I unironically really like how easy ubiquiti security cameras are to setup/access remotely.

Also their AI cameras are great for tracking specific people/animals, so if you just want to quickly find anytime a certain person showed up on your cameras, you can just filter for that. Biggest downside to the AI cameras are their price though.

They also offer super stalker cameras if you really want to spy on your neighbours (pic related, 4k AI cameras with 31x optical zoom)
