I understand, Costa. Some of my neighbours have noticed and commented on the front-and-rear dash cam I got after vandalism to my car in the community, non-secure, carpark. The most common opinion is ‘What a good idea! I think I’ll get one’ when I tell them it has a parking mode triggered by movement.
Just install your front door cam and give your immediate neighbours a short, polite note and see what happens. If you bump into them in the corridors, ask what they think.
I also have one pointing out my window at a Common Property pathway which is not at all easy to spot unless you’re peering in which almost nobody would. I see possums and cats but no poo-joggers yet.
