Troubleshooting Guide for an Axis Camera That Keeps Disconnecting
An Axis network camera that frequently disconnects is a significant liability, creating gaps in your security coverage. These professional-grade devices are known for their reliability, so intermittent connection drops often point to an underlying issue in the network infrastructure, power supply, or device configuration. This guide provides a systematic approach to diagnosing and resolving the problem.
## Understanding the Common Causes of Disconnection
For a hardwired device like an Axis camera, disconnections are typically caused by one of the following:
- Network Infrastructure: Problems with cables, switches, or routers.
- Power Supply: Unstable or insufficient power, especially when using Power over Ethernet (PoE).
- IP Address Conflicts: Two devices on the same network with the same IP address.
- Firmware/Software Issues: Bugs in the camera's firmware.
- Bandwidth Limitations: The network cannot handle the camera's video stream bitrate.
## Step 1: Physical Layer and Power Inspection
Start with the most fundamental components: the cables and power source.
- Inspect the Ethernet Cable: A faulty network cable is a common culprit. Check the entire length of the cable for any signs of physical damage, kinks, or sharp bends. Ensure the RJ45 connectors at both ends are securely clipped in place and the pins are not damaged.
- Test with a New Cable: The easiest way to rule out a cable fault is to temporarily connect the camera to the network switch using a short, known-good patch cable. If the connection becomes stable, the original cable run is the problem.
- Check the Network Port: Try connecting the camera to a different port on your network switch or router. A faulty port can cause intermittent connection drops. Observe the port's link lights to ensure they indicate a stable connection.
- Analyse the Power Source (PoE): If you are using Power over Ethernet, ensure your switch or PoE injector can provide adequate power. Axis cameras have specific power requirements (e.g., PoE Class 3). Check the power budget of your PoE switch to confirm it is not overloaded, especially if multiple cameras or other PoE devices are connected. An underpowered camera may reboot or disconnect when certain functions, like the IR illuminators, are activated.
## Step 2: Network Configuration and IP Addressing
If the physical connections are solid, the next step is to investigate the camera's network settings.
### Resolving IP Address Conflicts
An IP conflict is a frequent cause of "now you see it, now you don't" behaviour.
- Use a Static IP Address: The most robust solution is to assign a static IP address to your Axis camera. This ensures its address never changes and cannot be accidentally assigned to another device by the DHCP server. You can configure this in the camera's web interface under Settings > System > Network > TCP/IP.
- DHCP Reservation: Alternatively, you can configure a DHCP reservation on your router or server. This links the camera's unique MAC address to a specific IP address, effectively making its DHCP-assigned address permanent.
### Pinging the Camera
A continuous ping test can help you determine the extent of the disconnections.
- Open a command prompt or terminal on a computer on the same network.
- Type
ping [camera's IP address] -t(on Windows) orping [camera's IP address](on macOS/Linux). - Let this run and watch for "Request timed out" or other errors. This will show you exactly when and how often the connection is dropping.
## Step 3: Firmware and Software Checks
Software bugs can introduce instability.
- Update Camera Firmware: Axis regularly releases firmware updates that include bug fixes, security patches, and performance improvements. Log in to the camera's web interface and check the current firmware version. Compare this with the latest version available for your camera model on the Axis Communications website and perform an upgrade if necessary.
- Check Video Bitrate: If the camera is configured to use a very high bitrate and your network is congested, it can lead to packet loss and disconnections. Try temporarily lowering the resolution or increasing the compression (lowering the quality) to reduce the bitrate and see if the connection stabilises. This can help diagnose network bandwidth limitations.
By methodically examining the physical connections, network settings, and firmware, you can effectively isolate the cause of the disconnections and restore the stable, reliable performance expected from your Axis camera.
