I'm taking a different tack on this.
I've enabled the Cargo cam and am going to direct that to a raspi4 the Pi4 will connect to the truck hostpot for internet and bluetooth to the OBD2 I have installed for telemetry.
I'm also adding a vidcap to the pi4 which will take the input from a 360cam/dvr that also records with a shock sense trigger.
The DVR will have a wifi SD adapter to connect the filesystem of the DVR to the pi4 so the pi can upload the video to offsite storage.
So any time I open the cargo cam input, I'll see the 360cam or telemetry info I am pulling for the pi4. I'll also be able to do TaserDT type things via the pi4 through OBD2 like lights, windows, horn, fan cooldown, Line lock (I'll almost certainly never use that).
I'll secure it all by having a VPN tunnel back to my offsite storage. if someone steals my car, I'll have video of it happening, GPS coords of the truck last known, and the ability to disable the truck (until they start trashing stuff like pulling to obd2).
I think it will also do well to keep valet/mechanics held to account on hotdogging.
I'll also be able to screen cast wirelessly from my phone to the pi4 should I want to.
the BOM I have at the moment is:
Alfaobd2 60 (I already have this)
MX+ obd2 99 (Already have this)
Pi4 ~100 (Already have this)
wifi SD ~60
