hi guys,

been going crazy here with my Hikvision NVR model ds-7216huhi-k2

I need to have access to my snapshots for a display device. (home automation but it is irrelevant)

I can have access via my browser using the well known url replace Y with the channel and i get a snapshot

the only issue is that it only returns something for analogue cams connected to the nvr and not the ip ones.
so yes snapshot on channel 16 but not on 17/18 and rest of the ip ones.

any idea why?
