How to improve the night vision effect of explosion-proof cameras is a small problem faced by current high-definition network explosion-proof cameras, but the infrared night vision effect is also the main indicator to consider the quality of a surveillance camera, especially the pixels used in explosion-proof high-definition network cameras are much higher than those in simulations. , in order to make high-pixel video effects better, most manufacturers use IRcut to control infrared rays during the day and night, and use higher-power infrared lights. This way, the effect is better during the day, but at night, insufficient power supply is prone to occur. .So how to improve the night vision effect of explosion-proof cameras?

1. Directly connect the 220V power cord to the explosion-proof camera and use a small 12V switching power supply. This solution is troublesome to wire, but the diameter of the power cord can be thinner. You need to use a better DC12V adapter. Do not use inferior quality adapters. DeviceN"K9nM.

2. Use a power cord with a thicker diameter to provide centralized DC power supply to the explosion-proof camera. This solution is more reliable, but the power cord is thicker and the line cost is relatively high.

3. If the distance is not too long, such as 30M, 4-5 and 7-8 line pairs can be used to transmit DC12V. This doubles the cross-sectional area of the transmission line and can significantly improve the power supply quality of explosion-proof cameras. If used properly, the overall benefit is relatively high.

4. The centralized power supply terminal uses DV24-48V switching power supply, which is powered through the network cable. After reaching the explosion-proof infrared high-definition network camera, a step-down module is added to reduce it to DC12V. This solution requires a certain circuit foundation. But the cost is the lowest 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 beyond the reach of high-definition network explosion-proof cameras and are 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 packet process without IP transmission, the images appear more realistic and the data security becomes higher.
In addition to the normal surveillance image capture function, the explosion-proof cameras currently on the market do not win with clarity. The most important thing is to obtain the position through the image. This can capture moving targets through thermal imaging technology. This kind of laser infrared enhancement The fusion technology achieves image capture under zero light, has the ability to track "heat-generating objects", and effectively completes the detection function.
