For Reolink cameras with smart detection, it is supported to set up maximum object size and minimum object size at the same time for the person, vehicle, or pet detection separately. If the moving object is smaller than the minimum object size or bigger than the maximum object size, it will not trigger the alarm so as to reduce the false alarm.

Applies to: Reolink WiFi cameras and PoE cameras with smart detection (E1, E1 Pro, Lumus, and add-on cameras in the NVR kits are excluded).

The guides below intend to show you how to customize such Object Size for your camera via a web browser.

Step 1. Input the IP Address of your camera on a web browser and log in to your camera.

See how to find the IP address of your camera.


Note: Make sure your PC is connected to the same router as your camera.

Step 2. Click the Device Settings gear icon on the top right corner.


Step 3. Go to the Camera > Alarm Settings page. Scroll down to find the Object Size.

Click Set Up beside the alarm type you want to configure (Person/Vehicle/Pet; they may vary according to different camera models).


Step 4. Draw the minimum size or maximum size for such alarm type. Take Person for example:

Click the minimum size icon below to turn it yellow, then click one of the angles and drag to adjust the size of the yellow rectangle. A moving person smaller than the yellow rectangle will not trigger the alarm.


Click the maximum size icon below to turn it green, then click one of the angles and drag to adjust the size of the green rectangle. A moving person larger than the green rectangle will not trigger the alarm. 



  1. You can only set up a minimum size or a maximum size, or set up them both at the same time. If you draw both of them, make sure the green rectangle is bigger than the yellow one. 
  2. You can click the Trash Can icon to delete the unwanted minimum/Maximum rectangle.
  3. Don't forget to click Save if you have finished setting.
