Hello, after buying a "cheap" Hikvision NVR I am a bit unhappy with it, because I am missing a few features. Does anyone knows if there is a Dahua NVR from Andy around around 300$$ which is able to: + record mainstream AND substream + playback mainstream and substream via Android/iOS app + playback alarm recordings via via Android/iOS app (or encoding playback via App with custom bitrate?) I need this because of really bad internet connection. Even with 265+ the mainstream is unwatchable from remote. The Hikvision NVR is not able to playback the substream or record it or lower the bitrate of the playback. I know that this feature is available to swann/reolink nvrs. What is also annoying that I only can use smart playback on HDMI/VGA output. All my cams are recording 24/7, but also intrusion detection. But I cannot playback it from remote site. Not with IVMS or App. Maybe someone knows a solution.
