.. is a free, self-hosted alternative to Shodan Images, with an additional camera validation step.
Images is one of the premium features of Shodan, you need a paid account to use it. This is a self-hosted alternative to it, that works with only a (paid) API key.
I will keep the acquiring of such API keys for free as an exercise to the reader :)
Most of the cams you'd find on Shodan Images don't work btw — they either time out or the channel can't be found. To make sure all cameras collected work, camwall has an additional probing step (hence the ffmpeg dependency for ffprobe) that validates each camera.
You must have ruby 3.0.* with bundler.
The only extra dependency that won't be installed by bundler is ffmpeg. Install that using your package manager.
If you use nix (the package manager), there is a devenv.sh file that sets up everything.
