Video Streaming Troubleshooting

What Video Streaming Troubleshooting Covers​

This guide helps you resolve video streaming issues in GCXONE — from no video display to buffering, connection drops, and Local Mode problems.

How It Works​

  1. No Video Display

Symptoms: Black screen, "No video available" message, or camera shows online but no stream appears.

  • Verify the device is powered on and connected to the network
  • Ping the device IP address to confirm connectivity
  • Verify username and password in GCXONE device configuration
  • Check RTSP port 554 is open and not blocked by the firewall
  • Verify the RTSP stream path is correct for your device manufacturer
  • Confirm the codec is H.264 or H.265 — update browser if needed (Chrome recommended)
  • Restart the camera or device
  1. Poor Video Quality

Symptoms: Pixelated or blurry video, choppy playback, low resolution.

  • Access the device web interface and increase the bitrate (recommended 2–4 Mbps for 1080p)
  • Check available bandwidth and reduce stream quality in GCXONE to Medium or Low if needed
  • Enable GreenStream (Auto quality) in GCXONE settings
  • Use secondary streams for grid views and limit concurrent streams
  • Test network latency — use Local Mode for on-site workstations
  1. Buffering and Stuttering

Symptoms: Video pauses frequently, loading spinner appears often, playback is choppy.

  • Reduce stream quality and limit number of concurrent streams
  • Close unused video windows
  • Test for packet loss by running an extended ping to the device IP
  • Check network cables, switches, and routing
  • Restart the device if overloaded
  1. Connection Drops or Timeouts

Symptoms: Stream disconnects frequently, "Connection lost" messages, stream stops after a period of time.

  • Test network stability with a continuous ping
  • Check cables, switch and router stability, and WiFi interference
  • Increase timeout in GCXONE streaming settings to 30–60 seconds
  • Adjust firewall timeout settings to allow persistent connections
  • Reduce concurrent connections to the device and restart if needed
  1. Slow Stream Startup

Symptoms: Video takes a long time to load, extended loading spinner, delay before first frame.

  • Use Local Mode for on-site access
  • Check device CPU and memory usage — restart if overloaded
  • Verify the RTSP path is correct and test directly with VLC or a similar tool
  • Update device firmware
  1. Audio Issues

Symptoms: No audio with video, audio out of sync, poor audio quality.

  • Enable audio in both device settings and GCXONE camera configuration
  • Verify audio codec is G.711, AAC, or PCM
  • Update browser to the latest version
  • For sync issues: adjust buffer settings or use Local Mode if available
  1. Local Mode Issues

Symptoms: Local Mode enabled but still using cloud, no P2P connection, high latency despite Local Mode being active.

  • Verify the Local Mode service is running in Windows Services
  • Restart or reinstall the Local Mode service and check service logs for errors
  • Confirm the workstation and device are on the same network
  • Check network routing, VLAN configuration, and firewall rules
  • Note: Hanwha and Genesis Audio do not support Local Mode — use cloud streaming for these devices
  • If auto-discovery fails, manually configure device IPs in Local Mode settings

Diagnostic Tools​

Before contacting support, isolate the source of the issue:

  • Test the stream using the manufacturer's native client or software
  • If the stream works in the native client but not in GCXONE → the issue is platform-related
  • If the stream fails in both → the issue is device or network related
  • Review device logs and GCXONE platform logs for specific errors
  • Gather: device type and model, firmware version, network configuration, and error messages with timestamps

Troubleshooting Checklist​

Before contacting support, verify the following:

  • Device is online and reachable on the network
  • Required ports are open (554, 80, 443)
  • User has correct permissions (Live View or Operator)
  • RTSP path and credentials are correct
  • Browser is up to date (Chrome recommended)
  • Device has been restarted if needed
