Avigilon PoE Not Powering Camera? Enterprise Fix Guide

Your Avigilon camera is failing to power via PoE, and the issue is likely related to network configuration, PoE budget allocation, or firmware compatibility. This guide provides step-by-step troubleshooting for IT professionals using Avigilon Control Center (ACC) and Avigilon Unity Video. Root causes include VLAN misconfiguration, insufficient PoE wattage, or firmware incompatibility. Follow these steps to resolve the issue.

Quick Fixes for Avigilon PoE Power Issues

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

  • Check VMS Dashboard Status: In Avigilon Unity Video, navigate to Cameras → [device] → Device Health. Look for PoE Negotiation Failed or No Power alerts.
  • Verify PoE Link Light: Confirm the switch port’s PoE LED is active (green or amber). If the LED is off, the switch may not be sending power.
  • Ping the Camera IP: Use the Ping Tool in ACC to verify the camera is reachable. If unreachable, check the switch port configuration.
  • Check Camera Status LED: If the camera’s LED is amber or off, it may not be receiving power. Ensure the camera is connected to a PoE-compliant switch port.
  • Power Cycle the Switch Port: Disable and re-enable the switch port in the switch’s web interface. This can resolve transient PoE negotiation issues.

Verify Your Avigilon Camera's Network Configuration

Check VLAN Assignment

Avigilon cameras must be on a dedicated surveillance VLAN with routing enabled to the ACC server subnet. In the switch’s web interface, verify the camera’s port is assigned to the correct VLAN. If not, reconfigure the port to the surveillance VLAN. In Avigilon Unity Video, navigate to Network → VLAN Settings and confirm the VLAN ID matches the switch configuration.

Validate PoE Budget

Use the PoE Budget Tool in Avigilon Control Center to calculate wattage requirements for all devices on the network. Ensure the switch has sufficient wattage allocated for the camera. If the switch is a Midspan device, confirm it is correctly configured to inject power. If the switch is an Endspan device, ensure it is set to Class 3 (40W) for the camera’s port.

Confirm DHCP Lease

Ensure the camera is receiving a valid IP address via DHCP. In the switch’s web interface, check the port’s DHCP Lease status. If the lease is expired or the camera is not receiving an IP, reconfigure the DHCP scope in the ACC server to include the camera’s MAC address.

Diagnose Avigilon Unity Video Connectivity Issues

Check ONVIF Profile Settings

If the camera is connected to a third-party VMS, ensure ONVIF Profile S is enabled. In the camera’s web interface, navigate to Network → Integration Settings and verify ONVIF Profile S is selected. If using ACC, check Stream Profile Configuration under Video Settings to ensure the RTSP URL is correctly formatted (e.g. rtsp://[camera_ip]:550/cam/realmonitor?channel=1&stream=0).

Test RTSP Stream Directly

If the RTSP stream fails in ACC, test the URL directly in a browser or VLC player. Replace [camera_ip] with the camera’s actual IP address. If the stream fails, check the camera’s RTSP Port in the ACC Device Management portal and ensure it matches the URL.

Factory Reset and Enterprise Support Escalation

Perform a Factory Reset

If the camera is still not powering, perform a factory reset. For the H6A Dome Camera, press and hold the factory reset button on the camera body for 30 seconds until the status LED flashes amber rapidly. For the H6A PTZ Camera, press and hold the reset button on the camera body for 30 seconds until the LED flashes amber rapidly. For the H4 Pro 7K Camera, press and hold the reset button on the rear of the camera for 20 seconds until the status LED changes to flashing amber.

Escalate to Enterprise Support

If the camera still fails to power after a factory reset, contact Avigilon Enterprise Support. Provide the Device Health report from Avigilon Unity Video, the PoE Budget Tool output, and a Packet Capture from the ACC server. This will help support engineers identify the root cause quickly.

Root Causes and Enterprise Considerations

PoE Budget Exhaustion

Avigilon cameras require 40W (Class 3) PoE power. If the switch’s PoE budget is exhausted, the camera will not receive power. Use the PoE Budget Tool in ACC to calculate wattage requirements for all devices on the network and ensure the switch has headroom. If the switch is a Midspan device, confirm it is correctly configured to inject power.

VLAN Misconfiguration

Avigilon cameras must be on a dedicated surveillance VLAN with routing enabled to the ACC server subnet. If the VLAN is misconfigured, the camera will not receive power. In the switch’s web interface, verify the camera’s port is assigned to the correct VLAN. In Avigilon Unity Video, navigate to Network → VLAN Settings and confirm the VLAN ID matches the switch configuration.

Firmware Incompatibility

Ensure the camera’s firmware is up to date. In the ACC Device Management portal, check the Firmware Channel is set to Stable. If a staged rollout is active, use the Rollback Tool to revert to a previous version. Check for Firmware Compatibility in the ACC server’s Device Management portal.

UK-Specific Considerations

In the UK, ensure the ACC server has internet access on port 443 for Avigilon Unity Cloud connectivity. If the camera is on a site registered in the Avigilon Unity Cloud portal, ensure the site is correctly configured. For sites with double NAT, enable modem mode or DMZ to the ACC server.

Prevention and Long-Term Maintenance

Schedule Firmware Updates

Use the Firmware Deployment Tool in ACC to schedule regular firmware updates. Ensure the Firmware Channel is set to Stable to avoid compatibility issues. Monitor the Device Health report in Avigilon Unity Video to ensure all cameras are up to date.

Monitor PoE Budget

Use the PoE Budget Tool in ACC to monitor wattage usage for all devices on the network. Ensure switches have sufficient headroom for new devices. If the budget is exhausted, consider upgrading to a PoE++ (802.3bt) switch for higher wattage.

Enable QoS and SNMP Monitoring

Configure QoS policies on the switch to prioritize video traffic. Use SNMP monitoring in ACC to track network performance and identify potential issues before they occur. Regularly review Device Health reports in Avigilon Unity Video to ensure all cameras are functioning correctly.

Frequently Asked Questions

Verify your switch supports 802.3af/at and the camera is on a dedicated VLAN with routing enabled to the ACC server subnet. In Avigilon Unity Video, check **Device Health** under **Network Diagnostics**. If PoE negotiation fails, ensure the switch port is configured for **LLDP** and **CDP** discovery. Use the **PoE Budget Tool** in Avigilon Control Center to confirm the switch has sufficient wattage. If the port shows Class 0, manually set the port to **Class 3** (40W) via the switch's web interface.

In Avigilon Unity Video, navigate to **Cameras → [device] → Integration Settings**. Ensure **ONVIF Profile S** is enabled for third-party VMS compatibility. If using ACC, check **Stream Profile Configuration** under **Video Settings**. Verify the **RTSP URL** in ACC is correctly formatted (e.g. `rtsp://[camera_ip]:554/cam/realmonitor?channel=1&stream=0`). If the stream fails, test the URL directly in a browser or VLC player.

Access the camera's web interface (via **Avigilon Unity Video → Camera Settings → Network**) and ensure **Firmware Channel** is set to **Stable**. If a staged rollout is active, use the **Rollback Tool** in Avigilon Control Center to revert to a previous version. Check for **Firmware Compatibility** in the ACC server's **Device Management** portal. If the camera is stuck in **Pending Update**, manually trigger a **Force Update** via the **Firmware Deployment** tool.

If **Device Health** in Avigilon Unity Video shows **PoE Negotiation Failed**, use the **Packet Capture Tool** in ACC to inspect traffic between the switch and camera. Look for **LLDP** or **CDP** packets. If missing, ensure the switch supports **LLDP** and the camera is configured to send **LLDP** frames. If the switch does not support **LLDP**, manually set the port to **Class 3** (40W) via the switch's web interface. Verify the camera's **PoE Class** in the ACC **Device Management** portal matches the switch's configuration.

If the camera is not powering via PoE but works with a power adapter, check the **PoE Budget** in Avigilon Control Center. Ensure the switch has sufficient wattage allocated for the camera. If the switch is a **Midspan** device, confirm it is correctly configured to inject power. If the switch is an **Endspan** device, ensure it is set to **Class 3** (40W). Use the **PoE Budget Tool** in ACC to calculate wattage requirements for all devices on the network and ensure the switch has headroom.
