HD-SDI conference camera selection and installation issues
There are two kinds of cameras, black and white and color. Usually, the horizontal resolution of a black and white camera is higher than that of a color camera, and the black and white camera is more sensitive than a color camera, and is more suitable for places with insufficient light and places with dark night lights. However, colored images can easily distinguish the colors of clothes and scenes, which facilitates timely acquisition and differentiation of real-time information at the scene. Therefore, in order to meet our 24-hour all-day monitoring needs, we must choose a camera with color to black and white.
The definition of the HD-SDI high-speed dome camera is generally expressed in horizontal resolution. Horizontal definition represents a measure of the level of detail sharpness of the human eye to a television image, represented by a television line. At present, the horizontal resolution of high-speed dome cameras on the market is mostly online. The higher resolution cameras are more conducive to capturing the details of objects. Therefore, high-definition cameras are important parameters for equipment selection.
The camera's sensitivity is expressed in terms of the minimum illuminance, so in reality the illuminance of the subject is approximately more than the minimum illuminance to obtain a clearer image.
Now some manufacturers in the market have launched HD optical zoom optical HD-SDI high-speed dome camera, its maximum focal length is around, its effective monitoring distance to effectively increase the monitoring distance indirectly saves costs, which is also what we need to consider One problem, so choose a large optical multiple when choosing a camera.
In some cases where the contrast between light and darkness is too large, the camera is generally limited by the photosensitivity of the camera, and the captured image tends to be too bright or the foreground is too dark. In response to this situation, wide dynamic technology came into being and solved this problem better. Therefore, when selecting a wide dynamic camera, it depends on the color contrast of the image and whether the manufacturer has the ability to develop a wide dynamic camera.
