The History Exhibition Hall of the Communist Party of China is located at No. 9 Beichen East Road, Chaoyang District, Beijing. Each red venue is a condensed history and a spiritual inheritance. Since it was opened to the public, it has received extensive attention from the vast number of cadres and masses, and has become a red check-in spot. In this project, Tianchuang Group built a video system for the History Exhibition Hall of the Communist Party of China.
Project requirements
The system designed by Tianchuang engineers for the red hall adopts two sets of broadcast box cameras Panasonic AK-UB300MC, both of which are planned to be installed on the back wall in the form of wall mounting, one of which is used as a close-up of the rostrum and the other as a panoramic shot of the rostrum. In addition, the system is also equipped with 4 PTZ integrated cameras Panasonic AW-HE65SKMC at the side wall and corridor to meet the multi-angle monitoring needs of the entire room. The overall system adopts the form of 2+4, which realizes the needs of all-round video acquisition and shooting.
However, in the construction process, due to the simple way of the overall decoration design style, the way of hanging and installing the rear wall was not adopted, and it needed to be replaced by other ways.
solution
In the process of looking for other installation methods, Tianchuang engineers found that the location of the control room was on the second floor above the back wall opposite the rostrum, which was above the original design wall mounting position, so the installation direction was consistent with the design, but the shooting distance and angle also needed to be considered. Through the drawing calculation, the shooting distance only increased by about one meter, almost no effect, the shooting angle for the original position, the pitch angle increased from 3 ° to 8 °, in line with the GB50635 national standard requirements of ≤ 10 °, to ensure the overall aesthetics of the room at the same time, but also meet the national standard, finally, 2 sets of Panasonic AK-UB300MC cameras installed in the control room, using a floor tripod placement.
Since the original design is gimbal wall mounting, the control of the camera can be operated by controlling the keyboard remote control gimbal, after modifying the installation position, the original gimbal can not be installed, using the form of floor tripod placement, in this way, the control of the camera needs to be manually adjusted. The camera back focus is adjusted and corrected by the Siemens star card, and all the required control functions and usage methods can be realized by adjusting the focus ring, zoom ring and aperture ring.
Acceptance
Through the introduction of the function of the system and the training of use, Party A has an understanding of the use of the camera, and through manual control, it can also meet the use requirements for conference shooting, and Party A is satisfied with the effect and meets expectations.
