Does anyone happen to have NHD-887 / 888 firmware V14.45.5.0_191204 handy perchance? I'm guessing it would be CHX48M_F128M_SF_ENU_swann_V14.45.5.0-191204_r8970_W.sw or similar.
I've managed to get my NDH-887s running V14.45.5.0_191204 fully operational on Synology Surveillance using custom camera profiles, including ONVIF PIR events, two way audio, decent audio quality etc. This however is only working on said firmware. I have two NDH-887s running V14.45.5.0_230321, and the firmware forces ADPCM audio and this appears to be incompatible with SS two way audio implementations. I see absolutely no benefit to the newer firmware running standalone via SS, so just want to roll it back to get two way audio.
Thanks!
P.S I will provide my custom SS camera profiles soon so that others can get a bit more life out of their 887s and 888s!
