How to improve the night vision effect of explosion-proof camera?
How to improve night vision video camera explosion, is a small problem the current high-definition network video camera facing the explosion, but also consider the effect of infrared night vision surveillance cameras main indicator of good or bad, especially with the explosion of high-definition network camera which pixels than analog In order to make the high-pixel video effect better, most manufacturers use IRcut to control the infrared light during the day and night, and use infrared lamps with higher power, so the daytime effect is better, but at night, it is easy to supply power Insufficient phenomenon. So how to improve the night vision effect of explosion-proof camera?
1. Directly use the 220V power cord to the end of the explosion-proof camera, use a small 12V switching power supply; this solution is troublesome, but the power cord diameter can be thinner, and a better DC12V adapter must be used. Do not use inferior quality Adapter N "K9nM.
2. Use a thicker power cord to provide DC power supply to the explosion-proof camera. This scheme is relatively reliable, but the power cord 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, so the cross-sectional area of ​​the transmission line has doubled, and the power supply quality of the explosion-proof camera can be significantly improved. If used properly, the comprehensive benefit is relatively high.
4. The centralized power supply terminal uses a DV24-48V switching power supply to supply power through a network cable. After the explosion-proof infrared high-definition network camera is added, a buck module is added to reduce it to DC12V. The program needs to have a certain circuit foundation. But the cost is low and the reliability is relatively high.
Compared with high-definition network surveillance explosion-proof cameras, SDI high-definition explosion-proof cameras have the advantages of no compression, low latency, and easy installation. These are unmatched by high-definition network explosion-proof cameras, and are also favored by engineering companies and users. The image compression of SDI high-definition explosion-proof surveillance cameras is at the back end of the surveillance system. Since there is no compression and compression process without IP transmission, the image becomes more realistic and the data security becomes higher.
In addition to the normal monitoring image capture function, the existing explosion-proof cameras on the market now do not win with clarity. The important thing is to obtain the position through the image. This can capture moving targets through thermal imaging technology. This laser Infrared enhanced fusion technology achieves image capture under zero light, has the ability to track "hot objects", and completes the detection function well.
Deep Groove Ball Bearing is the most representative structure in rolling bearing, which is widely used. In addition to radialload, this kind of bearing can also be loaded with bidirectional axial load. The friction torque is small, and it is most suitable for adjusting rotation, low noise and low vibration. Bearings are widely used in automobile, electrical, instrumentation,construction machinery, agricultural machinery and various professional machinery. This kind of bearing has open and closed deformation structure.
