Referring to fig. 1 to 3, an embodiment of the present application discloses a camera including a first lens assembly 100 and a second lens assembly 200.

The first lens assembly 100 acts as an imaging member of the camera and can monitor one of the regions. The first lens assembly 100 includes a cantilever member 110 extending longitudinally and a first lens 120 disposed at the cantilever member 110. Alternatively, the cantilever part 110 may include a supporting plate and two cantilevers spaced apart from each other on the same side of the supporting plate, so that a space for accommodating the first lens 120 is defined between the two cantilevers and the supporting plate, and the first lens 120 is connected to the cantilevers. In some embodiments, mounting holes may be formed on the two cantilevers, and a rotation shaft may be formed on a sidewall of the first lens 120, and the rotation shaft may be rotatably disposed in the mounting holes, so that the first lens 120 may rotate with respect to the cantilever member 110. Further, the axis of the rotation shaft portion is horizontal, so that the pitching motion of the first lens 120 can be achieved. In order to enable the first lens assembly 120 to automatically perform the pitching motion, a driving element may be further added, and the driving element is in transmission connection with the rotating shaft portion, for example, a driving motor and the like, and the first lens assembly 120 may be driven to perform the pitching motion by the driving element, so that the range of the monitoring area of the first lens assembly 100 may be expanded.

The second lens assembly 200 is used as another image capturing component of the camera, which can monitor another area, and different areas can be monitored through the second lens assembly 200 and the first lens assembly 100, so as to expand the monitoring range. Referring to fig. 3, the second lens assembly 200 includes a housing 210 and a plurality of grooves 213 circumferentially disposed on a sidewall of the housing 210, wherein an end surface of the groove 213 near a middle portion of the housing 210 is opened with a through hole 214, and any one of the through holes 214 is used for disposing a second lens 220.
