IR Speed Dome purchase Notes <br> <br> angle questions: First, a large degree view of the infrared light with the overlooked angle lens, there is waste of light. Second, the larger the angle of emission of the infrared light, the better the picture.
The problem of the amount of light flux: The relative aperture determines the light transmission capability of the lens, and the lens light flux of the relative aperture f1.0 is four times the light flux of the lens of the relative aperture f2.0. The same camera, infrared light, respectively, with the above two lenses, infrared action distance can be doubled. Large-aperture lenses are four to ten times better than conventional lenses in infrared surveillance, but they are expensive and technically difficult.
Focus shift problem: visible light and infrared light due to different wavelengths, imaging focus is not on a plane, resulting in clear images in the daytime visible light conditions, and nighttime infrared light conditions blurred, or nighttime infrared light conditions, clear images, daytime visible light conditions The image is blurred. The automatic focusing integrated camera can avoid focus shift, adopting a special focus without shifting the lens or adopting a professional adjustment tool to achieve no shift under the existing lens conditions.
Color problem: All black and white cameras are infrared sensors. Infrared light will reduce the clarity and color reproduction of color cameras in visible light conditions. Color camera filters can effectively prevent infrared light from participating in imaging. The switch filter is used to block the infrared light from entering under visible light conditions. If the filter is removed without visible light and the infrared light enters, the resulting image will be of good quality but the cost will be high and the switching mechanism will cause a certain failure rate.
Infrared High Speed Dome operation using the method of using a high-speed ball and some important details <br> <br> infrared array intelligence, let you quickly and easily operate an array of infrared intelligent high-speed ball.
The first step: After you get the smart speed dome, remember to take care of the whole process. Because you love your smart speed dome, it will "return" you, that is the lower failure rate, longer life.
The second step: Many people like to use their hands to raise the core of the intelligent high-speed ball during the installation process. Xiaobian recommends that the core of the intelligent high-speed ball be connected to the conductive slip ring interface. It is easy to lift the core wire. It is very easy. Bad interface occurs, the best way is to use your hands to hold the smart high-speed ball.
The third step: During the installation process, the power cable must be led near the intelligent high-speed ball. At the same time, the line of the power adapter of the intelligent high-speed ball should not be extended, and the centralized power supply mode should not be used. Reasons The intelligent high-speed ball centralized power supply, sometimes the voltage to the intelligent high-speed ball will be insufficient, especially in the thunderstorm weather, the resistance resistance increases, the insufficient power supply may cause the motherboard of the intelligent high-speed ball to burn, and thus cannot be controlled.
Step 4: When wiring, remember to distinguish RS485 protocol communication line and power line. If RS485 is connected to the power supply, the intelligent high-speed ball may be burned on the spot, so do the relevant identification, to facilitate their own convenient future maintenance.
Step 5: When installing, the 220V power line must be led to the dome. Do not extend the line of the power adapter equipped with the dome. It is even more impossible to use centralized power supply. Extending the power line or centralized power supply, the voltage to the dome will be insufficient, especially in the rainy days, the line resistance will increase, resulting in insufficient power supply to the dome, and the capacitance of the main control board of the dome will continue to discharge, which may cause the dome board to burn out. , there is no control.
Step 6: The use of smart speed domes in indoor environments is completely different from that in outdoor environments. When installing outdoors, strict waterproofing must be performed. Usually, if there is no professional construction, it is not recommended to lift it outdoors. If you think so, it doesn't matter. I hit glass glue and it's sealed. The Xiao Bian may not agree with it. The gap between glass glue and the intelligent high-speed dome of finance seems to be sealed. However, when you look closely, there is still a small gap, and water is very likely to seep into the dome. The impact of high-speed ball is very large.
Step 7: Test the smart speed dome. It is important to choose the right power source. Why? If the power is too high, the intelligent high-speed ball will be burned. If the power is too low to reach the rated power of the intelligent high-speed ball, the capacitance of the main control board of the intelligent high-speed ball will continue to discharge. This means that the components of the intelligent high-speed ball are The damage will shorten the life of the intelligent high-speed ball.
Step 8: Usually the above steps are successfully completed. The installation steps of the entire intelligent high-speed ball will be almost the same. Now all you have to do is to recheck whether the entire process is correct.
Talking about Infrared Speed ​​Dome Precautions and Operation and Use
With the development of the industry at any time, millions of HD have gradually become new demands of the market. The principle of high-definition infrared high-speed ball is based on the ordinary infrared high-speed ball, using the 1.3 million pixels or 2 million pixel HD high-definition integrated machine to replace the original SD integrated machine, while the high-definition video encoder is integrated on the high-speed ball motherboard, Make infrared high-speed ball into a pure digital network-type high-definition infrared high-speed ball.
