How the explosion-proof camera night vision effect is a small problem facing the current high-definition network explosion-proof camera, but the infrared night vision effect is also a major indicator to consider the quality of a surveillance camera, especially the pixels used in the explosion-proof high-definition network camera is much higher than the simulation , In order to make high-pixel video better, most manufacturers use IRcut to control day and night infrared, and use more powerful infrared light, so that the daytime effect is better, but at night, prone to power shortage phenomenon How does the explosion-proof camera's night vision effect improve?
1. Use the 220V power line directly to the explosion-proof camera and use a small 12V switching power supply; this solution is troublesome, but the power line diameter can be smaller, you need to use a better DC12V adapter, do not use poor quality N" K9nM.
2. Use a thick-gauge power cord to provide DC power for explosion-proof cameras. This scheme is more reliable, but the power cord is relatively thick and the line cost is relatively high.
3, the distance is not too long, such as 30M, can use 4-5 and 7-8 pairs to transmit DC12V, so that the transmission line cross-sectional area doubled, can significantly improve the quality of explosion-proof camera power supply. When used properly, the overall benefit is relatively high.
4. The centralized power supply uses the DV24-48V switching power supply to supply power through the network cable. After the explosion-proof infrared high-definition network camera, the buck module is added to reduce the DC12V use. The program needs a certain circuit basis. But the lowest cost and higher reliability.
Compared to HD network surveillance explosion-proof cameras, SDI HD explosion-proof cameras have the advantages of no compression, low delay, and easy installation. These are all unmatched by the high-definition network explosion-proof cameras, and are also favored by engineering companies and users. The image compression of SDI HD explosion-proof surveillance cameras is at the back end of the surveillance system. Since there is no compressed packet process without IP transmission, the image becomes more realistic and the data security becomes higher.
Except for explosion-proof cameras already on the market, in addition to the normal surveillance image capturing function, explosion-proof cameras do not win by definition. It is important to obtain the position through the image. This can capture moving targets through thermal imaging technology. This type of laser infrared enhancement The fusion technology has achieved image capture under zero light, and it has been able to track “heat-generating objects†and completed the detection function well.
