The invention provides a water surface safety monitor consisting of a 
detector and a monitor. The 
detector is composed of a water wave 
detector, an 
infrared detector, an audio and video detector, a 
microcomputer module and a communication module, the water wave detector is composed of a plurality of detector tubes arranged in a fan shape, a 
pressure sensor is arranged in each detector tube, and each 
pressure sensor corresponds to a serial number; the 
infrared detector is composed of a plurality of 
infrared sensors and a 
scanner, the plurality of infrared sensors are arranged on the 
scanner inthe fan shape, and the 
scanner drives the infrared sensors to rotate back and forth; the audio and video detector is composed of a 
microphone, a camera, a searchlight and a cloud 
deck, and the 
microphone, camera and searchlight are mounted on the cloud 
deck; a 
signal output end of the water wave detector is connected with a 
signal input end of the 
microcomputer module, and the 
signal output ends and the signal input ends of the 
infrared detector, the audio and video detector and the communication module are connected with the signal input end and the signal output end of the 
microcomputer module; and the monitor is a 
smart device equipped with monitoring 
software and a communication module.
