Hello,

Andy, the link referenced in document says that the file is no longer available. Has there been a more recent version released?

Thanks,
Steve
 
I'm finding this firmware to be problematic with my 49225T-HN ....I've tried resetting to factory defaults a few times now...it works ok for a short time but then the PTZ presets stop working and I end up with a washed out image...never had this with other firmware versions...anyone else finding this?
 
the link no longer works - is this still the latest firmware? and if so does someone have the latest version they can send me?

Updated to this 2 or 3 months ago on my 12203T-GN, 1A203T-GN, 49225T-HN, and SD22404T-GN. Been fine.

Is there any information about the changes?
 
does anyone else use this firmware on their 49225T-HN ?? Mine constantly switches over to PAL, loses all PTZ presets, and time zones switches to Beijing?!.....VERY unstable...should I roll back to the previous one? which would that be?
I've reset to factory defaults and re-did all settings like 100 times now...SUPER frustrating
 
I'm sorry for you. This is my old version.

I have a Dahua DH-SD22204T-GN and trying to use it with 3 different onvif capable NVR's, not working. Firmware update fails, no matter which I use, older or newer.

Does anyone know which firmware and how to update successfully ?
 
ok i have a DH SD22204T-GN with firmware 2016 and i cant get it upgraded, so i do understand that my cam has a smaller hardware memory so it will only accept the old firmware.
The link to the dropbox works but the file is gone can any one get that file for me ?
And i really want to use firefox without the plugin and i was wondering when i get the matching firmware will it work on firefox ?
Many thanks
 
Any chance there is a newer firmware for the 16mb version of the SD22204T-GN ?

It now runs 2.400.0000.16.R.T1.484, build : 2016-05-17 and it no longer displays video in the web (the plugin doesn't work for me). Also I have issues using this camera in the Imou Life app.

All above posted versions of the firmware won't work. I think they are too large for the camera memory.
