Abstract: An optical path switching method is applied to a surveillance module. The method includes: determining a target magnification; and (i) when the target magnification is less than or equal to a maximum magnification of a camera, setting a magnification of the camera to the target magnification, determining that a reflection element is at a first location or in a first working state, and performing image capture by using the camera alone; or (ii) when the target magnification is greater than a maximum magnification of the camera, setting a magnification of the camera to a first magnification, determining that the reflection element is at a second location or in a second working state, and performing image capture by using both the camera and a teleconverter, where a product of the first magnification and a magnification of the teleconverter is the target magnification. The method increases a surveillance distance while reducing costs.
