How does this handle motion detection? Anyone tried it?

I have a bunch of Nest cameras and some cheaper Tapo cameras.

The "motion detection" is night and day different. The Tapo does some basic frame-diffing and it's awful. Shadows? DING DING DiNG MOTION DETECTED! gust of wind made some blades of grass move? Motion! Spider? Motion motion motion! Turn down the sensitivity a notch or two and it won't notice a human walk across the frame 2 meters away. The Tapo ones claim to be smart but twigs and leaves still trigger pet/person/motion alerts. It makes them essentially useless.

The Nest cameras are so much better and their "human" detected is usually zero-false-negatives at the cost of one or two false-positives perhaps once every 3 or 4 months, and their app is superior (tapo one frequently needs to be false-killed to load clips). Yes I am aware that the nest ones are streaming back to google 24/7.

Tldr: naive frame-diffing sucks for this sort of thing if used outside. An open source implementation that has accurate and reliable "human detection" would be amazing. Doesn't need to be "AI" - I would hope that there is some sort of computationally reasonable OpenCV way of doing person detection. Perhaps wait for frame-diffing to flag motion then feed it to a more expensive algorithm?

The tapo cameras do this on cam. They can even report it to the NVR system, completely local with ONVIF.

Nest does it in the cloud. Obviously it's more capable but it also means Google grabs all your video: https://support.google.com/googlehome/answer/16594324?hl=en#...

Try the motion Linux package, it can connect to tapos over SDP and then you can run Yolo or any other solution on the output

Seriously… how hard is it to setup an RPi with a camera and offload the detection to some open source software? Last time I checked there projects performing animal, face and even license plates reckon, extraction and db recording of “who”, “when”, “what” using cheap cameras and an RPi.

It's actually pretty darn easy nowadays and i'm so glad its the case! Frigate is amazing and the detection package is of your choosing (hardware dependant) and everything is customizable too.

Frigate is pretty cool if you need motion detection. If you don't it's a bit wasteful because it still keeps the whole decoding pipeline active. I've switched to LightNVR that doesn't do that. I have enough alarm sensors (motion and door entry) so I don't need motion on the cams as well. I just record 24/7 for evidence keeping.
