Description

technical field

[0001] The invention relates to a camera with a rotatable angle, in particular to a dome camera which uses a single motor to change the rotation angle of a photographing lens. Background technique

[0002] The dome camera in the prior art usually uses two motors in order to make the photographic lens move in all directions (360°) to track the object and take images, and one of the motors controls the photographic lens to move left and right (pan ) to move, and the other motor is used to control the tilting of the camera lens vertically in the left and right directions (tilt), so that the camera lens can move in both left and right and up and down directions.

[0003] However, the disadvantage of this dome camera is that two motors are used to control the left to right movement and the upward and downward movement of the photographic lens respectively. Guide to desired fixed point. Therefore, when the dome camera rotates the camera lens to scan the surroundi...
