Hey there, Steph. We appreciate the feedback you shared about the Nest Doorbell (battery), and we hear your concern about the event detection. This feature depends on the camera settings that you select. You can choose which events your doorbell can detect and record (people, motion, package, etc.). You can change the settings like adjusting video quality, wake-up sensitivity, length of video clips, time between recorded events, and using activity zones to monitor specific areas.For more help, feel free to reach us anytime here: https://support.google.com/googlenest/gethelp
