Explosion proof cameras belong to the category of explosion-proof monitoring products and are a cross product of the explosion-proof industry and the monitoring industry. Because conventional camera products cannot be used in high-risk flammable and explosion-proof sites, explosion-proof cameras with explosion-proof functions are needed. Today, I will share with you how to install explosion-proof cameras and what things to pay attention to
How to install explosion-proof cameras
1. Under the condition of satisfying the requirements of the supervisory policy for the field of view size, the installation height of the explosion-proof camera indoors should be between 2-5 meters, and outdoors should be between 3-5 meters; The device inside the elevator car is installed at its top, diagonally opposite to the elevator operator, and the optical axis of the explosion-proof camera is at a 45 degree angle to the two walls and ceiling of the elevator.
2. Explosion proof cameras and their supporting devices should be protected from damage and harmonious with the surrounding environment.
3. In a strong electromagnetic interference environment, the camera device should be insulated from the ground.
4. Outdoor devices should adopt lightning protection measures.
5. The explosion-proof camera device must be sturdy to avoid shaking of the monitoring image.
6. Debugging infrared lights is necessary at night. Adjust the infrared beam illumination direction at night through imaging devices such as supervisors. And it can effectively adjust the lens aperture setting.
7. The reflectivity decreases when the elevation angle is too high. Too high will affect the reflectivity of light. The optimal viewing angle should be 20 degrees from top to bottom, and the height of the infrared light device should not exceed 4 meters,
8. Explosion proof infrared cameras should avoid direct light sources as much as possible, because the power control part of the infrared lamp is based on the photoresistor installed on the infrared lamp board to control whether the operating power of the infrared lamp is turned on or off.
9. The field of view of explosion-proof infrared cameras should try to avoid objects that absorb infrared light, such as completely black objects, open spaces, and water. The infrared lamp that comes with CCD cameras reflects infrared light onto objects and forms a picture on the CCD camera lens. If the infrared light is absorbed or weakened, it will greatly weaken the useful illumination effect of the infrared lamp. For example, the power supply power of the infrared lamp needs to be higher than its own operating power.
10. It is necessary to ensure the operation target of the infrared lamp (see product manual for details),
11. Users should carefully read the user manual when using infrared lights, especially the precautions to ensure personal and equipment safety. Check whether the compatibility mentioned earlier meets the requirements and whether the influencing factors that should be considered have been taken into account. If the requirements are not met, adjust the equipment used in a timely manner.
12. During the installation process, be careful not to touch the lens or CCD target surface with your hands, and do not let dust float onto the camera.
13. The device of the gimbal:
1) The device of the gimbal should be sturdy and not shake when rolling.
2) According to the product skill requirements and system planning requirements, the rolling viewpoint scale of the gimbal should be checked to see if it meets the requirements.
3) The decoder should be installed near the gimbal or in the ceiling (but with access holes left).
14. Avoid exposing equipment to large motors such as elevators, water pumps, and fluorescent columns, as well as various high-power wireless devices.
