to monitor a cottage in remote rural area, the internet connection is 4G and so limited/expensive.
The ideal cameras should be able to
- store records locally (either on SD or to NVR)
- but should be able to access LIVE view from cloud and trigger alarms, bidirectional speak etc.

Questions are
1) it is possible to see Live camera stream from the cloud? Do I need Reolink cloud subscription for that? In Reolink Windows software there is no such option like pairing the software with cloud ID
2) if cloud access to live stream is possible, is the network traffic between camera and cloud pernament, or on-demand only?
3) can Reolink system be built with mixed power cameras - solar powered Argus Eco AND poe powered RLK8-410B4?
4) do I need Reolink NVR for that or this NVR can be replaced with any laptop PC with Reolink software?

Thanks with helping me with the answers and overall architecture.
