Security camera sending too many false motion alerts

Usually sensitivity set too high, motion zones covering the street or moving foliage, or headlights and shadows triggering it. Narrowing zones and lowering sensitivity helps most.

Symptoms

  • Constant notifications for cars, shadows, or leaves
  • Alerts several times an hour with nothing actually happening
  • Notification fatigue causing you to ignore real alerts
  • More false alerts on windy days or at night

Likely causes

  • CommonMotion zone includes the street, sidewalk, or a treePassing cars and blowing branches are among the most common false-trigger sources.
  • CommonMotion sensitivity set too highHigh sensitivity picks up small movements like shadows, insects, or light changes.
  • PossibleHeadlights or reflections sweeping across the frame at nightPassing car headlights are a frequent nighttime false-trigger cause.
  • PossiblePerson/vehicle-only smart detection not enabledCameras with AI-based detection filters can ignore non-human/vehicle motion if the feature is turned on.
  • Less commonCamera facing a busy street or a spot with a lot of ambient movementSome locations are inherently prone to frequent legitimate-but-unwanted triggers.

What to do

  1. Redraw motion zones to exclude the street, sidewalk, and any trees or bushes in view.
  2. Lower the motion sensitivity setting and test over a day to see if false alerts drop.
  3. Enable person-only or vehicle/person smart detection filtering if your camera supports it.
  4. Angle the camera slightly downward to focus on your property rather than the public street.
  5. Reduce or block a light source that sweeps across the frame, like a neighbor's motion light.
  6. Set a schedule to reduce sensitivity during high-traffic daytime hours if nighttime alerts are the main concern.
  7. Review a week of alerts and fine-tune settings based on what's actually triggering them.
