i have eufy spotlight camera , anke cameras and recording box and a ring doorbell
imo the ring has the worse picture but sends alerts to phone and you can talk but monthly fee and battery to change
the eufy spotlight has a lot better picture also sends alerts to phone , you can talk , set alarm off and no monthly fee
the anke cameras and box very good picture and can access from phone but no alerts - just continous recording then overlaps after couple of weeks / depending how many cameras and settting
out of them 3 i would say eufy fits the bill best - just like putting up spotlight then connecting to internet /leave it alone
i am no expert by a long shot but thats what i would use for my mum
