Upgrade instructions:
         
Important: 

0. Upgrade to version 2.42 is only possible if version 2.12 or later 
   is installed. 

1. Make sure that "active applications" such as continuous transmission 
   of images via ftp or smtp from the Axis Network Camera  are disabled 
   prior to initiating upgrade.

2. Make sure to take notes of your application/layout and other 
   settings prior to upgrading since these settings will be 
   lost during upgrade. 

3. You must be at the command prompt and in the directory that 
   contains the Upgrade File.
   Example: C:\Axis\2420\2_42>

4. Open an ftp connection to the unit you want to upgrade from a 
   command prompt.
   (Do not use a Windows based FTP-program for this, use only command 
   line FTP programs!)

5. Login as root. The default password for the root user is "pass" 
   unless changed by the user. You must be logged in as the root user 
   to upgrade the unit.

6. Change to binary transfer mode by typing "bin" and press enter.

7. Type "hash" and press enter. (This will allow you to see how the 
   upgrade progresses)

8. Type the command "put XXX.bin flash_all" where XXX.bin is replaced
   by the name of the name of upgrade file you downloaded 
   (and maybe decompressed) from our site. It is typically named 
   2420_242.bin or axis2420.bin. 

9. Wait for the flash load to finish, this may take 1-10 minutes.
   Always wait at least 10 minutes for the flash upgrade to complete.

10. Your unit will automatically restart using the new firmware. 

11. Reconfigure your settings.

The new improved audio functionality uses G723 as the default audio codec, 
which gives a higher compression compared to the former G721. It uses 
singlepart instead of multipart communication to reduce overhead. For 
backward compatibility change the following parameters in the product: 

root.Audiod.audioEncoding="G721"
root.Audiod.httpMessageType="multipart"


Known limitations in version 2.42 
=================================

L1. Up to 4MB of RAM memory is available for pre/post alarm image storage.
