Symptoms

  • People walk past the camera but no alert or recording happens
  • Motion detection worked before but stopped
  • Alerts only trigger for close, direct movement
  • Recording history shows big gaps during known activity

Likely causes

  • CommonMotion detection zone drawn too narrowCustom zones can accidentally exclude the area where activity actually happens.
  • CommonMotion sensitivity set too lowA low sensitivity setting ignores smaller or more distant movement.
  • PossibleScheduled quiet hours or disarmed mode activeMany apps let you schedule motion detection off during certain hours, which is easy to forget.
  • PossibleCamera obstructed or angle shiftedWind, an accidental bump, or growing foliage can shift the field of view away from the activity area.
  • Less commonFirmware bug or app sync issueOccasionally an update can reset or corrupt motion zone settings.

What to do

  1. Open the app and review the motion zone map to make sure it covers where activity happens.
  2. Increase motion sensitivity and test by walking through the field of view.
  3. Check for and disable any scheduled quiet hours, disarmed mode, or geofencing that turns detection off when you're home.
  4. Physically check the camera's angle and clean the lens; a shifted or blocked view will miss motion.
  5. Trim any bushes, branches, or decorations that may be blowing into the frame and confusing detection.
  6. Restart the camera and re-verify motion zone settings after the reboot.
  7. Reset motion zones to default and redraw them if settings appear corrupted.

When to call a pro

If motion detection still fails after resetting zones and sensitivity, contact the manufacturer to check for a hardware sensor issue.
