Added a speed camera watchdog for the Tesla using live Waze report-scraped data. Implemented same-street filtering to drop false positives from nearby roads. Still far from ideal. Don't ask why I needed this.

Impressive Frigate performance optimization using Gemini. My Raspberry Pi 5 + Coral TPU setup handling 8 cameras has seen a 38% drop in CPU usage, despite increasing the detection frame rate from 4 to 5. Gemini made several smart suggestions, including generating a shell script to ffprobe camera streams and determine their characteristics, splitting and…

TIL that Frigate can analyze the audio stream of RTSP cameras for certain sound types and expose these as Home Assistant sensors. Configured mine to detect barking, yelling, alarms, etc and will create automations based on these https://docs.frigate.video/configuration/audio_detectors/

Upgraded my Home Assistant to RPI 5 hardware recently mainly, so it better handles cameras in Frigate + Google Coral TPU. I am now monitoring 5 security cams at 10 FPS with ~25%-ish CPU load, the RPI 4 wasn't able to handle half of that without overheating, and 75%-ish CPU load

The Coral TPU is here, will add to my home assistant + Frigate tonight Setup complete. Only tricky part was to disable “protected mode “ for Frigate in order for it to recognize the TPU on my rPi4 running HASS OS 10.5; Currently running it on two cameras, CPU load is at 25-35%. Automations based…

Ordered a Google Coral USB Edge TPU to use with Frigate NVR + home assistant. Seems quite overpriced, I hope it isn’t a disappointment

Experimenting with sound classification using #tensorflow, sound feed from an IP camera #AI I can now take actions based on what is heard, not only what is seen #NodeRed

The 170 EUR Hikvision thermal camera arrived, impressive 160×120@25fps quality

Ordered a HIKVISON H10 160×120 25Hz IR infrared thermal imager camera for €170. Sounds too good to be true, awaiting delivery to make a detailed review. The known issue is that menu is in Chinese language only.

I didn't know that Samsung S8's camera app has built in QR code recognition, just pointing it to a QR with AP login details prompts connection UI..neat
