1、 The camera should be installed near the monitoring target where it is not easy to be damaged by the outside world. The installation position should not affect the operation of on-site equipment and normal activities of personnel. The installation height should be 2.5 ~ 5m from the ground indoors; The outdoor shall be 3.5 ~ 10m from the ground and shall not be less than 3.5m.

2、 The camera in the elevator car shall be installed at the top of the elevator car and the opposite corner of the elevator operator, and shall be able to monitor the panoramic view in the elevator car.

3、 The camera lens shall avoid direct strong light to ensure that the target surface of the camera tube is not damaged. There shall be no object blocking the monitoring target in the field of view of the lens.

4. The camera lens shall aim at the monitoring target from the direction of light source, and backlight installation shall be avoided; When backlight installation is required, the contrast of the monitoring area shall be reduced.

5. The camera shall be installed near the monitoring target where it is not vulnerable to external damage. The installation height is 2.5 ~ 5m from the indoor ground; The outdoor distance from the ground shall be 3.5 ~ 10m, not less than 3.5m.

6. The camera in the elevator car shall be installed on the top of the elevator at the opposite corner of the elevator operator; The optical axis of the camera forms a 45 ° angle with the two walls of the elevator and a 45 ° depression angle with the elevator ceiling.

7. The camera lens shall aim at the monitoring target along the direction of the light source.

The commissioning method after the monitoring project is installed is as follows:
① Open the automatic electronic shutter function of the camera;
② Adjust the lens aperture to the maximum with the controller;
③ Aim the camera at an object 30 meters away and focus to infinity (most lenses face the lens and rotate the front focus adjustment ring clockwise to the end);
④ Adjust the zoom of the lens with the controller to push the scene furthest, and adjust the rear intercept of the lens to make the scene clearer;
⑤ Use the controller to adjust the zoom of the lens to pull the scene closest, and fine tune the focus of the lens to make the scene most clear;
⑥ Repeat steps 4-5 several times until the scene is always clear during lens zoom.
