A:Answer Unfortunately, they say a 35 pound animal will trigger the motion detector. But my 20 pound Pomeranian always triggers ours. For our RING security system, we have to arm our home as HOME when we leave. If we set it as AWAY, the dog sets the motion off. For the flood light camera out in the back, the sensitivity can be adjusted to not pick up people or large animals. Mine is set to pick up everything, so i always see alerts at 4am when the neighborhood raccoon or opposum makes their rounds checking trashcans.
