UZUNER Broadcast Recording System: Setup Guide and Best Practices

Troubleshooting Common Issues with the UZUNER Broadcast Recording System

Check inputs: Verify mic/line and video sources are connected and powered.
Input selection: Confirm the recorder’s input channels are assigned to the right sources in Settings → Inputs.
Level & gain: Increase input gain/trim; confirm audio isn’t muted.
File format/codec: Ensure encoder settings (sample rate, bitrate, codec) match source capability.
Test loopback: Record a short test and play it back locally to confirm capture.

Cabling & grounding: Use balanced XLR cables; eliminate ground loops.
Gain staging: Lower preamp gain to avoid clipping; raise signal at the source if too low.
Interference: Keep power/USB cables away from audio/video lines; disable wireless devices near the unit.
Sample-rate mismatch: Ensure all devices use the same sample rate (e.g., 48 kHz).

CPU/IO load: Check system CPU, GPU, and disk I/O; close unnecessary apps/processes.
Disk speed: Use SSDs or RAID suitable for sustained write throughput; verify disk health.
Encoding settings: Lower bitrate/resolution or enable hardware encoding if supported.
Network streams: For IP inputs, check packet loss and increase jitter buffer or use wired connections.

Storage path & permissions: Confirm the recorder has write access to the target folder; check available free space.
Filesystem limits: Avoid FAT/FAT32 for large files; use NTFS, exFAT, or ext4 as appropriate.
Graceful shutdown: Always stop recordings before powering down; check for unexpected power loss—use UPS.
Run disk checks: Repair filesystem errors and replace failing drives.

Delay compensation: Use the system’s audiovisual delay/sync offset setting to align tracks.
Buffering/latency: Increase audio/video buffer sizes; prefer hardware clocks (word clock) or genlock for pro setups.
Capture chain consistency: Ensure cameras and audio interfaces use stable clocks/sample rates.

Network settings: Verify IP, gateway, DNS and port-forwarding (if remote) in Network → Settings.
Firewall/NAT: Open required ports and allow the app through local firewalls; use STUN/relay if NAT traversal is required.
Bandwidth: Confirm upstream bandwidth meets streaming bitrate plus overhead.
Credentials & HTTPS: Check user accounts, RTMP/RTSP URLs, and certificate validity if using secure streams.

Firmware/software update: Update to the latest stable firmware and application builds (back up configs first).
Corrupted config: Restore a known-good configuration or factory reset if necessary.
Hardware checks: Reseat memory, storage, and expansion cards; run hardware diagnostics.
Logs: Collect system/application logs and note timestamps for support.

Event triggers: Verify motion/alarm or control inputs are enabled and mapped to recording events.
Log retention: Check retention and indexing settings; reindex database if available.
Permissions: Ensure users have rights to see event metadata.

Reproduce: Capture steps to reproduce issue and note exact time.
Restart: Reboot the recorder and source devices.
Logs: Collect application, system, and network logs.
Backup: Export current configuration before making major changes.
Update: Apply firmware/software updates.
Isolate: Swap cables/devices to isolate faulty hardware.
Support: If unresolved, provide support with logs, firmware version, hardware model, and reproduction steps.

If you want, I can convert this into a printable checklist or a one-page troubleshooting flowchart—specify which.
