---------------------------------------------------------------------

Upgrade instructions:
         
Important: 

0. Upgrade to version 2.40 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_40>

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_240.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.


RELEASE 2.40
============


News in 2.40
============


2.40:1  Improved support for the AXIS 2191 audio module. Added support 
 	for the G723 compression standard. Various new options introduced, 
	such as: slope filter, canceling of line and acoustic echo, 
	noise reduction, forcing of client audio settings.

2.40:2  New version of the ActiveX Camera Control (2,20,0,6) including 
	the improved audio support.

2.40:3  Added a snapshot button on the view pages.
	To see the Snapshot button, select this option under Layout, and 
	enable personal layout settings.

2.40:4  The 2CIF image resolution has been added (704x240 - NTSC or 
	704x288 - PAL). 2CIF has the same number of lines as CIF, but 
	twice the number of pixels per line. The image is re-scaled to 
	4CIF in the viewer, which has a slight effect on the image quality. 
	However, the 2CIF option eliminates the motion blur in the regular 
	4CIF video caused by the interlaced sensor, and it requires half 
	the bandwidth. 

2.40:5	The base file name for the image buffers has been increased to
	128 characters.

2.40:6  After a flash upgrade using flash_all, the BOOTPEnabled parameter 
	is restored to the value configured before the upgrade.

2.40:7  The text in the picture is extended to allow characters between 
	ASCII 32 and ASCII 255.


Corrections in 2.40 since 2.34:
=================================

2.40:8  Improved uploads 'when input goes high' - images are no longer  
       	truncated.

2.40:9  The scheduler can now handle logical AND combinations when 
       	dealing with triggers.

2.40:10 The FTP server deamon (sftpd) now opens the back channel data 
	connection on port 20 instead of on a random port.

2.40:11 Corrected a memory issue in the FTP application.

2.40:12 If the flash upgrade procedure was aborted while erasing the 
       	flash, the programming was never completed. This problem is 
	now corrected.

2.40:13 The mail client complies with the RFC, regarding bare LF. Some 
       	servers, such as qmail, were rejecting the mails generated by the 
       	client.

2.40:14 Applications now switch from primary to secondary time without 
	occasionally causing the product to reboot.

2.40:15 Corrected minor layout problems on operation pages.

2.40:16 Upload with large images no longer stops when the images fill 
	the RAM space allocated to buffers. The application should 
	restart as soon as the images can fit.

2.40:17 Corrected problem with getting more images uploaded than necessary 
	when using alarm application and "when motion stops" trigger.

2.40:18 Phone numbers starting with the # character are now correctly 
	handled by PPP.

2.40:19 PPP no longer stops dialing out after 241 calls.

2.40:20 The delta time between images no longer wraps around one 
	second.

2.40:21 Enabled multicast traffic receiving from range of addresses 
	that were not working before.

2.40:22	Negotiated values for network speed 10Mbps and half/full duplex 
	are now correctly reported.

2.40:23 Some stability problems seen when the product was installed 
	in heavy network load environments have been corrected.


Application developer / scripting in 2.40:

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 2.40 
===================================

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