Precautions for installation of explosion-proof video surveillance cameras

Unread post by vedard »

Explosion-proof surveillance camera has become an irreplaceable security equipment in special industrial production environment. Explosion-proof surveillance cameras are needed in chemical plants, gas stations, port docks, fireworks factories, military factories, coal mines, offshore drilling platforms and so on for security production and protection surveillance.
Special attention should be paid to the installation of explosion-proof monitoring cameras as follows:
1. The inlet of the explosion-proof camera must be sealed with rubber sealing ring, and it is forbidden to replace it with filling sealing cement, asbestos rope and other methods. Do not fill the cavity with anything. In order to avoid the loss of explosion-proof performance, the oil on the rubber sealing ring should be scrubbed clean to avoid aging and deterioration.
2. It is strictly prohibited to change the structure of the explosion-proof camera, parts and the internal circuit of the equipment.Fastening bolts shall not be replaced or missing at will. Elastic gaskets and metal gaskets at the inlet and outlet of the bolts shall be kept in the factory sealed state, and the pressing nut shall be tightened to seal the inlet.
3. The wiring is best dark line, if you can only go open line, it is necessary to ensure that the physical protection of the line part is the best.
4. Attention should be paid to avoid strong impact on the explosion-proof infrared camera during installation.Before installation, must confirm the power supply voltage is the specified voltage, so as not to burn out, the lens should not aim at the strong light, such as sunshine, lighting, etc., otherwise prone to over-bright phenomenon, the service life of CCD will also have a certain impact.The installation position of the explosion-proof infrared camera should also avoid humidity, dust, extremely hot, extremely cold, strong electromagnetic radiation and other places.
5. During daily operation and maintenance inspection, avoid opening the explosion-proof camera shell as much as possible, and cut off the power supply when it must be opened.If the flameproof shell is opened, the flameproof surface should be properly protected and shall not be damaged. The flameproof surface should be placed upward during maintenance and shall not directly contact the ground. After cleaning, the other scene should be coated with phosphating paste or 204 antirust oil.
6. explosion-proof infrared camera is based on CCD matching infrared light emission infrared light reflected on the object to the CCD camera lens imaging.Therefore, we should avoid the field of view when installing explosion-proof infrared cameras are all black objects and open places, water and other objects that absorb infrared light, if the infrared is absorbed or weakened, it will make the effective irradiation effect of the infrared lamp is greatly reduced, thus affecting the explosion-proof infrared camera monitoring screen effect.
