4 sourcesThe original author of gkrellm, Bill Wilson, also made PiKrellCam. <https://billw2.github.io/pikrellcam/pikrellcam.html>
Which was/is the best Raspberry Pi Audio/Video Recording, OSD Motion Detect Program. It was made to run perfectly on a RPI Zero with its limited CPU and memory.
I was very sad to learn that Bill passed away in Oct 2021. <https://github.com/billw2/pikrellcam/issues/78#issuecomment-...>
I'm glad gkrellm got a new maintainer and continues to exist.
In GTK Krell Monitors> motion detection that doesn't actually require decoding the packets but rather looks at the motion vectors to estimate motion.
There's a very cool package for the Raspberry Pi that does this: https://github.com/billw2/pikrellcam
In Kerberos: Open-Source Video SurveillanceThat's been a dream of mine for a long time. I don't think there's anything quite like we want just yet.
However, there is a super cool open source project from the author of GKrellM (remember that from the ancient days of Linux?). He's using the Pi's built-in hardware video coder to get high quality motion detection very cheaply. The basic idea seems to be, when the encoder produced a lot of bits, there must have been some motion in the frame.
