Camera device with high-precision holder

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...

Problems solved by technology

[0004] However, according to the actual needs of the site environment, it is necessary to meet the needs of night monitoring, and to measure the distance between the monitored object and the camera by installing a radar, and to install a thermal imager. “eye” PTZ camera

This approach not only increases the cost of monitoring equipment, but also makes the construction process cumbersome and prone to failure
