Frigate has been an overweight nightmare for me to work with. Trying to detect wildlife that are not in their classification models is basically impossible. I've been better off using motion / motioneye for a lightweight and practical approach
yeah - i've been using it for several years. it's got some issues: fails to detect cars and trucks at night (apparently it doesn't know what to do with the moving headlights); also frequently fails to detect me walking past the camera with my 4 small dogs on our morning walk; confuses farm equipment for cars and continues to record even when the object is stationary. still it's better than most of the other software i've tried.
