In the rest state, the platform 2 can be understood as a stationary table and is therefore not limited to the literal meaning described in the present embodiment. When it needs to rotate, this embodiment provides a drive division that is used for driving platform 2 to do horizontal rotation, and the drive division is the base 1 that embeds there is the motor, and motor shaft and platform 2 coaxial arrangement are used for accomplishing the rotation of platform 2 in the horizontal plane, and the maximum rotation angle of platform 2 is 360. For ease of understanding, the structure of the platform 2 and the drive may be thought of as a rotatable head. On the other hand, in order to achieve close-up image acquisition of the abnormal moving target, that is, to acquire an ultra-high definition image of the abnormal moving target, the second camera 3 must be aligned with the abnormal moving target, and therefore, the pitch angle of the second camera 3 needs to be adjusted. More specifically, the pitching adjusting mechanism comprises a driving motor and a horizontal rotating shaft 7, the bottom of the second camera 3 is hinged to the horizontal rotating shaft 7, and the driving motor is used for driving the horizontal rotating shaft 7 to rotate to complete pitching angle adjustment of the second camera 3.
