The analog camera is much more troublesome and costs more. Generally used in large factories.
Installation surveillance camera precautions:
1. The camera should be installed near the monitoring target and is not easily damaged by outside. The installation location should not affect the on-site equipment operation and normal personnel activities. The height of the installation should be 2.5 to 5 meters from the ground in the room; 3.5 to 10 meters from the ground in the room and not less than 3.5 meters from the ground.
2. The camera in the elevator car should be installed at the top of the elevator car and at the opposite corner of the elevator operator, and it should be able to monitor the panorama in the elevator car.
3. The camera lens should avoid direct light and ensure that the target surface of the camera tube is not damaged. Within the field of view of the camera, there must be no object that blocks the surveillance target.
4. The camera lens should be aimed at the monitoring target from the light source, and should avoid back light installation; when the back light installation is required, the contrast of the monitoring area should be reduced.
5. The camera should be installed near the surveillance target where it is not easily damaged. Installation height, indoor 2.5 ~ 5m from the ground; outdoor from the ground 3.5 ~ 10m, shall not be less than 3.5m.
6. The camera in the elevator car shall be installed at the top of the elevator at the opposite corner of the elevator operator; the optical axis of the camera shall be at an angle of 45° with the walls of the elevator and a depression angle of 45° with the elevator ceiling.
7. The camera lens should be aligned with the light source in order to monitor the target.
The method of debugging after installation is as follows:
1. Open the camera's automatic electronic shutter function;
2. Use the controller to adjust the lens aperture to maximum;
3. Point the camera at an object other than 30 meters, and focus at infinity (most of the lenses are facing the lens and rotate the front focus adjustment ring clockwise to the head);
4. Use the controller to adjust the lens zoom to push the subject to the furthest distance, adjust the lens back to make the scene the most clear;
5. Use the controller to adjust the lens zoom to pull the scene to the nearest, fine-tune the lens to make the scene the most clear;
6. Repeat steps 4-5 several times until the scene is clear during zooming.
1) Sharp cutting and processing;
(2) Diamond cutting pieces have high rigidity, high strength and long service life;
(3) The ultra-thin diamond cutting piece has high precision, which can be used for slotting machine cutting, and the incision is smooth without collapse;
(4) The continuous cutting of Valin diamond slices does not slip and does not appear the phenomenon of blade passivation;
(5) The diamond cutting slot is narrow, which can greatly improve the utilization rate of precious raw materials.
