A six/seven figure donation for these companies is...nothing. While I'm all for grabbing my face eating leopard popcorn, I'm not sure I'd say this falls under that category. This amount of money doesn't feel like trying to buy favors
more like "please don't specifically target us with your wrath of incompetence."
I would recommend PoE security cameras. You probably want support for RTSP / ONVIF.
I have some Amcrest cameras talking to Frigate. It is completely local---cameras on a separate VLAN that can't talk to the Internet, footage is recorded on a server running Frigate. Works very well for me. No vendor lock-in is also nice!
