Patient video monitoring systems and methods for thermal detection of liquids

A system for monitoring a patient in a patient area having one or more detection zones, the system comprising:

• one or more cameras including an infrared thermography device comprising;
• a user interface;
• and
• a computing system configured to:
• receive a chronological series of frames from the one or more cameras;
• identify liquid candidates by comparing a current frame with a plurality of previous frames of the chronological series and determining a difference between at least one pixel characteristic in the current frame as compared to the at least one pixel characteristic in the previous frames to identify groups of pixels as the liquid candidates, the at least one pixel characteristic comprising at least one of temperatures, spectral responses, and positions of pixels;
• determine locations of the liquid candidates;
• identify thermal signatures of the liquid candidates using at least the infrared thermography device;
• determine types of liquids of the liquid candidates based on the locations and thermal signatures of the liquid candidates;
• and
• generate an alert with the user interface corresponding to the determined types of liquids.
