I just bought a Reolink camera, as opposed to the cloud-only ones. It’s quite nice, requires no account anywhere for it to work including person/pet/vehicle detection. Has FTP configuration so you can have the device upload footage to an FTP server of your choosing, or just leave it on the MicroSD card.
While I don’t have a home assistant center, I’m sure this one has those capabilities.
Back in the day, people would put these up for home CB antennas. Bunch of people would all show up to help out, it was like the Amish raising a pole barn, except with a ton of beer. Somebody would bring a power auger to dig the hole, someone would have a wheelbarrow, people brought shovels. Garden hose to mix the quickcrete in the wheelbarrow and up she goes.
I don’t recall ever seeing any safety harnesses, either. Ah, the 1970s.
