Have been thinking about this for a couple years. I have old phones kicking around. Battery shot, hardware dated, but the camera(s) and mic and antennas still work. Would be cool if there were a way to set them up (powered) to stream audio/video or even take stills at intervals (or motion-activated) and then sync the content to the rest of the devices on my network.
I don’t know how complex the programming for something like this would be. But I suspect it’s trivial for those who do know.
Haven might do the trick. It’s motion activated and can stream content. Made by the guardian project / Snowden to warn you if someone breaks into your hotel room. Open source, too
FYI, the Haven F-Droid repo has seemingly not been updated in 4 years. Latest available .apk is from 2019.
Damn, thank you so much!
