Abstract

The invention relates to a sound wave warning method, system and device and a storage medium, the method is used for a sound wave warning device, the sound wave warning device comprises a loudspeaker capable of adjusting the size of a cone opening, and the method comprises the following steps: determining the distance between a target event and the sound wave warning device; determining the size of the opening of the cone based on the distance, and giving an alarm based on the sound wave warning device; wherein the size of the opening of the cone corresponds to the distance, so that sound waves can be transmitted in a small range in a concentrated manner, energy attenuation of the sound waves is reduced, noise influence on a non-target area is reduced, and the problems that in the prior art, sound wave alarm is spread all around, sound wave energy is rapidly attenuated, and noise influence is large are solved.

Description

technical field [0001] The present application relates to the technical field of security monitoring, and in particular, to a sound wave warning method, system, device and storage medium. Background technique [0002] In the use scenario of security monitoring, when the network camera detects abnormal events such as object movement, area intrusion, and cross-border, the network camera can start the alarm function to notify relevant personnel; in the unattended monitoring area, the camera with the warning function It can be used to warn intruders or cross-border personnel in place of guard personnel. In the prior art, mainly by connecting the camera with the sound and light alarm device, when the camera detects an abnormal event, the sound and light warning is triggered, or the external fill light triggers the flashing when monitoring abnormal behavior to achieve the purpose of warning. The loudspeaker shouts or warns the intrusion target. [0003] However, whether it is an...
