What's the best software to turn an old iPhone (or Android phone?) into a security camera?

The concept does seem good, they certainly have more capable hardware and cost less than a lot of network attached cameras.

There are a few apps on the App Store: iPCamera for example (https://itunes.apple.com/us/app/ipcamera-high-end-network-ca...), it provides an MJPEG stream that you can process with a camera monitoring software like ZoneMinder.

There are also a few open-source projects with this kind feature: StreamIt for example (https://github.com/twittemb/StreamIt), which also provides an MJPEG stream.

This would be the most basic stuff.

MJPEG is however not the most efficient (~200Kb/s networking). There are also some "video" streaming projects like https://github.com/shogo4405/HaishinKit.swift or https://github.com/wlanjie/lf.swift, which provide MP4/RTMP/HLS streams and could be processed with a camera monitoring software like Shinobi (https://shinobi.video).

I hope this helps!

Not an answer, but this seems like it would be a fun, and fairly painless side-project. I've never tried writing something for streaming video over a network so it seems like it would be a good learning experience.
