What caught my eye was my PS V3 caught a hummingbird from about 12 ft away. Going to be careful here–Descriptive Alerts caught it. I’m not sure if a “normal event” would have tagged it.
Also beware the whole bird detection is in its infancy. Even if you had a BCP in the bird Feeder, only in the last couple of weeks has it seemed to properly I’d a bird as a bird vs a pet or motion.
