Validate Mobotix Pink Purple Tint Issue
Pink or purple tint on Mobotix camera footage typically indicates sensor calibration failure or IR filter malfunction. This issue may originate from incorrect firmware configurations, environmental factors affecting the camera's optics, or hardware degradation. The solution involves targeted diagnostics through MxManagementCenter and brand-specific tools like MxThinClient. This guide assumes network expertise and familiarity with enterprise-grade IP cameras.
Quick Checks for Mobotix Cameras
Before diving into advanced troubleshooting, perform these immediate checks:
- Verify VMS dashboard status: Ensure the camera appears online in your VMS platform (e.g. Wisenet WAVE or Avigilon Control Center). A disconnected state may indicate network or power issues.
- Check PoE link light: Confirm the switch port shows a stable PoE negotiation (Class 3 or higher). If the port shows Class 0, investigate power budget exhaustion or faulty switch ports.
- Ping the camera IP: From the switch or VMS server, execute
ping <camera_ip>to confirm basic connectivity. A 100% packet loss suggests network misconfiguration. - Examine status LED: On Mobotix cameras, a solid green LED indicates normal operation. A blinking red LED may signal firmware corruption or hardware failure.
- Power cycle via PoE: Disable the switch port for 30 seconds, then re-enable. This can resolve temporary network or power glitches.
Troubleshoot Network Configuration Issues
Verify VLAN Assignment
Incorrect VLAN settings are a common root cause of Mobotix video distortion. Navigate to Network > Camera Settings in MxManagementCenter and ensure the camera's VLAN matches the switch port configuration. Use the Network Health Check tool to automatically validate VLAN compliance. If mismatches are detected, update the switch port settings to match the camera's VLAN. Misconfigured VLANs can fragment network traffic, preventing proper communication with the VMS and causing sensor data corruption.
Validate PoE Budget
Ensure the switch port is capable of delivering sufficient power (802.3af/at/bt) for the camera model. For example, the MOBOTIX MOVE SD-340-IR requires PoE++ (802.3bt). Use the Power Budget Calculator in MxManagementCenter to identify over-subscribed ports. If power exhaustion is detected, reconfigure the switch port or deploy a PoE injector. A common symptom of PoE budget exhaustion is intermittent video dropouts with colour distortion.
Check DHCP Lease Assignment
In MxManagementCenter, navigate to Network > DHCP Settings and confirm the camera receives a lease from the correct VLAN. A lease from an incorrect subnet may prevent proper firmware updates or VMS integration. Use the DHCP Lease Viewer tool to identify lease conflicts or exhaustion. If the camera is assigned an IP from an unintended subnet, update the DHCP scope to ensure it aligns with the camera's VLAN.
Diagnose VMS Integration Issues
Re-Register Camera in VMS
If the camera appears offline in your VMS (e.g. Wisenet WAVE or Axis Camera Station), re-register it via the Camera Registration Wizard in MxManagementCenter. Navigate to Camera > VMS Integration > Re-Registration and follow the prompts. This process ensures the VMS has the correct RTSP stream URL and authentication credentials. If the camera fails to re-register, check the Event Log for errors related to VMS communication.
Verify Stream Profile Configuration
In MxManagementCenter, access Camera > Stream Profiles and confirm the selected profile matches your VMS requirements. Select RTSP (TCP) for stable networks or RTSP (UDP) for low-latency applications. Incorrect stream profile settings can cause intermittent video distortion. If using multicast, ensure IGMP Snooping is enabled on the switch to prevent packet loss.
Address Firmware and Analytics Issues
Confirm Firmware Channel Subscription
Navigate to Camera > Firmware Management in MxManagementCenter and ensure the camera is registered to the correct firmware channel (stable or beta). Outdated firmware can cause sensor calibration issues leading to colour distortion. Use the Staged Rollout feature to apply updates incrementally while monitoring the camera's status in the Event Log section. If the camera fails to update, check for Firmware Channel Subscription errors in the Event Log.
Calibrate Thermal Sensor (if applicable)
For Mobotix thermal cameras, ensure the Thermal Analytics Status is active in MxManagementCenter. Navigate to Camera > Thermal Analytics > Calibration and follow the prompts to recalibrate the sensor. Incorrect calibration can cause false heat maps and colour distortion in the video feed. If the sensor fails to calibrate, check for Thermal Sensor Error messages in the Event Log and consider replacing the sensor.
Advanced Diagnostics and Fixes
Use MxThinClient for Network Analysis
Launch MxThinClient and connect to the camera via the Network Diagnostics tool. Capture packets between the camera and VMS to identify RTSP stream interruptions or multicast issues. If packet loss is detected, implement QoS policies on your switch to prioritize video traffic. Verify the camera's RTSP stream URL in MxManagementCenter under Stream Profiles to ensure correct authentication mode and transport protocol.
Check MicroSD Card Health
Mobotix cameras store video recordings internally on the camera's microSD card. Use the Storage Health Tool in MxManagementCenter to check card endurance and wear. Replace the card if it shows signs of degradation. Use high-endurance industrial-grade microSD cards rated for continuous recording. If the card is failing, the camera may display pink/purple tint during playback or recording.
Escalate to Enterprise Support
Initiate RMA Process
If all troubleshooting steps fail, initiate the RMA process via Mobotix's official support portal. Provide the Event Log and Network Diagnostics reports from MxThinClient. For hardware failures, request a replacement camera and return the faulty unit. Enterprise customers may qualify for SLA-based support with guaranteed resolution times.
Root Causes of Mobotix Pink/Purple Tint
The most common causes of pink/purple tint on Mobotix cameras are:
- Stuck IR cut filter: Prevents proper day/night mode switching, causing colour distortion.
- Sensor calibration failure: Often due to outdated firmware or thermal sensor miscalibration.
- MicroSD card degradation: Can corrupt video files, leading to visible tint in playback or real-time footage.
- Network misconfiguration: VLAN mismatches or multicast issues can corrupt sensor data.
- Hardware failure: Damaged sensors or IR cut filters may require replacement.
Prevention and Long-Term Care
Schedule Firmware Updates
Use MxManagementCenter's Firmware Management tool to schedule regular updates. Ensure the camera is registered to the correct firmware channel (stable/beta) and apply updates during off-peak hours. Monitor the Event Log for any errors during the update process.
Plan PoE Budget Headroom
Ensure your switch has sufficient power headroom for all Mobotix cameras. For example, a MOBOTIX M73 requires 802.3af/at. Use the Power Budget Calculator in MxManagementCenter to avoid over-subscription. Regularly audit switch port usage to prevent unexpected power exhaustion.
Implement QoS Policies
Configure Quality of Service (QoS) policies on your switch to prioritize video traffic. Assign Mobotix cameras to a dedicated VLAN and set traffic prioritization to DSCP 46 for real-time video streams. This reduces the risk of packet loss and colour distortion.
