I live in a leased ground level floor through apartment with three entrances not including 6 accessible windows. In order to cover an entrance from inside some of the living space would need to be included. To fully cover I would need 5 cameras and have them in bedrooms too. Exterior cameras could help, but I have no authority to install. While I have no specific reason to worry, I wouldn't want my landlord to install them and be able to see what/who comes in and out of the apartment and/or raise the rent because of it.
Even just covering the 2 main entrances I find it uncomfortable to be able to know when my spouse is entering/exiting the home, I trust them.
2. Kids When you need it you need it. Like when I was isolating with covid. However it is their privacy I am concerned also as I don't want them to think it's OK to be surveilled.
3. Safety Did I leave the stove on? Not so important, but since one entrance is a galley kitchen I easily monitor this and the rear entrance.
Is the basement flooding? This is actually a big one for me. Installing one here however would mean potentially spying on the landlord which I would not do without explicit permission.
