Technical issues, clues, and solutions

If you can’t find what you’re looking for here, try the troubleshooting section at axis.com/support.

Problems upgrading the device software

Upgrade failure

If the upgrade fails, the device reloads the previous version. The most common reason is that the wrong device software file has been uploaded. Check that the name of the file corresponds to your device and try again.
