Monitor is a closed-circuit surveillance system (cctv) component of the monitoring system of professional LCD monitor equipment used in security surveillance, the product passed CCC, CE, FCC, ROSH and other global market acceptance of the certification. 
 Shows part of the monitoring system standard output, with the monitor shows that we can watch the images sent from the front. Essential as video surveillance terminal device, as the monitoring personnel "eyes", but also for post-survey respondents play a key role. 
 Monitor closed circuit monitoring system as a display terminal, is in addition to the camera monitoring system outside the integral part. For a long time monitors are used in finance, jewelry stores, hospitals, subways, stations, airports, exhibition of, commercial offices, leisure and entertainment, etc., responsible for security work. In recent years, due to technology, the cost of whole CCTV system has been well adjusted. More and more small businesses also have affordability, began to establish its own monitoring system to achieve security or other monitoring requirements.

 Qinghai monitor, monitor manufacturers Qinghai, Qinghai LCD monitor, LCD monitor factory in Qinghai Qinghai monitor, monitor manufacturers Qinghai, Qinghai LCD monitor, LCD monitor and display the Qinghai difference: 
 First, the use of different materials: computer monitors and monitors for video rate, the meaning is completely different monitors using the "short afterglow tube" and the monitor is used "in the afterglow tube" (both used in phosphors, and significant management recognition of color is fundamentally different, usually smaller display, though they have a higher pitch or vertical refresh rate, but the display used in "short afterglow tube" of color recognition is equivalent to monitor "in the afterglow tube "about 1 / 5). A high-end monitor phosphors used only its own is enough to sell a few high-end monitors. Displays itself mainly as a "still image" service, which is mainly used to display images and text, and special application environments coordinates (strictly speaking, not good performance of the mobile display images (note the image on the image with the real difference). 
 The monitor is designed specifically for video, it does not emphasize the display of concepts such as pitch or vertical refresh rate, but the harsh emphasis on color recognition and identification capabilities (required for the performance of the image is absolutely neutral, natural, accurate, broadcast color monitor and color images does not allow the slightest distortion and color cast). 
 Second, the input signal is different: the color monitor AV input analog video signal, RGB RGB computer monitor to the VGA input digital signal. 
 Third, the resolution is different: ordinary color monitor is usually 420 lines or 480 lines and the computer the monitor is 800 * 600 resolution. 
 Fourth, the radiation to different degrees: some do not color monitor radiation treatment (some manufacturers in order to make the image more clearly, increase the line deflection voltage, resulting in electrostatic radiation), and computer monitors must have a radiation detection certification, or simply using the LCD monitor no radiation. 
 Five different refresh rate: Normal color monitor refresh rate should be 50Hz or less (analog), the average computer monitor easy to 75hz. 
 Seven different anti-jamming capability: Monitor the design current, power, temperature, and anti-radio interference, electrical shocks and redundancy and the average time of trouble-free use have to be much larger than the display. At the same time monitor must use fully shielded metal enclosure to ensure electromagnetic compatibility and interference performance. 
 Eight, to restore the signal in different ways: video camera when the optical signal is converted to RGB signals. By the middle of the matrix circuit part of the camera, RGB initial conversion of electrical signals, converted to Y / RY / BY signals. The monitor is just the process of imaging the corresponding matrix by the matrix circuit and circuit cameras as a matrix conversion value of this counter-process to the original image signal will not be able to reproduce them faithfully presented. The VGA input, does not consider the camera image restore problem, not as good as the monitor in the reduction degree
