Looking to buy a NVR1108H. But I can't find information on how I could either see the live camera feed or recordings on my phone when I am away from the wi-fi, the cameras and the nvr is on. Is it possible to install/side-load applications like tailscale on to this NVR? Would any ONVIF compliant app somehow connect with this NVR - I can't foresee this happening - but want to understand how everyone's doing this.
