Trying to reduce the bandwith usage in Blue Iris, as i'm actually on 16 4mp cams, 12 of these DS-2CD2042WD-I, i wanted to try to switch from H264 to H265 compression, but in the configuration page i can't find the H265 option, but looking at advertised specs these cameras should have it, ( i also have two DS-2CD2045FWD-I, and here there is the 265 opton), i also upgraded the firmware to the latest 5.5.82 with no chance. I'm missing something? Thanks in advance....
