Appendix C - Updating the Firmware
The AXIS 2120 camera firmware is stored in Flash memory. Thi s memory is provided by a
silicon chip that, just like any other ROM device, retains data content even after power is
removed. Flash memory is unique because it allows its data to be erased and re-written.
This means that you can install firmware updates for your AXIS 21 20 as soon as they
become available - without having to replace any parts. New firmware can be simply
loaded into the AXIS 2120 over the network.

Obtaining Updated Firmware

The latest version of the AXIS 2120 camera firmware is available free of charge from the
Axis website at www.axis.com or from your local distributor.

Upgrading the Firmware

The AXIS 2120 firmware is upgraded over the network using FTP. See the detailed
instructions supplied with each new release.
Important!
• Always read the upgrade instructions available with each new release, prior to upgrading your firm-
ware.
• Downloading normally takes between 30 seconds and 10 minutes, although it can take longer. After
starting the download, you should always wait at least 20 minutes before power-cycling the AXIS
2120 - even if you suspect the download procedure has failed.
• In controlled environments, flash memory upgrades provide a very safe method for updating firm-
ware. However, flash products can become damaged if the upgrade operation is not performed cor-
rectly. Your dealer reserves the right to charge for any repair attributable to faulty upgrading by the
user.
