The invention discloses water and dry beach safety monitoring equipment. The equipment comprises a bracket playing a bearing effect, and a float ball playing a buoyancy support effect, wherein the float ball and the bracket are mutually connected to form an entire external contour which presents a triangle on a lookdown or an upward direction. The monitoring equipment disclosed by the invention aims at providing novel water and dry beach safety monitoring equipment for the problem that the existing water and dry beach safety monitoring equipment cannot take both floatability and stability into consideration. The shape of the equipment can be improved to perform wind-resistant design on the basis of maintaining the weight of the monitoring equipment to be unchanged, and the equipment stability is improved in the premise of not reducing the equipment floatability. The monitoring equipment can be compatible with the data collection sensitivity and smaller data fluctuation range, thereby obtaining more accurate monitoring data.
