Hi sounded ok till you mentioned reolink
with a budget camera you might be best and cheaper for you to use a WD cloud box hidden at same location as camera
never understand why people only want off site storage ….. only takes phone line or cable to be disconnected then renders your system useless….. cloud is good as second backup ….. nvrs are cheap for local storage and still works if network goes down
so two options
WD cloud unit …… only purchase cost and no ongoing charges

or
sign up to something like ibm cloud ….. but I think the price will put you off
