Focus the surveillance camera
If it was a general non-integrated surveillance camera, the method of adjusting the focal length was as follows: First, remove the camera, check the small screw like parts at the lens and loosen it, then turn the circle on the lens to adjust the focal length. When adjusting the focal length, it was best to take it off and adjust it while facing the monitor screen. If it was inconvenient to take it off, two people were needed. One person looked at the screen and cooperated with gestures or words, and the other person adjusted it next to the camera to achieve the best effect. It could also be adjusted manually. Some surveillance cameras had two buttons that could be rotated. One was used to adjust the distance and the other was used to adjust the clarity. There was another adjustment method: first loosen the fixing screw of the camera's rear focal length adjustment ring; adjust the zoom lens to the maximum telephoto position, and use the focal length adjustment ring on the lens to set the focal length until the image is the clearest; then adjust the zoom lens to the maximum wide-angle position, and turn the rear focal length adjustment ring until the image is the clearest; when switching from telephoto to wide-angle, repeat the above two steps until the image is in focus; finally, after the setting is complete, tighten the rear focal length adjustment ring. In addition, he added a new experience of adjusting the lens. He loosened the screw that fixed the standard lens, adjusted the magnification, and adjusted the lens to a telephoto state. Then, he zoomed in on the distant object, and then adjusted the focal length to make the close-up image clear. Then, he pulled the lens back to the wide-angle state by zooming out. The image he just shot should be a panoramic view. Don't adjust the focal length of this panoramic view (even if the image is blurry, don't adjust it). Go straight to the next step, which is to adjust the back focal length to adjust the image to the best picture. Finally, tighten the small screw of the lens, and the back focal length adjustment is completed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The surveillance camera on the highway?
The video surveillance on the highway might have a camera function. For example, the violation camera was generally spherical in shape. Its function was to capture and punish the captured vehicle.

Surveillance camera aperture means
In terms of concept, the aperture was a device in the surveillance camera that controlled the light passing through the lens and adjusted the light sensitivity inside the camera. In terms of structure, it was controlled by the amount of light passing through the lens. Usually, the F-value was used to express the size of the aperture. In daily life, 1.0, 1.2, or 1.4 would be used to represent the aperture size of the lens. When the F-value was smaller, the larger the aperture was, and the more light the sensor chip could pass through. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
