Abstract:
1. A water monitor system comprising: a camera having an infrared image sensor to provide an image data stream of a surface of a body of water; a computer-readable medium having computer-executable components containing instructions for analyzing objects located within the image data stream; and a processor adapted to analyze the image data stream in accordance with the computer-executable components to determine whether one of the objects is a person in the body of water submerged for more than a predetermined period of time by: counting how many people are at the surface of the body of water based on the image data stream to form a count; maintaining a running tally of how many people are in the body of water based on the image data stream; and comparing the running tally to the count to determine whether a person in the body of water is submerged for more than the predetermined period of time.
