How to test the effect and selection plan of the camera

Since the beginning of the 21st century, the application of security monitoring systems has been widespread, from the initial enterprises, government agencies to the popularization of civilian use, from a single early step toward diversified design. The camera is divided into black and white and color. Because the black and white camera has the advantages of high resolution and low illumination, especially it can be imaged under infrared light, so in the television monitoring system, the black and white CCD camera still has a high market share. But in the home monitoring system, the majority of users choose color cameras.

Cameras are divided into gun cameras, infrared cameras, integrated cameras, zoom cameras, dome cameras, smoke cameras, etc., but only a few of them are used in home monitoring, everyone should have a preliminary understanding.

There are many types of surveillance cameras, and there are many cameras with high imitation technology on the market. Cameras of various manufacturers and brands, but the ultimate goal of the engineering company is to make a better technical solution. When choosing a camera, you must choose from the most important elements of monitoring. So, how can you Really test the real effect of the camera?

According to the situation, how to test the imitation Samsung surveillance camera: In fact, the choice of CCD chip, like the human retina, is the core of the camera. In general civilian-grade imitation Samsung cameras are 420 lines, 480 lines, 540 lines, 600 lines, 700 lines, representing the clarity of the camera, at the time of purchase, you can take the following methods to detect: turn on the power, connect the video cable to the monitor , Close the lens aperture to see if the bright spot image is completely black. There is no such big snow on the screen. This is the easiest way to detect the CCD chip and does not require special instruments. You can then open the iris to see the optimal intake of a still life, a color camera, and brightly colored objects, and see if the actors on the display are smooth, distorted, colored, or grayscale. A good CCD can restore color scenes well, display objects with clear and natural effects, and the defective product image will have a color cast phenomenon. Even when facing a blank piece of paper, the image will be displayed in blue or red.

Another thing to note is to open the iris, watch a still life, a color camera, the best intake of brightly colored objects, and see if the actors on the display are smooth, distorted, colored, or grayscale. A good CCD can restore color scenes well, display objects with clear and natural effects, and the defective product image will have a color cast phenomenon. Even when facing a blank piece of paper, the image will be displayed in blue or red. Due to the dust and impurities in the production workshop of the personal CCDCCD target, under normal circumstances, the impurities will not affect the monitoring and installation of the image Daxing District, but in low light or microscope cameras, fine dust can also cause undesirable consequences.
