Namely, at least the following cases are included: the mirror component 12 does not rotate, and the lens component 11 does pitching motion or horizontal rotation relative to the bracket 10; the reflector component 12 rotates horizontally relative to the bracket 10, and the lens component 11 does not rotate; the mirror component 12 rotates horizontally relative to the bracket 10, and the lens component 11 moves in a pitching manner or rotates horizontally relative to the bracket 10; the mirror assembly 12 rotates vertically with respect to the stand 10, and the lens assembly 11 tilts or rotates horizontally with respect to the stand 10.

Referring to fig. 4, when the lens assembly 11 is stationary with respect to the holder 10 and the mirror assembly 12 is rotated with respect to the holder 10 by an angle of rotation of +15 ° to-15 °, the monitoring position is changed left and right, and the horizontal monitoring range can be expanded, and the angle of rotation of the mirror 17 can be calculated to be 15+15 — 30 °, and the monitoring range can be expanded to 30 × 2 — 60 °. When the lens 13 is a telephoto lens, the horizontal angle of the telephoto lens is 15 ° to 30 °, and the monitoring range of the camera system 100 is 75 ° to 90 °, which can meet the monitoring requirement under most conditions, and is equivalent to wide-angle monitoring, i.e., long-distance and large-range monitoring of the camera system 100 can be achieved.

In the present embodiment, the distance between the flat surface portion 82 and the base portion 79 is defined as: when the lens assembly 11 tilts and rotates to the maximum depression angle and the maximum elevation angle, the point where the optical axis intersects with the reflector assembly 12 is located in the mirror surface of the reflector 17, and the shooting range of the lens 13 completely falls in the mirror surface of the reflector 17, so that all incident light rays in the field angle range of the lens 13 can enter the lens 13 through the reflector assembly 12, and the occurrence of incomplete display pictures is prevented.
