I tested again my zoneminder today with the settings written below and with the
following results :
- my "source" was initially "red" ;
- I clicked on it to open the "general" "source" "timestamp" "buffers" "misc"
window and without changing any setting - which had been working before - I
clicked on the "save" button ;
- my "source" was now "orange" or "green",... according to the "function" choice
(monitor, modect, record,...).
This "save without changing any setting" was described in the Full Circle
magazine.
To conclude, it was quite uneasy to set up Zoneminder but now, as it works
nicely, I can tell this software is excellent.
