+1 to this. A steel frame 90s mountain bike with 26" wheels, some maintenance know how and about $100 in parts will get you thousands of km of riding with much less trouble compared to a fancy aluminium/carbon frame with hydraulic breaks and a drivetrain that locks the moment something goes slightly out of tolerance.

Only caveat is needing to buy some tools, but good tools will last.

+1 for frigate. I have some old V2 wyze cameras with openmiko for rtsp functionality.

The existence of foss projects should never exclude the creation of alternatives if someone wants to try.
