I am using an Android TV Box as a NVR remote monitor on a LAN that is using a big screen TV. It is connected to a HIKVISION 7716 NVR on the LAN via IP and can view all cameras, etc. However, the image quality is way below the image quality using the iVMS on a Windows PC. I discovered that the Android App only connects to the SUB-Stream, not the Main Stream. I suspect that that is the source of my problem. Is there a similar NVR Viewing Android App that can connect to the Main Stream?
