Hi all, does anyone know if the Hikvison DS-7616NI-I2 / 16P supports third stream. I cant live view my 5 cams at 4k as it exceeds transcoding limit, i have substream set to 720p at the moment. I would like to view them at 1920x1080 and have enabled third stream on my cameras but I cant find where to turn it on in the NVR settings. Any idea, I found a few screenshots and have tried remotely and on the local GUI but no option. thanks
