Everything shown in the photo is included. Operation has been confirmed. New batteries, used only for operation confirmation, are also included. This is a type where you get an app on your smartphone and can observe the baby on the monitor within the app. It notifies you with an alarm for body temperature, rolling over, and breathing. During the anxious baby stage, it was very useful as a source of reassurance because a loud alarm would sound if movement stopped. It is no longer needed as the baby has grown, so I am selling it. It is the type that attaches to diapers, so it has been wiped with alcohol. Please only purchase if you understand that this is a used item. 260333
