The Nest Doorbell (wired, 2nd generation) uses its camera and software to watch the doorstep, and it can tell a person, an animal, a vehicle and a package, so motion detection problems are about the zones, the sensitivity and the position. Open the Google Home app, tap the doorbell, then Settings, Activity detection, and review the sensitivity and the activity zones. A zone drawn over the porch and path keeps a busy street out of alerts, and a zone that is too large catches cars and trees.
The checks in more detail
Owners on Nest's community report cameras that stay idle and miss events, and Scos's guide lists the usual causes: a low sensitivity, a camera angled at a bright window or the sky, and a weak Wi-Fi link that stops events from uploading. The doorbell is powered by the doorbell wiring and a transformer, so a weak supply can make it restart and miss events; check the power page. The doorbell sits at about chest height and should look straight at the approach path. Visitors who walk straight at the doorbell are detected more reliably than those who cross the view quickly.
A bright porch light that flickers or insects drawn to the light can trigger false alerts, as can rain and shadows from trees, so adjust the sensitivity and zones. Home and Away can turn notifications off when you are home. Make sure the doorbell is online and that notifications are on. Test by walking up to the door and watching for the alert. If the doorbell sees people but not packages, package detection is a subscription feature on some plans. Clean the lens with a soft cloth, as a smudge reduces detection range. Restart the doorbell by pressing its button, and keep the firmware current.
If events are missed with good settings and a strong signal, contact Google Nest support with times and examples. Weather and time of day influence detection: heavy rain can look like movement to the camera, and a very dark porch reduces the picture's detail, so a porch light on a sensor helps by lighting visitors for the camera. If a delivery person leaves a package and walks away quickly, a low sensitivity may miss them, and a higher sensitivity with a tight zone around the door works better than a general setting for the whole view.
