Abstract: A surveillance camera includes a housing containing a camera module, an optical reflection component, and a first driving component. The camera module has a fixed position and is disposed opposite to a reflective surface of the optical reflection component, which is disposed in a transparent portion of the housing. The reflective surface is positioned at an angle with respect to the input axis of the camera module to reflect light received through the transparent housing portion to the camera module. The camera module captures an image by detecting the light reflected to it by the reflective surface. The first driving component drives the optical reflection component to rotate the reflective surface around the input axis of the camera module, such that the camera module captures images carried by light from different directions through the transparent portion of the housing without rotation of the camera module itself.

Abstract: A beam splitter plate configured to dispose obliquely in a transmission path of an imaging beam of a camera and comprising a transmissive plate, and a beam splitter film supported on the transmissive plate and parallel to the transmissive plate, wherein the beam splitter film is configured to reflect visible light and transmit near-infrared light, or the beam splitter film is configured to reflect the near-infrared light and transmit the visible light, wherein a thickness of the transmissive plate satisfies that transmission path lengths of the visible light and the near-infrared light in the imaging beam in the transmissive plate are both less than a projection length of the beam splitter film on an optical axis of the imaging beam.
