How to achieve the night vision effect of explosion-proof cameras is a small problem currently faced by high-definition network explosion-proof cameras. However, the infrared night vision effect is also a major indicator to consider the quality of a monitoring camera. In particular, the pixels used in explosion-proof high-definition network cameras are much higher than those used in simulation. In order to achieve better video effect with high pixels, most manufacturers use ircut to control infrared rays during the day and at night, and use infrared lamps with higher power, so that the daytime effect is better, but at night, power supply shortage is easy to occur. How can the night vision effect of explosion-proof cameras be improved?  1. Directly use the 220v power cord to the explosion-proof camera end and use a small 12v switching power supply to supply power;  This scheme is troublesome to wire, but the power line diameter can be relatively small. Better dc12v adapter should be used. Never use inferior adapter n"k9nm.  2. Use the power cord with thicker wire diameter to supply DC centralized power to the explosion-proof camera.  The scheme is relatively reliable, but the power line is relatively thick and the line cost is relatively high.  3. If the distance is not too long, such as 30m, 4-5 and 7-8 wire pairs can be used to transmit dc12v, thus doubling the cross-sectional area of the transmission line and significantly improving the power supply quality of explosion-proof cameras.  If used properly, the comprehensive benefit is relatively high. 4. The centralized power supply terminal uses a dv24-48v switching power supply and supplies power through a network cable, and the anti-explosion infrared high-definition network camera is reduced to dc12v by adding a step-down module.  The scheme needs a certain circuit foundation.  However, the cost is the lowest and the reliability is relatively high. Compared with high-definition network monitoring explosion-proof cameras, sdi high-definition explosion-proof cameras have the advantages of no compression, low delay and easy installation, which are beyond the reach of high-definition network explosion-proof cameras, and are also favored by engineers and users.  The image compression of sdi HD explosion-proof monitoring camera is at the back end of the monitoring system. Since there is no compressed packet process without ip transmission, the image becomes more realistic and the data security becomes higher.  In addition to the normal function of capturing monitoring images, the explosion-proof cameras currently on the market actually do not win by definition. The most important thing is to capture the position through images, which can capture moving targets through thermal imaging technology. This laser infrared enhancement fusion technology can capture images in zero light, track "hot objects" and perform detection well.  Changzhou Phoenex Electronic Technology Co., Ltd.-A professional manufacturer produces explosion-proof camera www.czfnkz.com, explosion-proof monitoring, explosion-proof camera, explosion-proof infrared camera, explosion-proof zoom camera, explosion-proof integrated camera, explosion-proof shield, explosion-proof high-speed ball, explosion-proof monitoring video monitoring system
