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.
I know there is, or was. A meth head I knew used old cell phones to watch to outside of his house. I saw the app and it worked really well. The phones were all on the same wifi and had no cell service.
DroidCam.
This thing was revolutionary.
For some reason we couldn’t get the cable TV outside, so we took our other TV and then streamed from inside via DroidCam watching the TV to the TV outside to watch sports, wasn’t the best but it covered us for the day. Phones run red hot however (:
