If you judge the quality of the dome camera

[ Pacific Security Network News ]
At present, in our lives, the demand for monitoring is increasing continuously. Is there any doubt about the quality in the use of the hemisphere camera? This is necessary to carry out the necessary tests through the six major principles.
1. It is still necessary to test the color reproduction of the hemispherical camera. It is necessary to observe the color of the person and the clothing to see if there is any distortion. Make a unified and effective improvement mode for the sensitivity of the dome camera. Maintain a closest state of expression for the aperture.
2. The resolution of the other hemisphere camera should have a measurement. Through the improvement of the same lens, the circle of the center of the test card is used as the main reference object, and the clearest performance mode is achieved by the change of the left and right angles of the monitor screen. Represents the many improvements in vertical clarity and camera differences to make the necessary improvements and extensions.
3. In addition, the necessary improvement is made to the illuminance. The hemispherical camera should be placed in the dark room to carry out the necessary exploration. By processing the performance mode of the active incandescent lamp before and after, the regulator adjusts the voltage high to perform the relevant dark and dark adjustment of the dark room. The mode is to test the aperture of the hemisphere camera to the lowest illuminance by indoor illumination, and record the aperture to the lowest illuminance value.
4. Through the minimum illumination performance mode, the necessary exploration and summarization mode of the hemispherical camera power consumption is carried out, and the voltage is adjusted by using a small voltage regulator. The correlation generation of the image mainly comes from the CCD charge coupled device, and generally has a volume. Small and lightweight, and many other advantages, and will not be affected by the magnetic field.
5. For the distortion of the dome camera, the test card should be prevented from making necessary improvements at the front end of the camera to see if there is an ellipse in the sphere of the dome camera.
6. The last point is to make necessary improvements to the backlight compensation of the dome camera. In the case of sufficient sunlight, the hemisphere camera is illuminated to the outside of the window to see if the image and text are clear.
