Mail carriers typically open the gate and leave it open not knowing dogs are loose and then your dogs are gone. Now you can lock your gate and put the doorbell outside the gate. Works pretty well, don't forget to take the plastic covering off the battery of the doorbell portion. The sounds and rings are plentiful but not that great and the sound is tinny. The volume doesn't get really high but at least they give you two so you can spread them out in the house, not sure the further away one will pick up yet though
