a DIY security camera system with object detection, recording and phone notifications – using Docker, Frigate and Home Assistant

  1. Great write up. I just did the same on my home automation server last weekend. Was going to do a write up on my blog – childof69.co.uk, but you’ve covered it nicely. What are your thoughts on accuracy of detection. I found I had to tweak threshold on each camera based on its location. There or lots of other params to tweak as well, but this seems to be the most effective. Amazed how little CPU is used for the object detection, once a TPU is installed.

      Hello Robert and congrats on breaking ground with car telemetry at your https://childof69.co.uk blog. More on this when I catch up.

      As for FRIGATE OBJECT DETECTION I am already impressed with what I have gained by using FRIGATE and ditching various (five) camera apps.
      The CPU% is around 20%. I’m variously detecting person, car, bicycles, airplanes and cats over numerous cameras.
      My object detection is never wrong (ie inaccurate) without reason and the top reason here is foliage being mistaken for a person! My complaint is that sometimes an event doesn’t show the object in the captured footage.
      I keenly look at other people’s configurations I’m just taking notes until I feel a need to say, receive alerts on a phone which of course need to be reliable. But yes I think the ‘threshold’ is the thing to tweak first.
      So … this is early days for me, it’s a work in progress.
