I cant comment on the camera issue. The satellite details I can.
The Iridium RockBlock(RockBLOCK 9603 | Rock Seven) unit has no GPS , only sends serial data and you pay per message, I forget the max # of bytes. There’s a line rental fee as well. Easy to use as there’s an Arduino Lib for it already.
The Smartone C (SmartOne C | Globalstar CA) has GPS with motion detection, geofencing ect. & two dry contact inputs that will trigger a packet.
You need to either buy from an VAR ( value added reseller) or set yourself up as one.
It also has a serial port and send custom messages from your Boron’s or Argon’s serial port if no cell or wifi is available,
Note: It uses CRC and the result can be forwarded to an email or http post endpoint.
The packet is HEX and many bytes and with the exception of the serial data ( if any) need to be broken into binary bits for decoding so it is a beast to set up
I was able to grind all the status bits and serial data out into usable data using Losant(https://www.losant.com/).
