Abstract: The present application provides a dielectric filter, including a body part, a dielectric resonator, a cavity is formed in the body part, and a support kit is disposed at a bottom of the cavity. The dielectric resonator, including a dielectric body and at least two adjusting holes disposed on the dielectric body, is contained in the cavity and is disposed on the support kit. The dielectric body has a first mirror plane and a second mirror plane, which are perpendicular to each other and penetrate through the top plane and the bottom plane of the dielectric body, and any two of the at least two adjusting holes are not mirror symmetric relative to the first mirror plane or the second mirror plane.

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.
