Built in baby monitor night vision system will activate when optics sense low light. 4. Press and hold monitor baby camera audio button to say hello or remotely comfort your child. Two way walkie talkie mode will call and allow double talking from the speaker. Nursery camera radio button works lullaby music. 5. Night vision baby monitor battery is designed to be operated the entire day.
