I was working with Raspberry Pis, starting with a college honors project, around 2018. For a while, I thought about building a network of surveillance cameras around the interior of my home. The Raspberry Pi seemed like a tempting platform to hook up a bunch of cameras to it. Sadly, I could not find a backend surveillance app or system that was suitable for running such a network. The best one I found was some kind of modular Linux app that was for-pay, and actually seemed based in Russia or something, and personally I wasn't comfortable about handing over my domestic surveillance needs to Russia! I also considered exterior sensors, such as a camera, or perhaps a nice little weather station, outside on my balcony, running on the little Raspberry Pi. Then I recalled two things: I live in the Sonoran Desert, where the desert highs can go up around 115℉, and any plant on my balcony was guaranteed to wither and die, not to mention the blowing dust and thunderstorms we have. I determined that there was basically no way to house or protect a Raspberry Pi, as well as supply it with connectivity and electric power, and keep it outside on the balcony in conditions where I'd benefit from those active sensors. Sad but true! |
There are non-IP cameras and coax interfaces, which would expose a USB video device on any Linux system, RPi included.
Plenty of software to handle that, though don't know what's the state of the art.
