Example Embodiment

[0018] The present invention will be further described in detail below with reference to the drawings and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0019] A high-precision pan-tilt camera device, such as figure 1 As shown, the chassis 4, the horizontal rotation component 3, and the cavity 1 are mounted with a horizontal rotation component, and the horizontal rotation component is respectively installed with two cavities, and the two cavities are symmetrically arranged. Two windows 2 are vertically installed up and down on the front side of the cavity.

[0020] In this embodiment, two vertical windows are installed on the front sides of the two cavities, and the two windows on the left are respectively installed with cameras (not shown in the figure) for capturing images and for night An infrared lamp (not shown in the figure) that provides the light source ...

Abstract

The invention relates to a camera device with a high-precision holder, comprising a chassis, a horizontal rotating assembly, and cavities. The horizontal rotating assembly is installed on the chassis. The horizontal rotating assembly is equipped with two cavities which are arranged symmetrically. Two windows are installed vertically on the front side of each cavity, with one above the other. The driving circuit of the device comprises a microprocessor module, a first driving circuit, a second driving circuit, a first motor, a second motor and a holder output shaft. According to the device, a camera, an infrared lamp, a thermal imager, radar, a visible light lamp and other equipment can be randomly combined and integrated as a whole according to different demands of users. The two motors act on the same horizontal transmission shaft under the control of the microprocessor, the position precision of the holder is improved through torque confrontation of the two motors, and the position precision of the horizontal transmission shaft is substantially improved.

Description

technical field [0001] The invention belongs to the field of video security monitoring, in particular to a high-precision pan-tilt camera device. Background technique [0002] Intelligent security pan / tilt is widely used as the front-end equipment of the security monitoring system. A key technology of the intelligent security pan / tilt is position accuracy. Since the transmission system of the pan / tilt includes gears, worm gears and other transmission mechanisms, the gears, worm gears, etc. in the transmission system must retain a certain gap in order to ensure that the motion can be transmitted. This kind of gap in the system is difficult to eliminate, therefore, the position accuracy of the pan / tilt stays at a low level, and its position accuracy is also difficult to improve. [0003] People have more and more requirements for its functions, such as the requirement to get a clear picture at night without lighting, so the "binocular" PTZ camera came into being, that is, the...
