Day and night mode switching method for monitoring equipment and monitoring equipment

The invention provides a day and night mode switching method for monitoring equipment and the monitoring equipment, and relates to the technical field of security and protection. The method comprisesthe following steps: acquiring a first monitoring image in a current monitoring mode; determining a brightness characteristic value of the first monitoring image; under the condition that the currentmonitoring mode is a day mode, when it is determined that the brightness characteristic value is smaller than a first preset brightness value, determining an edge detail characteristic value of the first monitoring image; and when the edge detail feature value is greater than or equal to a preset edge detail feature value, determining that the current monitoring mode is not switched. According tothe method, whether the day mode is switched or not is judged through combination of the brightness characteristic value and the edge detail characteristic value. The situation of misjudgment of day and night mode switching is
