> I've finally got my code up on GitHub with a README.md that should help with the initial setup and some sample images in the Wiki. This is the evolution of: [Security Cameras with AI Person Detection](https://discourse.nodered.org/t/final-version-of-security-cameras-with-ai-person-detection/9510) All the code can be downloaded from: [Python AI-Person-Detector with node-red controller/viewer](https://github.com/wb666greene/AI-Person-Detector/blob/master/README.md) If you give it a try and have any issues, raise them on the Github and together we will improve the Wiki. This current code has been running for about six weeks now on an i7-4500U "Mini PC" so I think …

Google recently added support for the Coral TPU AI accelerator to Windows 10. A friend gave me a Windows 10 "mini pc" and asked if I could get my security system add-on running on it.

I succeeded, but I don't have Windows equivalents for the bash scripts used by node-red for start, stop, powerdown, delete old files, etc.

If you have a TPU and want to give it a try on Windows 10 here is how I did it:

### Some performance tests with Windows 10 running on an i3-4025U

- 5 Onvif 720p cams : ~32.9 fps, probably limited by the rate Onvif snapshots can be had by HTTP requests.
- 4 RTSP HD (1080p) : ~11.8 fps, rtsp streams from the DVR are set for 3 fps each.
- 4 RTSP UHD (4K) : ~12.4 fps, rtsp streams from 4K DVR are set for 3 fps each.
- 5 Onvif, 4 HD (1080p) : ~28.1 fps.
- 4 HD and 4 UHD : ~15.7 fps, this is clearly overloaded.
- 8 HD rtsp streams : ~23.9 fps, basically every frame, much better with HD than UHD streams.

Edit:  
I should add that the Coral TPU USB accelerator has come down in price, it was originally ~$80, its now available for ~$60. It and an old Windows10 PC with USB3, and a couple of ~$30 netcams from Amazon (or your existing security DVR) you can try the AI enhancement without diving into IOT class devices.
