Disney cruise ships are all equipped with overboard detection systems, which can help cut down response times by notifying crew members. At least one such system developed for vessels or other maritime structures uses thermal cameras and micro radars to detect those kinds of incidents.

The Disney Dream rescue team pulled the girl and her father into a small boat on Sunday as the cruise ship was returning to Fort Lauderdale, Florida, from the Bahamas on the last day of the voyage, according to Disney and passengers who recorded the rescue on video.
