Avigilon Pink Purple Tint on Video? Enterprise Fix Guide

Address Avigilon Pink Purple Tint on Video

This guide targets IT administrators and security integrators dealing with persistent pink or purple tint on Avigilon IP cameras. The root cause often lies in network misconfigurations, firmware incompatibility, or sensor calibration drift. By following these steps, you can isolate and resolve the issue within 30 minutes using Avigilon-specific tools like the Device Health Monitor and Firmware Management portal.

Quick Checks for Avigilon Cameras

Before diving into advanced diagnostics, perform these 30-second checks:

1. Verify VMS Dashboard Status

In Avigilon Control Center, locate the affected camera and confirm its status. If it shows Offline but responds to ping, proceed to the next step.

2. Check PoE Link Light

Inspect the switch port for the camera. A solid green light indicates stable power. If the light is amber or off, verify the PoE budget on the switch and ensure no other devices are starving the port.

3. Ping the Camera IP

Open a terminal and ping the camera's IP address. If the response is inconsistent or times out, check for VLAN mismatches or DHCP scope exhaustion.

4. Power Cycle via Switch

Disable the switch port for 10 seconds, then re-enable it. This forces the camera to renegotiate PoE and reset its network stack.

5. Check Status LED

Observe the camera's front panel. A steady amber light indicates normal operation. A flashing red light may signal a hardware fault or firmware error.

Deep Troubleshooting: Network and VMS Integration

Verify VLAN Configuration

1. Access Avigilon Control Center → Device Health → Network.
2. Confirm the camera is assigned to the correct VLAN. If mismatched, update the VLAN ID in the switch port configuration.
3. Reapply network settings via the Setup Wizard in Avigilon Unity Video.
4. Ensure QoS prioritisation is enabled for video streams to prevent packet loss.

Diagnose Firmware Incompatibility

1. Use the Device Health Monitor in ACC to check for firmware updates.
2. If the camera shows Firmware Update Pending, ensure it is registered on the correct firmware channel (stable/beta).
3. For H4 Pro 7K models, verify firmware compatibility with ACC Enterprise licence requirements.
4. If issues persist, perform a staged firmware rollback via the Firmware Management tool in the ACC portal.

Troubleshoot RTSP Stream Issues

1. Access Network Diagnostics in Avigilon Unity Video and run a Multicast Test.
2. If IGMP snooping is enabled on the switch, disable it temporarily to confirm it is not blocking RTSP streams.
3. Check the RTSP Stream Profile in ACC to ensure H.265 encoding is selected.
4. Re-register the camera in ACC and reapply the ONVIF Profile S configuration.

Address UMD or AI Interference

1. In Avigilon Control Center, navigate to Analytics → UMD Settings.
2. Temporarily disable the Unusual Motion Detection (UMD) module if active.
3. For H6A Dome cameras, use the Appearance Search tool in ACC Enterprise to verify if AI processing is interfering with colour balance.
4. If enabled, disable AI features during troubleshooting.

Resolve Storage-Related Tint Issues

1. In Avigilon Control Center, run a Storage Health Check.
2. If the NVR4 Standard reports Disk Health Degraded, replace the affected drive.
3. Reapply the 30MP resolution profile in ACC for H4 Pro 7K cameras.
4. Enable Edge Storage Failover to prevent buffer overflow from corrupting video streams.
5. Initiate a VMS Database Repair via the ACC maintenance tools if the issue persists.

Advanced Steps: Factory Reset and Enterprise Support

Factory Reset for H6A Cameras

1. For H6A Dome: Press and hold the factory reset button on the camera body (accessible after removing from mount) for 30 seconds until the status LED flashes amber rapidly.
2. For H6A PTZ: Press and hold the reset button on the camera body for 30 seconds until the amber LED flashes rapidly.
3. For H4 Pro 7K: Press and hold the reset button on the rear of the camera for 20 seconds until the status LED changes to flashing amber.
4. Reapply network settings via Avigilon Unity Video after reset.

Packet Capture and Protocol Analysis

1. Use a network analyser (e.g. Wireshark) to capture RTSP traffic from the camera.
2. Filter for RTSP and H.265 streams to identify encoding issues.
3. Check for multicast traffic and IGMP errors that may disrupt video delivery.

VMS Database Consistency Check

1. In Avigilon Control Center, navigate to Maintenance Tools → VMS Database Repair.
2. Run the repair utility to resolve inconsistencies in the database.
3. Reboot the ACC server after completion and reapply camera configurations.

Escalate to Enterprise Support

1. If basic troubleshooting fails, contact Avigilon Support via support.avigilon.com.
2. Provide the VMS logs, firmware version, and Device Health Monitor reports.
3. Request an RMA if hardware failure is suspected.

Root Causes of Avigilon Pink Purple Tint

Network-Level Causes

• VLAN mismatches disrupt RTSP stream integrity, causing chromatic aberration.
• PoE budget exhaustion on switches may starve cameras, leading to sensor instability.
• DHCP scope exhaustion in camera VLANs can cause incorrect IP assignments.

VMS Integration Issues

• Licensing conflicts in ACC Enterprise may disable AI features, affecting colour balance.
• Database corruption can corrupt video metadata, resulting in tinted footage.
• Incompatible stream profiles (e.g. H.264 instead of H.265) may degrade video quality.

Firmware Management Pitfalls

• Stable firmware channels may lack critical bug fixes for tint issues.
• Staged rollouts can leave some cameras on outdated firmware, causing inconsistencies.
• Firmware rollback is required if updates introduce new tint-related bugs.

Long-Term Avigilon Maintenance Tips

Enterprise Maintenance Practices

1. Schedule firmware updates quarterly using the Firmware Management tool.
2. Monitor Device Health in ACC for early signs of sensor drift or network instability.
3. Plan PoE budgets with 20% headroom for future camera additions.

Network Best Practices

• Create a dedicated VLAN for cameras to isolate traffic.
• Enable QoS prioritisation for video streams to prevent packet loss.
• Use SNMP monitoring to track switch port utilisation and PoE status.

Full Disclosure

We built scOS to address exactly this: the complexity of managing enterprise camera fleets across VLANs. scOS uses permanently powered cameras connected via ethernet.

Avigilon Pink Purple Tint Repair vs. Replacement Guide

Camera Lifecycle Planning

• Wired cameras (e.g. H4 Pro 7K) last 5-8 years but may require sensor replacement after 4 years.
• Battery cameras degrade after 3-5 years due to battery cycle limitations.
• NVR HDDs (e.g. NVR4 Standard) should be replaced every 3-5 years with surveillance-rated drives.
• UK consumers have 6 years under the Consumer Rights Act 2015 to claim faulty hardware.

Troubleshooting Timeframe

• Basic fixes: 10-15 minutes.
• Advanced steps: 30+ minutes may indicate hardware failure.
• Replace cameras if troubleshooting exceeds 30 minutes without success.
