I’ve been tempted to look into existing solutions or maybe even creating my own solution for a dash camera that can also stream live to a cloud or RTP service. The main problem is internet access and bandwidth availability, especially with a multi-channel camera.

Ideally, I’d design something that plugs into a small computer that can be mounted in the trunk and writes the footage and optional metadata from a OBD-II reader or other devices (GPS, accelerometer, etc) to a local SSD pair with replication in place. There would then be a special switch that triggers a cloud transfer of the last few minutes before and a live upload of real time footage until stopped or a loss of power/connectivity. This would be in addition to a local recording being saved to a separate partition. It would act as a black box for a car too.

You could use LTE networks, but they are normally saturated in populated areas or unreliable in rural areas. Starlink is expensive and needs more hardware. Maybe something that just scans for public WiFi or home WiFi would be useful enough.

This. Take a look at a breakdown of the RF spectrum provided by the FCC and then consider how many different signals are passing through you and your surroundings each day. Here is a Wiki link with a chart.

I’ve seen delta 8 lube in a smoke shop, so I am not surprised.

Phone manufacturers have per-carrier configuration packages that enable various functions in the device based on what the carrier wants and supports within the network. Things like MMS, hotspot, voice over Wi-Fi, and other features can be configured this way. If a phone supports a function, but the carrier doesn’t and plans to support later on, the phone carrier bundle can have that function disabled and then deploy an update later to enable it.
