Diagnosing and Responding to Avigilon Hardware Failure
An Avigilon security system is a professional-grade solution designed for high reliability. However, like any electronic equipment, its hardware components can sometimes fail. A hardware failure, whether it's a camera, a network video recorder (NVR), or a server, can lead to gaps in your security coverage, loss of recorded footage, and an inability to monitor your premises. Swiftly identifying and addressing the issue is critical to minimise downtime.
This guide provides a general overview for system administrators and users on how to spot the signs of a potential hardware failure, perform initial diagnostic checks, and understand the next steps to take. Please note: Avigilon systems are typically installed and maintained by certified professionals. For any serious hardware issue, your first point of contact should always be your official Avigilon partner or installer.
Identifying Potential Hardware Failures
The signs of failure can vary depending on the component.
- Camera Failures:
- No image (black screen) in the Avigilon Control Center (ACC) client.
- Frozen or stuttering video feed.
- Distorted image, strange colours, or visual artefacts.
- The camera is shown as "Offline" or "Disconnected" in the device list.
- The camera's physical IR illuminators or status LEDs are not functioning.
- NVR / Server Failures:
- The device will not power on.
- Status lights on the front of the unit are red, amber, or blinking in an error code pattern (consult the device manual for specific codes).
- The ACC client cannot connect to the server.
- Loud or unusual noises, such as clicking or grinding from the hard drives, indicating potential drive failure.
- The system reboots unexpectedly and repeatedly.
Initial Troubleshooting Steps
Before escalating the issue, there are a few basic checks you can perform to rule out simple problems.
1. Power Cycle the Device (The "Reboot")
This is the oldest and often most effective first step in IT troubleshooting.
- For a Camera: If it's powered via PoE (Power over Ethernet), you can reboot it by unplugging the Ethernet cable, waiting 60 seconds, and plugging it back in. If it has a separate power supply, disconnect that instead.
- For an NVR or Server: Perform a graceful shutdown through the operating system if you have access. If not, press the power button to turn it off. Wait for a full minute before powering it back on. This allows all components to fully discharge and reset.
2. Check All Physical Connections
A loose cable can easily mimic a hardware failure.
- Power Cables: Ensure the power cord is securely plugged into both the Avigilon device and the wall outlet or UPS (Uninterruptible Power Supply).
- Network Cables: Check that the Ethernet cable is firmly connected at both ends (at the device and at the network switch). Look for the link lights on the network port to confirm a connection.
- Video Cables (for servers/NVRs): If you are connecting a monitor directly, ensure the VGA, HDMI, or DisplayPort cable is secure.
3. Observe Status Indicators
The LEDs on the hardware are your best diagnostic tool.
- NVR/Server: Pay close attention to the colour and pattern of the lights on the front panel. Note any specific "fault" or "error" lights that are illuminated. Check the lights on the hard drive caddies; a red or amber light often indicates a drive has failed.
- Camera: Look at the status LED on the camera itself (if accessible and visible). A lack of any light may indicate a power issue.
4. Review Software Logs
If you can still access the Avigilon Control Center software, check the system logs.
- In the ACC Client, look for the Event Log or System Log.
- Filter for errors or warnings related to the specific device. The logs may contain explicit messages like "Hard drive failure detected on NVR-01" or "Camera CAM-10 is not responding". This information is invaluable for your technician.
When to Call a Professional
If the initial troubleshooting steps above do not resolve the issue, it is time to escalate. Do not attempt to open the chassis of an NVR or server unless you are a qualified technician. Doing so can void your warranty and risk further damage.
Contact your certified Avigilon partner or installer with the following information:
- The model number of the failed device.
- A detailed description of the problem.
- The status of the indicator lights.
- Any error messages you found in the software logs.
- The troubleshooting steps you have already taken.
Providing this information will help your technician to diagnose the problem more quickly and efficiently, ensuring your security system is back up and running as soon as possible.
