Troubleshooting

Quick Solutions

Event Transmission Issues

No Events in Video Activity

No Events Appearing in GCXONE

Symptoms

• Events not appearing in Video Activity
• Alarms not being received
• Event clips not generated

Solutions

1. Verify Report Alarm is Enabled
   • Recheck More → Log → Report Alarm is enabled
   • This is critical for GCXONE to receive events
   • Save configuration after enabling
2. Check IVS Rule Status
   • Confirm IVS rule is armed and scheduled for current time
   • Verify rule is active and not disabled
   • Test rule by triggering event manually if possible
3. Verify Time Synchronization
   • Check time sync/NTP is working
   • Ensure device time matches GCXONE time
   • Verify time zone settings are correct

Too Many Alerts

Excessive Alerts

Symptoms

• Too many false alarms
• Alerts flooding the system
• Performance issues due to alert volume

Solutions

1. Tighten IVS Zones
   • Refine detection zones to focus on critical areas
   • Exclude areas with frequent non-threat movement
   • Adjust zone boundaries to reduce false positives
2. Avoid Generic Motion
   • Disable Motion Detection if possible
   • Use IVS (Tripwire/Intrusion) instead
   • If Motion is required, tune Sensitivity ~70 and Threshold 5
   • Avoid noisy areas for Motion Detection
3. Adjust Detection Parameters
   • Fine-tune sensitivity levels
   • Adjust effective target settings (Human, Motor Vehicle)
   • Review tracking duration settings

Discovery Issues

Device Discovery Failures

Symptoms

• Device not discovered in GCXONE
• Discovery process fails
• Sensors not appearing

Solutions

1. Verify Credentials
   • Check username and password are correct
   • Use the dedicated NXG user created in Step 1
   • Test credentials in Dahua web interface
2. Check Role Permissions
   • Verify user has required permissions (Manual control, System, Camera, System info, Event)
   • Ensure Search and Live permissions are granted for cameras
   • Check camera-specific permissions are applied
3. Verify Network Connectivity
   • Check ports (80/443/554/HTTP API) are open
   • Test device reachability from GCXONE
   • Verify correct VLAN configuration
   • Check IP allowlist if site uses whitelisting
4. Try Different Protocols
   • Try HTTP vs HTTPS based on site policy
   • Test ONVIF discovery if proprietary fails
   • Verify protocol settings match device configuration

Live View Issues

Live View Stuttering

Symptoms

• Live view stutters or freezes
• Poor video quality
• Buffering issues

Solutions

1. Lower Substream Bitrate/FPS
   • Reduce substream bitrate to decrease bandwidth usage
   • Lower frame rate if necessary
   • Adjust resolution if bandwidth is limited
2. Confirm Dual-Stream Profile
   • Verify dual-stream is properly configured
   • Check main stream and substream profiles
   • Ensure GCXONE is using appropriate stream
3. Check Network Bandwidth
   • Verify sufficient bandwidth is available
   • Check for network congestion
   • Review bandwidth requirements for your setup

Quick Reference

✅ Common Fixes

• Enable Log → Report Alarm
• Verify IVS rules are armed and scheduled
• Check time sync/NTP
• Verify credentials and permissions
• Test network connectivity
• Use IVS instead of Motion Detection

❌ Common Mistakes

• Not enabling Report Alarm
• Using Motion Detection instead of IVS
• Incorrect credentials or permissions
• Network connectivity issues
• Time zone mismatch
• Using admin account instead of dedicated user
