In usb camera moniterZoneminder master 1.35.12~20201101103027-focal brightness settings can not be changed using the settings button .

This shortcoming is in zoneminder 1.34.22-focal1 also.

The brightness settings works correctly only in zoneminder old versions ( 1.32 etc)
No error logs indicated pertaining to this problem

I don't have any local usb cameras, so you will need to test for me.

Insert the following debug statement into line 42 of settings.php:
https://github.com/ZoneMinder/zoneminde ... gs.php#L42
The add the following, after line 43:
https://github.com/ZoneMinder/zoneminde ... gs.php#L43
Try to change a value in settings and then post what shows up in your logs.

Dear Sir
After editing the settings.php at /usr/share/zoneminder/www/includes/actions/settings.php
For the code at first link
log file is below
For the code at second link
log file is below
The brightness settings didn't work for both occasions

At what point do the warnings appear in the first screenshot...when you first click the settings button, when you make a change to one of the parameters, when you click save, something else?

I don't see either of the warnings I had you insert into settings.php.
What I'm looking to see is what appeared in the log, immediately after clicking the save button.

Oh, and it looks like $zmuOutput is an array so change the second warning to:

Dear Sir
According to the first link there are no warnings in the log

For the second link when you change brightness and save there is an error indicated in the log as follows
The brightness can't be adjusted in both cases

The page source of the monitor settings popup window is annexed below

According to the above page source , the brightness setting file may not be the settings.php at /usr/share/zoneminder/www/includes/actions/
