Where can I find a new Firmware for RLC-823A? not the Beta-Vrsion but the final new one?

Thank you for your help, but my HD Cams (Firmware) have no fields with brigtness or kontrast.
In Chapter "Display > Day & Night" is possible to set "auto, color and BW" but nothing more.

In case of Argus PT 2k the options "brightness" and "scene" are available

Argus PT and Argus PT 2k produce pictures with very different brightness.

I have two Argus PT and one Argus PT 2k. Since a few month the pictures from Argus PT are much more darker then the pictures from 2k verson from the same location.

Argus PT works with  FW Ver 1202_491_352_11   (installed since 10 and 1 month)
Argus PT 1k works with Ver 3.0.0.715_21112344

I am not able to find a option brighter/darker in the app.
Where can I change a picture quality?

Firmware Download Site works not properly, I am only able to choice NVR or IP Cam (...) and it is everthing, search function not works, it is not possible to download any firmware.
Tested under WIN10 (Firefox/Edge) and WIN7 Firefox

I use many cams from Reolink (Battery and POE). Could you implement the measurement and display of the housing temperature? This could help to recognize the "about" ambient temperature. I know that it will not be the exact temperature of the environment, but only a trend

It is not possible, during Camera-Firmware-Updates by USB via NVR to navigate in subdirectories.
All FW-Update-File must be stored in root, no subdirectiores are visible.
Can you add a possibility to navigate to USB-Stick-subdirectiories ?

@reolink-fiona
Ok, thanks for the answer.
I have got this came yesterday with small Quick-Guide, I can proof this cam in real time
