Object size is an effective way to reduce false alarms. If the moving objects are smaller than the minimum object size or larger than the maximum object size, it will not trigger the alarm, reducing false alarms caused by spider webs, light changes, and raindrops. This section will present the ways to set up object sizes for your Reolink cameras. 

Applies to: Reolink cameras that support smart detection.

Important Notes:

  • The size of the object and its placement are not important.  If you reopen the settings and find that the frame’s position has changed, this is normal and does not affect the object size settings you have made. 
  • You can only set up a minimum size or a maximum size, or set up both at the same time. If you draw both of them, make sure the Maximum Object (blue rectangle) is bigger than the Minimum Object (yellow one).
  • If you want to redraw the minimum/maximum object, just click the Trash Can icon and repeat the above operations.
  • For Dual-lens series, object size is set for two lenses (Camera 1/Camera 2) together, and cannot be set separately.
