap.go`)
Added debug logging capability:
```go
type Client struct {
httpClient *http.Client
username string
password string
debug bool // NEW
logger func(format string, args ...interface{}) // NEW
}
// New methods:
func (c *Client) SetDebug(enabled bool, logger func(format string, args ...interface{}))
func (c *Client) logDebug(format string, args ...interface{})
```
The SOAP client now logs requests/responses when debug mode is enabled.
### 2. Integrated XML Capture in `onvif-diagnostics`
Location: `cmd/onvif-diagnostics/main.go`
Features:
- Single command for both diagnostic report and XML capture
- `-capture-xml` flag enables raw SOAP traffic capture
- Creates compressed tar.gz archive with camera identification
- Archive naming: `Manufacturer_Model_Firmware_xmlcapture_timestamp.tar.gz`
- Saves to `camera-logs/` directory (same as diagnostic report)
- Automatic cleanup of temporary files
## Usage
### Quick Start
```bash
# Build the utility
go build -o onvif-diagnostics ./cmd/onvif-diagnostics/
# Run with XML capture enabled
./onvif-diagnostics \
-endpoint "http://192.168.1.164/onvif/device_service" \
-username "admin" \
-password "password" \
-capture-xml \
-verbose
```
This creates two files:
- `Manufacturer_Model_Firmware_timestamp.json` - Diagnostic report
- `Manufacturer_Model_Firmware_xmlcapture_timestamp.tar.gz` - Raw SOAP XML archive
### Without XML Capture (Faster)
```bash
# Just diagnostic report
./onvif-diagnostics \
-endpoint "http://192.168.1.164/onvif/device_service" \
-username "admin" \
-password "password" \
-verbose
```
### Extract and Analyze XML
```bash
# Extract the archive
tar -xzf camera-logs/Camera_Model_xmlcapture_timestamp.tar.gz -C /tmp/xml-debug
# View files (now with operation names)
ls /tmp/xml-debug/
# capture_001_GetDeviceInformation.json
# capture_001_GetDeviceInformation_request.xml
# capture_001_GetDeviceInformation_response.xml
# capture_002_GetSystemDateAndTime.json
# ...
```
## Workflow
### 1. Run Diagnostic with XML Capture
```bash
./onvif-diagnostics \
-endpoint "http://camera-ip/onvif/device_service" \
-username "user" \
-password "pass" \
-capture-xml \
-verbose
```
This generates both:
- JSON diagnostic report
- tar.gz XML capture archive
### 2. Review Diagnostic Report
Check the JSON file for errors:
```bash
cat camera-logs/Camera_Model_Firmware_timestamp.json | jq '.errors'
```
### 3. Analyze Raw XML (if needed)
Extract and inspect the XML archive:
```bash
tar -xzf camera-logs/Camera_Model_xmlcapture_timestamp.tar.gz -C /tmp/xml-debug
```
### 3. Analyze Raw XML
```bash
# Extract the archive
tar -xzf camera-logs/Camera_Model_xmlcapture_timestamp.tar.gz -C /tmp/xml-debug
# View specific operation (now easier to find)
cat /tmp/xml-debug/capture_*_GetCapabilities_response.xml
# Search for errors
grep "Fault" /tmp/xml-debug/capture_*_response.xml
# Pretty-print (XML is already formatted with indentation)
cat /tmp/xml-debug/capture_001_GetDeviceInformation_response.xml
```
## Example: Debugging AXIS Q3626-VE Localhost Issue
### Problem (from diagnostic report)
```json
{
"operation": "GetProfiles",
"error": "Post \"http://127.0.0.1/onvif/services\": EOF"
}
```
### Capture XML
```bash
### Capture XML
```bash
./onvif-diagnostics \
-endpoint "http://192.168.1.164/onvif/device_service" \
-username "admin" \
-password "password" \
-capture-xml \
-verbose
```
Result:
- `camera-logs/AXIS_Q3626-VE_12.6.104_20251110-120000.json`
- `camera-logs/AXIS_Q3626-VE_12.6.104_xmlcapture_20251110-120000.tar.gz`
```
Result: `camera-logs/AXIS_Q3626-VE_12.6.104_xmlcapture_20251110-120000.tar.gz`
### Analyze Response
```bash
tar -xzf camera-logs/AXIS_Q3626-VE_12.6.104_xmlcapture_20251110-120000.tar.gz
cat capture_*_GetCapabilities_response.xml | grep XAddr
```
Shows:
```xml
<Media>
<XAddr>http://127.0.0.1/onvif/services</XAddr>
</Media>
```
### Root Cause
Camera returns `127.0.0.1` instead of actual IP `192.168.1.164`, causing client to connect to localhost.
### Solution Required
Client needs to rewrite localhost addresses:
```go
if strings.Contains(xAddr, "127.0.0.1") || strings.Contains(xAddr, "localhost") {
// Replace with actual camera IP from original endpoint
}
```
## Example: Debugging Bosch Panoramic "Incomplete Configuration"
### Problem (from diagnostic report)
```json
{
"operation": "GetStreamURI[9]",
"error": "ter:IncompleteConfiguration - Configuration not complete"
}
```
### Capture XML
```bash
### Capture XML
```bash
./onvif-diagnostics \
-endpoint "http://192.168.2.24/onvif/device_service" \
-username "service" \
-password "Service.1234" \
-capture-xml \
-verbose
```
Result:
- `camera-logs/Bosch_FLEXIDOME_panoramic_5100i_9.00.0210_20251110.json`
- `camera-logs/Bosch_FLEXIDOME_panoramic_5100i_9.00.0210_xmlcapture_20251110.tar.gz`
```
### Analyze Response
```bash
tar -xzf camera-logs/Bosch_FLEXIDOME_panoramic_5100i_*_xmlcapture_*.tar.gz
# Look for GetStreamUri operation (easy to find by name)
cat capture_*_GetStreamUri_response.xml
```
Result:
```xml
<SOAP-ENV:Fault>
<SOAP-ENV:Code>
<SOAP-ENV:Subcode>
<SOAP-ENV:Value>ter:IncompleteConfiguration</SOAP-ENV:Value>
</SOAP-ENV:Subcode>
</SOAP-ENV:Code>
<SOAP-ENV:Reason>
<SOAP-ENV:Text>Configuration not complete</SOAP-ENV:Text>
</SOAP-ENV:Reason>
</SOAP-ENV:Fault>
```
### Root Cause
Profile 9 has `VideoEncoderConfiguration: null` in the profiles response. Can't get stream URI for profile without video encoder.
### Solution
Skip GetStreamURI for profiles without VideoEncoderConfiguration:
```go
if profile.VideoEncoderConfiguration == nil {
// Skip - this is audio-only or metadata-only profile
continue
}
```
## Files Created
### SOAP Client Enhancement
- `soap/soap.go` - Added debug logging capability
### Diagnostic Utility Enhancement
- `cmd/onvif-diagnostics/main.go` - Added XML capture functionality with `-capture-xml` flag
## Output Organization
All debugging files are saved to the same `camera-logs/` directory:
```
camera-logs/
├── Bosch_FLEXIDOME_indoor_5100i_IR_8.71.0066_20251107-193656.json # Diagnostic report
├── Bosch_FLEXIDOME_indoor_5100i_IR_8.71.0066_xmlcapture_20251110.tar.gz # XML capture archive
├── AXIS_Q3626-VE_12.6.104_20251108-212157.json
├── AXIS_Q3626-VE_12.6.104_xmlcapture_20251108-213000.tar.gz
└── Bosch_FLEXIDOME_panoramic_5100i_9.00.0210_20251107-195636.json
```
### Archive Contents
Each tar.gz archive contains the captured XML files with descriptive operation names:
```bash
$ tar -tzf camera-logs/Bosch_FLEXIDOME_indoor_5100i_IR_*_xmlcapture_*.tar.gz
capture_001_GetDeviceInformation.json
capture_001_GetDeviceInformation_request.xml
capture_001_GetDeviceInformation_response.xml
capture_002_GetSystemDateAndTime.json
capture_002_GetSystemDateAndTime_request.xml
capture_002_GetSystemDateAndTime_response.xml
capture_003_GetCapabilities.json
capture_003_GetCapabilities_request.xml
capture_003_GetCapabilities_response.xml
...
```
Each file is named with both a sequence number and the SOAP operation name for easy identification.
## Benefits
1. **Complete Visibility**: See exact SOAP XML sent/received
2. **Namespace Debugging**: Identify namespace mismatches
3. **Fault Analysis**: See detailed SOAP fault information
4. **Comparison**: Compare working vs failing cameras
5. **Easy Sharing**: Compressed archives (< 10KB) easy to share via email
6. **Organized**: All camera logs in one directory with consistent naming
7. **Privacy**: Review and sanitize XML before sharing archives
## Next Steps
When you encounter errors in the diagnostic report:
1. ✅ Run `onvif-diagnostics` to identify which operations fail
2. ✅ Re-run with `-capture-xml` flag to capture raw XML
3. ✅ Extract and analyze the tar.gz archive
4. ✅ Share both files (JSON report + tar.gz archive) for debugging assistance
