I have a Reolink Argus 2 with a solar panel. It has two advantages for me:
1. it can be operated energy-autonomously
2. it transmits data via WiFi
This eliminates the need for complex cabling and data can be streamed via Netgear Hotspot Nighthawk M5. There is also an app for the camera that allows you to view the stream via your smartphone.
Finally, I want to query the stream via a Raspberry Pi 4. In this case, I will use the system as a rear view camera.
I have not tested the system yet, but I am convinced that it will work as desired.
