## Technical Requirements and Best Practices
The URZ recommends several best practices to ensure stability and quality:

### Hardware and Environment
- **Devices**: Use a modern PC, laptop, or mobile device with a webcam.
- **Audio**: Use headsets or headphones to prevent acoustic feedback.
- **Visuals**: Ensure sufficient lighting (avoiding backlight).
- **Room**: Use a low-noise, sound-dampened room.

### Connectivity and Workflow
- **Connectivity**: Use a wired Ethernet connection instead of WLAN for better stability.
- **Screen Management**: Use a second screen for presentations to keep participants and content in view.
- **Preparation**: Conduct test sessions prior to the actual conference.

### Group Settings
- **Equipment**: Use conference microphones and wide-angle cameras to capture all on-site participants.
- **Viewing**: Use projectors for shared viewing.

## Support
Technical support is provided by the [[universitatsrechenzentrum-urz]] via:
