Convenience. Unless you live right near the border, it’s probably faster/easier to shop in your own state than drive all the way to another.
But if you do live near the border of a state without a sales tax, then it’s pretty common to shop in the neighboring state, especially for larger purchases.
I know I’m a bit late to the conversation, so I don’t know if this is still helpful… But I have a camera with “AI Detection” built into it and it appears to send alerts via its ONVIF connection. I’ve disabled motion and other detectors on my NVR (AgentNVR) and instead configured it to just wait for an alert from the camera itself to start recording. It’s been working quite well.
My initial plan was to use a coral TPU and frigate, but the Coral/Gasket drivers appear to be pretty old and I couldn’t get them to work properly, myself.
