While some baby monitor brands offer limited or no extra features, others have all the bells and whistles you could imagine! Some of these include pan/tilt capabilities, infrared night vision cameras for use in complete darkness, smartphone connectivity so that parents can check on their baby while they're out to dinner or shopping around town, high sensitivity microphones that allow them to hear every breath and coo from anywhere in the house - even if it's completely silent, multiple camera connections so that each parent can watch one baby independently without interference between devices- this is great when both parents are working outside of them but want to keep tabs on a baby.
