Troubleshooting
If you suspect a problem is being caused by incorrect configuration or some other minor
problem, consult the troubleshooting guide below.
Upgrading the Firmware
Firmware is software that determines the functionality of the network camera. One of your
first actions when troubleshooting a problem should be to check the current firmware. The
latest version may contain a correction that fixes your particular problem. The current
firmware version in your camera is displayed on the Basic Configuration or About. For the
latest firmware of the camera, please contact with your product administrator.
Detailed instructions on how to perform the upgrade process are provided with each new
release. See also the Maintenancen/ Upgrade for more information.
