I found these two small square like objects. Not sure on weight. They're both silver but the left one has a black lens.

They looks like metal cameras. They don't move and I just noticed them the other day when bringing in the trash cans. They appear to look like cameras. They don't make noise and they don't move. I saw them under my neighbors fence pointed towards my driveway

Several tall poles with spiral "hook" in a park

The poles (about 5-6 of them) were spread around the park, not in any pattern, not along paths and not on any type of playing field. Too tall to reach the hook (at least 3m tall). A friend who lives nearby says he has never seen any plants in pots or similar things hanging from them, since that was my initial guess. Found in this park: https://maps.app.goo.gl/UT3Tp3gG5bRpRuWr8
