Documentation**: Visit [pkg.go.dev](https://pkg.go.dev/github.com/0x524A/go-onvif) +3. **Review Architecture**: See [ARCHITECTURE.md](ARCHITECTURE.md) for design details +4. **Check Issues**: Look at [GitHub Issues](https://github.com/0x524A/go-onvif/issues) for known issues + +## Common Patterns + +### Error Handling + +```go +info, err := client.GetDeviceInformation(ctx) +if err != nil { + if errors.Is(err, context.DeadlineExceeded) { + // Handle timeout + } else if onvif.IsONVIFError(err) { + // Handle SOAP fault + } else { + // Handle other errors + } + return err +} +``` + +### Context with Timeout + +```go +ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second) +defer cancel() + +result, err := client.SomeOperation(ctx) +``` + +### Checking Service Support + +```go +status, err := client.GetStatus(ctx, profileToken) +if errors.Is(err, onvif.ErrServiceNotSupported) { + fmt.Println("PTZ not supported on this camera") +} else if err != nil { + return err +} +``` + +## Tips & Tricks + +1. **Always Initialize**: Call `client.Initialize(ctx)` before using service-specific methods +2. **Use Timeouts**: Always use contexts with timeouts for network operations +3. **Reuse Clients**: Create one client per camera and reuse it +4. **Check Capabilities**: Use `GetCapabilities()` to check what the camera supports +5. **Handle Errors**: Check for `ErrServiceNotSupported` when using optional services + +## Troubleshooting + +### Camera Not Found During Discovery +- Check network connectivity +- Ensure camera is on the same subnet +- Verify ONVIF is enabled on the camera +- Check firewall settings (UDP port 3702) + +### Authentication Failed +- Verify username and password +- Check if camera requires admin privileges +- Some cameras need authentication enabled + +### Connection Timeout +- Increase timeout duration +- Check network latency +- Verify endpoint URL is correct +- Test with ping/curl first + +### Service Not Supported +- Check camera capabilities with `GetCapabilities()` +- Update camera firmware if needed +- Some features require specific ONVIF profiles + +## Additional Resources + +- [ONVIF Official
